EASA AD CF-2024-28
Wings - Left Hand Main Landing Gear Fuse Pin Missing
Summary
Canadian Airworthiness Directive CF-2024-28 is an emergency directive addressing the missing left hand main landing gear fuse pin on Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft. This directive applies to specific serial numbers of these models and mandates inspections to ensure the presence and correct installation of the Pintle Fuse Pins in the main landing gear assembly. The directive aims to prevent potential landing gear collapse during takeoff due to missing or damaged fuse pins.
What Changed
This new emergency airworthiness directive introduces a mandatory detailed visual inspection of the left hand main landing gear Pintle Fuse Pins on affected Airbus Canada BD-500 series aircraft. It requires operators to verify the presence and proper installation of these pins within 24 flight cycles of the directive's effective date. If any pins are missing or incorrectly installed, operators must contact Airbus Canada for approved corrective actions before further flight.
Why It Matters
This directive is critical for aviation professionals because a missing or damaged Pintle Fuse Pin can cause a significant redistribution of loads in the landing gear assembly, potentially leading to gear collapse during takeoff. Compliance ensures the structural integrity and safety of the aircraft's main landing gear, reducing the risk of accidents and costly repairs. Maintenance and compliance teams must prioritize this inspection to maintain airworthiness and regulatory compliance.
What To Do
Operators of affected Airbus Canada BD-500-1A10 and BD-500-1A11 aircraft must perform a detailed visual inspection of the left hand main landing gear Pintle Fuse Pins within 24 flight cycles from August 3, 2024. If any fuse pins are missing or improperly installed, operators must contact Airbus Canada for an approved disposition and complete any required corrective actions before further flight. Documentation and adherence to the ACLP Alert Operators Transmission A220-AOT-57-21-001 are required.
