CRACKING AND DETACHMENT OF FLAP MASS BALANCE LEAD STRIPS

Applicable to all PIK 20 series sailplanes and powered sailplanes with mass balanced flap/aileron systems. One confirmed and one unconfirmed report of flap, lead mass balance strips cracking at their attaching rivet holes, in one case pieces detaching caused aileron control system restriction in flight. Not all of the PIK series sailplanes have mass balancing of flaps or ailerons. Applicability of this airworthiness directive must be determined by inspection.
