AD 2025-02-06 Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
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, with a nose radome having part number (P/N) C01204101-007 or P/N C01204101-009 and a serial number (S/N) S456997, S/N S570556, S/N S626945, S/N S866894, S/N T099675, S/N T471773, orS/N T595935.
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-2022-04, dated February 14, 2022 (Transport Canada AD CF-2022-04).
Unsafe condition
This AD was prompted by a report that the nose radome lightning diverter strips on certain aircraft were painted in production; paint on the diverter strips can compromise the nose radome lightning protection. The FAA is issuing this AD to address reduced effectiveness of the diverter strips, which can lead to the puncture of the nose radome by lightning and potential arc attachment to antennas, structures, and other equipment in the area of the nose radome. The unsafe condition, if not addressed, could result in damage to the localizer or glideslope antennas, and consequent loss of instrument landing system localizer inputs or deviation information.
Affected ADs
None.
