A CESSNA 206 RAN A TANK DRY RIGHT AFTER TKOF.

Narrative

AS A STUDENT ON TRAINING FLT FROM CHARLOTTE; THE ENG OF A 206 LOST PwR. THE INSTRUCTOR LANDED THE PLANE SAFELY ON THE RWY. ON INSPECTION; THE L GAS CAP WAS FOUND TO BE BACKWARDS AND THE TANK REQUIRED 30 GALS IN A 31.5 CAP TANK. THE INSTRUCTOR HAD CHKED THE FUEL ON THE FIRST FLT AND FOUND THE L TANK TO INDICATE 1/2 FULL. THE R TANK WAS FULL. HE FLEW APPROX 35 MINS ON THE R; AND 20 MINS ON THE L. IT IS MY PRACTICE; AS OWNER; TO ALWAYS FILL BOTH TANKS BEFORE HANGARING. ON QUESTIONING; IT WAS FOUND THAT A LICENSED PLT WITH PERMISSION FLEW THE PLANE LESS THAN AN HR AND DID NOT REFUEL BEFORE HANGARING. ON PREFLT IN CHARLOTTE; THE L TANK GAUGE DID NOT INDICATE EMPTY; BUT LESS THAN 1/2. IT APPEARS THAT THE FUEL MAY HAVE BEEN SUCKED OUT ON THE TKOF IF THE CAP WAS NOT SEALED PROPERLY. CONTRIBUTING FACTORS: FAILURE TO CHK THE CAP AND CAPACITY VISUALLY IN EACH TANK. NOT REFUELING PRIOR TO HANGARING THE ACFT. CORRECTIVE ACTION: ALWAYS VISUALLY VERIFY FUEL IN ACFT AND CHK FUEL CAPS. SUPPLEMENTAL INFO FROM ACN 266186: CLRED FOR TKOF ON RWY 5. WHEN WE TURNED L 270 DEG; ENG LOST PWR. I TOOK OVER THE CTLS AND CONTINUED L TURN TO LINE US UP WITH RWY 18L FOR EMER LNDG. TWR CLRED US TO LAND ANY RWY. DURING DSCNT; ENG CAME BACK ON. AFTER ENG SHUTDOWN; WE INSPECTED FUEL TANKS; AND WE SAW THAT L FUEL TANK WAS EMPTY. PLT ERROR TO DOUBLE-CHK IT. MY STUDENT PREFLTED THE PLANE BEFORE DEP. PLT ERROR ON BOTH MY SIDE AND MY STUDENT.
