Narrative:

I arrived at jnx airport at approximately XA30. I requested a top-off of the aircraft while preflight was being conducted. I was aware the aircraft had been sitting for some time, although a recent annual inspection was conducted. After preflight was complete, I started the aircraft and proceeded to the runup area. In the runup area, I established the microphone was not operating well. I returned to ramp and switched for another. I returned to runup and proceeded with runup and test of aircraft. Everything was ok, so I went on my way. A direct trip to sav, 248 NM away, at 2500 ft at 70% power. According to the flight plan calculations, the trip would have taken 2 hours 50 mins. At approximately 2 hours 30 mins into the flight, the engine started to lose power and an emergency landing was accomplished in a street in ridgeland, sc. No damage to persons or property or aircraft was caused. Aircraft was towed to ridgeland field and topped off with 24 gallons, clearly establishing I ran out of fuel. Once topped off at 3JI, I carefully inspected aircraft for leaks and mechanical problems and none were found. After a long runup and test takeoff run, I established the aircraft was safe for flight and departed for sav. From 3JI to sav, a 24 NM trip, and .4 hobbs, the aircraft was topped off again with 5 gallons, clearly showing a high fuel burn. I decided to spend the night and in the morning planned a 1 hour trip to jax and follow closely the fuel burn. After careful planning considering the wind, I again departed to jax, closely monitoring ground speed with my GPS. The trip to jax took 1.2 on hobbs and again, when aircraft was topped off, it took 11 gallons. According to the cruise performance chart, a burn for conditions was to be at 5.1 gallons per hour. I re-planned a trip for 1 hour to dab, completed flight planning, and departed for dab 85 NM away. At an average of 89 KTS ground speed, I arrived in dab in 1.0 hobbs. I topped off aircraft again and this time it took 9.4 gallons, clearly showing a high fuel burn. All along the trip I was in contact with the aircraft owner, an a&P and an inspection a&P.

Title: A C150 PLT REPEATEDLY PROVED, DURING 4 DIFFERENT FLTS OVER A PERIOD OF 2 DAYS, THAT HE DID NOT KNOW HOW TO PROPERLY AND SAFELY DEVELOP A FLT PLAN.

Narrative: I ARRIVED AT JNX ARPT AT APPROX XA30. I REQUESTED A TOP-OFF OF THE ACFT WHILE PREFLT WAS BEING CONDUCTED. I WAS AWARE THE ACFT HAD BEEN SITTING FOR SOME TIME, ALTHOUGH A RECENT ANNUAL INSPECTION WAS CONDUCTED. AFTER PREFLT WAS COMPLETE, I STARTED THE ACFT AND PROCEEDED TO THE RUNUP AREA. IN THE RUNUP AREA, I ESTABLISHED THE MIKE WAS NOT OPERATING WELL. I RETURNED TO RAMP AND SWITCHED FOR ANOTHER. I RETURNED TO RUNUP AND PROCEEDED WITH RUNUP AND TEST OF ACFT. EVERYTHING WAS OK, SO I WENT ON MY WAY. A DIRECT TRIP TO SAV, 248 NM AWAY, AT 2500 FT AT 70% PWR. ACCORDING TO THE FLT PLAN CALCULATIONS, THE TRIP WOULD HAVE TAKEN 2 HRS 50 MINS. AT APPROX 2 HRS 30 MINS INTO THE FLT, THE ENG STARTED TO LOSE PWR AND AN EMER LNDG WAS ACCOMPLISHED IN A STREET IN RIDGELAND, SC. NO DAMAGE TO PERSONS OR PROPERTY OR ACFT WAS CAUSED. ACFT WAS TOWED TO RIDGELAND FIELD AND TOPPED OFF WITH 24 GALLONS, CLRLY ESTABLISHING I RAN OUT OF FUEL. ONCE TOPPED OFF AT 3JI, I CAREFULLY INSPECTED ACFT FOR LEAKS AND MECHANICAL PROBS AND NONE WERE FOUND. AFTER A LONG RUNUP AND TEST TKOF RUN, I ESTABLISHED THE ACFT WAS SAFE FOR FLT AND DEPARTED FOR SAV. FROM 3JI TO SAV, A 24 NM TRIP, AND .4 HOBBS, THE ACFT WAS TOPPED OFF AGAIN WITH 5 GALLONS, CLRLY SHOWING A HIGH FUEL BURN. I DECIDED TO SPEND THE NIGHT AND IN THE MORNING PLANNED A 1 HR TRIP TO JAX AND FOLLOW CLOSELY THE FUEL BURN. AFTER CAREFUL PLANNING CONSIDERING THE WIND, I AGAIN DEPARTED TO JAX, CLOSELY MONITORING GND SPD WITH MY GPS. THE TRIP TO JAX TOOK 1.2 ON HOBBS AND AGAIN, WHEN ACFT WAS TOPPED OFF, IT TOOK 11 GALLONS. ACCORDING TO THE CRUISE PERFORMANCE CHART, A BURN FOR CONDITIONS WAS TO BE AT 5.1 GALLONS PER HR. I RE-PLANNED A TRIP FOR 1 HR TO DAB, COMPLETED FLT PLANNING, AND DEPARTED FOR DAB 85 NM AWAY. AT AN AVERAGE OF 89 KTS GND SPD, I ARRIVED IN DAB IN 1.0 HOBBS. I TOPPED OFF ACFT AGAIN AND THIS TIME IT TOOK 9.4 GALLONS, CLRLY SHOWING A HIGH FUEL BURN. ALL ALONG THE TRIP I WAS IN CONTACT WITH THE ACFT OWNER, AN A&P AND AN INSPECTION A&P.
