On October 2, 1984, a Piper PA-18 (registration N3952Z) was involved in an aviation accident near Ohio Creek, AK. Investigators recorded the probable cause as: The failure of the right main landing gear wheel adaptor due to torsional tensile overload. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The right main landing gear wheel adaptor failed during the landing roll, causing loss of directional control and an overturn. Examination revealed torsional tensile overload with no signs of fatigue.
During the landing roll, the pilot reported that the right main landing gear wheel adaptor broke. This mechanical failure caused the pilot to lose directional control, and the airplane subsequently overturned.
