EASA AD CF-2019-19R1
Fuel Distribution - Fuel Feed Tube Damage at Bonding Clamp Location Inside the Fuel Tank
Summary
Airworthiness Directive CF-2019-19R1 addresses fuel feed tube damage at the bonding clamp location inside the fuel tanks of Airbus Canada Limited Partnership BD-500-1A10 and BD-500-1A11 aircraft. This directive mandates inspections and modifications to prevent fuel tube failure that could cause fuel imbalance or engine shutdown. It applies to specific serial numbers of these aircraft models.
What Changed
This revision supersedes AD CF-2019-19 by adding mandatory compliance with ACLP Service Bulletin BD500-282004, which requires modification of the affected fuel feed line installations. Compliance with this modification terminates the previous inspection requirements mandated by the earlier AD. The directive is considered an interim action pending further regulatory updates.
Why It Matters
The directive is critical for operators and maintenance organizations to prevent potential fuel feed tube failure that can lead to severe fuel imbalance or in-flight shutdown of one or both engines. Ensuring compliance reduces safety risks and maintains airworthiness. It also provides clear instructions for inspections and modifications to mitigate identified wear damage.
What To Do
Operators must inspect affected fuel feed tubes within 1800 flight hours from 27 May 2019 if not already done, and perform repetitive inspections at intervals not exceeding 1800 flight hours until modification is completed. The fuel feed line modification must be completed within 3600 flight hours from the effective date of this AD, 15 November 2019. Compliance with the modification terminates the inspection requirements.
