MAINTENANCE PRACTICES

Tiedown rotor blades, whenever
CAUTION
helicopter is parked, to prevent
rotor damage from blade flapping as a result
of air turbulence from other aircraft or wind
gusts. The maximum blade tie down load is
when the blade tip just begins to deflect
downward.
(5). Secure main rotor blades with blade
tiedowns (1), if helicopter is parked in
an area subject to turbulence (Ref.
Section 10-20-00).
(6). Ensure all switches are in the OFF
position and external power is discon­
nected.
(7). Install engine area cover (4), pitot cover
(2) and upper deck cover (3) (Ref.
Section 10-20-00).
(8). Close and secure all doors, windows
and access panels (Ref. Section
06-00-00).
(9). Statically ground helicopter (Ref.
Section 10-10-00).
B. Turbulent Conditions − Helicopter
Parking
Procedures for parking the MD Explorer in
turbulent conditions are for winds in excess 45
knots.
(1). Park helicopter into the prevailing wind
and secure in accordance with normal
parking conditions.
(2). Statically ground helicopter (Ref.
Section 10-10-00).
2. Ground Service Connections
