SCHEMPP-HIRTH FLUGZEUGBAU GmbH., KIRCHHEIM/TECK Duo Discus MAINTENANCE MANUAL After cleaning the entire aircraft, the following checks should be made: • Check the aircraft externally for damage such as cracks, holes, scratches, buckling and delamination. If the outer layer(s) of a component, constructed as a sandwich, has been damaged, then the inner skin must be checked as well. It is recommended to call upon expert assistance. • All fittings which are mounted on GFRP (CFRP) structures must be checked to confirm there has been no movement. Check also the CFRP (GFRP) structure at the fittings for cracks, white spots and delamination. • Check all accessible metal parts for damage. It is generally found, however, that if the aircraft is operated correctly, no damage will have occured. If repairs are necessary, then the manufacturer’s recommendations should be followed. • Check all accessible metal parts such as fittings, control rods (push/pull tubes) and actuating levers for corrosion. If necessary, remove the rust, clean thoroughly and apply a fresh corrosion protection. The special primer and paint for this surface protection may be obtained from Schempp-Hirth Flugzeugbau GmbH. • Linkage for attaching and locking the canopy Check linkage attaching/detaching and locking/opening the canopy for any damage. Check guides for locking rod on canopy frame, locating pins on fuselage and front GFRP hinge for delamination/cracks. Check rear metal hinge for deformation.
