## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd Model PC-24 airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the vinyl grommets on the upper panel assembly on the left-hand (LH) and right-hand (RH) emergency exits becoming rigid after exposure to low temperatures, which could result in failure of the emergency exits to open during an evacuation. This proposed AD would require replacing the grommets. The FAA is proposing this AD to address the unsafe condition on these products.
