A thorough pre-flight procedure is mandatory with all aircraft, however, and the best technique is acircular walk around the glider.Start at one location, the nose plate for example and check each assembly pointavailable for inspection. Keep in mind the THREE MOST CRITICAL set-up factors.These are the nose catch; the control frame base tube bolt and the cross tubetension cables attaching to the spring catch on the keel. As stated in the set-upprocedure, ENSURE THAT ALL SECURING PINS ARE PROPERLY POSITIONE DAND CANNOT PULL THROUGH.Starting at the nose, a suitable pre-flight checklist would be:1) Sight along both leading edges checki ng for similar curves.2) Walk towards the tip feeling for dents in the tube.3) Pause at the wing bolts and look into the sail through thevelcro ope ning (under surface sea m).4) Continue to the ti p and check the tip wand.5) Walk to the keel che cking the battens to ensure that they a reprope rly secure d.6) Check the luff line attachm ent points, both at kingpost andtrailing edge grommets. Ensure that the luff lines are not wrappe daround the batte n ends.7) Check the cross tube wire to spring catch connection.8) Check the rear top rigging and luff line attachments.9) Repeat items 2 to 7 in reve rse order.10) Check the nose catch. |
