Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Raytheon Model DH.125, HS.125, BH.125, and BAe 125 (U-125 and C-29A) series airplanes, and Hawker 800, Hawker 800 (U-125A), Hawker 800XP, and Hawker 1000 airplanes. This proposed AD would require an inspection for cracking or corrosion of the cylinder head lugs of the main landing gear (MLG) actuator and follow-on/corrective actions. This proposed AD is prompted by reports of attachment lugs cracking at the actuator cylinder head. This action is necessary to prevent separation of the cylinder head lugs, which could prevent the MLG from extending and result in a partial gear-up landing. This action is intended to address the identified unsafe condition.
