Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models 58 and G58 airplanes. This proposed AD was prompted by installation of oversized clamps on fuel vapor return and/or fuel vent lines in the outboard sections of the left and right wings. This proposed AD would require inspecting for oversized or deformed fuel hose clamps and replacing as necessary. We are proposing this AD to correct the unsafe condition on these products.
