A Rexall Drug and Chemical Company Lear Jet, N235R, crashed approximately 1.5 miles southwest of Clarendon, Texas, at about 1238 on April 23, 1966. Both of the crewmembers were fatally injured. There were no passengers. The aircraft was destroyed. The flight, for the purpose of issuing a type rating to the pilot, was returning to Fort Worth from Amarillo, Texas. During an unrestricted climb to Flight Level 410, there were numerous routine communications between various air traffic control facilities and the flight. The last intelligible transmission was an acknowledgement of instructions to change radio frequencies, at approximately 1234. About 54 seconds later an open microphone carrier tone, lasting 15.5 seconds, was received from the aircraft. At 1235:40 the radar target from the aircraft disappeared. The weather existing at the time of the accident included cirrus clouds and moderate to severe turbulence associated with a jet stream with wind velocities in excess of 75 knots. The Board determines that the probable cause of this accident was the loss of control of the aircraft, in turbulent, instrument conditions, which could have been caused by a failure of both gyro horizons.
