FAA Grounds Boeing DC10 and MD11 Fleets Over Safety Concerns
FAA issues emergency directive grounding Boeing DC-10 and MD-11 fleets after UPS MD-11 engine pylon detachment incident in 2025.

FAA Grounds DC-10 and MD-11 Fleets with Emergency Directive
In a decisive move to ensure aviation safety, the U.S. Federal Aviation Administration (FAA) issued an Emergency Airworthiness Directive (EAD) on November 14, 2025, effectively grounding a significant portion of the global Cargo-Aircraft fleet. The directive, numbered 2025-23-53, mandates immediate and prohibitive action for all operators of Boeing DC-10, MD-10, and MD-11 aircraft. This order prohibits further flight until a critical inspection of the engine pylon attachments is completed and any necessary corrective actions are taken. The move underscores a swift response to a developing safety concern that has historical parallels to one of the most infamous accidents in U.S. aviation history.
The directive is not an isolated event but an expansion of a previous order. Initially, on November 8, 2025, the FAA had issued EAD 2025-23-51, which was limited to the MD-11 and MD-11F models. This first step was a direct reaction to a serious incident on November 4, 2025, involving a UPS MD-11. During its takeoff roll, the aircraft’s left-hand engine and its entire pylon assembly detached from the wing. Recognizing that the underlying structural design might pose a risk to related aircraft models, the FAA broadened the scope of its mandate. The new, superseding directive now includes a wide range of DC-10 variants, signaling the agency’s concern that a potentially critical Safety issue could affect the entire aircraft family.
A Closer Look at the Directive and Its Catalyst
The language of EAD 2025-23-53 is direct and leaves no room for interpretation. It explicitly states that further flight is prohibited for all affected models until the required inspections and repairs are performed. The compliance time is immediate upon receipt, a measure reserved for the most serious airworthiness concerns. The directive covers a long list of venerable workhorses of the air cargo industry, including the MD-11, MD-11F, MD-10-10F, MD-10-30F, and multiple variants of the DC-10, from the -10 series to the -40 series, including Military-Aircraft KC-10A and KDC-10 tankers. This broad applicability highlights the FAA’s concern over a shared design element across these platforms.
The UPS Flight 2976 Incident
The chain of events leading to this widespread grounding began on November 4, 2025. A UPS MD-11, operating as Flight 2976, experienced a catastrophic failure during takeoff when its left engine and pylon separated from the aircraft. While the investigation by the National Transportation Safety Board (NTSB) is still ongoing, the nature of the failure was alarming enough to trigger an immediate response. The FAA’s initial directive noted that such a condition could result in the “loss of continued safe flight and landing.” The core of the investigation now focuses on what caused the pylon structure to fail, whether it was an engine malfunction that led to the separation or a pre-existing issue with the pylon itself.
In a proactive step, even before the FAA issued its first directive, Boeing had reportedly recommended that the three primary operators of the MD-11 freighter, FedEx, UPS, and Western Global, suspend their flight operations pending further analysis. This indicates a consensus between the manufacturer and the regulator that the potential risk was too significant to ignore. The grounding of the MD-11 fleet alone impacted approximately 109 U.S.-registered aircraft, causing significant disruption to global logistics and supply chains that rely heavily on these long-haul freighters.
The FAA has justified its decision to bypass the standard notice and public comment period typically associated with rulemaking. Citing the severe risk to public safety, the agency classified the EAD as an “interim action.” This allows the FAA to address the immediate threat while the NTSB’s investigation continues. Further rulemaking or additional directives may follow once the root cause of the UPS pylon failure is definitively identified.
The FAA has determined that other aircraft models with a similar engine-pylon design were also at risk, leading to the issuance of the superseding EAD 2025-23-53.
Echoes of American Airlines Flight 191
For aviation historians and safety experts, the recent events evoke a chilling sense of déjà vu, drawing a direct line to the tragic crash of American Airlines Flight 191 in May 1979. In that accident, a DC-10 taking off from Chicago’s O’Hare International Airport experienced the separation of its left engine and pylon. The detachment severed hydraulic lines, leading to an uncommanded retraction of the left wing’s leading-edge slats and a subsequent catastrophic loss of control. The incident remains the deadliest single-aircraft accident in United States history.
