Learjet Nose-Over After Departing Snow-Covered Runway (N9007S)

Flagstaff, AZ, US

On February 8, 1989, a Piper PA-18 (registration N9007S) operated by Peter Baxter was involved in an aviation accident near Flagstaff, AZ. Investigators recorded the probable cause as: The pilot's failure to maintain directional control while exiting the runway onto snow-covered terrain, which resulted in the aircraft nosing over. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot landing behind a Learjet steered left to exit the runway, lost directional control on snow, and caused the aircraft to nose over without mechanical failure.

What happened

The pilot reported that during the final approach for landing, he observed a Learjet positioned five miles behind him on the same final approach path. He proceeded to execute a normal landing on the runway. Upon completing the touchdown roll, the pilot steered left toward the taxiway side of the runway in an effort to expedite exiting the paved surface.

After reaching the left side of the runway, the pilot was unable to align the aircraft back with the runway heading. Rather than risk ground looping the aircraft, he elected to continue moving off the runway. The aircraft subsequently entered snow-covered terrain and nosed over. No mechanical malfunction or failure was reported prior to the incident.

The investigation

The investigation focused on the operational sequence of events following the landing. Examination of the pilot's account confirmed that the departure from the runway was a deliberate decision made to avoid potential loss of control due to directional alignment issues on the contaminated surface. No evidence of pre-impact mechanical failure was identified.

Findings

Contributing factors included the pilot's inability to maintain proper alignment while exiting the runway and the presence of snow on the shoulder area. The decision to continue off the runway rather than attempt a correction resulted in the nose-over. Directional control loss was the primary factor leading to the damage.

Probable cause

The pilot's failure to maintain directional control while exiting the runway onto snow-covered terrain, which resulted in the aircraft nosing over.
