Navy investigators concluded that the Aug. 31 helicopter crash that resulted in the death of five sailors was caused by a mechanical error.

The Navy concluded its investigation into the MH-60S Seahawk that fell into the Pacific Ocean while trying to land aboard the USS Abraham Lincoln on April 18 and released its findings on Tuesday.

A redacted copy of the report shows that investigators found “no evidence that weather conditions or pilot error were causal or contributing factors to the mishap” based on interviews with witnesses.

Instead, the accident was “caused by the failure of the yellow damper hose on LT 616 in-flight, resulting in total loss of main rotor system damping and the immediate onset of severe vibrations upon touchdown,” the report read.

The sailors who died were: Lt. Bradley A. Foster, 29, a pilot from Oakhurst, California; Lt. Paul R. Fridley, 28, a pilot from Annandale, Virginia; Naval Air Crewman 2nd Class James P. Buriak, 31, from Salem, Virginia; Hospital Corpsman 2nd Class Sarah F. Burns, 31, from Severna Park, Maryland; and Hospital Corpsman 3rd Class Bailey J. Tucker, 21, from St. Louis.
