Applicability*9
This AD applies to Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2022-67, dated December 6, 2022 (Transport Canada AD CF-2022-67).
Compliance

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-2022-67.
Unsafe condition
This AD was prompted by reports of the failure of emergency locator transmitter (ELT) antennas, including an in-service failure that occurred before the repetitive replacement interval required by AD 2021-09-03, and by the development of a terminating action. The FAA is issuing this AD to address ELT antenna failure. The unsafe condition, if not addressed, could result in loss of the ELT antenna and the development of fuselage cracks that can result in an inability to maintain cabin pressure.
Affected ADs
This AD replaces AD 2021-09-03, Amendment 39-21516 (86 FR 20266, April 19, 2021); corrected April 27, 2021 (86 FR 22111) (AD 2021-09-03).
