NTSB Releases Preliminary Report on Montana Robinson R66 Helicopter Crash
NTSB issues initial findings on fatal Montana Robinson R66 helicopter crash, detailing flight events and ongoing investigations.
NTSB Releases Initial Findings on Fatal Montana Helicopters Crash
The National Transportation Safety Board (NTSB) has issued its preliminary report concerning the fatal crash of a Robinson R66 helicopter on October 22, 2025, near Ekalaka, Montana. The accident, which occurred under dusk conditions, tragically claimed the lives of the pilot and three passengers. This initial document lays out the foundational facts gathered by investigators at the scene and through early interviews, serving as the first step in a long and meticulous process to determine the cause. It is a stark and factual account of the flight’s final moments, the condition of the aircraft, and the circumstances surrounding the event.
Preliminary reports are a standard and crucial part of any aviation accident investigation. Their purpose is not to assign blame or pinpoint a definitive cause but to establish a public, factual record of what is known so far. This information allows the aviation community and the public to understand the basic sequence of events while the NTSB, in collaboration with parties like the Federal Aviation Administration (FAA) and the aircraft manufacturer, delves deeper into the mechanical, operational, and human factors involved. The details within this report on the Montana crash, while not conclusive, provide critical direction for the ongoing investigation.
The flight in question, operating under personal use regulations, was not an isolated journey. The Robinson R66 was flying in tandem with a Cessna 182, having departed from a private ranch. This two-aircraft formation adds a unique dimension to the investigation, providing a direct aerial witness to the helicopter’s flight path just before the accident. The coordination between the two pilots and the subsequent loss of contact are key elements outlined in the NTSB’s initial summary, setting the stage for a complex analysis of the moments leading up to the tragic event.
Unpacking the Preliminary Findings
The Final Moments of Flight N67GA
According to the NTSB’s report, the accident flight began at approximately 18:18 mountain daylight time. The pilot of the Robinson R66, registration N67GA, communicated an intention to fly over the scenic Chalk Buttes on the way to Ekalaka Airport (97M). The pilot of the accompanying Cessna 182 observed the helicopter maneuvering through a gap in the rock formations. Shortly after, the helicopter fell back, and the Cessna pilot lost visual sight of it. This was the last time the aircraft was seen intact by the accompanying pilot.
The timeline of events becomes critical in the minute that followed. After losing visual contact, the Cessna pilot noted that the helicopter also disappeared from the aircraft’s Automatic Dependent Surveillance–Broadcast (ADS-B) display, a system that tracks aircraft positions. Repeated attempts to establish radio communication with the helicopter pilot were unsuccessful. This sudden and complete loss of all forms of contact signaled a serious and immediate problem, prompting the sequence of events that would ultimately lead to the discovery of the wreckage.
A crucial piece of information in the preliminary report comes from a ground-based witness located approximately three-quarters of a mile from the accident site. The witness reported hearing both the helicopter and the airplane overhead. They observed the R66 flying low over the Buttes before it began to gain altitude. It was at this moment that the witness saw something separate from the helicopter. Immediately after, the aircraft descended out of the witness’s line of sight. This testimony provides a significant focal point for investigators as they analyze the wreckage for evidence of an in-flight structural failure or departure of a component.
A witness, located about 3/4 of a mile from the accident site, reported hearing the helicopter and airplane overhead. She observed the helicopter flying low over the Buttes, then begin to gain altitude. At this point, she saw something come off the helicopter, after which it descended out of her line of sight.
The Scene of the Accident
The helicopter wreckage was located in an open field next to a wooded area within the Chalk Buttes, at an elevation of 3,779 feet. The NTSB report describes the aircraft as substantially damaged upon impact. The distribution of debris is a critical element for investigators, as it helps reconstruct the accident sequence. A scattered debris field can indicate an in-flight breakup, while a more contained site might suggest an impact with structural integrity largely intact.
