Airworthiness Directive · Amendment 39-14508 · Bombardier Inc. Airplanes
Bombardier Inc. Airplanes
Superseded. A later AD replaced this one: AD 2006-05-11 R1. Comply with the one in force.
This AD applies to Bombardier Inc. CL-600-2B19 (Regional Jet Series 100), CL-600-2B19 (Regional Jet Series 440).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The existing AD currently requires revising the airworthiness limitations section of the Instructions for Continued Airworthiness of the aircraft maintenance manual (AMM) by incorporating procedures for repetitive functional tests of the pilot input lever of the pitch feel simulator (PFS) units. This AD requires new repetitive functional tests of the pilot input lever of the PFS unit, and corrective actions if necessary. After initiating the new tests, this AD also requires removal of the existing procedures for the repetitive functional tests from the AMM. This AD results from a report that the shear pin located in the input lever of two PFS units failed due to fatigue. We are issuing this AD to prevent undetected failure of the shear pin of both PFS units simultaneously, which could result in loss of pitch feel forcesand consequent reduced control of the airplane. DATES: This AD becomes effective March 27, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 27, 2006. On February 13, 2004 (69 FR 4234, January 29, 2004), the Director of the Federal Register approved the incorporation by reference of Bombardier Temporary Revision 2B-1784, dated October 24, 2003, to the CL-600-2B19 Canadair Regional Jet Maintenance Requirements Manual, Part 2, Appendix B, "Airworthiness Limitations.'' We must receive any comments on this AD by May 9, 2006.
