d. Level helicopter with forward cyclic at an altitude
sufficient to provide tail rotor clearance.
e. As helicopter settles toward the ground, apply up
collective to cushion landing.
f. Maximum recommended ground contact speed on
prepared surfaces is 35 MPH. Reduce speed on rough
surfaces.
CAUTION
Avoid rapid lowering of collective or use of aft
cyclic after ground contact or during ground slide.
4. Engine Failure – At Hover in Ground Effect
Engine failure at a hover is indicated by a sudden yawing
of the helicopter to the left. Avoid sideward or rearward
movement after engine failure and proceed as follows:
a. Apply right pedal to prevent yawing and align skids in
direction of motion.
b. DO NOT reduce collective.
c. As helicopter settles to the ground, apply up collective
to cushion landing.
3-6. Low Engine Oil Pressure
1. Low Oil Pressure and Normal Oil Temperature
If low oil pressure is accompanied by normal oil
temperature there is a possibility the oil pressure gauge
or relief valve is malfunctioning. This is not necessarily
cause for an immediate precautionary landing. Proceed
as follows:
a. Land at nearest suitable landing area.
b. Inspect for and correct this source of trouble before
continuing flight.
