Mechanical equipment error led to deadly Navy helicopter crash near San Diego

FRESNO, Calif. (KFSN) -- A helicopter crash that claimed the lives of five sailors, including a Central Valley native, was caused by an in-flight mechanical equipment error that led to "severe vibrations" as the aircraft landed aboard the USS Abraham Lincoln, the U.S. Navy said.

An investigation conducted into the crash determined that "an in-flight failure of a damper hose" resulted in the loss of the main rotor damping. As the MH-60S Seahawk touched down on the flight deck, it experienced "severe vibrations" and fell over the side of the aircraft carrier, officials said.

Investigators said the pilot or aircrew were not at fault for the crash.
