LONGITUDINAL CRACKING OF THE LEADING EDGES OF THE WING AND HORIZONTAL TAILPLANE
Applicable to the SZD-36, SZD-36A and SZD-39 Cobra glider. PZL Bulletin BR-004/80 details the inspection for and repair of cracks found, in the leading edges. Cracking is largely caused by exposure of the glider to moisture under inadequate storage conditions.
