Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 200 airplanes. This proposed AD was prompted by reports of degraded brake performance during landing due to improperly-sized wear indicating pins. This proposed AD would require determining the lengths of the wear indicating pins of all brake assemblies, shortening the pin if the wear indicating pin is too long, inspecting for normal brake wear, and replacing brakes with new brakes if necessary. We are proposing this AD to detect and correct improperly-sized wear indicating pins, which, if not corrected, could result in worn-out brake pads and subsequent loss of braking power, which could result in runway overruns.
