## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Pilatus Aircraft Ltd. Model PC-12/47E airplanes. 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 seizing of a main landing gear (MLG) spring pack assembly. The FAA is proposing this AD to address the unsafe condition on these products.
