other transverse member. This line must be accurate – to within ¼ degree, which is easily obtainable
with hand tools.
Step 3: Take a small digital level and note the current lateral (roll) and longitudinal (pitch) tilt of the
aircraft as it sits, using the criteria determined in step 1. Make sure getting in and out of the aircraft
doesn’t change its position.
Step 4: Now shim the SG102 mounting base to reproduce the same pitch and roll tilt angle as the
airframe. Tighten the base mounting screws friction tight.
Step 5: Adjust the longitudinal axis of the mounting base so that it is parallel with the longitudinal axis
pencil line. Align Visually.
Step 6: Tighten the mounting screws. Make sure these are going into self-locking nutplates. The base
should be extremely stiff and shouldn’t slip.
Step 7: Install the SG102 into the base by sliding it into the rear hold-down, tighten the clamp, and
safety wire the clamp screws.
