Jacking Information; Leveling The Aircraft - Cessna 177 SERIES Service Manual

NOTES
1 Weighted adjustable stand attaches to tie-down ring.
Wing jack points are aft of the aircraft center-of-gravity.
This causes the aircraft to be nose-
heavy when on jacks. Place additional weights (shot bags or sand bags) on the weighted tail
stand to hold the tail down. In addition, the base of adjustable stand (SE-767) is to be filled
with concrete for additional weight as a safety factor.
2 On tubular gear aircraft, the only fairing that requires removal is the one common to the fuselage and
the tube gear fairing. This requires the removal of (7) screws.
The jack pad is then inserted on the
tube in the area between the fuselage and the upper end of the tube fairing, then jack the aircraft as re-
quired. The jack pad may be used only to raise one main wheel.
Do not use brake castings as jack
points.
3. Items (3), (4), (5) and (6) are available from the Cessna Service Parts Center.
JACKING INFORMATION
1. Place wing jack under main spar of the wing just outboard of main wheel.
Pad at top of,
jack should be placed at junction of main wing spar and wing rib.
2. Raise aircraft tail and attach tail stand to tie-down fitting. BE SURE the tail stand weighs
enough to keep the tail down under all conditions and that it is strong enough to support any
weight that may be placed upon it.
3. Operate jacks evenly until desired height is reached.
4. The individual strut jack pad may be used to raise only one main wheel at a time.
Dis-
connect strut-to-fuselage fairing to attach strut jack pad to strut. DO NOT use brake
casting as a jack point.
5. The nose may be raised by lowering and tying down the tail.
6. The aircraft may be hoisted as outlined in paragraph 2-3.
LEVELING THE AIRCRAFT
Longitudinal leveling of the aircraft is accomplished by removing the two screws
in the tailcone (shown in figure 2-2 at "A") and installing bolts in the jig-located
nutplates, then placing a level across the bolts. Also refer to paragraph 2-5.
A level placed across the front seat rails at corresponding points is used to level the
aircraft laterally.
