## Discrepancy

FIRST PUMP REPLACED APPEARED TO HAVE OVER 800 HRS IN SERVICE.  REPLACED WITH NEW AIRBORNE PUMP 10/95.  IT LASTED 35.9 HRS. REPLACED AGAIN 12/95 LASTED 31.9 HRS.  SYSTEM CHECKED WITH AIRBORNE 343 TEST KIT.  PUMP LASTED 16.0 HRS.  REPLACED AND SYSTEM CHECKED, LASTED 23.3 HRS.  LAST 3 PUMPS SENT DIRECTLY TO AIRBORNE FOR ANALYSIS.  ALL PUMPS WARRANTIED, BUT HAVE BEEN UNABLE TO DETERMINE A CAUSE FOR CONTINUED FAILURES.  HAVE DISCUSSED PROBLEM WITH BEECH, CONTINENTAL, AND AIRBORNE.  AT THIS POINT, SUSPECT FAULTY PUMPS.
