Airworthiness Directive · Amendment 39-18502 · Flight controls
Bombardier, Inc. Airplanes
Superseded. A later AD replaced this one: AD 2016-13-02. Comply with the one in force.
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 through 7067 inclusive, 7069 through 7990 inclusive, and 8000 through 8999 inclusive.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by the discovery of a number of incorrectly calibrated angle of attack (AOA) transducers installed in the stall protection system. This AD requires replacement of incorrectly calibrated AOA transducers. We are issuing this AD to detect and replace incorrectly calibrated AOA transducers; incorrect calibration of the transducers could result in late activation of the stick pusher.
For AOA transducers identified in paragraph 1.A., “Effectivity,” of Bombardier Service Bulletin 601R-27-164, dated March 30, 2015: Within 2,500 flight hours or 12 months, whichever occurs first after the effective date of this AD, replace the AOA transducers with correctly calibrated AOA transducers, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-27-164, dated March 30, 2015.
