On September 4, 2022, at 0808 Pacific daylight time, a Bell 407 helicopter, N687AM, was substantially damaged when it was involved in an accident near Mount Baldy, California. The pilot was seriously injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 91 flight.

The helicopter was being used to shuttle water and equipment in support of a local charity event. The pilot had completed four shuttle flights and was approaching the main, off-airport landing zone to land when the low rotor RPM (revolutions per minute) warning sounded. He aborted the approach and attempted to increase power. The engine power did not recover, and the pilot performed an autorotation to a nearby road. The helicopter rolled upon landing, which resulted in substantial damage.

The helicopter was retained for examination.
