Narrative:

My IFR cross country flight originated from isp. A standard WX briefing was received about 30 mins before the flight. The flight was planned to be 3 hours en route with ric as the final destination. The airplane was then visually checked to have 2 full tanks of fuel, which is equivalent to 4 hours of flight time at the cruising altitude plus a little extra to facilitate run-up and climb. Upon receiving clearance prior to the flight, the entire flight plan was rerted via a different victor airway and VOR. The revised routing was accepted by me. At a little bit after 3 hours into the flight, I had determined that to reach my ric destination the flight would continue on for another 30 mins. Hence, running into the required night IFR fuel reserves. Approximately 10 NM from ric, a 'direct ric clearance' had been amended to facilitate other landing traffic. Therefore, adding up extra flight time to get to the airport. The ATC controllers had been previously informed about the fuel situation. At about less than 5 NM to ric, an emergency situation had been declared by me due to the engine running rough for a short period of time. However, power was regained and a safe power-on landing was made. I was able to taxi on my own power to the FBO ramp escorted by emergency service vehicles.

Title: C152 PLT RAN SHORT OF FUEL AND DECLARED AN EMER AFTER EXTENSIVE ATC FLT PLAN REROUTING.

Narrative: MY IFR XCOUNTRY FLT ORIGINATED FROM ISP. A STANDARD WX BRIEFING WAS RECEIVED ABOUT 30 MINS BEFORE THE FLT. THE FLT WAS PLANNED TO BE 3 HRS ENRTE WITH RIC AS THE FINAL DEST. THE AIRPLANE WAS THEN VISUALLY CHKED TO HAVE 2 FULL TANKS OF FUEL, WHICH IS EQUIVALENT TO 4 HRS OF FLT TIME AT THE CRUISING ALT PLUS A LITTLE EXTRA TO FACILITATE RUN-UP AND CLB. UPON RECEIVING CLRNC PRIOR TO THE FLT, THE ENTIRE FLT PLAN WAS RERTED VIA A DIFFERENT VICTOR AIRWAY AND VOR. THE REVISED ROUTING WAS ACCEPTED BY ME. AT A LITTLE BIT AFTER 3 HRS INTO THE FLT, I HAD DETERMINED THAT TO REACH MY RIC DEST THE FLT WOULD CONTINUE ON FOR ANOTHER 30 MINS. HENCE, RUNNING INTO THE REQUIRED NIGHT IFR FUEL RESERVES. APPROX 10 NM FROM RIC, A 'DIRECT RIC CLRNC' HAD BEEN AMENDED TO FACILITATE OTHER LNDG TFC. THEREFORE, ADDING UP EXTRA FLT TIME TO GET TO THE ARPT. THE ATC CTLRS HAD BEEN PREVIOUSLY INFORMED ABOUT THE FUEL SIT. AT ABOUT LESS THAN 5 NM TO RIC, AN EMER SIT HAD BEEN DECLARED BY ME DUE TO THE ENG RUNNING ROUGH FOR A SHORT PERIOD OF TIME. HOWEVER, PWR WAS REGAINED AND A SAFE PWR-ON LNDG WAS MADE. I WAS ABLE TO TAXI ON MY OWN PWR TO THE FBO RAMP ESCORTED BY EMER SVC VEHICLES.
