## 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:

During inspection of undercarriage main beam sidestays, bolts attaching the undercarriage main beam sidestay to frame 29 were found with the heads of the bolts sheared off. Loose bolt assemblies were also found. If sheared or loose bolts are not detected and replaced, a possible consequence is the collapse of the main landing gear. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
