Airworthiness Directive · Amendment 39-16251 · Landing gear
Bombardier, Inc. Model BD-100-1A10 (Challenger 300) Airplanes
This AD applies to Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes, certificated in any category, serial numbers 20002 through 20153 inclusive.
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:
Unless already done, within 14 days after the effective date of this AD: Revise the Limitations Section of the Bombardier Challenger 300 AFM, CSP 100-1, to include the information in Bombardier Temporary Revision TR-39, dated March 2, 2005, as specified in the temporary revision. This temporary revision introduces a procedure for “PROX SYS FAULT (A)” and modifies the “WOW FAIL (C)” and “GEAR SYS FAIL (C)” procedures.
Note 1: This may be done by inserting a copy of Bombardier Temporary Revision TR-39, dated March 2, 2005, in the AFM. When this temporary revision has been included in general revisions of the AFM, the general revisions may be inserted in the AFM, provided the relevant information in the general revision is identical to that in Bombardier Temporary Revision TR-39, dated March 2, 2005.
Note 2: If the aircraft has incorporated a PSEU, part number (P/N) 30227-0401, 30227-0402, or 30227-0403, with software version 12, installed in accordance with Bombardier Service Bulletin 100-32-12, dated June 4, 2007, it is permissible to follow the revised AFM procedures included in Bombardier Temporary Revision TR-46, dated March 27, 2008, in lieu of using Bombardier Temporary Revision TR-39, dated March 2, 2005, specified in paragraph (f) of this AD.
Note 3: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
