Narrative:
AAIB investigation to Tecnam P2008-JC, G-TSFC: Right main landing gear collapsed whilst taxiing, Stapleford Aerodrome, Abridge, Essex, England, 22 March 2021. The incident was the subject of an AAIB Investigation, and the following is taken from the AAIB report, published on 9 June 2022:

"Synopsis
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.

AAIB Investigation
After a normal landing the right main landing gear collapsed as the aircraft taxied clear of the runway. Examination identified that the bolt securing the inboard end of the landing gear leg had failed in fatigue. Wear and damage to the surface protection was likely to be the initiation of the fatigue crack. The wear indicated that the bolt had been moving in its bushings

The aircraft had been maintained using the LAMP (Light Aircraft Maintenance Programme). LAMP was a generic programme applicable to all light aircraft and it did not specifically require a detailed inspection of these bolts. The LAMP is being phased out in favour of Self Declared Maintenance Programmes. Shortly before the accident, the aircraft had been transitioned to the maintenance schedule specified by the aircraft manufacturer. This schedule includes the following specific inspection to determine the condition of these
attachment bolts:

‘Annually or every 100 hours;
Inspect nose and main gear attachments, bolts and bushings for condition and security. Check especially for cracks, corrosion, and damaged surface protection. Inspect for looseness, condition and security of mounting points.’

The operator’s maintenance organisation has stated that, additionally, they will check the torque of the bolts every 50 hours and intend to replace them every 200 to 300 hours. These changes should allow any degradation of these attachment bolts to be identified before failure and therefore prevent recurrence".

Nature of Damage to airframe
Per the AAIB report "Right main landing gear collapsed". Presumably repaired and returned to service, as still flying in December 2024. Total amount of flying hours accumulated on the airframe: 1,874 as at 18 March 2024.
