Flight Crew Human Performance
Problem electrical failure. Flight planned from dickson, tn (M02) to scott-mid america (blv). WX not a factor (no ceiling. Slight haze, calm winds). Takeoff uneventful and first hour of flight normal, fuel gauges read about 3/4 tank. I checked fuel level and secured caps on preflight. Gradually, both tanks read down to half, then down to 1/4 full in about 15-20 min period. I decided to divert to paducah. I then started to try to call tower. No response. Gas gauges now read near zero (both of them). I tried to reach tower, then ground, then used guard frequency but no response on any frequency. I squawked 7600. With both gas needles at 'east' and touching red line, I decided to land. I overflew field and rocked wings and looked for light signals. I didn't see any, but decided to land anyway. Landing was uneventful. Fuel service showed tanks over half full (it took about 10 gals in a 24 gal tank). Attempts to restart engine after fuel servicing failed. There was not enough battery power to start engine. So, electrical failure led to communication out situation and false indications of no fuel.
Original NASA ASRS Text
Title: C152 PLT HAS TOTAL ELECTRIC FAILURE AND DIVERTS TO PAH.
Narrative: PROB ELECTRICAL FAILURE. FLT PLANNED FROM DICKSON, TN (M02) TO SCOTT-MID AMERICA (BLV). WX NOT A FACTOR (NO CEILING. SLIGHT HAZE, CALM WINDS). TKOF UNEVENTFUL AND FIRST HR OF FLT NORMAL, FUEL GAUGES READ ABOUT 3/4 TANK. I CHKED FUEL LEVEL AND SECURED CAPS ON PREFLT. GRADUALLY, BOTH TANKS READ DOWN TO HALF, THEN DOWN TO 1/4 FULL IN ABOUT 15-20 MIN PERIOD. I DECIDED TO DIVERT TO PADUCAH. I THEN STARTED TO TRY TO CALL TWR. NO RESPONSE. GAS GAUGES NOW READ NEAR ZERO (BOTH OF THEM). I TRIED TO REACH TWR, THEN GND, THEN USED GUARD FREQ BUT NO RESPONSE ON ANY FREQ. I SQUAWKED 7600. WITH BOTH GAS NEEDLES AT 'E' AND TOUCHING RED LINE, I DECIDED TO LAND. I OVERFLEW FIELD AND ROCKED WINGS AND LOOKED FOR LIGHT SIGNALS. I DIDN'T SEE ANY, BUT DECIDED TO LAND ANYWAY. LNDG WAS UNEVENTFUL. FUEL SVC SHOWED TANKS OVER HALF FULL (IT TOOK ABOUT 10 GALS IN A 24 GAL TANK). ATTEMPTS TO RESTART ENG AFTER FUEL SVCING FAILED. THERE WAS NOT ENOUGH BATTERY PWR TO START ENG. SO, ELECTRICAL FAILURE LED TO COM OUT SIT AND FALSE INDICATIONS OF NO FUEL.
