Rotorway 162FS/N: 6174

Summary

On May 24, 2008, a Rotorway 162F (N771SS) was involved in an accident near Gonzales, TX. The accident resulted in 1 serious injury, 1 minor injury. The aircraft was destroyed.

The National Transportation Safety Board determined the probable cause of this accident to be: Failure of the main rotor drive belt for undetermined reasons.

The private pilot and his passenger had just departed in a single-engine experimental helicopter when he heard a "loud pop" followed by a loss of engine power. The pilot entered an autorotation from an altitude of 75 feet and flared at approximately 40 feet above the ground to avoid hitting trees. The helicopter landed hard in a grass field and the skids were spread upon impact. The two occupants were able to deplane before the engine exhaust caught the surrounding grass on fire, and subsequently destroyed the helicopter. The pilot reported that the main drive belt, which he had been recently replaced, had failed. The helicopter wreckage was examined by an FAA inspector; however, the drive belt could not be located and it was assumed to have been destroyed in the post-impact fire.

This accident is documented in NTSB report DFW08CA152. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N771SS.
