tear in our premises. The results of the test will determine when the replacement of the
sail becomes essential for safety reasons.
Protection
Ultraviolet radiation from strong sunlight can ultimately reduce the strength of the
sailcloth, but this may be reduced to an acceptable level by careful consideration of the
wings use and exposure. In its bag the wing is fully protected. The sailcloth may be
cleaned with warm soapy water. Strong detergents must not be used. Thoroughly rinse
with plenty of clean water.
Minor Tears or Rips in the Sail
Minor repairs may be carried out by the owner of the aircraft, unless local regulations
prohibit owner maintenance for sails. A repair is classified as minor if tears are less than
20mm long, provided that no free edges (such as the wing trailing edge) are broken and
that the tear is isolated and not within 50mm of an existing seam line or 100mm of the
trailing edge. Also, abraded holes no more than 15mm in diameter are considered minor.
Such damage may be replaced with self-adhesive patch material (often called “sail tape”
or “sticky back sail repair tape”) such as used for registration letters, if possible to both
sides of the fabric.
This tape is available from Air Creation.
Any other significant damage should be discussed with Air Creation or a technical station
for an assessment of the best repair option.

Special Purpose Equipment
Training Bar Maintenance
Refer to
drawing U028271-M090
.
The training bars are likely to be installed and removed often, therefore it is important
that the components are accounted for each time that they are removed and installed. The
bars are port and starboard sides, and need to be installed on the inside of the down tubes.
They should be inspected for bending, and at each of the bolt holes and welds as well as
any other wear that may occur each time they are installed. Check the condition of the
rubber top fitting too and change them if there is any kind of cracks.
Also check the
straps, buckles and Velcros of the top bracket on the uprights
.
If they are permanently
affixed to the aircraft they need to be inspected at regular intervals. The frequency of
inspection will depend on the amount that they are used. Prior to each flight they should
be checked to ensure that they are securely attached to the uprights and base bar.
The welded base bar attachment has been made to be slightly loose, for ease of assembly.
