Adjust slotted screw head on center of switch to obtain
correct settings.
-- CAUTION --
The airspeed safety switch is designed to oper-
ate within a specified range during increasing
airspeed only. Due to hysteresis of the switch/di-
aphragm assembly switch MAY NOT deactivate
landing gear circuitry until approximately 49.5
KTS. This could allow landing gear to retract if
gear switch is inadvertently placed in UP position
during landing roll.
-- CAUTION --
During static system checks, pressure com-
pensation on the Pitot side of the switch dia-
phragm must be considered or switch diaphragm
may rupture.
NOTE:
Refer to proper electrical schematic when replac-
ing with switches from another manufacturer.

SPECTION
1. Aircraft with full fuel load and weight on landing
gear.
A. Main gear shock discs. (Fig. 32--28).
(1) Remove dust shield. Check gap between re-
taining collar (A) and top retaining plate (B). Allowable
gap is 0.00 to 0.85 inches.
(2) Replace discs when gap exceeds the toler-
ance. Use a shock disc replacement tool (C), P/N GSE
030038--501 (Green color), to remove and install main
gear shock discs. Use removable pad from tool as a
guide on top of shock link to align discs as they are be-
ing compressed.
(3) Careful application of the shock disc replace-
ment tool is recommended during replacement of main
gear shock disc to keep from damaging grease fittings.
NOTE:
Shock disc retention collar should be installed
with the chamfer facing down and forward.
(4) Main landing gear leg assembly axle is to be
located to provide a minimum of .23 inches clearance
between tire and any component inside wheel well. Al-
ternate collars, P/N 510049--001, --003, --005, --007,
--009 or --011 can be substituted for basic dash no. to
obtain this clearance. If any interference occurs be-
tween tire and other components during retract cycle,
next higher dash number collar moves axle approxi-
mately .50 inches aft.
B. Nose Gear Shock Discs. (See Fig. 32--29)
(1) Check for gap between retaining collar (D),
and top retaining plate (E). Top retaining plate must be
in contact with retaining collar.
(2) Replace shock discs if gap is found. Use
shock disc replacement tool (F), P/N GSE 030010, to
remove and install nose gear shock discs.
Use removable pad from tool as a guide on top of shock
link to align discs as they are being compressed.
