1982-10-10: American Aviation AA-1A (N9415L) — Greater Jamestown Area Flying — Jamestown, NY

Jamestown, NY, US

On October 10, 1982, an American Aviation AA-1A (registration N9415L) operated by Greater Jamestown Area Flying was involved in an aviation accident near Jamestown, NY. Investigators recorded the probable cause as: The pilot's improper flare during the landing attempt which caused a bounce, followed by an unsuccessful go-around that resulted in a porpoising motion and subsequent nose gear failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A student pilot practicing touch-and-go landings experienced a bounced landing that led to a porpoising motion, resulting in nose gear failure and engine mount damage.

What happened

The incident occurred while a student pilot was conducting practice touch-and-go landings on runway 13. Environmental conditions included a reported wind from 180 degrees at 15 knots. During one of the landing attempts, the pilot flared too high, causing the aircraft to bounce upon initial contact with the runway.

In response to the bounce, power was applied to initiate a go-around maneuver. However, the aircraft began to porpoise, oscillating vertically as it touched down again. On the third touchdown, the nose gear failed structurally. The force of the impact caused the engine mount to puncture the firewall.

The investigation

The primary mechanical failure identified was the collapse or failure of the nose landing gear. This failure directly resulted in the engine mount penetrating the firewall, indicating a significant structural compromise to the forward fuselage and engine attachment points due to the excessive vertical loads during the porpoising sequence.

Probable cause

The pilot's improper flare during the landing attempt which caused a bounce, followed by an unsuccessful go-around that resulted in a porpoising motion and subsequent nose gear failure.
