Airworthiness Directives; Bombardier, Inc., Airplanes Federal Register ↗

Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10, BD-700-1A11, and BD- 700-2A12 airplanes. This proposed AD was prompted by reports that certain seat frames were assembled without applying Loctite in certain locations of concern. This proposed AD would require a modification to the non-locking fastener joints of the seat frame assembly. The FAA is proposing this AD to address the unsafe condition on these products.
