Airworthiness Directive · Amendment 39-10066 · Gulfstream Aerospace Corporation Model G-159 (G-I) Airplanes
Gulfstream Aerospace Corporation Model G-159 (G-I) Airplanes
Model G-159 (G-I) airplanes; serial number (S/N) 1 through 12 inclusive, 14 through 83 inclusive, and 114; on which main landing gear (MLG) uplock beam support brackets (angles) having part numbers (P/N) 159W10150-71 and -72 are not installed; confiscated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Gulfstream Model G-159 (G-I) airplanes, that currently requires repetitive inspections to detect cracks and loose rivets in the forward brackets for the main landing gear (MLG) uplock beam assembly, and replacement of the brackets, if necessary. This amendment requires installation of redesigned brackets that preclude the potential for cracking and loose rivets, when accomplished, this installation constitutes terminating action for the currently required inspections. This amendment is prompted by the development of an installation that will positively address the identified unsafe condition. The actions specified by this AD are intended to prevent failure of the bracket for the MLG uplock beam assembly due to cracking and loose rivets; such failure could result in the inability to retract the MLG.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
