Accomplishment: Before 15 August 2005.

Reason:

Glue failure causing detachment of end rib and control horn from elevator tab resulting in free floating tab that induced elevator flutter.

Instructions:

Gain access to the elevator tab inboard end rib. On some installations it may be necessary to remove a small amount of fabric and/or paint to gain access. Inspect the tab end rib joint for any signs of dis-bonding. Apply gentle side forces to tab control horn and inspect for any looseness or gaps or dis-binding between the rib and tab surfaces that might indicate glue failure. Any defects must be investigated, reported to the BGA and rectified before flight. Restore any paint or fabric removed for the inspection. Record findings and compliance in glider log book.
