Fatal Crash of a Marine Sea Knight Helicopter on 9 December 1999 Near San Diego

One December 9, 1999, a US Marine CH-46 Sea Knight crashed during a training exercise involving the USNS Pecos. The helicopter had departed from the USS Bonhomme Richard with a crew of 18 for a training exercise at the USNS Pecos.

The helicopter approached the Pecos low and fast, and the left rear wheel of the helicopter had struck and became entangled in the safety netting at the rear of the Pecos. As the pilots attempted to lift off, the helicopter's landing gear remained entangled, causing it to roll to the left and crash into the water.

Eleven of the 18 escaped the helicopter and survived. Seven others were killed in the mishap.

The Marine Corps investigation into the cause of the crash concluded the mishap was caused by human error, stating that the helicopter was flying too low and too fast when it approached the landing pad on the Pecos.
