## 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 overhaul on a Dornier 328-100 landing gear unit, parts of the MLG (main landing gear) main body and trailing arm bushings have been found corroded. Investigation showed that over time, these bushings can migrate, creating the risk of corrosion in adjacent areas. Such corrosion, if not detected, could cause damage to the MLG, possibly resulting in MLG functional problems or failure.

* * * * *

Functional problems or failure of the MLG could result in the inability of the MLG to extend or retract. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
