On March 28, 2009, about 1330 Pacific daylight time, a Cessna T210L, N2445S, impacted the terrain during a forced landing about one mile north of Madera Municipal Airport, Madera, California. The private pilot and his passenger received serious injuries, and the airplane, which was owned by the passenger, sustained substantial damage. The 14 Code of Federal Regulations Part 91 personal pleasure flight, which departed Harris Ranch Airport, Coalinga, CA, about 40 minutes prior to the accident, was being operated in visual meteorological conditions. No flight plan had been filed. According to the pilot, when he entered the traffic pattern at Madera, where he planned to make a full-stop landing, he asked his passenger if he would also like to make one landing for currency. Since the passenger replied that he would like to make a landing, the pilot changed his planned full-stop landing to a touch-and-go. During the initial climb after the touch-and-go, the airplane's engine began to sputter, and about five seconds later it lost all power while it was about 500 feet above ground level (AGL). The pilot checked to make sure the magneto switch was in the BOTH position, but because of the low altitude and the descent of the airplane, he did not make a restart attempt. Instead he decided to focus on making a power-off forced landing. He therefore turned toward a nearby open area, left the gear fully retracted, and concentrated on making a successful touchdown. After the touchdown, the airplane slid across a road and entered a grape orchard where the vegetation was supported by closely spaced posts. When a Federal Aviation Administration (FAA) Inspector responded to the scene about two hours after the accident, he found no fuel in either of the airplanes wings. He then confirmed that the fuel caps were on tight, and checked for any evidence of in-flight or on-ground fuel leakage, of which there was none. During the investigation, it was revealed that when the local fire department used a hydraulic cutting device to remove the injured occupants, they severed the fuel line that runs down the right forward door post. Because the airplane came to rest with the right wing higher than the left, this action would have allowed any remaining usable fuel from the right wing to drain out after it was cut. Therefore, the NTSB Investigator-In-Charge (IIC) contacted the on-scene commander from the Madera Fire department to determine if fuel had drained from that line. According to that individual, who confirmed that he had seen the door post being cut, and also observed the occupants being removed, no fuel drained from the line. An FAA-monitored post-accident inspection of the engine and the airframe did not reveal any evidence of malfunctions or anomalies that would have precluded the engine from producing rated horsepower, or would have allowed fuel to leak from the airplane. According to the pilot, earlier in the day, prior to the flight from Madera to Harris Ranch, he used a fuel tank dipping tube to measure the level of both fuel tanks. At that time he estimated each tank was about one-half full (about 22 gallons each), which would have provided a little over two hours flying time based upon his flight planning fuel flows. He then flew to Harris Ranch and back, for a total block-to-block time that he said could have been as much as one hour and twenty minutes. When questioned further by the IIC about his fuel measurement and fuel monitoring process, the pilot stated that the wing tank fuel dip tube was not one of the types that had been designed and marked specifically for use on the Cessna 210. He also confirmed that neither he nor the owner had put the tube through a calibrating process that would ensure its accuracy with this specific airplane. He also confirmed that although he had dipped the tanks prior to leaving Madera, he had not done so prior to the return flight from Harris Ranch. Upon further questioning, he also stated that he did not remember checking the fuel quantity in the left tank when he switched to it upon entering the pattern, nor did he check the left tank fuel level prior to asking the passenger if he would like to make a landing. When asked why he selected the left tank for landing, he said that it was standard procedure with this airplane because the owner had at some time in the past experienced a momentary interruption in fuel flow from the right tank while at altitude. Because of that event, both this pilot and the owner always switched to the left tank upon entering the pattern, regardless of which tank had the higher fuel level.
