AD 2014-17-04 Airworthiness Directives; Bombardier, Inc. Airplanes
Applicability*9
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 and subsequent.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 6,600 flight hours or 48 months after the effective date of this AD, whichever occurs first: Replace the elevator PCU shear pins, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-55-008, Revision B, dated March 12, 2014. Repeat the replacement thereafter at intervals not to exceed 6,600 flight hours or 48 months from the most recent replacement, whichever occurs first.
Unsafe condition
This AD was prompted by reports that elevator power control unit (PCU) shear pins may fail prematurely. We are issuing this AD to prevent premature elevator PCU shear pin failure. If all pins fail on one elevator, the elevator surface would become inoperative, which could reduce the controllability of the airplane and could result in a loss of redundancy for flutter prevention.
Affected ADs
None.
