Applicability*9
This AD applies to De Havilland Aircraft of Canada Limited (type certificate previously held by Bombardier, Inc.) Model DHC-8-401 and -402 airplanes, certificated in any category, as identified in Transport Canada AD CF-2025-19, dated March 24, 2025 (Transport Canada AD CF-2025-19).
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-2025-19.
Unsafe condition
This AD was prompted by multiple in-service reports of cracks found in the elevator power control unit (PCU) brackets (fittings) and the elevator front spar. The FAA is issuing this AD to address such cracks, which could result in failure of an elevator PCU bracket and lead to an elevator jam. The unsafe condition, if not addressed, could, if both elevators are affected, result in the loss of pitch control.
Affected ADs
None.
