Logbook Entry
After any of the above work is accomplished, appropriate logbook
entries must be made. Logbook entries should contain:
1. The date the work was accomplished.
2. Description of the work.
3. Number of hours on the aircraft.
4. The certificate number of pilot performing the work.
5. Signature of the individual doing the work.
Logbooks should be complete and up to date. Good records reduce
maintenance cost by giving the mechanic information about what has
or has not been accomplished.

Ground Handling
Application of External Power
A ground service receptacle, located just aft of the cowl on the left side
of the airplane, permits the use of an external power source for cold
weather starting and maintenance procedures.
• WARNING •
If external power will be used to start engine, keep yourself,
others, and power unit cables well clear of the propeller
rotation plane.
To apply external power to the airplane:
• Caution •
Do not use external power to start the airplane with a ‘dead’
battery or to charge a dead or weak battery in the airplane.
The battery must be removed from the airplane and battery
maintenance performed in accordance with the appropriate
Airplane Maintenance Manual procedures.
1. Ensure that external power source is regulated to 28 VDC.
2. Check BAT and AVIONICS power switches are ‘off.’
3. Plug external power source into the receptacle.
4. Set BAT switch to ON. 28 VDC from the external power unit will
energize the main distribution and essential distribution buses.
The airplane may now be started or electrical equipment
operated.
5. If avionics are required, set AVIONICS power switch ON.
• Caution •
If maintenance on avionics systems is to be performed, it is
recommended that external power be used. Do not start or
crank the engine with the AVIONICS power switch ‘on.’
To remove external power from airplane:
1. If battery power is no longer required, set BAT switch ‘off.’
2. Pull external power source plug.

Towing
The airplane may be moved on the ground by the use of the nose
wheel steering bar that is stowed in the rear baggage compartment or
by power equipment that will not damage or excessively strain the
nose gear assembly. The steering bar is engaged by inserting it into
lugs just forward of the nose wheel axle.
• Caution •
While pushing the aircraft backward, the tow bar must be
installed to keep the nose wheel from turning abruptly.
Do not use the vertical or horizontal control surfaces or
stabilizers to move the airplane. If a tow bar is not available,
use the wing roots as push points.
Do not push or pull on control surfaces or propeller to
maneuver the airplane.
Do not tow the airplane when the main gear is obstructed with
mud or snow.
If the airplane is to be towed by vehicle, do not turn the nose
wheel more than 90 degrees either side of center or structural
damage to the nose gear could result.
1. Refer to Airplane Three View (Section 1, Figure 1-1) and Turning
Radius (Section 1, Figure 1-2) or clearances. Be especially
cognizant of hangar door clearances.
2. Insert tow bar into the lugs just forward of the nose wheel axle.
3. Release parking brake and remove chocks
4. Move airplane to desired location.
5. Install chocks
6. Remove tow bar.
To obtain a minimum radius turn during ground handling, the airplane
may be rotated around either main landing gear by pressing down on a
fuselage just forward of the horizontal stabilizer to raise the nosewheel
off the ground.
