MANUAL LANDING GEAR
EXTENSION
A hand pump handle, placarded “LANDING
GEAR ALTERNATE EXTENSION” (Figure
14-15), is located on the floor between the
pilot’s seat and the pedestal. The pump is lo-
cated under the floor, below the handle, and
is used when emergency extension of the
gear is required.
To engage the system, pull the LANDING

LDG GEAR CONTROL switch handle on the
pilot’s sub-panel, and ensure that the LDG
GEAR CONTROL handle is in the DN po-
sition. Remove the pump handle from the se-
curing clip, and pump the handle up and down
until the green NOSE-L-R gear-down indi-
cator lights illuminate and further resistance
is felt. Place the handle in the fully down po-
sition and secure in the retaining clip.

to ensure that the gear is down and
locked. Do not stow pump handle.
The landing gear cannot be manually
retracted in flight.
