Temco GC-1B Swift, N3825K: Accident occurred October 02, 2011 in Ewell, Maryland

NTSB Identification: ERA12FA002 
 14 CFR Part 91: General Aviation
Accident occurred Sunday, October 02, 2011 in Ewell, MD
Probable Cause Approval Date: 09/13/2012
Aircraft: TEMCO GC-1B, registration: N3825K
Injuries: 1 Fatal,1 Serious.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.


The pilot made an uneventful 45-minute cross country flight from his home airport to the destination airport. About 10 minutes into the return flight, the airplane was cruising over water at 2,000 feet mean sea level when it experienced a total loss of engine power. The pilot attempted to glide to an island and performed emergency procedures; however, he did not verify the position of the fuel tank selector. The airplane glided about 2 miles before ditching in the water. The airplane was equipped with main and auxiliary fuel tanks that held 26 and 9 gallons of fuel, respectively, and the engine burned about 9 gallons of fuel per hour; the pilot reported that both tanks were full when he departed from his home airport. The pilot further reported that, if he had accidentally left the fuel selector positioned to the auxiliary fuel tank prior to departing his home airport, he would have had just enough fuel to fly the outbound leg, begin the return leg, and lose engine power where he did. When the airplane was recovered, the fuel selector was found positioned to the auxiliary fuel tank. Examination of the wreckage did not reveal any preimpact mechanical malfunctions. In the pilot’s operating handbook for the airplane, the procedure for an engine failure during flight stated that, for airplanes equipped with an auxiliary fuel tank, the pilot should ascertain that the fuel selector valve is on a tank containing fuel.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's improper fuel management in that he did not verify the fuel selector position before beginning the flight or after the power loss, which resulted in a total loss of engine power due to fuel starvation and subsequent ditching.

HISTORY OF FLIGHT


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.

PILOT INFORMATION

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.

AIRCRAFT INFORMATION

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.

METEOROLOGICAL INFORMATION

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.

WRECKAGE INFORMATION

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.

MEDICAL AND PATHOLOGICAL INFORMATION

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."

ADDITIONAL INFORMATION

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:

"Engine Failure During Flight

If airplane is equipped with auxiliary fuel tank, ascertain that fuel selector valve is on tank containing most fuel…"

 HAGERSTOWN, Md. —  A pilot watched his injured, 78-year-old mother die in the rough waters of the Chesapeake Bay as they both tried to swim to safety after his single-engine airplane crashed and sank more than a mile off the shore of Smith Island, Maryland State Police said Monday.

Lanson C Ross III, 48, of Fort Washington, was treated for minor injuries after reaching the island at about 8 p.m. Sunday, more than four hours after his Globe GC-1 Swift plane disappeared from radar. Police said the plane was about three miles southwest of the island when it disappeared.

His mother was Mary L. Lagerquist, of Sequim, Wash.

Ross told police that he had flown his mother in the two-seater on Sunday from Hyde Field in Clinton to Tangier Island in the Chesapeake Bay. They were starting their trip back to Clinton when the plane malfunctioned, he said. Police say Ross radioed the nearby Patuxent River Naval Air Station and told them he would try to reach Smith Island.

He told police he was forced to land in the water and the plane sank rapidly after he and his mother got out. Ross said his mother was hurt but managed to swim about a mile with his help.

"Ross said after about a mile of swimming in rough water with waves three to five feet high, his mother passed away Ross continued on and was able to reach the island," Maryland State Police spokesman Greg Shipley said in a written statement.

The plane hasn't been found, Shipley said.

The National Transportation Safety Board said it has assigned an investigator to the case.
