Narrative:

A private pilot with amel, CFI multi-engine rating and a nonrated private pilot on board an small aircraft twin, experienced an engine failure due to fuel starvation while on practice approach. The CFI observed the MEL student visually checking the fuel quantity on the preflight inspection and asked the student how much was in the tanks but did not personally inspect quantity. The student responded with 'up to the filler neck.' this sounded normal and the gauges in the cockpit seemed 'normal.' 2 hours and 10 mins into the flight the engine failure happened. The problem was quickly determined, the engine feathered, an emergency declared with approach control and a safe landing at the airport. Fuel quantity in the operative engine was dangerously low, only 15 mins left. This situation would have been avoided if: CFI had doubted student's rather genius response, student had 'seen' and not just 'looked.' CFI is guilty of complacency, some means of measuring fuel in tank was available.

Title: SMA TWIN EXPERIENCED FUEL EXHAUSTION STARVATION AND PERFORMS AN INFLT ENG SHUTDOWN AFTER EMER DECLARED FOR LNDG.

Narrative: A PRIVATE PLT WITH AMEL, CFI MULTI-ENG RATING AND A NONRATED PRIVATE PLT ON BOARD AN SMA TWIN, EXPERIENCED AN ENG FAILURE DUE TO FUEL STARVATION WHILE ON PRACTICE APCH. THE CFI OBSERVED THE MEL STUDENT VISUALLY CHKING THE FUEL QUANTITY ON THE PREFLT INSPECTION AND ASKED THE STUDENT HOW MUCH WAS IN THE TANKS BUT DID NOT PERSONALLY INSPECT QUANTITY. THE STUDENT RESPONDED WITH 'UP TO THE FILLER NECK.' THIS SOUNDED NORMAL AND THE GAUGES IN THE COCKPIT SEEMED 'NORMAL.' 2 HRS AND 10 MINS INTO THE FLT THE ENG FAILURE HAPPENED. THE PROB WAS QUICKLY DETERMINED, THE ENG FEATHERED, AN EMER DECLARED WITH APCH CTL AND A SAFE LNDG AT THE ARPT. FUEL QUANTITY IN THE OPERATIVE ENG WAS DANGEROUSLY LOW, ONLY 15 MINS LEFT. THIS SIT WOULD HAVE BEEN AVOIDED IF: CFI HAD DOUBTED STUDENT'S RATHER GENIUS RESPONSE, STUDENT HAD 'SEEN' AND NOT JUST 'LOOKED.' CFI IS GUILTY OF COMPLACENCY, SOME MEANS OF MEASURING FUEL IN TANK WAS AVAILABLE.
