What to do
Operators of Bombardier BD-700-1A10 and BD-700-1A11 aircraft must inspect and rectify the engine FIREX bottle squib connector wiring according to the applicable Bombardier service bulletins within 1000 flight hours or 15 months from the effective date of the AD, whichever occurs first. Compliance with later approved revisions of the service bulletins also satisfies the directive requirements.
Summary
Airworthiness Directive CF-2018-08R1 is a Canadian regulatory document addressing a wiring length discrepancy in the engine fire extinguishers' squib connectors on Bombardier BD-700-1A10 and BD-700-1A11 aircraft, serial numbers 9001 to 9839 and 9998. This directive mandates inspection and correction of the squib connector wiring to ensure proper function of the engine fire extinguishing system. The directive references specific Bombardier service bulletins for corrective actions.
What changed
CF-2018-08R1 revises the original AD CF-2018-08 by correcting an error in the applicability section concerning affected aircraft serial numbers. It continues to require compliance with Bombardier service bulletins that address the non-conforming squib connector wire harnesses installed on engine FIREX bottles.
Why it matters
This directive is critical for aviation professionals because improper wiring of the engine fire extinguisher system can cause cross-connection or limited fire extinguishing agent supply, potentially compromising engine fire suppression. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and regulatory conformity.
