TM 55-1520-238-S
G6 FUEL VENTS:
WARNING
Do not attempt to patch, shrink, or fuse the heat shrink material with the heat
cannon after fuel vents have been unsealed.
CAUTION
Adequate ventilation of the cover is essential to minimize condensation and
permit drainage.
After the inspection of the covering has been completed and the covering has been found satisfactory, the fuel vents
must be unsealed. Cut a small slit in the area of the vent and remove the seal. Repair the cut with tape. Repeat this
process for each fuel vent.
G7 INSTALLATION OF VENTILATORS:
After the inspection of the covering has been completed, the covering must be ventilated. Ventilators are to be placed
to allow a flow of air through the covering. Each aircraft will require approximately five ventilators. They should be
placed to allow air to flow through the helicopter. At least one vent will be required at each low point on the helicopter
to drain condensation. The vents are applied by peeling the backing off the adhesive surface and pressing the vent
to the shrink film. The vent cover is then removed and the center hole is cut in the shrink film. The vent cover is then
replaced and secured with tape.
G8 ACCESS TO HELICOPTER:
After the shrink film process has been completed, access to the cockpit area may be required for the operation of the
brakes. If access is required, cut the shrink film in the outline of the door on three sides. Fold the film out of the way
and open the door. After the operation is complete, the cover can be resealed with heat shrink film and/or tape. Insure
that a good seal has been accomplished.
G9 HOISTING:
If the helicopter is being hoisted on a vessel or truck, the heat shrink film will be cut at the rotor head area where the
sling is installed. After the hoisting task is complete, the cut film may be closed with two inch heat shrink tape and/or
a piece of heat shrink film taped to the cover to seal the rotor head area.
G10 TIEDOWN POINTS:
Tiedown points, two forward fuselage and one station 450, will protrude through the heat shrink film. After loading
aircraft, restrain it in accordance with either Chapter 3 or 4 of this manual as appropriate.
G11 PROTECTION OF WHEELS AND BRAKES (TOP DECK OF VESSEL):
After the aircraft is secured, the wheel and brake areas may be protected by securing heat shrink film tightly around
them with heat shrink tape. Do not attempt to shrink the film.
G12 ENROUTE MAINTENANCE:
Shrink covers should be checked daily by designated escort personnel and/or vessel crew for damage. Damaged
areas may be repaired by patching the shrink film using two inch heat shrink tape. Main landing gear struts will be
inspected daily for proper inflation and serviced as necessary. Cuts made to access the struts may be repaired with
2" heat shrink tape.
G13 REMOVAL OF SHRINK FILM:
To remove the shrink film, use the safety knife and cut along the top and side surfaces. The shrink film does not adhere
to the helicopter and will fall away.
CAUTION
Use only the safety knife when removing the film. A standard knife blade will
damage the helicopter.
