Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440)


Airplanes


AGENCY:
 
Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule.


–––––––––––––––––––––––––––––––––––


SUMMARY:
 
The FAA is superseding an existing airworthiness directive (AD), which applies to all


Bombardier Model CL-600-2B19 series airplanes. That AD currently requires revising the airplane


flight manual (AFM) to provide the flightcrew with operating limitations and procedures to enable


them to maintain controllability of the airplane in the event that aileron control stiffness is


encountered during flight. This new AD requires revising the Airworthiness Limitations section of


the Instructions of Continued Airworthiness to incorporate certain repetitive tasks for the aileron


control system and requires a briefing to advise flightcrews that certain aileron control checks are no


longer required. After accomplishing the applicable initial tasks, the existing AFM revisions for the


aileron control check may be removed from the AFM. This AD results from the development of


terminating actions for the AFM revisions. We are issuing this AD to prevent aileron control stiffness


during flight, which could result in reduced or possible loss of controllability of the airplane.


DATES:
 
This AD becomes effective October 6, 2005.


The Director of the Federal Register approved the incorporation by reference of Canadair


Regional Jet Temporary Revision 2B-2068, dated December 13, 2004, listed in the AD as of October


6, 2005.


The Director of the Federal Register approved the incorporation by reference of Canadair


Regional Jet TR RJ/109-2, dated August 9, 2002, as of October 10, 2002 (67 FR 60117, September


25, 2002).

SUPPLEMENTARY INFORMATION:


Examining the Docket


You may examine the airworthiness directive (AD) docket on the Internet at
 
http://dms.dot.gov


or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through


Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227)


is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES


section.


Discussion


The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include


an AD that supersedes AD 2002-19-07, amendment 39-12887 (67 FR 60117, September 25, 2002).


The existing AD applies to all Bombardier Model CL-600-2B19 series airplanes. That NPRM was


published in the Federal Register on June 22, 2005 (70 FR 36067). That NPRM proposed to retain


the requirements of the existing AD (i.e., airplane flight manual (AFM) revisions). That NPRM also


proposed to require revising the Airworthiness Limitations section of the Instructions of Continued


Airworthiness to incorporate certain repetitive tasks for the aileron control system and briefing


flightcrews that certain aileron control checks are no longer required. After accomplishing the


applicable initial tasks, the existing AFM revisions for the aileron control check may be removed


from the AFM.


Comments


We provided the public the opportunity to participate in the development of this AD. No


comments have been received on the NPRM or on the determination of the cost to the public.


Conclusion


We have carefully reviewed the available data and determined that air safety and the public


interest require adopting the AD as proposed.
