NTSB Preliminary Report on Hawker 800XP Crash in Michigan
NTSB investigates Hawker 800XP crash during post-maintenance stall test flight near Michigan, focusing on aircraft behavior and pilot actions.
NTSB Releases Preliminary Findings on Fatal Hawker 800XP Crash in Michigan
On October 16, 2025, a Raytheon Hawker 800XP aircraft crashed near Bath Township, Michigan, resulting in the tragic loss of all three individuals on board. The accident occurred during a critical post-maintenance test flight, a necessary step before the aircraft could be returned to service after an extensive seven-month maintenance period. The National Transportation Safety Board (NTSB) has since launched a full investigation to determine the cause and has released a preliminary report detailing the initial findings. This report provides the first official glimpse into the circumstances surrounding the flight’s final moments.
The significance of this investigation extends beyond this single incident. Post-maintenance flights, particularly those involving complex maneuvers like stall tests, are inherently high-risk operations. The NTSB’s findings will be crucial for understanding the interplay between maintenance procedures, aircraft-specific flight characteristics, and pilot performance under demanding conditions. As we examine the preliminary data, it becomes clear that the focus is on the aircraft’s behavior during a stall and the crew’s actions to recover from it. The NTSB has noted it has investigated at least three other accidents involving required stall tests on business jets, highlighting a pattern of risk that warrants close scrutiny.
This article breaks down the facts as presented in the NTSB’s preliminary report and other public sources. We will explore the background of the flight, the sequence of events leading to the crash, the specific characteristics of the Hawker 800XP’s stall behavior, and the next steps in the ongoing investigation. The information remains preliminary and is subject to change as investigators continue their work, but it provides a foundational understanding of this tragic event.
The Final Flight of XA-JMR
The accident flight was the first time the Raytheon Hawker 800XP, with Mexican registration XA-JMR, had flown since March 2025. The aircraft had been undergoing routine but lengthy maintenance at a Duncan Aviation facility located at Battle Creek Executive Airport (BTL). The work included inspections of the wing leading edges and ice protection systems. Per the manufacturer’s requirements, a successful post-maintenance stall test flight was mandatory before the aircraft could be officially returned to service. The flight crew, who were the primary pilots for the aircraft, opted to conduct the test themselves after being unable to coordinate with a specialized test pilot from a list provided by the maintenance facility.
The flight departed from Battle Creek at 5:08 PM Eastern Standard Time, operating as a general aviation business flight under Part 91 of the Federal Aviation Regulations. The crew requested and received clearance from air traffic control for a block altitude between 14,000 and 16,000 feet to perform their tests. The aircraft leveled off at 15,000 feet and proceeded northeast, passing east of Lansing. According to Automatic Dependent Surveillance-Broadcast (ADS-B) data, everything appeared normal for the first several minutes of the flight.
The situation changed dramatically at approximately 5:27 PM. The aircraft began a rapid descent from an altitude of around 14,000 feet. Air traffic control received an initial, indiscernible transmission, which was immediately followed by a clear but alarming message from the crew. This would be their final communication.
“We’re in a stall, recovering.”
A Rapid Descent and Impact
Following the crew’s last transmission, the aircraft continued its rapid descent. ADS-B data indicates the plane lost a significant amount of altitude in a very short period, with some reports suggesting a descent of over 12,000 feet in less than two minutes. Air traffic controllers made repeated attempts to re-establish contact with the flight crew but received no response. They subsequently alerted other aircraft in the vicinity to be on the lookout for any signs of smoke or wreckage.
The aircraft impacted a wooded area near the intersection of Clark and Peacock roads in Bath Township at approximately 5:28 PM. The wreckage analysis by the NTSB suggests the aircraft struck the terrain in a relatively flat attitude. The impact was not survivable, and a post-impact fire consumed a large portion of the aircraft. All three occupants, the captain, the co-pilot, and a maintenance representative, were fatally injured. First responders and eyewitnesses reported seeing smoke rising from the crash site.
NTSB investigators were on site from October 18 to October 22, meticulously documenting the wreckage and recovering key components for further analysis. All major structures of the aircraft were accounted for at the scene, which is a critical step in ruling out an in-flight structural failure. The investigation’s focus quickly turned to the flight data, the aircraft’s maintenance history, and the specific maneuver being performed at the time of the accident.
The Investigation’s Focus: Stall Characteristics and Crew Performance
The NTSB’s preliminary report places a strong emphasis on the nature of the stall test and the known flight characteristics of the Hawker 800XP. The Pilot’s Operating Manual (POM) for this specific aircraft model contains explicit warnings and procedures for conducting stall tests. These are not routine maneuvers and are performed under a strict set of conditions regarding altitude and weather. The crew’s most recent training occurred at a commercial simulator facility in May 2025, five months before the accident.
A critical detail highlighted in the manual is that the Hawker 800XP provides little to no natural aerodynamic warning, such as a buffet or vibration, before a stall occurs. This lack of physical feedback means pilots must rely entirely on their instruments and training to recognize the onset of a stall. The manual further warns of a phenomenon known as “aileron snatch,” which can affect the aircraft’s roll control during a stall and potentially complicate recovery efforts. These characteristics make stall recovery in the Hawker 800XP a procedure that requires precise and timely inputs from the flight crew.
The investigation will undoubtedly delve into whether the crew followed the prescribed procedures for the stall test and how they responded when the aircraft entered the stall. The recovery of the cockpit voice recorder (CVR) is a pivotal development in this effort. The CVR has been transported to the NTSB’s laboratory in Washington, D.C., for analysis. The audio captured on the CVR will provide investigators with invaluable insight into the crew’s communications, actions, and the overall environment in the cockpit during the flight’s final, critical moments.
