6. PARKING AND MOORING
Parking (Ref. Figure 7−3):
To prevent rotor damage from blade flapping (droop stop pound-
ing) as a result of air turbulence from other aircraft landing, taking
off or taxiing or sudden wind gusts, rotor blades should be secured
whenever helicopter is parked.
Locate helicopter slightly more than blade clearance from nearby objects on
most level ground available.
Apply friction to lock cyclic and collective sticks so that friction control
knobs are positioned as follows: neutral for cyclic stick an full down for col-
lective stick.
Secure main rotor blades as follows.
Turn blades until one blade is directly above tailboom (Ref. Figure 7−3).
Install blade socks on all blades.
Secure blade sock tiedown cord for blade located above tailboom to tailboom.
Secure other blade sock tiedown cords to fuselage jack fittings or cabin
steps.
When securing blade sock tiedown cords, take up slack, but do not
apply excessive bending loads on blades.
Mooring (Ref. Figure 7−3):
Whenever severe storm conditions or wind velocities higher than 40 knots
are forecast, helicopter should be hangared or evacuated to safer area.
Park helicopter and remove main rotor blades.
Install pitot tube cover.
Fill fuel tank (if possible).
Apply friction to lock cyclic and collective sticks.
Secure helicopter to ground by attaching restraining lines (cable or rope) be-
tween jack fittings and stakes or ground anchors.
Install air inlet fairing cover on air inlet front fairing.
Install engine exhaust cover on exhaust tailpipe.
