A Marine Corps MV-22B Osprey erupted in flames on the ground during a joint training exercise in Arizona on Sunday, drawing airport firefighters and prompting an immediate safety response. The tiltrotor aircraft, which combines helicopter-like vertical lift with airplane-like forward flight, suffered a fire in its right nacelle while stationed at Mesa Gateway Airport as part of a larger Air Force-led training event. Crew members executed emergency procedures, shut down the aircraft and evacuated; no injuries were reported.

The aircraft was assigned to Marine Medium Tiltrotor Squadron-266, which operates out of Marine Corps Air Station New River, North Carolina. It was in Arizona to support Exercise Savage Jackal, a training series hosted by Davis-Monthan Air Force Base in Tucson. Marine Corps officials said the blaze originated in the right nacelle, the housing that contains the right engine and associated components. Local airport firefighters responded quickly, deploying foam retardant to suppress the blaze and prevent further damage to the airframe and surrounding facilities.
A video posted by a local pilot showed the right engine housing engulfed in flames and black smoke as emergency responders worked on the scene. The footage captured the rapid arrival of airport fire crews and their use of firefighting foam to knock down the flames. Observers at the airport and the aircrew reported that the evacuation proceeded without injury, and base personnel confirmed that all aboard the aircraft walked away from the incident.
Maj. Joe Leitner, the director of communication strategy and operations for the 2nd Aircraft Wing, confirmed that a mishap investigation is underway. Military investigators have not yet released an estimate of the damage or information about the cost of repairs. Officials emphasized that assessments typically follow an initial on-scene response and that mechanics and crash investigators will inspect the aircraft components to determine the origin and sequence of the malfunction that led to the fire.
The MV-22B Osprey has been both praised for its capabilities and scrutinized for its safety record since entering service. Data compiled over recent decades show the platform has been involved in incidents that resulted in the deaths of 65 service members since 2000. In December 2023, the entire Osprey fleet was grounded following a crash of an Air Force CV-22B off the coast of Japan that killed eight airmen; investigators later traced that accident to a failed left-hand prop rotor gearbox. Earlier mishaps, including a 2022 incident linked to a sprag clutch — the component that helps keep the rotors synchronized — have also figured into broader safety reviews.
The site of Sunday’s fire is in the same general region as some earlier, high-profile Osprey accidents. Roughly 65 miles away from Mesa lies the location of the Marine Corps’ deadliest V-22 accident, a night training crash near Tucson in 2000 that claimed 19 Marines. That earlier mishap was attributed at the time to pilot error during a steep descent, and subsequent inquiries offered additional context and review of the circumstances surrounding the flight. In the wake of each major event, military aviation authorities have conducted technical and procedural reviews aimed at improving safety and reliability across the V-22 community.
Despite the controversies, the Department of Defense continues to rely on the V-22 platform. DoD procurement records show 469 Ospreys have been acquired for use by the Marine Corps, Navy and Air Force, and production of the type is scheduled to continue through fiscal year 2028. MV-22s also participated in high-profile public operations earlier this year, including a large July 4th military flyover in Washington, D.C.; officials confirmed the aircraft involved in Sunday’s incident was not part of that demonstration. For now, the most immediate concerns remain on-site: the aircraft has been secured, firefighting crews have controlled the blaze, and investigators will take apart affected components to determine the cause.
The mishap will be cataloged alongside other incidents involving the V-22 platform and reviewed by the appropriate aviation safety and maintenance authorities. In the short term, investigators will focus on technical inspection of the right nacelle and engine assemblies, interviews with the flight crew and maintenance records, and any available video or telemetry from the airframe. Those findings will ultimately shape recommendations for repair, potential procedural changes and any follow-on safety precautions for similar training operations. For now, the outcome that matters most to officials and fellow service members is clear: the crew evacuated safely and no injuries were reported.

Aviation Safety Network lists the involved aircraft as serial number 168222 and notes it sustained substantial damage from the right engine fire during startup at about 5:55 p.m. local time. The Marine Corps has not issued further updates on the mishap investigation beyond initial statements.
The mishap occurred on July 19, 2026, in the early evening; Mesa Fire & Medical Department units rushed to Phoenix‑Mesa Gateway Airport at about 6:00 p.m. local time and deployed specialized Aircraft Rescue and Firefighting equipment and foam agents to bring the blaze under control.
On July 20, Marine Corps spokesperson 1st Lt. Callin Duffy issued a statement confirming the aircraft involved belonged to the 2nd Marine Aircraft Wing, that the right nacelle caught fire during startup on the ground, and that the incident remains under investigation.
Ryan Smith, director of communications and government relations for the Mesa Gateway Airport Authority, said the aircraft was grounded while emergency teams secured the area.
