In event nose position tiedown is considered to
be of doubtful security due to existing soil
condition, drive additional anchor rods at nose
tiedown position. Place padded work stand or
other suitable support under the aft fuselage
tiedown position and secure.
Place control surfaces in locked position and
trim tab controls in neutral position. Place
wing flaps in up position.
The requirements for dust excluders, protective
covers, and taping of openings will be left to the
discretion of the responsible maintenance
officer or the pilot of the transient aircraft (fig.
Secure propellers to prevent windmilling (fig.
During typhoon or hurricane wind conditions,
mooring security can be further increased by
placing sandbags along the wings to break up
the aerodynamic flow of air over the wing,
thereby reducing the lift being applied ' against
the mooring by the wind. The storm appears to
pass two times, each time with a different wind
direction. This will necessitate turning the
aircraft after the first passing.
After high winds, inspect aircraft for visible
signs of structural damage and for evidence of
damage from flying objects. Service nose shock
strut and reconnect battery.