The NTSB investigation into Flight 191 uncovered that the pylon separation was not due to a design flaw but was the result of maintenance-induced structural damage. American Airlines had been using a non-standard procedure to save time, removing the engine and pylon as a single unit with a forklift. This process inadvertently created a crack in the pylon’s rear bulkhead, which grew with each flight cycle until it failed. The fallout from the 1979 crash was immense, leading the FAA to temporarily suspend the DC-10’s type certificate and issue multiple airworthiness directives to prevent a recurrence.
While the cause of the 2025 UPS incident is still under investigation, the physical similarities of the failure, the complete separation of the engine and pylon from the wing, are undeniable. This historical precedent provides critical context for the FAA’s swift and expansive action. The agency is not just responding to a single incident but to the demonstrated potential for a catastrophic outcome if a similar structural failure were to occur again, especially during a critical phase of flight.
Conclusion: A Precautionary Principle in Action
The FAA’s issuance of EAD 2025-23-53 is a powerful example of the precautionary principle that governs modern aviation safety. Faced with a critical in-flight failure that mirrors a historically significant disaster, the agency chose to act broadly and immediately to mitigate any potential risk across similarly designed aircraft. The grounding of the DC-10 and MD-11 families creates substantial logistical challenges for the cargo industry, but it prioritizes the safety of flight crews and the public above all else. The directive effectively freezes a key segment of the global air freight network until operators can verify the integrity of each aircraft’s engine pylon attachments.
The path forward now depends on two parallel tracks: the meticulous inspections and repairs mandated by the FAA, and the ongoing NTSB investigation into the UPS Flight 2976 incident. The findings of that probe will be crucial in determining whether the pylon failure was an isolated event or indicative of a wider issue related to design, manufacturing, or maintenance procedures. Until then, the industry will watch closely as this “interim action” unfolds, reminding everyone that lessons from the past continue to shape the safety protocols of the present.

NTSB Reports Rising Drug Presence Among Fatally Injured Pilots 2018-2022
NTSB study reveals 52.8% of fatally injured U.S. pilots tested positive for drugs from 2018-2022, highlighting trends in aviation safety.

This article is based on an official press release from the National Transportation Safety Board (NTSB).
NTSB Study Reveals Upward Trend in Drug Presence Among Fatally Injured Pilots
On May 14, 2026, the National Transportation Safety Board (NTSB) released a comprehensive safety research report detailing toxicology results from U.S. civil Incident accidents. The study, titled “2018–2022 Update to Drug Use Trends in Aviation,” analyzed data from 930 pilots who were fatally injured during that five-year period. According to the NTSB press release, the findings highlight a continuing, long-term upward trend in the detection of various medications and substances in aviation accidents.
The most striking statistic from the NTSB’s updated research is that more than half of the fatally injured pilots, 52.8%, tested positive for at least one drug of any type. Furthermore, 27.7% of the pilots tested positive for two or more drugs. While these figures encompass a wide range of substances, including common, non-impairing medications like cholesterol-lowering drugs and cardiovascular prescriptions, the data also points to a rise in the use of potentially impairing substances.
However, the NTSB strongly cautions against jumping to conclusions regarding crash causality. The agency emphasizes that the presence of a drug in post-mortem toxicology testing does not automatically establish that the pilot was impaired while flying, nor does it confirm that the substance contributed to the Accident.
Breaking Down the Toxicology Data
Potentially Impairing and Illicit Substances
While the overall 52.8% figure includes benign medications, the NTSB report isolates data concerning substances that pose a direct risk to aviation safety. According to the study, 28.6% of the fatally injured pilots tested positive for drugs classified as “potentially impairing.” This category encompasses certain prescription medications, controlled substances, illicit drugs, and over-the-counter (OTC) medications.
Notably, the most common potentially impairing substance detected was diphenhydramine. This active ingredient is widely available in over-the-counter allergy and cold medications, such as Benadryl and Unisom. Because it is easily accessible, pilots may underestimate its sedating effects, making it a persistent factor in aviation toxicology reports for over a decade.
In addition to OTC medications, the NTSB noted an increase in the detection of illicit drugs. The study found that 7.4% of the pilots tested positive for illicit substances, a rise driven primarily by the detection of delta-9-THC, the primary psychoactive chemical found in marijuana.
