TUSTIN, CA, USA

Aircraft #1

N5353Y

PIPER PA-23-250

Analysis

THE PLT'S MECHANIC PERFORMED A PRE-PURCHASE INSPECTION OF THE ACFT. NO MALFUNCTIONS WERE DETECTED WITH THE FUEL SYSTEM, & THE MECHANIC INFORMED THE PLT THAT THE ACFT WAS OVERALL 'IN GOOD CONDITION.' LATER IN THE DAY THE PLT PURCHASED THE ACFT, & AFTER OBSERVING THAT ITS MAIN FUEL TANKS WERE VIRTUALLY FULL HE TOOK OFF. ACCORDING TO THE PLT, WITH FULL MAIN FUEL TANKS THE ACFT'S ENDURANCE WOULD BE 2.8 HRS. DURING THE FLIGHT THE PLT OBSERVED THE MAIN TANKS' FUEL GAUGES, & THEY INDICATED THE FUEL LEVEL TO BE AT 1/2 & 1/4 CAPACITY. 10 MIN LATER BOTH ENGINES LOST ALL POWER, & PLT MADE A FORCED LDG IN AN UNDERLYING SOFT FIELD. EXAM OF THE FUEL TANKS' BLADDERS REVEALED THAT SOME OF THE SNAP FASTENERS DESIGNED TO SECURE THE TOPS OF THE BLADDERS WERE EXCESSIVELY WEATHER CHECKED & HAD SHRUNK.
