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 through 7067 inclusive, 7069 through 7990 inclusive, and 8000 through 8999 inclusive.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

This paragraph restates the requirements of paragraph (g) of AD 2016-09-04, with no changes. 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 June 6, 2016 (the effective date of AD 2016-09-04), 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.

Unsafe condition

This AD was prompted by the discovery of a number of incorrectly calibrated angle of attack (AOA) transducers installed in the stall protection system. 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.

Affected ADs

This AD replaces AD 2016-09-04, Amendment 39-18502 (81 FR 26102, May 2, 2016) (“AD 2016-09-04”).