Professionalism and Certification Factors
The General Aviation Divide
The NTSB research highlights a clear demographic and operational divide regarding drug prevalence. The data indicates that drug presence is significantly lower among professional pilots operating under stricter regulatory oversight compared to those in general aviation.
According to the report, pilots conducting Part 135 operations, which include commuter and on-demand flights such as corporate charters and air taxis, exhibited a lower drug presence than pilots operating under Part 91 general aviation rules. Furthermore, pilots holding Airline Transport Pilot (ATP) and Commercial certificates had lower drug detection rates than those holding private, sport, or student certificates, or those flying without any certificate at all.
Medical certification also played a crucial role. The NTSB found that pilots holding an active Federal Aviation Administration (FAA) medical certificate had a lower rate of drug presence than those flying without one, underscoring the effectiveness of routine medical evaluations in the professional aviation sector.
Understanding the Findings: Presence vs. Impairment
AirPro News analysis
When analyzing the NTSB’s findings, we must draw a distinct line between “drug presence” and “active impairment.” Toxicology tests, particularly post-mortem examinations, detect inactive metabolites that can remain in blood or tissue long after a drug’s psychoactive or impairing effects have dissipated. This is especially true for substances like THC and certain long-lasting prescription medications.
The NTSB’s stated purpose for this study is to document trends and provide context for factors that may affect aviation Safety, rather than to assign direct causality to these drugs in specific crashes. However, the persistent presence of diphenhydramine highlights a critical gap in pilot education regarding self-medication.
The FAA maintains strict guidelines regarding over-the-counter medications. Because diphenhydramine has a long half-life and known sedating properties, the FAA advises that pilots must wait at least 60 hours, calculated as five times the drug’s half-life, after their last dose before resuming flying duties. The fact that this specific antihistamine remains the most detected potentially impairing drug suggests that many general aviation pilots are either unaware of the 60-hour rule or are failing to adhere to it.
Historically, the trend is moving in a concerning direction. The NTSB’s previous study covering 1990 to 2012 noted that the proportion of pilots testing positive for at least one drug increased from 10% in 1990 to 40% in 2012. The current leap to 52.8% for the 2018–2022 period indicates that the aviation Manufacturers, particularly the general aviation sector, requires renewed educational campaigns focused on the hidden dangers of common medications.
Frequently Asked Questions (FAQ)
Does a positive drug test mean the pilot caused the crash?
No. The NTSB explicitly states that a positive toxicology result indicates the presence of a drug or its metabolites in the pilot’s system, but it does not necessarily mean the pilot was impaired at the time of the crash or that the drug contributed to the accident.
What was the most common impairing drug found?
According to the NTSB study, the most common potentially impairing drug detected was diphenhydramine, an over-the-counter antihistamine commonly found in allergy and cold medications like Benadryl.
Are airline pilots testing positive at the same rate as private pilots?
No. The study found that professional pilots (those with ATP or Commercial certificates, and those flying Part 135 operations) had significantly lower rates of drug detection compared to general aviation pilots with lower-level certifications.

Chicago Jury Awards $49.5M in Boeing 737 MAX Crash Case
A Chicago jury awarded $49.5 million to the family of a 2019 Ethiopian Airlines crash victim, marking the largest single-death Boeing 737 MAX verdict.

This article summarizes reporting by Reuters. This article summarizes publicly available elements and public remarks.
A federal jury in Chicago has awarded $49.5 million in compensatory damages to the family of a 24-year-old victim of the 2019 Ethiopian Airlines Flight 302 crash. According to reporting by Reuters, the May 13, 2026, verdict represents the largest single-death compensatory award to date stemming from the two catastrophic Boeing 737 MAX disasters that claimed a total of 346 lives in 2018 and 2019.
The trial focused exclusively on determining the appropriate financial compensation owed to the family, as Boeing had previously admitted sole liability for the crash in a 2021 legal stipulation. The victim, Samya Rose Stumo, was a global health worker traveling to Kenya for her first assignment with the public health non-governmental organization ThinkWell. She was also the grand-niece of prominent consumer advocate Ralph Nader.
This landmark decision sets a new financial precedent for the remaining unresolved civil cases against the aerospace manufacturer. We are closely monitoring how this verdict might influence Boeing’s strategy for the final holdout lawsuits, as well as the broader implications for corporate accountability in the Aviation sector.
