From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On April 17, 1999, about 1451 eastern daylight time, a Learjet 24B, N70TJ, registered to and oerated by yelvington transport, inc., as a title 14 CFR part 91 corporate flight, had a wing flap hinge fitting separate, which resulted in the wing flap binding adjacent aileron, shortly after takeoff from fort Lauderdale executive airport, fort Lauderdale, Florida. Visual meteorological conditions prevailed at the time and an instrument flight rules flight plan was filed. The aircraft received minor damage and the airline transport-rated pilot and commercial-rated copilot were not injured. The flight was originating at the time of the incident. The pilot stated he was in the right seat and the copilot was flying the aircraft from the left seat. Shortly after takeoff from runway 26 at the fort Lauderdale executive airport, they retracted the landing gear and then the wing flaps, at which time he heard the landing gear warning horn. He then noticed the aircraft was in a steep right bank and the copilot was having trouble with the controls. He took control of the aircraft and found that by holding extreme forces on the control wheel in attempt to roll the aircraft back to the left, and found that by holding extreme forces on the control wheel in attempt to roll the aircraft back to the left, the aircraft continued to roll to the right. He reduced left engine power and increased right engine power, which resulted in a decreased right bank angle. They reported the flight control malfunction to the FAA fort Lauderdale executive airport control tower controller, and continued the right turn around for a landing back on runway 26. Postlanding examination of the aircraft by NTSB showed the right wing flap inboard hinge fitting had separated from the wing flap. The wing flap had shifted outboard and the outboard edge of the flap had contacted the inboard edge of the right aileron, forcing it upward and binding it in that position. (-23) conversations with ATC and maintenance personnel from noble jet, inc., revealed the co-pilot was flying the aircraft from the left seat when shortly after take off, yelvington was experiencing difficulty with the controls with the a/c in a steep right bank - the pilot (from the right) seat took control of the aircraft. ATC stated they reported a flight control malfunction & requested clearance to land. Isis indicates gary c. ye lvington did not have a current medical certificate i/a/w 61.3(c). (See attached) NTSB preliminary report dated 04/19/99.
