During a normal full stall landing, the aircraft veered left and both main landing gear separated. Hardness tests confirmed bolts met tensile strength specifications. A logbook entry noted prior repairs due to porpoising.

Incident Summary

The pilot reported that after flaring the aircraft and executing a normal full stall landing, the aircraft almost immediately veered to the left. Subsequently, both main landing gear separated from the aircraft.

Investigation

Hardness tests were conducted on the left and right main gear attach bolts. The results indicated that all bolts met or exceeded their respective specified minimum tensile strengths.

A review of the aircraft logbook revealed an entry dated August 21, 1983, which noted that repairs had been made to the landing gear. The repairs were reportedly performed because the aircraft had porpoised during a landing sequence.
