BELL HELICOPTER TEXTRON CANADA 429
The pilot reported that he decided to perform a practice approach to the runway using night vision goggles. He set up the approach and activated the autopilot. About 200 ft above the ground, the helicopter inadvertently entered a fog bank and the pilot lost visual reference to the runway. He attempted to perform a climbing right turn but forgot to deactivate the autopilot. The autopilot initiated a descent into the fog, the pilot maintained a level attitude, and shortly thereafter the helicopter impacted the ground and bounced. The pilot attempted to initiate a climb; however, the helicopter impacted the ground a second time, which resulted in substantial damage to the fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
The pilot’s failure to disengage the autopilot prior to climbing out of a fog bank.
