AD 82-07-01

82-07-01 VICKERS-SLINGSBY: Amendment 39-4352. Applies to Model T.65A Vega gliders certificated in all categories which do not have Vickers-Slingsby Modification No. 12 incorporated.

Compliance is required as indicated.

To prevent inadvertent extension of the airbrakes during high speed, low level flight conditions in turbulent air, which could result in loss of control of the glider, accomplish the following:

1. Within the next 10 hours time in service after the effective date of this AD, unless already accomplished or until the modification required by paragraph 2 of this AD has been accomplished, install a placard on the flap/airbrake control in accordance with Vickers- Slingsby Technical Instruction No. 82, Issue 1, dated June 11, 1979. The placard must read as follows:

"TEMPORARY RESTRICTION Maintain contact with flap handle during high speed in -8 degree flap position."

2. Modify the flap/airbrake control system in accordance with the instructions under "PROCEDURE" of Vickers-Slingsby Technical Instruction No. 85 by September 17, 1982, unless already accomplished. The placard required by paragraph 1 may be removed when this modification is accomplished. An equivalent means of compliance may be approved by the Chief, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, C/O American Embassy, Brussels, Belgium, or the Chief, Boston Aircraft Certification Branch, ANE-150, Federal Aviation Administration, 12 New England Executive Park, Burlington, Massachusetts 01803.

This amendment becomes effective March 25, 1982.
