S-7S AILERON AND FLAP ASSEMBLY AND INSTALLATION
ASSEMBLY
(BEFORE COVERING)
1. Aileron and Flap Frames are factory assembled.
2. Install nut plates for the hinges to the AFT side (inside) of the Flap Frame
Leading Edge Spar before covering.
NOTE: Aileron Frames do NOT
require nut plates for hinge attachment .
3. To install nut plates, temporary insert a bolt through the hinge hole into a
nut plate. Drill # 40 using the nut plate as a guide and rivet.
IMPORTANT:
Before drilling, be sure the nut plate is aligned with the frame spar. Using
this method will assure a perfect fit.
4. The Flap and Aileron Frames are now ready for covering. Refer to
COVERING .
(AFTER COVERING AND PAINT)
5. Use a hot iron (a soldering iron or wood burning tool works well) to burn
holes through the fabric at the attach points for the Flap Hinges, the Flap
and Aileron Attach Angles and through Drain Grommets. Refer to parts
pages and
FIGURE 05D-05 .
6. Bolt Hinge Brackets to leading edge of Flap Frame.
7. Aileron Hinges must be bolted to the Wing Trailing Edge Spar before
bolting to the Aileron Frame.
IMPORTANT: Be sure to check the
orientation of the Aileron Hinge.
8. Bolt on Flap Horn Attach Angles and Aileron Attach Angles. NOTE: Flap
and Aileron Attach Angles are orientated 90 degree to the Aileron or Flap
Leading Edge.
You will have to fabricate small bushings as per parts
manual. Locate and burn small holes through the fabric at the bushing
locations. Refer back to
FIGURE 05D-05 . NOTE: Flaps require two Attach
Angles, whereas Ailerons use only one. See FIGURE 05D-08 .
