Airworthiness Directive · Amendment 39-14742 · Bombardier Model CL-600-2B16 (CL-604) Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Bombardier Model CL-600-2B16 (CL-604) Airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Superseded. A later AD replaced this one: AD 2006-22-06. Comply with the one in force.
This AD applies to Bombardier Model CL-600-2B16 (CL-604) airplanes, serial numbers 5301 and subsequent; and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 7003 through 7990 inclusive and 8000 and subsequent; certificated in any category.
Note 1: The Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes may be referred to by their marketing designations as RJ100, RJ200, CRJ100, CRJ200, and CL-65.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B16 (CL- 604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, CRJ100, CRJ200, and CL-65. This AD requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. For certain airplanes, this AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. This AD results from reports of uncommanded horizontal stabilizer trim motion. We are issuing this AD to ensure that the flightcrew is advised of appropriate procedures to follow in the event of stabilizer trim runaway. Failure to follow these procedures could result in excessive uncommanded movement of the horizontal stabilizer trim actuator (HSTA) and loss of ability to use trim switches to override uncommanded movement or yoke disconnect switches to disconnect the HSTA, which could result in reduction of or loss of pitch trim control and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 7 days after the effective date of this AD, make the applicable AFM revisions specified in paragraph (f)(1) or (f)(2) of this AD by incorporating the applicable Canadair (Bombardier) temporary revisions (TRs) identified in Table 1 of this AD into the applicable AFM.
(1) For Model CL-600-2B16 (CL-604) airplanes: Revise the Emergency Procedures section of the AFM to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway.
(2) For Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes: Revise the Emergency and Abnormal Procedures sections of the AFM to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway and in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions.
| For Bombardier Model— | Use— | Dated— | To the— |
|---|---|---|---|
| CL-600-2B16 (CL-604) airplanes | Canadair Challenger TR 604/21 | August 1, 2006 | Canadair Challenger CL-604 AFM, PSP 604-1. |
| CL-600-2B19 (Regional Jet Series 100 & 440) airplanes | Canadair Regional Jet TR RJ/152-4 | August 9, 2006 | Canadair Regional Jet AFM, CSP A-012. |
(g) When the applicable TR has been included in the general revisions of the applicable AFM, those general revisions may be inserted into the AFM and the applicable TR may be removed, provided the relevant information in the general revisions is identical to that in the TR.
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.
