Nose gear failure during forced landing after engine power loss (N80241)

Mulino, OR, US

On April 8, 1985, a Cessna 172M (registration N80241) was involved in an aviation accident near Mulino, OR. Investigators recorded the probable cause as: The separation of the throttle cable housing from its clamp on the rear of the engine mount, which caused a loss of engine power during final approach. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot lost engine power on final approach due to a separated throttle cable housing, resulting in a forced landing where the nose gear sheared off and the aircraft nosed over.

What happened

During the final approach phase of flight, the pilot advanced the throttle lever to increase engine power. Immediately following this action, the engine ceased operating. Unable to maintain altitude or airspeed, the pilot executed a forced landing onto an adjacent cabbage patch. Upon impact, the nose landing gear sheared off, causing the aircraft to pitch forward and nosed over.

The investigation

Post-accident examination of the aircraft revealed that the throttle cable housing had separated from its mounting point. Specifically, the failure occurred in the area where the housing is clamped to the rear of the engine mount. This mechanical separation prevented the transmission of throttle input to the engine, leading to the loss of power.

Findings

The investigation determined that the throttle cable housing failed at the clamp attachment point on the rear of the engine mount. This failure resulted in a complete loss of engine power during a critical phase of flight. The subsequent forced landing resulted in substantial damage to the nose gear and airframe.

Safety message

Regular inspection of throttle control linkages and cable clamping mechanisms is essential to prevent separation failures that can lead to sudden power loss.

Probable cause

The separation of the throttle cable housing from its clamp on the rear of the engine mount, which caused a loss of engine power during final approach.
