Main Landing Gear Retraction Test

A. Prepare the aircraft for retraction test

B. No wind conditions

A. Jacks placed in proper position

B. Tail-plane raised to water line and tied to and sitting on a 40 lb weight. Do not put dead weight on the horizontal stabilizers.

C. Inspect the Emergency Gear Down Cables for condition, routing, alignment, security and tension.

D. Jacks should be extended simultaneously until gears are fully extended and wheels off floor by 2 inches.

E. Master Switch "ON" and gear lever placed in "UP" position

F. Listen for smooth operation and inspect for full retract of both gears

G. When both gears are retracted, "Up Switches" cancel system operation.

H. Inspect for gear door fit and security

I. Inspect for wheel fit and security

J. Inspect for leaks, chaffing, binding

K. Place gear lever in "Down Position"

L. Listen for smooth operation and watch downward movement for leaks, chaffing, or binding.

M. When both gears are extended, the "Down Switches" will cancel system operation.

N. Master Switch "Off". Inspect for leaks, chaffing, binding

Repeat "E" through "N" (total of two retractions)

Emergency Gear Extension Test (Observer Required)

With aircraft still on jacks, retract the landing gear (repeat "e" through "j")

Sit in the pilot’s seat, leave the Master Switch "ON"

Pull the circuit breaker for the landing gear and place the gear down lever in the "down" position.

Turn the Emergency Gear Down Handle clockwise about 52 turns until the landing gear is down and locked… the green light will come on if the system is rigged properly. Should the amber or red light stay on after the green, the landing gear is unsafe, regardless of the green light.

After confirming that the landing gear is safely down and locked, turn off the Master Switch and re-wind the Emergency Gear Down Handle approximately 52 turns in the counter clockwise direction. Do not use the aircraft hydraulic system function to retract the landing gear while this is being done.

NOTE: When returning the emergency crank handle to its full up position (counter clock-wise), do not force it thru a turn just to fit it into the resting slot. The handle must be replaced in position the last time it passes the position freely. Forcing it into position causes tension and side loads on the worm gear assembly which results in the pull-down cable jumping off the pulleys. Also, to obtain proper tension on the pull-down cable, simply adjust the turnbuckle in the pull down cable in order to have three fourths of a turn, and one half hand crank left after the second down-lock snaps into place (remember, this is a two person activity). Too much tension causes the landing gear to fall out before the cranking starts, and it can damage the pulleys in the wheel well area. Replacement of certain pulley brackets can mean removal of the outer wing panels and fuel cells. This information taken from page 22 of the blue Swift Maintenance and Information booklet.

Inspect the cables for condition, tension, alignment.

Visually inspect the Emergency Gear Down cable winding spool for "correct wrap" of the cables.

Flap Operation

F. Inspect both flap actuator rods for security and alignment

G. Inspect flap actuator (aft lower fuselage bay) for leaks, chaffing, binding.

H. Turn flap knob counter clockwise to "UP" position, and refer to "c" through "f" above.
