What to do
Operators of affected Bombardier BD-700-2A12 aircraft must re-torque the baggage compartment fire extinguishing tube assembly following Bombardier Service Bulletin 700-26-7503 or its approved revisions. Compliance is required within 28 months from the directive's effective date of December 29, 2021, unless already accomplished.
Summary
The Canadian Airworthiness Directive CF-2021-48 addresses a fire protection issue concerning the missing final torque value for the baggage compartment fire extinguishing tube assembly on Bombardier BD-700-2A12 aircraft with specific serial numbers. This directive mandates corrective action to ensure proper torque application on the fire extinguishing tube to maintain the integrity of the fire suppression system in the baggage compartment.
What changed
CF-2021-48 introduces a new requirement to re-torque the baggage compartment fire extinguishing tube assembly on affected Bombardier BD-700-2A12 aircraft. This action is necessary because the original assembly may not have been tightened to the correct torque during production, potentially compromising the fire extinguishing system.
Why it matters
This directive is critical for aviation professionals because improper torque on the fire extinguishing tube could lead to loss of the integrated fire suppression circuit in the baggage compartment, posing a safety risk during flight. Operators and maintenance teams must ensure compliance to maintain aircraft safety and regulatory adherence.
