What to do
Operators must perform inspections and corrective actions as specified in BAE Systems ISB 53-152 Revision 8 starting from the effective date of 2022-03-04. Aircraft previously allowed to operate with a single crack must complete repair or terminating action within 2600 flights of the last inspection or before the next flight if this interval is exceeded. Any detected discrepancies require immediate rectification before further flight.
Summary
Civil Aviation Authority Airworthiness Directive G-2021-0016R1 mandates inspections of the fuselage left-hand nose landing gear well sidewall and retraction jack attachment on all BAe 146 and AVRO 146-RJ aeroplanes, excluding those under the Supplementary Structural Inspection Document programme. This directive addresses cracking found in the retraction jack attachment boss that could compromise structural integrity and crew safety. It requires compliance with BAE Systems ISB 53-152 Revision 8 inspection procedures.
What changed
This revision extends inspection requirements to all BAe 146 and AVRO 146-RJ aircraft, including those modified with torque tightening modification HCM01641A, which were previously excluded. It removes the option to continue operation with a known crack, requiring mandatory repair or terminating action within specified flight cycles. Additionally, a typographical correction was made referencing ISB 53-152 Revision 8 in the terminating action section.
Why it matters
This directive is critical for maintaining the structural integrity of the nose landing gear well sidewall, preventing potential explosive decompression and ensuring flight crew safety. Operators and maintenance organizations must update inspection and repair protocols to comply with the stricter crack management policies. Failure to comply could lead to grounding of aircraft or unsafe flight conditions.
