Landing Gear Axle Corrosion
Most Westwind 1124 / 1124A operators are aware that the main landing gear axles are susceptible to internal corrosion. Moisture is the main contributor to this condition, as it becomes trapped in the bore of the axle. It can enter from the anti-skid transducer conduit or from the end plug of the axle itself. Corrosion within the limits set forth in the Westwind Maintenance Manual Chapter 32-10-01 can be removed. Unfortunately, pitting beyond the maintenance manual limits is cause for axle rejection. Be sure your maintenance facility properly coats the axle bore with DC4 and seals the axle cap and top of the anti-skid transducer conduit with sealer. Attention to this detail may prevent axle replacement.

Proper MLG Alignment to Reduce Cost/Time
Edge wear on a Westwind 1124/1124A main landing gear tire is a common occurrence that can usually be corrected with proper gear alignment. If left unchecked, it can lead to costly strut repairs. If your aircraft is experiencing main landing gear tire wear problems, ask your maintenance facility to check the gear for proper alignment. This can be done during routine visits or scheduled inspections. It normally requires shimming the torque links, servicing the struts, and checking tire pressures.The procedure for aligning the gear is not complicated, but it does require a little time and patience. Pay particular attention to the boss on the upper and lower strut legs where the torque links attach. These holes become elongated and can be repaired if found early enough. Any worn parts found should be repaired or replaced.The landing gear is an important part of any aircraft. Maintaining proper gear alignment can be satisfying to both the operator and technician by reducing costs and downtime.

Checking Main Landing Gear Wheel
When checking the main landing gear wheel assembly on the Westwind 1124/1124A during a tire change or other routine maintenance, look closely at the brake key way liners and reinforcing ring. Attention to these areas will contribute to the longevity of the wheel and many trouble-free landings.The steel key way liners are designed to keep the brake tangs from contacting the wheel assembly. A worn liner can allow the tang to damage the wheel, increasing the chance of cracks. This wear is most evident in the corner of the key way nearest the center of the wheel. Refer to the ABSC Wheel Component Maintenance Manual(CMM) for the allowable wear limits. During this check, also ensure the reinforcing ring is securely attached to the key ways. The rivets holding the reinforcing ring can appear to be intact when, in fact, they are broken. If replacement of a fastener is required, don’t forget about the washer between the ring and flange. An oversized rivet may be used within the guidelines of the CMM to repair loose or elongated holes.
