What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.4)The aircraft (P-38) had been topped off with full reserve & main fuel tanks (44 us gal/engine reserve tanks & 72 gal/engine main tanks). The pilot took off with about 20 minutes fuel having been already consumed. Operating with another P-38 within the airport area, the 2 aircraft flew about 20 to 25 minutes each. The fuel consumption was reported nominally at 60 gallons/hour/engine (1 gal/minute). With 44 gallons of fuel in each reserve tank for the duration of both flights, the engines would have exhausted all available fuel in each reserve tank after about 44 minutes. Both fuel selectors were found on the reserve setting at the site. No mechanical malfunction was found with either propeller or engine. The flaps & landing gear were retracted. According to the pilot's manual (flight manual), if one engine fails below 120 mph (safe single-engine airspeed), the pilot is to 'close both throttles and land straight ahead.' The flight manual did not provide any information for aircraft minimum control speeds with the flaps fully retracted. Several witnesses reported the aircraft was slow while turning base. Since this was a single-seat aircraft, there was no provision for 'dual' ins tructional training in single-engine procedures or spin recovery. The pilot was reported to have flown 6 or 7 hours in another P-38, which included practice simulated single-engine maneuvers, but no actual in-flight shut down & feathering of an engine.
As the FAA filed it
(.4)THE AIRCRAFT (P-38) HAD BEEN TOPPED OFF WITH FULL RESERVE & MAIN FUEL TANKS (44 US GAL/ENGINE RESERVE TANKS & 72 GAL/ENGINE MAIN TANKS). THE PILOT TOOK OFF WITH ABOUT 20 MINUTES FUEL HAVING BEEN ALREADY CONSUMED. OPERATING WITH ANOTHER P-38 WITHIN THE AIRPORT AREA, THE 2 AIRCRAFT FLEW ABOUT 20 TO 25 MINUTES EACH. THE FUEL CONSUMPTION WAS REPORTED NOMINALLY AT 60 GALLONS/HOUR/ENGINE (1 GAL/MINUTE). WITH 44 GALLONS OF FUEL IN EACH RESERVE TANK FOR THE DURATION OF BOTH FLIGHTS, THE ENGINES WOULD HAVE EXHAUSTED ALL AVAILABLE FUEL IN EACH RESERVE TANK AFTER ABOUT 44 MINUTES. BOTH FUEL SELECTORS WERE FOUND ON THE RESERVE SETTING AT THE SITE. NO MECHANICAL MALFUNCTION WAS FOUND WITH EITHER PROPELLER OR ENGINE. THE FLAPS & LANDING GEAR WERE RETRACTED. ACCORDING TO THE PILOT'S MANUAL (FLIGHT MANUAL), IF ONE ENGINE FAILS BELOW 120 MPH (SAFE SINGLE-ENGINE AIRSPEED), THE PILOT IS TO 'CLOSE BOTH THROTTLES AND LAND STRAIGHT AHEAD.' THE FLIGHT MANUAL DID NOT PROVIDE ANY INFORMATION FOR AIRCRAFT MINIMUM CONTROL SPEEDS WITH THE FLAPS FULLY RETRACTED. SEVERAL WITNESSES REPORTED THE AIRCRAFT WAS SLOW WHILE TURNING BASE. SINCE THIS WAS A SINGLE-SEAT AIRCRAFT, THERE WAS NO PROVISION FOR 'DUAL' INS TRUCTIONAL TRAINING IN SINGLE-ENGINE PROCEDURES OR SPIN RECOVERY. THE PILOT WAS REPORTED TO HAVE FLOWN 6 OR 7 HOURS IN ANOTHER P-38, WHICH INCLUDED PRACTICE SIMULATED SINGLE-ENGINE MANEUVERS, BUT NO ACTUAL IN-FLIGHT SHUT DOWN & FEATHERING OF AN ENGINE.
