AD: Bombardier

AD NUMBER: AD 2009-10-05

MANUFACTURER: Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) Airplanes
SUBJECT: Airworthiness Directive AD 2009-10-05

 

SUMMARY:  We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
 

  • A number of Flap Actuators with P/N [part number] 601R93101-21 and 601R93101-25 were identified as having pinion gears that did not have acceptable certificates of conformance from the supplier. This condition could result in flap failure. 

Endurance testing conducted at Eaton Aerospace with representative discrepant gears predicted a 3,000 flight cycle life limit for the affected actuators. Fleet leaders with suspect installed actuators are rapidly approaching this threshold. Failure of the flap actuator pinion gear set could cause the right or left inboard panel to disconnect, which could result in flap asymmetry and consequent reduced controllability of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
