Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Inc. Model BD-100-1A10 airplanes. This proposed AD was prompted by a determination that a revised restrictive airworthiness limitation is necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate a revised restrictive airworthiness limitation for the aft engine mount attachment bolts. The FAA is proposing this AD to address the unsafe condition on these products.
