## Discrepancy

DURING AN ANNUAL INSPECTION, NOTED 2 OF 4 MAIN GEAR RETRACT BRACE, PIVOT PIN, RETAINER SCREWS WERE ABLE TO ROTATE. REMOVED AND FOUND THE THREADS WORN FROM THE SHEAR ACTION OF THE PIN. CORRECTED PROBLEM BY INSTALLING NEW ANS525R-832R8 SCREWS WHICH HAVE A SHOULDER PROVIDING HIGHER SHEAR STRENGTH.
