On June 22, 1990, a Cessna 185-A (registration N4145Y) was involved in an aviation accident near Anchorage, AK. Investigators recorded the probable cause as: The fracture of the right main landing gear torque plate, which led to a loss of directional control during landing. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft veered right upon landing at Merrill Field, resulting in a nose-over. Investigation revealed the right main gear torque plate had fractured.
What happened
Upon landing at Merrill Field Airport, the airplane began to veer sharply to the right. The pilot attempted to maintain control but was unable to correct the ground track. As a result of this loss of directional control, the aircraft nosed over on the runway surface.
The investigation
A physical examination of the wreckage was conducted to determine the mechanical cause of the incident. Inspectors discovered that the right main landing gear torque plate had separated into two pieces. A portion of this broken torque plate was found lying on the runway, confirming the structural failure.
Probable cause
The fracture of the right main landing gear torque plate, which led to a loss of directional control during landing.
