Waxahachie, TX, USA
N5553C
Cessna T210
The pilot was departing on a cross-country flight; witnesses reported that the engine did not sound like it was producing full power. The pilot stated that he did not feel it was safe to land straight ahead due to the terrain. While the airplane was still at a low altitude, the pilot made a slight right turn and then a steep left downwind turn, and the airplane descended nose-down into terrain. The airplane cartwheeled, resulting in the engine separating from the fuselage and substantial damage to the left wing. Postaccident examination of the airplane found water and contaminants in the fuel divider and multiple fuel injector lines and multiple cups of water and contaminants were sumped from the header fuel tanks. A mechanic who was familiar with the airplane reported that before the accident flight, the pilot sumped a large amount of water from the fuel tanks but did not follow the mechanic’s recommendation to taxi the airplane around or to conduct an extended preflight run-up of the engine before takeoff. The airplane had been primarily stored outdoors and had only been operated 0.2 hour in the last 8 months. No other mechanical anomalies were noted with the airframe or engine that would have precluded normal operations. Witnesses stated there was runway ahead on the 6,500 ft runway and a clearway beyond the runway for a straight-ahead emergency landing, but the pilot said he was concerned with the creek and trees in front of him. It is likely that during the pilot’s preflight preparations, he did not detect and remove the large amounts of water and contaminants in the fuel system, which prevented the engine from operating normally and resulted in a partial loss of engine power. Further, the pilot’s decision to attempt to return to the airport by conducting a steep turn resulted in an aerodynamic stall and impact with terrain.
On March 25, 2020, about 1655 CDT, a Cessna T210 N airplane, N5553C, was substantially damaged when it was involved in an accident near Waxahachie, Texas. The private pilot sustained serious injury. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 flight. A family member told investigators the pilot was going to fly the airplane to Live Oak County Airport (8T6), George West, Texas. Witnesses observed the airplane takeoff from Mid-Way Regional Airport (JWY) on runway 18 and reported the engine did not sound like it was making takeoff power. The airplane reached 50-100 ft above ground level (AGL), started a right turn, and then made a hard left downwind turn. The airplane then descended in a nose down attitude and impacted terrain. The airplane cartwheeled two times before it come to rest upright. The left wing was fractured mid-span and the engine was separated from the fuselage. The pilot said he did not think he could safely land off the departure end of the runway when the engine lost power because of a creek and trees in the area. Witnesses said the pilot could have landed on the runway or the ½ mile of open space past the end of the runway, and there was a strong tailwind when the pilot turned downwind. One witness reported the airplane had flown very little in the three years before the accident and it had been stored outside at JWY during that time. The mechanic who performed the last two annual inspections on the airplane, was also a witness to the accident. The mechanic stated during the 2019 annual inspection he completely drained the fuel tanks and ran the engine for about 45 minutes without any problems noted. He anticipated the pilot was going to pick up the airplane following the inspection, but the pilot did not for an unknown reason. When the pilot arrived the day of the accident the mechanic helped the pilot sump several cups of water from the fuel tanks before the airplane was refueled. He advised the pilot to sump all the tanks again and to taxi the airplane for a while and do a good run-up before flying it. He said the pilot told him he did not have time for that and needed to get going. The pilot had the airplane fueled prior to departing. The lineman who refueled the airplane stated the pilot was sumping the fuel tanks while he was present, and the pilot told him to fuel the left tank first because "he was getting a lot of stuff" out of the right tank. The lineman noted he did not observe any rust or debris around the left fuel cap. He did note rust around the right fuel tank filler, rust on the right fuel cap, and rust stains on the fuel cap gasket. He topped off both the left and right tanks (total capacity 90 gallons) with 41.2 gallons of fuel. The pilot said it had rained a couple days prior to the accident and he drained a lot of water from the fuel tanks prior to the flight. He said he let the airplane sit for a while and came back and sumped the tanks again until only fuel came out. He said he planned to fly around the pattern a few times to make sure everything was working correctly. Following the accident, a Federal Aviation Administration inspector drained two sump cups full of contaminants and water from the left header fuel tank and 12 sump samples of water from the right header fuel before fuel was sumped from the tank. An examination was conducted on the engine. Liquid consistent with AVGAS was found in the fuel injector lines to the cylinders 2, 3, and 6. The injector lines to cylinders 1, 4, and 5 contained water. The inlet line to the fuel divider was removed and water and "a thick grey paste" came out of the fuel inlet. Upon disassembly of the fuel flow divider the diaphragm and spring were intact. A fine sand-like material was located on top of the diaphragm. The steel ring in the center of the fuel screen was completely covered in rust. The inlet side of the fuel screen also contained the sand-like material. Upon removal of the diaphragm and spring there was a large amount of foreign material in the fuel divider. There was no odor or indication of AVGAS in the fuel divider. No other anomalies that would have contributed to a loss of engine power were identified during the examination. A review of the airplane maintenance logbooks showed the last three annual inspections were conducted on September 27, 2016, at 4,973.4 hours total time, December 18, 2017, at 4,981.2 hours total time, and September 19, 2019, at 4,981.7 hours total time. The airplane tachometer read 4,981.9 hours at the time of the accident. The pilot said that after he had the annual inspection completed in September, 2019, he decided to leave the airplane at JWY and have it repainted.
The partial loss of engine power due to water and contaminants in the fuel, due to the pilot’s inadequate preflight inspection, and the pilot’s decision to conduct a steep turn at low altitude to return to the runway rather than land straight ahead, which resulted in an aerodynamic stall.
