The tailwind was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, takeoff - roll/run - reason for occurrence undetermined (cause) - Overrun, takeoff - aborted - weather condition - tailwind (contributing factor) - aborted takeoff - delayed, pilot in command (cause) - On ground/water encounter with terrain/water, takeoff - aborted ## Analysis Several pilot-rated ground witnesses reported that on the downwind takeoff ground run the airplane engine never developed full power and never lifted off. The pilot applied the brakes when the airplane was about 360 feet from the departure end of the runway, but he was unable to stop the airplane on the runway or the 84-ft level, gravel stopway. The airplane overran the departure end of the runway and went down the 40-degree sloping terrain and exploded. The entire airplane was incinerated. The engine examination showed that the No. 1 cylinder boss was cracked and the interior of its valve cover contained two impact marks. Examination of the cylinder and its components showed no evidence of any preexisting malfunctions or failures. ## Factual narrative History of Flight On September 3, 1995, at 0943 hours Pacific daylight time, an experimental R.A. Floyd Lancair 200 SE, N92RF, exited the departure end of runway 34, went down an embankment, and exploded at Georgetown Airport, Georgetown, California. The pilot was beginning a visual flight rules personal flight to Corona Airport, Corona, California. The airplane, registered to and operated by the pilot, was destroyed by impact and the postimpact fire; several trees were also destroyed. The certificated private pilot and his wife sustained fatal injuries. Visual meteorological conditions prevailed. National Transportation Safety Board investigators interviewed the owner of Skyways Flying Service, a fixed-base operator at the airport. The owner said the pilot arrived at Georgetown Airport on September 1, 1995, in the late afternoon to attend a scheduled Experimental Aircraft Association fly-in. On September 3, 1995, the pilot personally fueled his airplane with 7 gallons of 100 octane, low lead gas, in each main wing fuel tank. He did not know if this fuel topped-off all of the fuel tanks. The owner, a certificated commercial pilot and aircraft mechanic, said that he was in front of his facility when the airplane departed runway 34. He said that the prevailing winds were from the south between 3 and 5 knots; the winds favored runway 16. During the takeoff ground run, the airplane was not accelerating properly and that the engine was not developing full power. The engine was not sputtering or backfiring, but was producing a power sound equivalent to a "fast taxi." When the airplane passed his facility, about 1/3 of the runway length, it was not accelerating properly. He said that he knew something was going to happen and went for his truck. When he got to his truck, the airplane exited the runway and plunged over the embankment and crashed. He observed a fireball while driving toward the accident site. The airplane never lifted off while he observed it, nor did the engine power sound decrease. Other pilot ground witnesses repeated the owner's statement. All of the witnesses said the engine was not developing full power, but that the engine was not missing, backfiring, or sputtering. One witness said that when the airplane was at midfield, its speed was between 40 and 50 miles per hour. Four of the witnesses reported that they observed smoke emanating from the wheel brakes when the airplane passed runway 16 go-around line (about 150 yards from the departure end of runway 34). The airplane exited the runway and plunged down the embankment. The accident coordinates are: 38 degrees, 55.55 minutes north latitude and 120 degrees, 51.87 minutes west longitude. Crew Information The pilot held a private pilot certificate with an airplane single-engine land rating and a third-class medical certificate dated June 6, 1995; the certificate contained a "must wear glasses for near and distant vision" restriction. He also held an aircraft repairman (experimental) certificate with the following limitations: Inspection certificate for experimental aircraft make Floyd Model Lancair Serial No. 107. Certification date August 11, 1989. The pilot's flight hours logbook was not recovered. The flight hours reflected on page 3 of this report were obtained from the pilot's last medical application form. Safety Board investigators were unable to determine if the pilot satisfied the pertinent federal air regulations general and recency requirements, including the required biennial flight review. The pilot's hangar partner told Safety Board investigators