What to do
Operators of affected Bombardier BD-700-2A12 aircraft must inspect the aft fuselage skin area between fuselage stations FS945.75 and FS961.45 for missing fasteners and damage within 32 months from April 27, 2022. Any damage found must be repaired and missing fasteners installed following Bombardier Service Bulletin 700-53-7547 or later approved revisions. Compliance with these actions is mandatory before further flight if issues are detected.
Summary
Canadian Airworthiness Directive CF-2022-17 addresses missing fasteners in the aft fuselage structure of Bombardier Inc. model BD-700-2A12 aircraft, specifically serial numbers 70020 through 70039, 70041, 70046, and 70047. The directive mandates inspection and repair to ensure structural integrity of the fuselage skin attached to stringer 19. This directive aims to prevent potential skin deformation or cracking caused by missing fasteners under compressive loads.
What changed
CF-2022-17 introduces a new requirement for inspecting the aft fuselage structure of certain Bombardier BD-700-2A12 aircraft for missing fasteners and damage. It requires repairs and installation of any missing fasteners according to Bombardier Service Bulletin 700-53-7547. This is a newly issued airworthiness directive rather than an amendment to a previous one.
Why it matters
This directive is critical for operators and maintenance organizations to maintain the structural safety of affected aircraft. Missing fasteners can lead to inter-rivet buckling, which may cause permanent skin deformation or cracking, compromising the aircraft's structural integrity. Compliance ensures continued airworthiness and reduces the risk of in-flight structural failures.
