4.5 Fixing excessive free play of the canopy
Shrinking of the fibre reinforced plastic material may result in free play between
the canopy hinge 8R48 and the canopy.
You can fix the free play as follows:
a)
Take off the canopy and remove the emergency release spring.
b) Tape the hinge completely and coat it with demoulding agent.
c) Roughen the depression for the hinge at the canopy carefully with
abrasive paper.
d) Fix a piece of wood 10 by 10 mm (3/8 in.), 2 mm (1/12 in.) thick with
double-sided tape at the rear end of the hinge (see sketch).
Put on the canopy and try to lock the canopy to the hinge. If this is not
possible remove a small amount of the wood thickness.
If there is still free play, use a thicker piece of wood.
e) Mix epoxy resin with cottonflocks and apply it in the depression see c).
f) Reinstall, close and lock the canopy.
g) After the resin has cured, take off the canopy again.
h) Trim the depression, remove the tape, reinstall the spring and the canopy.
i) Finally check the canopy emergency release according to flight manual
section 7.16. The opening force for the emergency release should in no
case exceed 20 daN (44 lbs.)!
