PREFLIGHT INSPECTION
: A Pre-flight inspection must be done before each flight, without haste
and methodically.
Any Microlight (ULM) Flight Training Course teaches that the beginning of Flight Safety is a good
and thorough PREFLIGHT. You must apply this teaching.
Note: the cables should be checked by sliding your hand along them; also turn the swaged cable
end hearts to detect signs of wear.
•
Start at the nose of the wing.
•
Raise the nose cap and check the security of the connection of the upper and lower cables
•
Verify the security of the tension lever, the pit pin and its safety cap.
•
Replace the nose cap.
•
Move towards the end of the wing sliding you hand along the leading edge to check that it
is not deformed, and that the leading edge fabric does not show any trace of impact, of
tears or non-standard wear.
In the event of abnormal wear or of impact marks, the tubes of
leading edge MUST BE CHECKED. The wing MUST be disassembled.

At the back of the keel, check that the upper cable and the lower cables, the two cross spar
tensioning cables, the security and the position of the tensioning lever, the security of the
pit pin and the safety cap (2),
•
Check the airworthy condition of the keel pocket of skittle and the safety strap
