7--10--00 -- JACKING
When it is necessary to raise the aircraft off the ground:
-- CAUTION --
Do not raise the aircraft on jacks, out of doors,
when wind velocity is over 10 MPH. Jacks should
be on hard surface.
1. Install wing jack points (2) (Mooney P/N
010000--000) in tiedown mounting holes outboard of
each main landing gear. Install Nose Landing Gear jack
point (1) (jackpoint, Mooney P/N 010000--000) into re-
ceptacle (located under the cowling at Fuselage Sta-
tion --5.51) -- Refer to Figure 7--1.
2. Use standard aircraft jacks at both wing hoist
points (wing tiedown eyebolt receptacles) outboard of
the main landing gears and at the nose landing gear
(extended shaft) jack point. While holding wing jack
points in place, raise jack to firmly contact jack point.
3. To raise engine, remove top cowling and support
the engine using an “A” Frame with chain hoist or hy-
draulic “Cherry Picker” and hook into the engine lifting
hook (LYCOMING engine) mounted on top of engine or
front and rear engine lift hooks (CONTINENTAL en-
gine) (Refer to Figure 7--1).
4. Raise aircraft, keeping wings as nearly level as
possible.
5. Secure safety locks on each jack.
-- WARNING --
Do not use propeller jacks to lift aircraft.
-- CAUTION --
When lowering aircraft on jacks, bleed off pres-
sure on all jacks simultaneously and evenly to
keep aircraft level as it is being lowered.
-- CAUTION --
Individual wheels may be raised without raising
entire aircraft. Wheels not being raised should be
chocked fore and aft.
NOTE:
It is not recommended to use tail--tie down fitting
during jacking process to lift nose wheel off
ground.
-- CAUTION --
Do not leave aircraft on jacks for extended peri-
ods while a tailstand is in place. The wing jack(s)
may bleed down and put excessive loads on the
front jack point and tailcone.
