LANDING GEAR, WHEELS AND BRAKES
MAIN LANDING GEAR
The main landing gear consists of two interchangeable spring steel gear assemblies
and two wheel and brake assemblies. A common center beam supports each gear half.
A dowel pin and clamp is used to hold the gear in place. The beam is mounted to left
and right plates, both of which are bolted to the lower forward fuselage frame. All
landing gear attach points should be carefully inspected for wear and damage during
landing gear checks. Always place the aircraft on jacks prior to performing any
maintenance procedures on the landing gear system.
MAIN LANDING GEAR REMOVAL
A. Jack aircraft as outlined in Section 2.
B. Remove fuselage skins as required.
C. Disconnect flexible hydraulic brake line and plug to prevent leakage and
contamination.
D. Remove the outboard saddle clamps from end-pieces.
E. Remove inboard clamp bolts.
**CAUTION**
The gear is extremely heavy and needs to be handled
accordingly to prevent personnel injury and/or damage to the
gear.
F. With the gear supported, lower it down off and away from the dowel pin. It may
be necessary to pry the gear apart.
CLEANING, INSPECTION AND REPAIR OF MAIN GEAR
A. Clean all parts with a suitable type cleaning solvent.
B. Inspect all bolts, bearings and bushings for excess wear, corrosion and damage.
C. Check all welds for cracks at fuselage support brackets.
D. Repair of the landing gear is limited to reconditioning of parts, such as replacing
components, bearings and bushings, smoothing out minor nicks and scratches
and repainting areas where paint has chipped or peeled.
TAIL LANDING GEAR
The tail landing gear consists of a 1-inch thick alloy steel spring, tail gear sub-assembly,
fork assembly and wheel assembly. The tail wheel is a locking type and is actuated
from the elevator bell crank by a cable. Centering springs align the tail wheel, and a pin
engages and locks the wheel in the trailing position. Pushing the control stick fully
forward disengages the locking pin and the wheel is free to caster for taxiing.
