t’s an aircraft with a reputation for falling from the sky. But on at least one occasion, the U.S. military’s controversial V-22 Osprey tiltrotor — a hybrid transport that takes off like a helicopter and cruises like an airplane, thanks to its rotating engine nacelles — did just the opposite. It flew upward, out of control of its pilots.
On March 27, 2006, at a Marine Corps air base in New River, North Carolina, an MV-22 assigned to Medium Tiltrotor Training Squadron 204 experienced an unplanned surge in engine power as the three-man crew was preparing for a flight. “That caused the aircraft to inadvertently lift off the deck approximately 30 feet,” Marine spokesman Maj. Shawn Haney explained. “It came back down … there was major damage sustained to the right wing and the right engine.”
Luckily, the three crewmembers were unhurt. The cost to repair the self-flying Osprey totaled $7,068,028, according to the Naval Safety Center, which tracks all Navy and Marine aircraft mishaps. An investigation by the Navy and manufacturers Bell and Boeing resulted in tweaks to the V-22’s engine controls.
Yet the Marines and the Naval Safety Center ultimately decided that the Osprey’s dangerous joyride didn’t count as a serious flying accident, known in Pentagon parlance as a “Class A flight mishap.” The reason, said Capt. Brian Block, a Marine spokesman: The aircraft wasn’t supposed to take off just then; therefore, it’s not a flight problem. If a V-22 suffers damage while preparing to launch or after landing, or if the crew does not explicitly command the aircraft to take off but it does anyways, then the accident doesn’t count as a flight accident.