Conclusion: Awaiting Answers
The NTSB’s preliminary report on the crash of XA-JMR provides a factual, albeit incomplete, picture of the tragic event. It confirms the flight was a post-maintenance test, that the final communication involved a stall, and that the aircraft model has specific, challenging stall characteristics. These initial findings lay the groundwork for a much deeper investigation into the complex relationship between maintenance, aircraft design, and human factors. The focus now shifts to the detailed analysis of the recovered evidence, particularly the cockpit voice recorder.
As the investigation continues, the aviation community will be watching closely. The final report, which will likely take a year or more to complete, will aim to provide a definitive probable cause and issue safety recommendations to prevent similar accidents. For now, the preliminary findings serve as a stark reminder of the inherent risks associated with test flights and the critical importance of rigorous adherence to procedures, especially when operating aircraft with unique handling characteristics. The answers that emerge will be vital for ensuring the safety of future flights.
FAQ
Question: What was the purpose of the flight that crashed?
Answer: The flight was a required post-maintenance test flight. The aircraft had been in maintenance for seven months, and the manufacturer mandated a stall test be performed before it could return to service.
Question: What is a stall in aviation?
Answer: A stall is an aerodynamic condition where the wing exceeds its critical angle of attack and is no longer able to produce enough lift to support the aircraft’s weight, causing it to lose altitude. Recovery requires specific pilot inputs to reduce the angle of attack and regain lift.
Question: What are the next steps in the NTSB investigation?
Answer: The NTSB will continue to analyze the physical wreckage and, most importantly, the data from the cockpit voice recorder (CVR). This analysis will help them understand the crew’s actions and the sequence of events in the cockpit. A final report with a probable cause will be issued once the investigation is complete.

DAS Aviation Introduces Engine Inlet Fix for Embraer Phenom 300
DAS Aviation and AQRD Engineering develop FAA-approved modification to resolve Embraer Phenom 300 engine inlet fastener issues with minimal downtime.
DAS Aviation, in partnership with AQRD Engineering, has announced a comprehensive new engineering solution designed to resolve recurring engine inlet fastener issues on the Embraer Phenom 300. According to the company’s press release, the modification targets a known vulnerability in the aircraft’s structural components, offering operators a long-term fix rather than a temporary patch.
The Embraer Phenom 300 is widely recognized as one of the most heavily utilized light business jets in the global fleet. Because these aircraft frequently operate in high-cycle environments, such as charter operations and fractional ownership programs, their structural components, particularly engine inlets, endure substantial aerodynamic stress and vibration over their service life.
To address the wear and tear on these specific components, DAS Aviation, a specialized aviation maintenance and repair organization (MRO) and subsidiary of West Star Aviation Holdings, LLC, collaborated with aviation engineering firm AQRD Engineering. Together, they have developed an FAA-approved repair process that goes beyond standard Original Equipment Manufacturer (OEM) manual replacements.
Understanding the Inlet Fastener Issue
Symptoms and Root Causes
During routine maintenance inspections, technicians and operators have increasingly identified degradation in the Phenom 300’s inlet fasteners. The primary symptom, as detailed in the DAS Aviation release, involves blind rivets on the inner barrel of the engine inlet working loose or going missing entirely.
Disassembly and engineering analysis revealed that simply replacing the missing or loose rivets fails to address the underlying problem. The root cause is often hidden damage or wear to the underlying mounting and support flanges. If this underlying degradation is ignored, the fastener failures will recur, potentially leading to more costly maintenance events and safety concerns down the line.
According to the official announcement, the joint engineering effort was developed to provide a permanent fix rather than a band-aid solution, ensuring that hidden failures contributing to loose rivets are fully identified and reworked.
The DAS Aviation and AQRD Engineering Solution
Comprehensive Teardown and Rework
To provide a durable solution, the new modification requires a complete teardown of the affected engine inlet. According to the press release, this allows technicians to perform a 100 percent inspection of the mounting flanges and surrounding structures. Once the hidden damage is addressed, the modification involves the installation of approximately 700 new rivets on the inner barrel, utilizing an engineered fastener solution specifically designed for long-term durability.
DAS Aviation notes that this modification can be applied either reactively, when the issue is discovered during a routine inspection, or proactively by operators wishing to prevent future downtime.
Minimizing Aircraft Downtime
A critical concern for high-cycle operators is Aircraft on Ground (AOG) time. The press release states that the entire inspection, rework, and modification process is structured as a 7-to-10-day event. Because this timeframe closely aligns with the standard downtime required for the aircraft’s routine inspections, operators can seamlessly incorporate the upgrade into their existing maintenance schedules.
To further mitigate operational disruptions, DAS Aviation offers loaner inlets and spare parts, allowing the aircraft to remain in service while its original inlet undergoes the modification process. The company specifies that this upgrade applies to Embraer Phenom 300 inlet part number 505-43420-403, as well as all superseded part numbers.
Industry Impact
AirPro News analysis
We observe that this development highlights a growing trend within the business aviation sector. As popular, workhorse fleets like the Phenom 300 age and accumulate high flight cycles, standard factory maintenance procedures sometimes fall short of addressing long-term structural fatigue. Consequently, third-party MROs and specialized engineering firms are increasingly stepping in to fill the gap.
By developing proprietary, FAA-approved modifications, companies like DAS Aviation and AQRD Engineering are providing operators with alternatives to repetitive, reactive maintenance. For fleet operators, investing in a comprehensive teardown and engineered fix, rather than repeatedly replacing individual rivets, likely represents a significant long-term cost saving and a boost to overall dispatch reliability. We expect to see more collaborative engineering solutions of this nature as other popular light and midsize jet fleets mature.
