EASA AD US-2024-05-03
Fuselage - Forward Entry Door and Service Door Cutout Aft Lower Corner Fuselage Skin and Bear Strap - Repetitive Inspections
Summary
Fuselage - Forward Entry Door and Service Door Cutout Aft Lower Corner Fuselage Skin and Bear Strap - Repetitive Inspections is a Federal Aviation Administration (FAA) Airworthiness Directive (AD 2024-05-03) that applies to certain Boeing Model 767 airplanes. It addresses the detection of cracks in the aft lower corner fuselage skin and bear strap near the forward entry and service door cutouts. The directive mandates repetitive inspections and necessary corrective actions to maintain structural integrity.
What Changed
This new AD introduces mandatory repetitive inspections for cracking in the specified fuselage areas of Boeing 767 models and requires on-condition repairs if cracks are found. It also clarifies acceptable repair methods, includes the B767-300BCF Structural Repair Manual as a compliance option, and defines compliance time terms specific to the Model 767-2C. The AD does not exempt repairs approved via Form 8110-3 from needing an Alternative Method of Compliance (AMOC).
Why It Matters
This AD is critical for aviation professionals because undetected fatigue cracks in the fuselage could compromise the airplane's structural integrity and safety. Operators and maintenance teams must implement the repetitive inspections and repairs to prevent potential structural failures. Compliance ensures continued airworthiness and regulatory adherence, minimizing operational risks and avoiding costly unplanned repairs.
What To Do
Operators of affected Boeing 767 airplanes must perform the required repetitive inspections of the forward entry and service door cutout aft lower corner fuselage skin and bear strap starting by May 8, 2024. If cracks are detected, applicable on-condition repairs must be completed following approved procedures. Operators should also ensure repair approvals comply with the AD’s AMOC requirements and reference the updated Structural Repair Manuals where applicable.
