Plain English Summary

3/10 complexity

This Airworthiness Directive requires operators of Bombardier CL-600-2B19 (Challenger) aircraft to insert AFM Temporary Revision RJ/109-2, include a copy of this Directive in each AFM, and advise flight crews. The TR amends emergency procedures for aileron jams (applies to all aircraft) and adds an aileron-control check to the Limitations for aircraft with over 5,000 total flight hours; compliance is within 14 days of 28 August 2002.

The measure responds to reports of aileron stiffness after takeoff in heavy rain or from contaminated runways; the amendment raises the minimum altitude at which the control check must commence.

Amdt 1

Aileron Stiffness 10/2002 DM

Applicability: All CL-600-2B19 aircraft.

Requirement: 1. Amend the Aircraft Flight Manual (AFM) by inserting Temporary Revision (TR) RJ/109-2 dated 9 August 2002. TR RJ/109-2 introduces the following:

An amendment to Emergency Procedures for aileron system jams. This change is applicable to all aircraft.

b. An aileron control check procedure to the Limitations Section. This change is applicable to aircraft that have accumulated 5,000 total flight hours.
2. Insert a copy of this Directive in each AFM.

3. Advise all flight crews on the changes introduced through the AFM TR.

Note: Transport Canada AD CF-2002-35R1 refers.

Compliance: Within 14 days after 28 August 2002, unless already accomplished.

This amend ment becomes effective on 28 August 2002.

Background: A significant number of reports of aileron control stiffness have been received following climb to altitude after takeoff from a contaminated runway or during heavy rain. In every case, the aileron stiffness disappeared upon descent to lower altitude and the aircraft landed safely. The aircraft that have encountered aileron control stiffness had accumulated in excess of 5,000 total flight hours when the problem appeared.
