action of the nose strut does not cause excessive vertical movement "I
the tail and the resulting contact with low hangar doors or structure,
A flat nose tire or deflated strut will also increase tail height.
PARKING
When parking the airplane, head into the wind and set the parking
brakes. Do not set the parking brakes during cold weather when ac-
cumulated moisture may freeze the brakes, or when the brakes are
overheated. Install the control wheel lock and chock the wheels. In
severe weather and high wind conditions, tie the airplane down as out
lined in the following paragraph.
TIE-DOWN
Proper tie-down procedure is the best precaution against damage to
the parked airplane by gusty or strong winds. To tie-down the ai rpl am-
securely, proceed as follows:
(1) Set the parking brake and install the control wheel lock.
(2) Install a surface control lock over the fin and rudder.
(3) Tie sufficiently strong ropes or chains (700 pounds tensile
strength) to the wing, tail, and nose tie-down fittings and secure
each rope to a ramp tie-down.
(4) Install a pitot tube cover.
JACKING
When a requirement exists to jack the entire airplane off the
ground, or when wing jack points are used in the jacking operation,
refer to the Service Manual for specific procedures and equipment re-
quired.
Individual main gear may be jacked by using the jack pad which is
incorporated in the main landing gear strut step bracket. When using
the individual gear strut jack pad, flexibility of the gear strut will
cause the main wheel to slide inboard as the wheel is raised, tilting the
jack. The jack must then be lowered for a second jacking operation.
Do not jack both main wheels simultaneously using the individual
main gear jack pads.
If nose gear maintenance is required, the nose wheel may be raised
off the ground by pressing down on a tailcone bulkhead, just forward of
the horizontal stabilizer, and allowing the tail to rest on the tail tie-
down ring.
