The Accident

At approximately 1423(L), on 26 January 2007, a MH-6OS, BUN0 166310 (Bullet 10), assigned to Helicopter Combat Support Squadron TWO THREE Detachment THREE (HSC-23 Det 3), and underway on the USS BONHOMME RICHARD (BHR) (LHD 6), crashed while conducting in-flight operations training in the SOCAL OPAREA. The crash of Bullet 10 resulted in the deaths of four crewmembers:
(1) LT Adam Dyer, Helicopter Aircraft Commander (HAC);
(2) LTJG Laura J. Mankey, Pilot;
(3) AW1 Cory Helman, Search and Rescue (SAR) Aircrew; and,
(4) AW2 (AW/NAC) Christopher M. Will , SAR Aircrew Chief.

At 1342, after refueling and retrieving box lunches, Bullet 10 launched/departed the ship. At 1407, Bullet 10 requested and received permission to climb to 1,000 angels for training. At 1414, Bullet 10 reported "ops normal." At 1423:54, Bullet 10's Electronic Locator Transmitter (ELT) sounded. At 1423:56 a "mayday" call was made. During the mayday call, the HAC is overheard telling the crew to "strap in PCL, PCL." At 1424:03, the ELT stopped transmitting. At 1424, BHR reported the crash and sent Bullet 11 to conduct SAR. At 1435, a SAR swimmer successfully recovered the body from the water. The SAR effort would continue for the next 24 hours involving multiple air and waterborne assets, including all BHR ship assets as well as some Coast Guard assets. At 1505, 27 January 2007, the SAR effort was terminated and three missing crewmembers were declared "Lost at Sea."

On 16 February 2007, during salvage operations, the wreckage of Bullet 10 and the remains of the three missing crewmembers were recovered. Subsequent engineering reports revealed that the damage to Bullet 10 is consistent with the aircraft entering the water in a tail-down, right roll altitude with the aircraft having a backward momentum.

At the time of the incident, the weather satisfied the Visual
Flight Rules (VFR) conditions. Based on review of training records, all crewmembers had the sufficient training, experience and skill to handle in-flight emergencies related to flight control. Moreover, all crewmembers were cleared of all medical conditions or medications which could have caused this mishap.
