Summary
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports of multiple in-flight departures of the aft belly fairing access panels. This proposed AD would require modification of the aft belly fairing access panels. We are proposing this AD to address the unsafe condition on these products.
