THE ACFT HAD NOT BEEN FLOWN FOR SVRL YEARS & WAS ON A FLT TO FERRY IT TO ANOTHER LOCATION. WHILE CRUISING AT 7500', THE PLT DECIDED TO START USING AUX FUEL.

FUEL SAMPLES WERE TAKEN & A VISUAL EXAM REVEALED OBVIOUS CONTAMINATION & DISCOLORATION. THE ACFT HAD BEEN GIVEN AN ANNUAL INSPN JUST BEFORE THE FLT.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number LAX87LA265.
