SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   82-23-08 CANADAIR: Amendment 39-4494. Applies to Canadair Model CL-600-1A11 airplanes certificated in all categories. Compliance is required as indicated to avoid possible failure of the throttle quadrant tungsten carbide wear strips and to preclude throttle movement directly from idle to cutoff. Within 50 hours time in service, or within 30 days after the effective date of this Airworthiness Directive, whichever occurs first, unless already accomplished, perform the following in accordance with Canadair Alert Wire TA600-0294/022 dated August 31, 1982:

A. Remove the throttle quadrant in accordance with Canadair approved procedures and inspect to positively identify part and serial numbers.

B. If the throttle quadrant is not identified by P/N 90601-65, reinstall in accordance with Canadair approved procedures and return to service.

C. If the inspection of paragraph A reveals that the aircraft is fitted with throttle quadrant, Canadair part number 90601-65, the following inspection must be conducted prior to each flight:

1. Unlatch and lift each thrust reverser lever in turn until it contacts its solenoid stop and, with friction off, apply a forward load of approximately 5 pounds to each main lever. Check to determine that the knob moves the normal amount (0.20 inch or less).

2. Unlatch and lift each thrust reverser lever until it contacts its solenoid stop. With the red shutoff latch held in the up position and with friction off, apply an aft load of approximately 5 pounds to the main lever. Check that this knob moves the normal amount (0.45 inches or less).

3. If movement is in excess of the values specified in paragraph (1) or (2) above, replace the quadrant with a serviceable model 90601-65 throttle quadrant in accordance with Canadair approved procedures and continue to inspect per Paragraph C., above.

4. With the thrust reverser levers down, check that the main levers cannot be moved aft into cutoff without lifting the red shutoff latch. If the lever can be moved aft, replace the quadrant with a serviceable model 90601-65 throttle quadrant in accordance with Canadair approved procedures and continue to inspect per Paragraph C., above.

D. For aircraft fitted with throttle quadrant, part number 90601-65, install the following placard on the instrument panel in full view of the pilot, using letters of 3/8 inch minimum height: "Do not conduct planned go-around and missed approach operations."

E. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA Northwest Mountain Region.

F. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.

It is anticipated that this AD will be amended to provide terminating action when the manufacturer has developed an acceptable modification.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

This amendment becomes effective November 22, 1982.
