ALTERATIONS
If the owner of an aircraft desires to have it modified,
FAA
approval must be obtained prior to
modification to insure that the proposed alteration does not violate the airworthiness of the
aircraft. Any major alteration to the basic aihe or any aircraft system requires a STC and must
be accomplished by licensed personnel.
GROUND HANDLING
1.)
Towing:
The airplane is most safely and easily moved on the ground by use of the nose wheel steering
bar that is stowed in the baggage compartment. Towing lugs are incorporated as part of the
nose gear fork. The three-view drawing in Section
1
of this Handbook shows the minimum
clearances needed to hanger the airplane.
**
CAUTION
**
When towing with power equipment, do not exceed the nose gear steering angle of
20
degrees
either side of center or structural damage will result. To insure adequate propeller ground
clearance, always obsewe recommended strut servicing procedures and tire inflation pressures.
2.)
Parking and Mooring:
When parking the airplane, face it into the wind if possible and set the parking brake. Care
should be exercised when setting parking brakes that are overheated or in cold weather when
accumulated moisture can freeze the brake.
The airplane should be moored for immovability, security and protection. The following
procedure is recommended.
A,)
Block the wheels, fore and aft.
B.)
Secure tie-down ropes to the wing tie-down rings and tail skid at approximately
45
degree angles to the ground. Use bowline or square knots; do not use slip knots.
C.)
Immobilize ailerons and stabilator.
D.)
Retract the wing flaps.
E.)
Close fresh air inlets.
F.)
Release the parking brake.
G.)
Install a pitot head cover.
H.)
Cabin, baggage compartment and storm window should be locked when the airplane is
unattended
3.)
Jacking:
When jacking the airplane for landing-gear service or any other purpose, two hydraulic jacks
and a tail stand should be used. The airplane is equipped with a jacking pad located on each
main spar just outboard of the main landing gear. Approximately
300
to
400
pounds of ballast
should be placed on the base of the tail stand before jacking the airplane.
