N3825KTemco GC-1B · 1948

On October 2, 2011, at 1513 eastern daylight time, a Temco GC-1B (Swift), N3825K, operated by a private individual, was substantially damaged during a ditching in the Chesapeake Bay, near Ewell, Maryland. The certificated airline transport pilot received serious injuries and the passenger was fatally injured. The personal flight was conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the planned flight to Washington Executive Airport (W32), Clinton, Maryland. The flight originated from Tangier Island Airport (TGI), Tangier, Virginia, about 1500.

During a subsequent telephone interview with a Federal Aviation Administration (FAA) inspector, the pilot stated that prior that day, he flew uneventfully from W32 to TGI. During the return flight, the airplane was cruising at 2,000 feet mean seal level to remain below an overcast cloud layer at 2,200 feet. About 10 minutes after departure, while flying over water, the airplane experienced a total loss of engine power. At that time, the pilot was in radio contact with air traffic control, and advised of his emergency. The controller acknowledged the transmission and provided a vector to the nearest land, which was Smith Island, Maryland, about 6 miles east of the airplane. While gliding toward the island, the pilot performed emergency procedures, which included activating the carburetor heat, checking the magnetos, activating the fuel boost pump, and positioning the mixture to rich. The pilot did not mention switching the fuel tank selector position as part of the procedure. He remarked that if he had accidentally left the fuel selector positioned to "Aux," prior to departing W32, he would have had just enough fuel to fly from W32, to TGI, and lose engine power near Smith Island.

The pilot added that his airplane did not have a good glide ratio, and estimated that he only glided about 2 miles before ditching in the water. Other airplanes and helicopters circled the area about 20 to 30 minutes after ditching; however, the pilot and passenger were wearing dark clothes and were not seen. The pilot and passenger then attempted to swim to Smith Island. The waves were high and the passenger was unable to complete the swim.

The wreckage was located on October 6, 2011, by the Maryland Department of Natural Resources. It was resting in 25 feet of water, about 2 miles west of Smith Island.

The pilot, age 48, held an airline transport pilot certificate, with a rating for airplane multiengine land. He also held a commercial pilot certificate, with a rating for airplane single-engine land. His most recent FAA second-class medical certificate was issued on December 3, 2009. The pilot reported a total flight experience of 6,800 hours; of which, 130 hours were in single-engine airplanes. Of the 130 hours, 120 hours were in the same make and model as the accident airplane. The pilot had flown the make and model accident airplane 8 hours during the 30-day period preceding the accident.

The two-seat, low-wing, retractable-gear tailwheel airplane, serial number 3514, was manufactured in 1948. It was powered by a Continental O-300, 145-horsepower engine, equipped with a fixed-pitch wooden propeller. The airplane's most recent annual inspection was performed on March 25, 2011. At that time, the airframe had accumulated 4,470 total hours of operation and the engine had accumulated 85 hours since overhaul. The airplane flew 35 hours from the time of the last annual inspection, until the accident.

The airplane's fuel selector had three positions; "AUX," "MAIN," and "OFF." The auxiliary fuel tank held 9 gallons of fuel and the main fuel tank held 26 gallons of fuel.

Patuxent River Naval Air Station (NHK), Patuxent River, Maryland, was located about 15 miles northwest of the accident site. The recorded weather at NHK, at 1452, was: wind from 250 degrees at 9 knots; visibility 10 miles in light rain; few clouds at 2,000 feet, broken ceiling at 3,600 feet, overcast ceiling at 4,400 feet; temperature 11 degrees C; dew point 8 degrees C; altimeter 29.88 inches of mercury.

The wreckage was recovered from Chesapeake Bay on November 26, 2011 and examined at a recovery facility. Underwater video recorded just prior to recovery revealed that the fuel selector was found in the "AUX" position. Additionally, the fuel selector was noted in the "AUX" position at the recovery facility. The engine had separated during recovery. The empennage had also separated and was not recovered. Both wings were intact and remained attached to the fuselage. The fuel tanks were breached and contained saltwater. The right aileron was up and the left aileron was down. The left and right flaps were partially extended. Control continuity was confirmed from the yoke to the ailerons. Rudder control continuity was confirmed from the pedals in the cockpit to the cable cuts at the point the empennage was separated. Elevator control continuity could not be confirmed due to lower fuselage impact damage.

Examination of the engine revealed that the left magneto had separated and the right magneto remained attached. One wooden propeller blade had separated about 1-foot outboard of the propeller hub and the other wooden propeller blade remained attached. The valve covers and sparkplugs were removed for examination. The sparkplug electrodes were intact with no preimpact debris noted. When the propeller was rotated by hand, camshaft, crankshaft, and valvetrain continuity were confirmed. Additionally, thumb compression was attained on all cylinders.

An autopsy was performed on the passenger on October 4, 2011, by the Virginia Department of Health, Office of The Chief Medical Examiner, Norfolk, Virginia. The cause of death was noted as, "drowning; contributing, multiple blunt trauma."

Review of the make and model engine operator's manual revealed that the average fuel burn for the engine was 9.27 gallons-per-hour during cruise flight.

Review of a pilot operating handbook for the make and model airplane revealed:
