This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 7003 and subsequent, certificated in any category, that are equipped with Thales angle of attack (AOA) transducers having part number (P/N) 45150340 or C16258AA.

Unless already done, do the following actions. (1) For airplanes equipped with a transducer having accumulated 7,500 or fewer flight hours as of March 9, 2009, except transducers that have been measured in accordance with paragraph (f)(1) of this AD: Do the actions specified in paragraph (f)(1) of this AD before the transducer accumulates 7,500 total flight hours, or within 500 flight hours after the effective date of this AD, whichever occurs later. (2) Within 900 flight hours after the effective date of this AD, inspect AOA transducers having P/N 45150340 or C16258AA to determine the serial numbers. A review of airplane maintenance records is acceptable in lieu of this inspection if the serial number of the AOA transducer can be conclusively determined from that review. (i) If the serial number is not identified in paragraph 1.A.(1) of Bombardier Service Bulletin 601R-27-154, dated December 1, 2008, no further action is required by this paragraph. (ii) If the part number and serial number are identified in one of the tables in paragraph 1.A.(1) of Bombardier Service Bulletin 601R-27-154, dated December 1, 2008, and have the suffix “A,” no further action is required by this paragraph. Note 1: Bombardier Service Bulletin 601R-27-154, dated December 1, 2008, references Thales Avionics Service Bulletins 45150340-31-004 and C16258A-27-002, both dated November 28, 2008, as additional sources of guidance for part and serial number information. (iii) If the part number and serial number are identified in a table in paragraph 1.A.(1) of Bombardier Service Bulletin 601R-27-154, dated December 1, 2008, before further flight, replace the AOA transducer with a new or serviceable transducer, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-27-154, dated December 1, 2008. (3) As of the effective date of this AD, no person may install a replacement AOA transducer having P/N 45150340 or P/N C16258AA with a serial number identified in paragraph 1.A.(1) of Bombardier Service Bulletin 601R-27-154, dated December 1, 2008, unless the serial number has the suffix “A.” FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
