Summary
This document proposes the supersedure of an existing airworthiness directive (AD); applicable to certain Raytheon Model DH.125, HS.125, BH.125, and BAe.125 (U-125 and C-29A) series airplanes; and Model Hawker 800, Hawker 800 (U-125A), Hawker 800XP, and Hawker 1000 airplanes; that currently requires an inspection for cracking or corrosion of the cylinder head lugs of the main landing gear (MLG) actuator and follow-on/corrective actions. This action proposes to expand the applicability of the existing AD to add an airplane model and further clarify the applicability; and, for certain airplanes, to clarify the compliance time of the inspection requirements. The actions specified by the proposed AD are intended to prevent separation of the cylinder head lugs, which could prevent the MLG from extending and result in a partial gear-up landing.
