STRUCTURAL INSPECTION
Applicable to all Diamant models, all serial numbers. Information has been received of a flight structural failure of a Diamant glider. Investigation has reveled the presence of a defect in the 'tongue' spar extension of the 'tongues and forks' wing spar joint; this defect was in the form of a crack extending vertically up from the main rigging pin hole. Propagation of this crack led to the delamination of the spar flanges and failure of the wing. Investigation of the wing structure reveled other defects which were not primarily the cause of failure.
