What to do
Operators must prohibit installation of affected sensing elements on Group B aeroplanes from 11 April 2022 and verify maintenance records within 30 days of that date. Testing and replacement of affected sensing elements must be completed within 2450 flight hours or 18 months for Group A aeroplanes and certain Group B aeroplanes, and within 9350 flight hours for other affected parts. Marking of serviceable parts is required before further flight.
Summary
Airworthiness Directive CF-2022-13R1 is issued by Transport Canada concerning Airbus Canada Limited Partnership aeroplanes Model BD-500-1A10 and BD-500-1A11. The directive addresses non-conforming bleed leak detection system sensing elements that may have insufficient salt fill, potentially impairing the detection of hot bleed air leaks. This condition affects the safety of the aircraft by risking damage to structures and systems critical for safe flight and landing.
What changed
This revision of AD CF-2022-13 corrects an error in the affected part definition by aligning it with the Kidde Aerospace and Defense service bulletin Section 3.C. It clarifies which sensing elements are considered affected or serviceable and updates installation prohibitions and testing requirements accordingly. The directive supersedes the original AD CF-2022-13 issued on 28 March 2022.
Why it matters
The directive is critical for operators and maintenance organizations to ensure that bleed leak detection systems function correctly to detect hot bleed air leaks. Failure to comply could result in undetected leaks causing structural damage and compromising flight safety. Compliance teams must update maintenance programs and verify parts to avoid installation of non-conforming sensing elements.
