GROUND HANDLING
(Continued)
JACKING
(Continued)
To assist in raising and holding the nosewheel off the ground, ground
anchors should be utilized at the tail tiedown point.
NOTE
Ensure that the nose will be held off the ground under all
conditions by means of suitable stands or supports under
weight supporting bulkheads near the nose of the airplane.
LEVELING
Longitudinal leveling of the airplane is accomplished by placing a level
on leveling screws located on the left side of the tailcone. Deflate the
nose tire and/or lower or raise the nose strut to properly center the
bubble in the level. Corresponding points on both upper door sills may
be used to level the airplane laterally.
FLYABLE STORAGE
Engines in airplanes that are flown every 30 days or less may not
achieve normal service life because of internal corrosion. Corrosion
occurs when moisture from the air and the products of combustion
combine to attack cylinder walls and bearing surfaces during periods
when the airplane is not flown.
The minimum recommended operating frequency for the engine is one
continuous flight hour (not counting taxi, takeoff and landing time) with
oil temperatures of 165°F to 200°F every 30 days or less (depending on
location and storage conditions). Airplanes operated close to oceans,
lakes, rivers and in humid regions are in greater need of engine
preservation than airplanes operated in arid regions. Appropriate
engine preservation procedures must be practiced by the owner or
operator of the airplane based on present environmental conditions and
the frequency of airplane activity.
NOTE
The engine manufacturer does not recommend pulling the
engine through by hand during storage periods.
