Models named: BD-500-1A10, BD-500-1A11. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2023-24, dated April 6, 2023 (Transport Canada AD CF-2023-24).

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2023-24.

Unsafe condition

This AD was prompted by damage found on two variable frequency generator (VFG) power-feeder harnesses on three airplanes due to chafing with wheel bins. An investigation found that the power-feeder harnesses were not adequately supported to protect from chafing due to vibration. The FAA is issuing this AD to prevent damage to VFG power-feeder harnesses from chafing due to vibration. The unsafe condition, if not addressed, could lead to a loss of generated power from both VFGs, or to a fire in the case of flammable fluid contact with arcing wires.

Affected ADs

None.
