Narrative:

Aircraft was on a flight from fortuna airport, ca, to montgomery field, ca. Pilot departed at XA00 and the ETA at myf in san diego was XE00. Pilot was routinely switching between the left and right fuel tanks every 30 mins. At approximately 5-6 NM west of crq airport, ca, the engine began surging and losing power. The aircraft was in cruise flight and the pilot immediately followed engine-out procedures for cruise flight as per the cessna T210 operating manual. After not being able to regain full power the pilot decided the best course of action was to make an emergency landing at crq airport. The pilot decided to keep the aircraft light on once a safe landing was assured. A safe, uneventful landing was made and the engine power and mixture were cut off during landing rollout. The aircraft coasted safely off the runway and onto the parallel taxiway. The pilot requested it be towed to parking. The aircraft was determined to have 450.3 pounds of fuel available for flight at fortuna airport, ca, after subtracting 16.0 pounds for taxi and takeoff. It was determined, during preflight planning, that it would take 383.9 pounds for an almost direct flight to montgomery field, san diego, ca, at 11000 ft cruise altitude. The fuel remaining was to be 66.4 pounds upon arrival at myf airport. This allowed for the 45 min reserve for VFR night flight. The winds aloft for the route of flight varied between 310 degrees and 030 degrees. The aircraft had a tailwind the entire flight and the average ground speed was 170 KTS. The pilot refueled the aircraft at crq airport after a 1 hour rest period. The pilot then ran the engine for 20 mins to normalize the fuel injection system. The pilot determined the aircraft to be airworthy and continued the flight to montgomery field, san diego. The pilot suspects a possible flooded engine condition developed during emergency procedure.

Title: AN EXPERIENCED GA PLT, FLYING A CESSNA T210 EXPERIENCED A LOSS OF PWR AND MADE AN EMER LNDG AT CRQ.

Narrative: ACFT WAS ON A FLT FROM FORTUNA ARPT, CA, TO MONTGOMERY FIELD, CA. PLT DEPARTED AT XA00 AND THE ETA AT MYF IN SAN DIEGO WAS XE00. PLT WAS ROUTINELY SWITCHING BTWN THE L AND R FUEL TANKS EVERY 30 MINS. AT APPROX 5-6 NM W OF CRQ ARPT, CA, THE ENG BEGAN SURGING AND LOSING PWR. THE ACFT WAS IN CRUISE FLT AND THE PLT IMMEDIATELY FOLLOWED ENG-OUT PROCS FOR CRUISE FLT AS PER THE CESSNA T210 OPERATING MANUAL. AFTER NOT BEING ABLE TO REGAIN FULL PWR THE PLT DECIDED THE BEST COURSE OF ACTION WAS TO MAKE AN EMER LNDG AT CRQ ARPT. THE PLT DECIDED TO KEEP THE ACFT LIGHT ON ONCE A SAFE LNDG WAS ASSURED. A SAFE, UNEVENTFUL LNDG WAS MADE AND THE ENG PWR AND MIXTURE WERE CUT OFF DURING LNDG ROLLOUT. THE ACFT COASTED SAFELY OFF THE RWY AND ONTO THE PARALLEL TXWY. THE PLT REQUESTED IT BE TOWED TO PARKING. THE ACFT WAS DETERMINED TO HAVE 450.3 LBS OF FUEL AVAILABLE FOR FLT AT FORTUNA ARPT, CA, AFTER SUBTRACTING 16.0 LBS FOR TAXI AND TKOF. IT WAS DETERMINED, DURING PREFLT PLANNING, THAT IT WOULD TAKE 383.9 LBS FOR AN ALMOST DIRECT FLT TO MONTGOMERY FIELD, SAN DIEGO, CA, AT 11000 FT CRUISE ALT. THE FUEL REMAINING WAS TO BE 66.4 LBS UPON ARR AT MYF ARPT. THIS ALLOWED FOR THE 45 MIN RESERVE FOR VFR NIGHT FLT. THE WINDS ALOFT FOR THE RTE OF FLT VARIED BTWN 310 DEGS AND 030 DEGS. THE ACFT HAD A TAILWIND THE ENTIRE FLT AND THE AVERAGE GND SPD WAS 170 KTS. THE PLT REFUELED THE ACFT AT CRQ ARPT AFTER A 1 HR REST PERIOD. THE PLT THEN RAN THE ENG FOR 20 MINS TO NORMALIZE THE FUEL INJECTION SYS. THE PLT DETERMINED THE ACFT TO BE AIRWORTHY AND CONTINUED THE FLT TO MONTGOMERY FIELD, SAN DIEGO. THE PLT SUSPECTS A POSSIBLE FLOODED ENG CONDITION DEVELOPED DURING EMER PROC.
