AAIB investigation to Tecnam P2008-JC, G-TSFC
Right main landing gear collapsed whilst taxiing, Stapleford Aerodrome, Essex, 22 March 2021.
Summary:
Whilst taxiing after a normal landing, the right main landing gear collapsed due to a failed attachment bolt. Examination of the bolt determined that the failure was due to a fatigue crack, most likely initiated by wear and damage to the bolt’s surface protection.
The operator’s maintenance organisation had recently transitioned the aircraft from a generic maintenance schedule to the maintenance schedule specified by the manufacturer. The new schedule includes a specific check on the condition of these attachment bolts annually or every 100 hours. In addition, the maintenance organisation has stated that it intends to replace these bolts every 200 to 300 hours.