The wreckage debris area was measured to be approximately 300 feet wide by 300 feet long. This dimension is significant and will be carefully mapped and analyzed. The report specifies that fragments found within this area included Plexiglass, aircraft doors, the tail rotor driveshaft cover, stabilizers, the tail rotor itself, and the pilot’s side GPS mount. The identification of these specific parts, particularly flight control and structural components, will be central to determining what object the witness may have seen separating from the aircraft.
The aircraft involved was a Robinson Helicopter Co. R66 model with registration N67GA. While this was a personal flight conducted under Title 14 Code of Federal Regulations Part 91, the helicopter held operating certificates for rotorcraft external load operations and agricultural aircraft applications. This information provides background on the aircraft’s certified capabilities but does not imply it was engaged in such activities at the time of the accident. The investigation will include a thorough review of the aircraft’s maintenance records and history.
The Investigation and Surrounding Conditions
The Path Forward for the Investigation
The NTSB has taken the lead on this investigation, with Joshua Cawthra serving as the Investigator in Charge. In line with standard procedure for major aviation accidents, the NTSB is working with several other organizations. These include the FAA, which oversees civil aviation safety; Rolls Royce, the manufacturer of the R66’s engine; and the Robinson Helicopter Company, the manufacturer of the airframe. This collaborative approach ensures that expertise from all relevant fields is brought to bear on the analysis of the accident.
It is important to reiterate that this report is only the first step. The information is preliminary and subject to change as more evidence is collected and analyzed. The next phases of the investigation will involve a detailed examination of the recovered wreckage, a forensic analysis of the engine and flight control systems, and a review of the pilot’s records, training, and medical history. The witness account of a separating object will undoubtedly lead to a focused inspection of the airframe’s structural integrity and all major components.
The report also provides important context regarding the environmental conditions at the time of the crash. The flight was operating in Visual Meteorological Conditions (VMC), with clear skies and 10 miles of visibility. The accident occurred at dusk, a time of changing light that can present challenges for pilots. However, the initial data does not suggest that adverse weather was a contributing factor. No flight plan was filed for the personal flight, which is not unusual for operations conducted under VMC.
Awaiting a Final Determination
The preliminary report on the crash of N67GA provides a factual but somber outline of a tragic event. It confirms the date, location, and devastating loss of four lives. Key takeaways from this initial phase include the tandem flight with a Cessna 182, the sudden loss of electronic and radio contact, and the powerful eyewitness testimony of an object separating from the helicopter just before the crash. The documented debris field, containing pieces of the cabin and tail assembly, gives investigators a clear path for further forensic examination.
As the NTSB and its partners continue their work, the aviation community awaits a final report that will provide a probable cause. This process is methodical and can take a year or more to complete. The ultimate goal is not only to understand what happened on October 22 but to identify safety lessons and issue recommendations that can help prevent similar accidents in the future. For now, the preliminary findings serve as a critical, fact-based foundation for the comprehensive investigation that lies ahead.

FAA Awards L3Harris Contract to Modernize US Airspace Through 2045
The FAA awarded L3Harris a contract to upgrade 700+ ground stations and operate the US aircraft tracking network through 2045.
On July 1, 2026, the Federal Aviation Administration (FAA) awarded L3Harris Technologies a contract to upgrade and operate the United States aircraft tracking network through 2045. The modernization effort will overhaul ground infrastructure to support the integration of advanced air mobility (AAM) vehicles and drones into the National Airspace System.
In a press release issued on July 1, 2026, L3Harris announced the agreement, which mandates the upgrade of at least 700 ground stations across the country. The enhanced network will provide real-time, satellite-based flight positioning data while bolstering cybersecurity measures to protect air traffic management systems. The exact monetary value of the contract was not disclosed.
Expanding surveillance for next-generation airspace
The contract extends the role of L3Harris in managing the FAA surveillance infrastructure for nearly two more decades. The upgraded ground stations are designed to handle increased network capacity, a requirement as the airspace becomes more crowded with non-traditional aircraft.
