The U.S. Marine Corps has concluded its investigation into the crash of a MV-22 from VMM-161 on May 17. Investigators determined that the pilots could have avoided the accident if they had taken steps to minimize or avoid the severe brownout conditions during the landing.

“Repeated, sustained flight time in brownout conditions … while attempting to land caused the left engine to stall, resulting in a loss of power that placed the aircraft in an unavoidable freefall to the ground,” according to a press release.
Two Marines were killed as a result of the crash.
Procedures were changed as a result of the crash, pilots now have only 35 seconds or less to make a “reduced visibility” landing. Previously, it was 60 seconds.
Investigators also called for a new air filtration system to be installed on the Osprey.
