Airworthiness Directive · Amendment 39-10068 · 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 numbers (S/N) 1 through 12 inclusive, 14 through 112 inclusive, 114 through 148 inclusive, 322, and 323; on which main landing gear cylinder attach fitting assemblies having part number (P/N) 159WM10276-1 and -2 and balls having P/N 159WM10277-1 are not installed; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Gulfstream Model G-159 (G-I) airplanes, that currently requires modification and repetitive inspections for cracks in the main landing gear (MLG) retract cylinder attachment fittings. This amendment requires installation of improved attachment fittings which, when accomplished, terminates the requirement for the repetitive inspections. This amendment is prompted by the development of a modification that positively addresses the identified unsafe condition. The actions specified by this AD are intended to prevent failure of the MLG retract cylinder attachment fitting due to fatigue cracking. This condition, if not corrected, 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.
