STIFFENING OF THE AIRBRAKE SYSTEM SUPPORTS IN THE WING ROOT RIB AREA
Applicable to the Glaser Dirks DG-300 (Elan), serial numbers 3 E 1 to 3 E 264 inclusive. The manufacturer has issued Technical Note No. TN 359/14 (which forms part of this Airworthiness Directive) following DG-300 (Elan) gliders being found overseas with delamination or lack of original bonding between the wing shell and the ribs supporting the Airbrake drive torque tubes at each wing root. Any freedom or loss of stiffness in those supports can reduce the over centre load locking the Airbrakes in. One or both Airbrakes may then prematurely extend during loads generated by high speed flight or when responding to "G" forces. Glaser Dirks TN No. 359/14 forms part of this Airworthiness Directive including drawing No. DG 3F37.
