EASA SIB NM-11-60
Hawker Beechcraft (formerly Raytheon, British Aerospace) BAe125 and Hawker Series aeroplanes — Nose Landing Gear Drag Stay Assembly
Summary
The Special Airworthiness Information Bulletin SAIB: NM-11-60 issued by the FAA addresses an airworthiness concern related to the nose landing gear drag stay assembly on certain Hawker Beechcraft Corporation BAe.125 Series 800A, 800B, 1000A, and 1000B airplanes, as well as Hawker 750, 800, 800XP, 850XP, 900XP, and 1000 models. The bulletin informs operators about issues with slow extension of the nose landing gear and provides guidance for modification to improve performance.
What Changed
This bulletin introduces recommendations for modifying the drag stay assembly of the nose landing gear to increase dimensional tolerances and improve the rigging of the overcenter angle. These changes enhance the extension performance of the nose landing gear, addressing delays reported since 1998. The FAA does not consider this an unsafe condition requiring mandatory Airworthiness Directive action at this time.
Why It Matters
The information is important for aviation professionals because slow extension of the nose landing gear can affect safe landing operations and may lead to abnormal procedures such as gear-up landings. Operators and maintenance organizations need to be aware of the recommended modifications to ensure reliable landing gear operation and maintain aircraft airworthiness. Compliance helps reduce the risk of landing gear extension issues and improves overall flight safety.
What To Do
Owners and operators of the affected Hawker Beechcraft aircraft are advised to comply with the actions outlined in Hawker Beechcraft Service Bulletin SB 32-4068 dated July 2011. While the bulletin is informational and not mandatory, following the service bulletin will help address the drag stay assembly concerns. For further guidance, stakeholders should contact the FAA Aerospace Engineer or Hawker Beechcraft support as provided.
