Daily check-up
The daily check-up matches the preflight check-up.
Preflight check-up
WARNING!
Every single check-up mentioned in this chapter must be performed prior to
EVERY FLIGHT, regardless of when the previous flight took place!
The person responsible for the preflight check-up is the pilot from whom it is required
to perform the check-up in the utmost thorough and precise manner.
Provided the status of any of the parts and/or operations does not comply with conditions stated
in this chapter, the damage MUST be repaired prior to engine start-up. Disobeying this instructi-
ons may result in serious further damage to the plane and crew, including injury and loss of life!
Conducting the preflight check-up
Always perform the prefligtht check-up beginning and ending in the same position while walking
all around the powered-hangglider in-between. Always perform the preflight check-up immediately
before the flight itself.
Wing
Begin the check-up at the tip of the wing, where the front triangle wire ropes meet the middle main
spar. Verify that the pusk-pin is secured properly and run your hand over the wire ropes in both di-
rectios. This simple test will show whether any of the wire ropes is imperfect or even thorn. In this
case a small wire will pinch your finger. Next check all the linkage of the triangle, all rope-loops at
the ribs and the attachement joint between the wing and the trike. Do not forget to check the safety
loop between the wing and the trike.
Again, make sure that the swivels are in position. At the wingtips look inside the wing and make sure
that no stuts (tubes) show abnormalities, open the zippers at the side ripes and under the middle
main spar. Check everything you can see. Then close the zippers again. Make sure that the top pyra-
mide ropes are not interfeering with the ribs' rope-loops and check the push-pin at the top side of
the middle main spar.
Undo the main zipper, check the connection between the wing's spar and tightening straps. Touch
the middle main spar exactly below the point where the main wing's spar floats on top. There must
be a couple of centimeters between the middle main spar and wing's spar, otherwise the bolts of the
wing's spar may begin to grind and cut throught the middle main spar, which definitely leeds to an
serious accident. Should the wing's spar be lower than required, you may suspect the top pyramide
ropes are prolonged, which is usually a direct concequence of rough landings. In this case the top
pyramide ropes MUST be replaced.
