Airworthiness Directives; Raytheon Model Hawker 800 and 1000 and Model DH/BH/HS/BAe 125 Series Airplanes (Including Major Variants C29A, U125, and U125A Series Airplanes)

This amendment supersedes an existing airworthiness directive (AD), applicable to certain 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 amendment adds 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 amendment also expands the applicability of the existing AD to include additional airplanes. The actions specified by this 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.
