8.5 ALTERATIONS OR REPAIRS
It is essential that the relevant airworthiness authorities are contacted prior to any alterations or
modications to the aircraft to ensure that continued airworthiness of the aircraft is not violated.
The certication standard of the GA8-TC 320 is the Federal Aviation Regulations (FAR) Part 23
at Amendment 54.
Alterations and repairs to the aircraft structure shall be carried out in accordance with the
GA8-TC 320 SERVICE MANUAL or in accordance with the FAA publication AC 43.13-1B&2B
or subsequent issues.
8.6 GROUND HANDLING
The aircraft can be easily manoeuvred on level ground by one person using a tow bar to push or
pull as required. Additional persons can assist by pushing or pulling on the main wing struts. The
aircraft should not be manoeuvred in any way by the empennage. In congested areas, wing
and/or tail walkers should be positioned to ensure adequate clearance from stationary objects.
8.7 PARKING
When possible park the aircraft into the anticipated wind and set the parking brakes. Do not set
the parking brakes during cold weather when accumulated moisture may freeze the brakes, or
when the brakes are very hot. Lock the controls using the lower portion of the pilot’s restraint
harness around the control column to secure it. Install wheel chocks when available. When
severe weather conditions or high winds are anticipated, the best precaution is to hangar the
aircraft. In less severe conditions, or when hangarage is not available the aircraft should be tied
down as outlined in the following paragraph.
8.8 TIE DOWN
The following procedure should be used to tie-down the aircraft:
a. Lock the ailerons and elevator as described above or by using suitable locally manufactured
external control surface locks.
b. Chock the wheels.
c. Attach a suitably strong (recommended 550 kg tensile strength) tie-down rope to the wing
tie-down rings at approximately 45 degrees to the ground. Leave sufcient slack to avoid
damage due to rope shrinkage that may occur when a moist rope dries out.
d. Attach a suitably strong (recommended 550 kg tensile strength) tie down rope to the
tail tie-down at approximately 45 degrees to the ground. Leave sufcient slack to avoid
damage due to rope shrinkage that may occur when a moist rope dries out.
