## Discrepancy

(CAN) LANDING GEAR SELECTOR HANDLE WOULD NOT RETURN TO NEUTRAL DURING ENGINE SHUTDOWN CHECK. NEW HYDRULIC PUMP INSTALLED AND LANDING GEAR SELECTOR CHECK FUNCTIONED NORMALLY. SUSPECT LOW VOLUME AND/OR PRESSURE OUTPUT FROM REMOVED PUMP. DEFECTIVE PART RETURNED TO MFR. FOR WARRANTY CONSIDERATION. HYDRAULIC PUMP DISCHARGE FILTER DID NOT SHOW ANY SIGN OF METAL CONTAMINATION.
