HISTORY OF FLIGHT
On October 27, 2004 at 1050 eastern daylight time, a Beech BE-60, N611JC, registered to a private individual and operated by the airline transport pilot, collided with the ground shortly after takeoff from runway 34, at the Asheville Regional Airport, in Asheville, North Carolina. The business flight was operated under the provisions of Title 14, CFR Part 91, and instrument flight rules. Instrument meteorological conditions prevailed and an instrument flight plan was filed. The airplane sustained substantial damage. The air transport pilot, pilot rated passenger, and two other passengers received fatal injuries. The flight originated from the Asheville Regional Airport Asheville,North Carolina, on October 27, 2004 at the time of the accident.
According to witnesses, the pilot had difficulty starting the right engine. Once it started the pilot immediately taxied to runway 34 and began his takeoff roll. At about the 3,000-foot marker on the 8,000-foot long runway adjacent to taxiway 'K', witnesses saw the airplane at about 100 to 150 feet above the ground with the landing gear retracted when they heard a loud "bang". They said the airplane made no attempt to land on the remaining runway after the noise. The airplane continued climbing and seemed to gain a little altitude before passing the end of the runway. At that point the airplane began a right descending turn and was in a 60 to 80 degree right bank, nose low attitude when they lost sight of it. A few minutes later they heard the fire department responding. The airplane collided with the ground about 3/4 mile from the departure end of runway 34 in a residential area.
PERSONNEL INFORMATION
A review of information on file with the Federal Aviation Administration Airman's Certification Division, Oklahoma City, Oklahoma, revealed the pilot was issued an Airline Transport Pilot Certificate with ratings for airplane single engine land, airplane multiengine land with type ratings in the HS-125 and Lear Jet. A review of records on file with the FAA aero Medical Records revealed the pilot held a first class medical certificate issued on February 8, 2004, with a restriction that he must possess glasses for near and intermediate vision. The pilot reported on his application for the medical certificate that he had accumulated 13,400 total flight hours. The pilots personal logbook was not located for examination.
AIRCRAFT INFORMATION
Examination of the left and right engine logbooks revealed that both engine's had a factory overhaul on June 26, 1986, by Lycoming Engines, Williamsport, Pennsylvania. On February 12, 1992, the airplane was registered in the Dominica Republic and the last maintenance entry indicated that the left and right engines underwent an inspection and the total time shown on both engines was 754.3 hours since major overhaul. There were no other maintenance entries in the logbooks until the airplane was sold and moved to the United States and issued a standard airworthiness certificate by the Federal Aviation Administration on November 13, 2002, with the registration number N611JC. Examination of the left engine logbook revealed that it was a Lycoming TIO-541-E1C4, SN: RL-1752-59, rated at 380 horse power. The engine total time since overhaul was 829.3 hours as of its last annual inspection dated December 29, 2003. The logbook reflected that the engine hour meter was inoperative as of that date.
