CAUTION:_______REMOVE THE STABILIZING JACK FROM BELOW THE AIRPLANE. THIS WILL PREVENT DAMAGE TO THE SKIN AND THE FRAME.
(e)
Lower the stabilizing jack at jack point D (Fig. 201).
NOTE: Keep 1 inch clearance between the locknut and collar.
____
(f) Put a person at each jack location.
CAUTION: DO NOT LOWER THE WING JACKS A AND B BEFORE THE TAIL JACK C
_______ OR THE NOSE GEAR WILL TOUCH FIRST. THIS WILL OVERLOAD THE TAIL JACK POINT C.
(g) Lower the jacks at jack points A, B, and C evenly and at the same time.
NOTE: Use the plumb bob in the right wheel well to keep the
____ airplane level. Always keep a 1 inch clearance between the locknut and the jack collar. If nose and main gear oleo lock assemblies are not installed, be sure that there are no obstructions in front of the main gear wheels and that parking brakes are not set. Because of a 1.85 degree cant of the shock strut, the wheels will move approximately 0.55 inch forward because of oleo retraction.
You can remove a jack "hang up" condition. To do this, you lift and lower the jack until the ram is free. If the condition continues, lift and crib the airplane until you can replace the defective jack.
(h) Remove the jacks and the jack adapters.
