Common Landing Gear Issues
Faults we diagnose & resolve
From hydraulic leaks to structural fatigue, our team understands the failure patterns intimately.
Hydraulic Leaks
Causes: seal degradation, scored cylinders, corrosion pits, over-pressure events.
Resolution: seal replacement, cylinder grinding & re-plating, leak-down testing.
Corrosion & Pitting
Causes: environmental exposure, salt-air operation, plating breakdown.
Resolution: strip & reprocess plating, dimensional restoration via HVOF or hard chrome, salt-spray verification.
Shock Absorber Malfunctions
Causes: nitrogen pre-charge loss, oil contamination, worn metering pins.
Resolution: servicing, metering pin grinding, recoil valve overhaul.
Structural Fatigue & Cracks
Causes: cyclic loading, hard landings, overstress events.
Resolution: FPI / MPI inspection, DER-approved repairs, shot peening for fatigue life extension.
Shimmy & Wheel Vibration
Causes: shimmy damper wear, torque-link play, tire imbalance.
Resolution: damper rebuild, link bushing replacement, dynamic balancing.
Retraction / Extension Faults
Causes: sequencing-valve wear, uplock failure, actuator internal leakage.
Resolution: functional cycling, sequencing valve overhaul, actuator rebuild & test.
