Parts Ordering and Parts Replacement
Wills Wing policy requires, for safety reasons, that replacement parts be ordered through an authorized
Wills Wing dealer. The purpose of this policy is to insure that the parts will be delivered to someone
who has the required expertise to install the parts properly. We have seen multiple examples of
incidents in which a pilot's life was endangered as a result of the incorrect installation of replacement
parts, or incorrect assembly of a glider.
The serial number of the glider is required when ordering any fabricated replacement part. The serial
number is a five digit number which can be found in several places on the glider; on an embossed label
on the bottom of the front of the keel tube, on the operating limitations placard on the bottom of the
rear of the keel, and written inside the nose area of the sail. In addition to the serial number, you
should provide any relevant information regarding configuration options for the glider in question.
When replacing a part on the glider, always compare the old part with the new part to make sure that
the new part appears to be the correct item. If you have any question, contact Wills Wing. Also, be
sure to do a thorough inspection of the glider after the installation of the part, to insure that the part has
been installed correctly, and appears to be functioning correctly, and that the rest of the glider is
properly assembled.
Every Six Months
1. Check the adjustment of your sprogs, as described in the last section.
2. Check your battens on a flat level floor against the batten diagram provided, and correct any that
deviate from the pattern by more than 1/4".
3. If you fly in a dusty or sandy environment, it will help to prolong the life of your batten pockets if
you wipe each batten with a rag before you install it in the sail.
4. Inspect all cables and suspension system components, and replace any suspension system compo-
nent that shows any wear, and any cable that shows any kinks, wear, damage, corrosion, etc.
5. Inspect all bolts and nuts for tightness, all safeties for proper installation and possible damage.
Inspect plates and fittings for damage, holes in tubes for elongation. Inspect the ball lock pins for
any sign of damage or wear and replace the pins if damage or wear is found. Inspect the keyhole
tang button locking mechanisms at the nose and rear keel for proper operation - adjust or replace
as necessary if the button locks do not operate smoothly and engage fully.
6. Inspect the sail for wear, tears, UV damage, loose stitching, etc.
7. Check for free operation of all pulleys. Disassemble, clean and / or lubricate or replace as
necessary. Inspect all VG ropes for wear or damage and replace if necessary.
8. Lightly spray any zippers on the glider that show indication of excess friction with silicone spray
lubricant. Do not use any other type of lubricant. Wipe off any excess silicone so that it does not
attract dirt.
9. Inspect the sprogs, sprog hardware and sprog cables. If the sprogs have been loaded heavily, it is
possible that the sprog tubes may have been bent, and the cables may have been stretched. (Note
- the Sport 2 sprog tubes are preformed with a bend to accommodate the change in section of the
sail at the aft edge of the bottom surface - this is normal.)
