What to do
Operators of Boeing 787-8 airplanes must perform repetitive surface HFEC inspections of the left and right main landing gear aft hanger link lug fittings as specified in Boeing Alert Requirements Bulletin B787-81205-SB530070-00 RB, Issue 001, dated August 31, 2018. Any detected cracks must be repaired using FAA-approved methods. The directive is effective January 13, 2020, and compliance must be achieved within the times specified in the service bulletin.
Summary
Airworthiness Directive 2019-22-09 is a final rule issued by the Federal Aviation Administration (FAA) addressing certain Boeing 787-8 airplanes. It mandates repetitive inspections of the main landing gear aft hanger link lug fittings for fatigue cracking using high frequency eddy current (HFEC) techniques. The directive aims to ensure the structural integrity of the affected aircraft by detecting and repairing cracks in these critical components.
What changed
This new airworthiness directive introduces mandatory repetitive HFEC inspections of the left and right main landing gear aft hanger link lug fittings on Boeing 787-8 airplanes. It requires operators to perform inspections at specified intervals and carry out necessary repairs if cracks are found. The AD also provides procedures for alternative methods of compliance and repair approvals.
Why it matters
This directive is crucial for aviation professionals because fatigue cracking in the main landing gear aft hanger link lug fittings can compromise the structural integrity of the airplane, potentially leading to failure under load. Operators and maintenance teams must comply to prevent undetected cracks from growing and causing unsafe conditions. Compliance ensures continued airworthiness and safety of the Boeing 787-8 fleet.