that he had flown the airplane about 25 hours since the engine was reinstalled in the airplane. Airplane Information The FAA records show that the pilot built the accident airplane. The FAA issued the airplane its airworthiness certificate on June 15, 1991. The pilot's hangar partner told Safety Board investigators that sometime in 1994 the pilot received contaminated fuel. The fuel company agreed to pay the pilot to have the engine overhauled. The pilot removed the engine and sent it to DeMars Engine Rebuilders, Colorado Springs, Colorado. DeMars Engine Rebuilders records show that the engine was rebuilt to zero time standards and returned to the owner on September 14, 1994; the engine accrued 1,567.3 hours. During the overhaul, the engine crankshaft was replaced with a Continental PC-60 (Packette) engine crankshaft in accordance with an FAA sealed copy of Ken Hatfield Enterprises Engineering Authorization No.84-5, Revision B, dated December 10, 1985. In addition, the dome shaped pistons were installed. The pistons were obtained from Light Speed Engineering, Santa Paula, California, and the cylinders were obtained from A.E.R.O. Aviation Company, Inc., Granite City, Illinois. Airport Information The airport is in Class G airspace and does not have any FAA air traffic facilities. It has a single asphalt surfaced runway that is 2,980 feet long by 60 feet wide. The runway is oriented in a northwest/southeast (34/16) direction. Trees surround the airport from the east to the west. The terrain slopes downward about 40 degrees at the departure end of runway 34. The area between the departure end of runway 34 and the beginning of the downward sloping terrain is a hard gravel surface that extends about 87 feet. Meteorological Information The airport does not have an official weather observation facility. The weather data reflected on page 4 was obtained from ground witnesses. One ground witness told Safety Board investigators that he has an air data computer in his airplane. This computer measures the ambient temperature and the airplane's pressure altitude. After the accident, the witness turned on the air data computer and determined that the prevailing density altitude was 5,090 feet. McClellan Air Force Base, Sacramento, California, is the nearest official weather observation facility, located about 35 miles southwest of the accident site. The 0855 hours surface weather observation was: Scattered clouds - 10,000 feet; visibility - 30 miles; temperature - 64 degrees' F; dew point 53 degrees' F; surface winds - 150 degrees at 10 knots Wreckage and Impact Information Ground scars and the wreckage examination revealed tire skid marks east of the runway centerline beginning about 360 feet from the departure end of the runway. The tire marks continued on the gravel overrun area until the airplane went over the cliff embankment. The initial ground impact point is about 189 feet northwest of the departure end of the runway and its elevation is 2,569 feet msl. The main wreckage came to rest, inverted, about 231 feet northwest of the departure end of runway 34 and its elevation is 2,540 feet msl. About an acre of forest vegetation was burned during the postimpact fire. The entire airplane was incinerated. Safety Board investigators were unable to identify any flight control surfaces. Only the wing tips were identifiable. All of the instruments were destroyed by fire. The throttle and mixture controls were found in the full open and full rich positions, respectively. The propeller blades separated from the hub assembly. Remnants of the propeller blade were found at the initial impact point. The wooden propeller blades displayed chordwise scuffing, but no leading edge gouging, and were shattered. The engine compartment forward of the firewall separated from the airframe and was found inverted at the main wreckage area. The engine sustained extreme postimpact fire damage. The engine was disassembled and examined at Plain Parts, Pleasant Grove, California, on September 4, 1995. As previously stated, the engine sustained extensive postimpact fire damage, but minimal ground impact damage. Investigators were unable to rotate the ## Aircraft - Registration: [N92RF](https://openairdocs.org/deregistered/N92RF-1996-01-11), registration cancelled 1996-01-11, S/N 107 (OpenAirDocs) - Reported make and model: FLOYD LANCAIR 200 SE (LANCAIR 20) - Registry model: [Robert A Floyd LANCAIR 200 SE](https://openairdocs.org/model/robert-a-floyd-lancair-200-se) (registry code 05612A2) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 107 - Engines: Rolls-Royce O-200-A 100 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Registered owner: Robert A.
