CAUTION!
Make sure nothing is under or above the airplane or floats when jacking the aircraft.
1.
Turn off fuel.
2.
Place weighted bags above the nose gear (approximately 100 lbs. on each float to start, more may be
added as needed).
3.
Position 1 person at each fore and aft of each float, and 3 people at the jacking location of one float.
4. Modify jack saddle of a 3 ton minimum jack by welding as shown in Figure 2-1.
FIGURE 2-1 JACK CRADLE RECOMMENDED MODIFICATION
(X = WIDTH OF CRADLE)
NOTE:
This is not required and Wipaire does not have the parts for modification. It is recommended a similar
modification be performed to the jack saddle to prevent the slippage of the cradle.
1. Center cradle on saddle and position so cradle is as far aft on the main keel as possible without interfering
with main gear as it decompresses as shown in Figure 2-2.
NOTE:
If desired to prevent possible cosmetic damage to float, use material to separate cradle and float.
FIGURE 2-2 JACKING LOCATION
1. Jack one side at a time, taking care to check the balance of the aircraft and adding more weight to the front
if needed.
2. Two people, both outboard, lift the fore and aft cradle stands up to the cradle as a 3rd person release the
pressure slowly, allowing the cradle and stands to gently contact the ground.
3.
Repeat previous procedure to the other float.
