AD Jonker Sail planes vliegtuigen

Bericht door Jan Ritsma » 14 mar 2021, 12:52

Manufacturer(s): M&D Flugzeugbau GmbH & Co. KG

Applicability: JS-MD 1C sailplanes, all manufacturer serial numbers.

Definitions: For the purpose of this AD, the following definitions apply:

Affected part: Airbrake Blade No. 3 (bottom blade).

The SB: M&D Flugzeugbau GmbH & Co. KG Mandatory Service Bulletin (SB) SB-MD01-004 Revision 1.

Reason: Occurrences were reported of interference between the affected part and the edge of the airbrake cap recess during rapid airbrake extension. Subsequent investigation determined that insufficient space existed between the moving parts and wing structure, which caused the interference.

This condition, if not corrected, could lead to blockage of the airbrakes, possibly resulting in reduced control of the sailplane.