Breakdown of the $49.5 Million Verdict
Under Illinois wrongful death law, the jury divided the $49.5 million award into three distinct categories to compensate the Stumo family. Based on the provided case details, the largest portion of the award, $21 million, was allocated for Stumo’s pre-death pain and suffering. This specific figure was calculated to account for the passenger’s awareness of impending death and the terror experienced during the flight’s final minutes.
The remaining funds were awarded to compensate the family for their profound emotional toll. The jury allocated $16.5 million for the family’s loss of companionship, alongside an additional $12 million designated for their grief, sorrow, and mental anguish.
Emotional Testimony and Corporate Response
The Stumo family was represented by attorneys Shanin Specter and Elizabeth Crawford of the law firm Kline & Specter. During the trial, emotional testimony highlighted the devastating, long-term impact of the loss on the victim’s relatives.
Michael Stumo, Samya’s father, testified that since her death, the family feels they “don’t have permission to be happy.”
Following the jury’s decision, Boeing issued a statement acknowledging the families’ right to pursue legal action and reiterating their apologies for the tragedies.
“While we have resolved nearly all of these claims through settlements, families are entitled to pursue their claims through the court process,”
A Boeing spokesperson added that the company respects the legal process and remains deeply sorry to all who lost loved ones on both Ethiopian Airlines Flight 302 and Lion Air Flight 610.
Civil Precedents and Ongoing Litigation
This trial marks only the second civil case related to the 737 MAX crashes to reach a jury. According to the source material, the first trial concluded in November 2025, resulting in a $28 million verdict for the family of Shikha Garg, a 32-year-old United Nations consultant killed in the same crash. With the addition of interest and a separate out-of-court settlement for her husband, Boeing ultimately agreed to pay Garg’s family a total of $35.8 million.
To date, Boeing has successfully settled more than 90 percent of the over 150 wrongful death lawsuits out of court. The majority of those settlement figures remain confidential. Currently, fewer than a dozen civil cases remain unresolved, leaving a small but significant number of families still seeking their day in court.
The Push for Punitive Damages
While the trial court previously dismissed the plaintiffs’ claims for punitive damages against Boeing executives and parts manufacturers, the legal battle may not be entirely over. Attorneys for the Stumo family have publicly indicated their intention to appeal the dismissal in an effort to reinstate those punitive claims, which are designed to punish corporate misconduct rather than simply compensate victims.
The Parallel Criminal Track
The civil victories achieved by the families contrast sharply with their ongoing frustration regarding the U.S. Department of Justice’s handling of the criminal investigation into Boeing. In May 2025, the DOJ and Boeing reached a non-prosecution agreement (NPA) to resolve criminal fraud investigations. Under this deal, Boeing agreed to pay $1.1 billion, a sum that included fines, a victim compensation fund, and mandatory investments in safety and compliance programs.
U.S. District Judge Reed O’Connor approved the settlement and dismissed the criminal charges against Boeing in November 2025. However, he notably stated in his ruling that the agreement failed to secure the necessary accountability to ensure the Safety of the flying public.
Families of the victims fiercely opposed the DOJ settlement, arguing it allowed Boeing to evade true criminal accountability. They filed a writ of mandamus to the Fifth Circuit Court of Appeals in an attempt to reopen the criminal case. On March 31, 2026, the appeals court denied the families’ bid, upholding the lower court’s dismissal of the charges.
AirPro News analysis
At AirPro News, we observe that this $49.5 million verdict establishes a significantly higher anchor for the remaining civil cases. By nearly doubling the initial jury award from the November 2025 trial, this outcome may force Boeing to reevaluate its Strategy for the final unresolved lawsuits. The financial risk of taking these remaining cases to trial has demonstrably increased.
Furthermore, the persistent efforts by the victims’ families to appeal for punitive damages and challenge the DOJ’s non-prosecution agreement demonstrate a sustained demand for corporate accountability that extends far beyond compensatory financial payouts. The Aviation Industry will likely feel the reverberations of these legal precedents for years to come, particularly concerning how Manufacturers handle liability, automated system design, and safety disclosures.
Frequently Asked Questions
What caused the Boeing 737 MAX crashes?
