## Discrepancy

(CAN) LOWER LT MOUNTING / MATING SURFACE INCORRECTLY MACHINED. SURFACE WAS MACHINED CYLINDRICALLY INSTEAD OF SPHERICAL CONVEX. IF INSTALLED THE MATING SURFACES WOULD NOT MATCH CAUSING STRESS AND POSSIBLE FAILURE OF THE MOUNT. CONCERNED THAT MORE WERE PRODUCED AND INSTALLED FROM THE SAME BATCH.
