Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Beech (Raytheon) Model BAe 125-1A through-1000A series airplanes and Model Hawker 800 and 1000 airplanes, that currently requires repetitive inspections to detect fatigue cracking of the sidestay jack pivots of the main landing gear (MLG), and replacement of the sidestay jack pivot assemblies with new assemblies. This action would add a requirement to replace the sidestay jack pivot assemblies with new, improved assemblies; when accomplished, this replacement would terminate the inspection requirements of the AD. This proposal also would expand the applicability of the existing AD to include additional airplanes. The actions specified by this proposed AD are intended to prevent fatigue fracturing of the sidestay jack pivots of the MLG, which could result in the inability of the MLG to deploy and a consequent wheels-up landing.
