AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by reports of low clearance in the right wing between the fuel line flexible coupling and the harness support bracket clip-nut, between the fuel line flexible coupling and hydraulic system, and between the hydraulic system and fuel vent tube. This proposed AD would require rectifying the low clearance condition between the fuel line flexible coupling and the harness support bracket clip-nut, rectifying the low clearance condition between the fuel line flexible coupling and the hydraulic system, and doing an inspection for adequate clearance between the hydraulic system and the fuel vent tube and applicable on-conditions actions. The FAA is proposing this AD to address the unsafe condition on these products.
