Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Cracks have been evidenced on the nose landing gear LH (left- hand) and RH (right-hand) hinge fittings due to stress corrosion on in-service aircraft. If undetected, they could lead to complete rupture of one or two of the fittings.
The unsafe condition is collapse of the nose landing gear. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
