## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Daher Aerospace (type certificate previously held by SOCATA) Model TBM 700 airplanes. This proposed AD was prompted by 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 non-conforming dump switch ejecting from its slot. This proposed AD would require modifying certain dump switches. The FAA is proposing this AD to address the unsafe condition on these products.
