(a)
Do not use bubble wrap as protection for the aircraft wing. NOTE : The protection is a laminate of fiberglass-reinforced
____ polyester SPECIAL MATERIALS (Material No. 05-109), which has a minimum thickness of 1.2 mm (0.06 in.). It is thin, impact resistant and applies the load equally to prevent damage to the wing.
(b)
Put an ACCESS PLATFORM 5M (16 FT)- ADJUSTABLE in position adjacent to the wing, to help you attach the protection.
(c)
Attach the protection in position: CAUTION : MAKE SURE THAT THE PROTECTION IS CORRECLTY ATTACHED
_______ WITH TAPE TO THE AIRCRAFT STRUCTURE. THIS PREVENTS THE SUCTION OF LOOSE MATERIAL INTO THE ASPIRATOR DURING DEPLOYMENT. LOOSE MATERIAL CAN CAUSE DAMAGE TO THE ASPIRATOR.
