On March 19, 1987, a Bell 206B (registration N666TV) operated by Omni Flight,inc. was involved in an aviation accident near Austin, TX. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 8 related events involving the same aircraft type or operator are linked below.
A helicopter was damaged during a hard landing on a rooftop heliport following a partial power loss caused by an uncommanded engine deceleration. The pilot stretched the glide to land on the pad, but main rotor RPM decay led to a hard impact. Engine examination did not reveal the cause of the power loss.
Incident Sequence
During an approach to a rooftop heliport, a helicopter experienced a partial power loss due to an uncommanded engine deceleration. The aircraft was approximately 40 feet above and 40 feet horizontally from the heliport pad when the power loss occurred. The pilot responded by stretching the glide path to reach the landing pad. However, the main rotor RPM decayed, resulting in a hard landing that caused damage to the helicopter.
Investigation
Following the incident, the engine was examined and subjected to functional testing. The investigation did not reveal the cause of the uncommanded engine deceleration or the resulting partial power loss. The hard landing was attributed to the decayed main rotor RPM, which was a consequence of the power loss.