Kathy Crandall, President of Mission Networks, Space & Mission Systems at L3Harris, emphasized the operational impact of the upgrades.
“L3Harris is propelling the FAA’s modernization vision forward by delivering an advanced surveillance infrastructure that will define the future of our airspace system and ensure increased safety for all air travelers.”
Crandall added that expanding network capacity ensures the United States maintains its position in global air traffic management.
Alignment with broader FAA modernization initiatives
This surveillance contract aligns with ongoing FAA efforts to replace aging infrastructure across the National Airspace System. The agency has been executing its Facility Replacement and Radar Modernization (FRRM) strategy, which targets the replacement of over 370 air traffic control facilities and 618 radars that average 36 years of age.
L3Harris is already involved in parallel infrastructure projects for the FAA. The company is currently executing the FAA Telecommunications Infrastructure (FTI) upgrade. That project replaces legacy copper wire connections with high-speed fiber optic networks across FAA facilities, providing the bandwidth necessary to support emerging aviation technologies like electric aviation vertical takeoff and landing (eVTOL) aircraft and uncrewed aerial systems.
AirPro News analysis
The extension of the L3Harris mandate through 2045 highlights the reliance of the FAA on established defense and aerospace contractors to execute its long-term modernization goals. As the National Airspace System transitions to accommodate AAM and widespread drone operations, the data bandwidth and latency requirements for air traffic control will increase exponentially. We view the concurrent execution of the surveillance network upgrade and the FTI fiber optic rollout as a necessary synchronization. Without high-speed ground data transmission, the benefits of satellite-based, real-time tracking for low-altitude and autonomous aircraft would be severely bottlenecked.

FAA Proposes Supersonic Noise Standard to Repeal 1970s Ban
The FAA announced noise-based certification standards for supersonic overland flight on June 30, 2026, targeting final rules by mid-2027.
The Federal Aviation Administration (FAA) has proposed a new noise-based certification standard for supersonic aircraft, initiating the formal regulatory process to repeal the 1970s ban on commercial supersonic flight over United States territory.
Announced on June 30, 2026, by U.S. Transportation Secretary Sean P. Duffy and FAA Administrator Bryan Bedford, the rulemaking aims to establish acceptable noise thresholds for overland flights. The proposal provides aerospace Manufacturers with the regulatory framework required to finalize next-generation supersonic designs that utilize quiet boom and “Mach cutoff” technologies.
Regulatory framework and timeline
The initial proposal focuses on noise-based certification standards during cruise flight. According to the FAA press release, the agency plans to introduce a second rule covering landing and takeoff noise standards later in 2026. The FAA has set a target date of mid-2027 to finalize both sets of rules.
U.S. Transportation Secretary Sean P. Duffy characterized the initiative as a move to safely enable the next quantum leap in aviation technology. FAA Administrator Bryan Bedford noted that advances in aerospace engineering, materials science, and noise reduction will eliminate the traditional sonic boom.
“This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports,” Bedford stated.
The White House Office of Science and Technology Policy (OSTP) is also involved in the initiative. OSTP Director Michael Kratsios stated that the updated rules will strengthen the industrial base and ensure the future of aviation is built in America.
Technological foundations and industry response
The June 30 announcement follows a series of preparatory steps by both regulators and the aerospace industry. On January 27, 2026, the FAA unveiled a new agency structure that included the creation of the Office of Advanced Aviation Technologies, a division specifically tasked with overseeing the integration of supersonic aircraft into U.S. airspace.
The technical basis for the new noise thresholds draws on data from the NASA and Lockheed Martin X-59 quiet supersonic research aircraft. The X-59 completed its First-Flight on October 28, 2025. The aircraft was explicitly designed to reduce sonic booms to a gentle thump, providing regulators with the acoustic data necessary to establish new overland flight standards.
Commercial developers have responded positively to the regulatory clarity. Boom Supersonic CEO Blake Scholl confirmed that the FAA rulemaking includes provisions for the “Boomless Cruise” or Mach cutoff approach. Boom has been demonstrating this operational concept with its Boom XB-1 test aircraft. Scholl described the FAA announcement as a major step toward the supersonic renaissance.
AirPro News analysis
We view the establishment of a definitive noise standard as the single most significant regulatory hurdle for the revival of commercial supersonic travel. For the past several years, manufacturers have been developing quiet supersonic technologies without a finalized target for acceptable noise levels. By defining the Certification standards, the FAA is shifting the primary challenge for companies like Boom Supersonic from regulatory uncertainty to engineering execution. The mid-2027 target for finalizing both cruise and terminal area noise rules sets a tight timeline, but it aligns with the development schedules of the next-generation supersonic aircraft currently in testing.

Pilatus PC-6 Crash in France Kills 11 on Skydiving Flight
A Pilatus PC-6 crashed near Nancy-Essey aerodrome on June 28, 2026, killing all 11 aboard in France’s deadliest skydiving accident in 30 years.
This is a developing story. Information may change as official details are released.
This article summarizes reporting by the Associated Press, Reuters, and CBS News, alongside official statements from the Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA).
Eleven people sustained fatal injuries on June 28, 2026, when a Pilatus PC-6/B2-H4 Turbo Porter Commercial-Aircraft crashed shortly after takeoff during a skydiving flight in northeastern France.
The Accident occurred at approximately 09:00 UTC (11:00 local time) near the Nancy-Essey aerodrome (ENC/LFSN). According to French Transport Minister Philippe Tabarot, the event represents the deadliest general aviation accident involving skydiving operations in France in approximately 30 years. The Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA) has deployed four Investigations to the site to determine the circumstances of the crash.
Aircraft departure and impact
The aircraft, registered in Germany as D-FIPS and reportedly owned by Classic Wings GmbH, departed Nancy-Essey for a tandem skydiving excursion. Less than one minute after takeoff, the aircraft banked left and descended almost vertically, impacting a grassy area in the town of Tomblaine, approximately 300 meters from the runway.
The Meurthe-et-Moselle Prefecture confirmed that all 11 occupants died in the crash. The victims included one pilot, five skydiving instructors, and five students. Thierry Pechey, president of the Meurthe-et-Moselle branch of the Order of Independent Nurses, told CBS News that the students were local nursing colleagues participating in a first-time jump.
Local officials noted the aircraft crashed near a residential neighborhood and shopping center. Yves Séguy, Prefect of the Meurthe-et-Moselle department, told the Associated Press that the accident could have caused collateral casualties had the impact occurred just a few dozen meters away. No injuries on the ground were reported.
Safety investigation and witness reports
The BEA is leading the Safety investigation, working in coordination with the Paris Criminal Investigation Department and the Air Transport Gendarmerie Brigade (GTA). The official cause of the accident remains under investigation.
While the BEA has not confirmed any mechanical faults, Reuters reported that witnesses on the ground heard the aircraft engine noise stop suddenly before the descent. Hervé Féron, the mayor of Tomblaine, stated that the aircraft fell in an unexplained manner during its initial ascent.
French Interior Minister Laurent Nunez noted that families of the victims were present at the aerodrome and witnessed the accident, resulting in significant psychological trauma.
AirPro News analysis
We note that this accident follows another fatal skydiving flight earlier in June 2026 in Missouri, which resulted in 12 fatalities. While the two events involve different operators, aircraft types, and regulatory jurisdictions, the proximity of these high-fatality accidents will likely bring renewed regulatory scrutiny to general aviation skydiving operations globally. The Pilatus PC-6 involved in the Tomblaine accident was 35 years old, a common age for utility turboprops in the skydiving sector, where aircraft are subjected to high-cycle operations characterized by rapid ascents and descents. The BEA preliminary report will be critical in establishing the sequence of events following takeoff.
