N2428C Cessna 180 None

Probable cause & findings

IMPROPER INSTALLATION OF THE GEAR AXLE (USE OF IMPROPER BOLTS & THE WRONG NUMBER OF SHIMS), WHICH RESULTED IN A SUBSEQUENT FAILURE AND LOSS OF CONTROL DURING THE LANDING ROLL.

Factual narrative

THE PLT RPRTD THAT THE RGT BRAKE FAILED DURING A LANDING & THE ACFT VEERED TO THE LEFT. SUBSEQUENTLY, THE ACFT CAME TO REST WITH THE RIGHT MAIN WHEEL BROKEN OFF. AN INVESTIGATION REVEALED THAT THE WRONG TYPE OF BOLTS WERE USED TO MOUNT THE AXLE TO THE GEAR LEG. ALSO, 4 ALIGNMENT SHIMS WERE USED BETWEEN THE AXLE & GEAR LEG; THE CESSNA SVC MANUAL ALLOWED FOR THE USE OF ONLY 3 SHIMS.
