condition on an aviation product. The MeAl describes the unsafe condition as:

Two cases of complete nose landing gear (NLG) shock absorber bolts

failure were reported to the manufacturer. In both cases, the crew was

unable to retract the gear and was forced to an In Flight Turn Back. In one

case, the aircraft experienced a low speed runway excursion. The root

cause of the bolts failure has been identified being due to a boh(s) overtorque. The investigation has highlighted that the desi!,'l1 of the NLG shock

absorber was not tolerant to the over-torque, and an inspection plan has

been developed to trnck any N LG shock abhorber-lo-main barrel