Investigations revealed that a flawed automated flight-control system known as MCAS (Maneuvering Characteristics Augmentation System) was implicated in both crashes. Relying on a single faulty angle-of-attack sensor, the system repeatedly forced the planes into uncommanded nosedives that the pilots could not override.
How many people died in the 737 MAX crashes?
A total of 346 people died in two catastrophic disasters: Lion Air Flight 610, which crashed off the coast of Indonesia in October 2018, and Ethiopian Airlines Flight 302, which crashed shortly after takeoff in March 2019.
Has Boeing admitted fault for the crashes?
Yes. In a 2021 legal stipulation, Boeing admitted sole responsibility for the Ethiopian Airlines crash. Consequently, recent civil trials have focused exclusively on determining the amount of financial damages owed to the victims’ families, rather than proving liability.

New Mexico Medical Plane Crash Kills Four in Capitan Mountains
A Beechcraft King Air 90 medical transport crashed near Ruidoso, New Mexico, killing four. FAA and NTSB investigate amid difficult weather and terrain.

This article summarizes reporting by KCRA and Dylan Hyman.
A tragic aviation accident occurred early Thursday morning in New Mexico when a small medical transport plane crashed, resulting in the deaths of all four individuals on board. The incident has prompted a multi-agency emergency response and federal investigations into the cause of the fatal flight.
According to reporting by KCRA and journalist Dylan Hyman, the crash took place in the rugged terrain of the Capitan Mountains outside of Ruidoso. The loss of the aircraft and its crew highlights the inherent risks associated with emergency medical aviation, particularly in challenging environmental conditions.
We are closely monitoring the ongoing recovery efforts, which have been complicated by a resulting wildfire and hazardous weather conditions in the southern New Mexico region.
Incident Details and Flight Path
The aircraft involved in the May 14, 2026, incident was operating as a medical transport flight. Research reports indicate the plane departed from the Roswell Air Center and was en route to the Sierra Blanca Regional Airport when it went down at approximately 4:00 a.m. local time.
All four people aboard the flight were confirmed dead at the scene. Authorities have withheld the names of the victims pending the notification of their next of kin.
“A small medical plane crashed in New Mexico Thursday, killing four people on board, officials said,” according to the initial report by KCRA.
Aircraft Background
The downed aircraft has been identified as a Beechcraft King Air 90, a dual-propeller plane frequently utilized for both medical and corporate transport due to its reliability and cabin size. Secondary reports indicate the specific plane involved in Thursday’s crash was owned by a company named Angel’s Envy.
Emergency Response and Environmental Impact
First responders faced significant logistical challenges upon arriving at the scene. The Capitan Mountains feature difficult, mountainous terrain that complicates both access and recovery operations. Lincoln County Manager Jason Burns publicly confirmed the crash and highlighted the arduous nature of the ongoing recovery efforts.
The impact of the crash ignited a brush fire in the immediate vicinity of the wreckage. As of Thursday morning, a coordinated effort by the U.S. Forest Service and local New Mexico agencies had successfully contained the blaze to an area of less than five acres.
Weather Conditions
Hazardous weather may have played a role in the incident or the rapid spread of the subsequent fire. The Ruidoso area was under an active “red flag” fire risk warning due to hot, dry conditions and low humidity. Furthermore, wind gusts reaching up to 35 mph were reported in the area, creating a volatile environment for both aviation and firefighting efforts.
Federal Investigations and Next Steps
The Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) have launched a joint investigation to determine the exact cause of the crash. The primary factors leading to the accident remain unknown at this time.
Federal investigators are currently evaluating the wreckage. A key focus of the probe will be determining whether the post-crash fire was solely a result of the high-speed impact or if mechanical failures contributed to the tragedy before the aircraft hit the ground.
AirPro News analysis
Air ambulances and medical transport flights inherently operate under high-stakes conditions. Flying at 4:00 a.m. in mountainous terrain with 35 mph wind gusts presents a highly complex operational environment for a small aircraft like the Beechcraft King Air 90. While the exact cause of the crash remains under investigation, the combination of darkness, rugged topography, and severe wind conditions will likely be a focal point for the NTSB.
We anticipate the NTSB’s preliminary report, which is typically released within 30 to 60 days of an aviation accident, will provide crucial insights into the flight’s final moments. This initial documentation should clarify whether weather, mechanical issues, or human factors were the primary drivers of this tragic event.
