Narrative:

During a local training flight at an uncontrolled field (aeg) the training aircraft lost engine power due to fuel mismgmnt. The aircraft was burning fuel off its right fuel tank which according to fuel gauge indications contained nearly 1/4 tank of fuel. Preflight inspection of the fuel levels confirmed sufficient fuel for the hour long flight. Training was being conducted in the traffic pattern and upon reaching the downwind leg of the 5TH circuit in the pattern; the engine sputtered and lost power. The instructor (reporter) took controls of the aircraft and immediately began a gliding turn for runway 22. There was a mooney in the flare on the same runway. The instructor pilot requested that the mooney go around and he complied. The emergency aircraft landed uneventfully without engine power and coasted clear of runway 22 where it was retrieved by a tow vehicle. Upon inspection after landing; it appears that the right fuel tank was run dry and that return fuel from the right tank was pumped into the left tank and was unavailable to the engine in-flight. Future preflight measures will be extra thorough in determining the accurate fuel level of the aircraft to ensure fuel will be available to the aircraft from both fuel tanks. The student's improper fuel management and the instructor pilot's failure to notice or correct the problem will also be addressed and remedied.

Title: BE23 ON LCL TRAINING FLT EXPERIENCED ENG FAILURE ON DOWNWIND; POST INSPECTION REVEALED FUEL STARVATION.

Narrative: DURING A LCL TRAINING FLT AT AN UNCTLED FIELD (AEG) THE TRAINING ACFT LOST ENG PWR DUE TO FUEL MISMGMNT. THE ACFT WAS BURNING FUEL OFF ITS R FUEL TANK WHICH ACCORDING TO FUEL GAUGE INDICATIONS CONTAINED NEARLY 1/4 TANK OF FUEL. PREFLT INSPECTION OF THE FUEL LEVELS CONFIRMED SUFFICIENT FUEL FOR THE HR LONG FLT. TRAINING WAS BEING CONDUCTED IN THE TFC PATTERN AND UPON REACHING THE DOWNWIND LEG OF THE 5TH CIRCUIT IN THE PATTERN; THE ENG SPUTTERED AND LOST PWR. THE INSTRUCTOR (RPTR) TOOK CTLS OF THE ACFT AND IMMEDIATELY BEGAN A GLIDING TURN FOR RWY 22. THERE WAS A MOONEY IN THE FLARE ON THE SAME RWY. THE INSTRUCTOR PLT REQUESTED THAT THE MOONEY GO AROUND AND HE COMPLIED. THE EMER ACFT LANDED UNEVENTFULLY WITHOUT ENG PWR AND COASTED CLR OF RWY 22 WHERE IT WAS RETRIEVED BY A TOW VEHICLE. UPON INSPECTION AFTER LNDG; IT APPEARS THAT THE R FUEL TANK WAS RUN DRY AND THAT RETURN FUEL FROM THE R TANK WAS PUMPED INTO THE L TANK AND WAS UNAVAILABLE TO THE ENG INFLT. FUTURE PREFLT MEASURES WILL BE EXTRA THOROUGH IN DETERMINING THE ACCURATE FUEL LEVEL OF THE ACFT TO ENSURE FUEL WILL BE AVAILABLE TO THE ACFT FROM BOTH FUEL TANKS. THE STUDENT'S IMPROPER FUEL MGMNT AND THE INSTRUCTOR PLT'S FAILURE TO NOTICE OR CORRECT THE PROB WILL ALSO BE ADDRESSED AND REMEDIED.
