Helicopter Accident During Simulated Engine Failure in Practical Test (N7058T)

Council Bluffs, IA, US

On August 31, 1997, a Hughes 269A (registration N7058T) was involved in an aviation accident near Council Bluffs, IA. Investigators recorded the probable cause as: inadequate supervision by the designated examiner by failing to ensure a timely autorotation recovery was initiated. A related factor was: the student pilot allowed the rotor rpm to diminish after the examiner simulated a loss of engine power. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A helicopter conducting a simulated engine failure maneuver during a Commercial Rotorcraft-Helicopter practical test impacted terrain, came to rest on its left side. The DPE stated he failed to recover.

Accident Details

A Designated Pilot Examiner (DPE) was administering a Commercial, Rotorcraft-Helicopter Practical Test to an applicant. According to the DPE, he instructed the student to perform a simulated engine failure from 450 feet above ground level (agl) over runway 13. The DPE initiated the maneuver by reducing the throttle to idle. The student did not respond, and the rotor RPM decreased. After assessing the situation, the DPE took control of the helicopter. He attempted to recover by decreasing the collective to the full down position, increasing the throttle, and applying slight forward cyclic. However, the DPE was unable to recover, and the helicopter impacted in a slight nose low attitude, then bounced and came to rest on its left side.

Witness Account

A witness reported seeing the helicopter at 50 to 75 feet above the ground before its forward speed stopped and it entered a steep, spiral descent. After reaching the accident site, the witness heard the student ask the DPE what had happened and if something had failed. The DPE responded, "No...it was me, I failed."
