## Summary

We are revising an earlier NPRM 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:

* * * a Nose Landing Gear (NLG) hinge pin rupture that causes an uncommanded NLG retraction. Investigations identified the unsafe condition resulting from an incomplete thermal treatment done on three hinge pin batches lowering their mechanical properties with a high risk of deformation under service loads.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
