On July 6, 1969, a serious aircraft accident occurred on Air South Flight 168 near Monroe , Georgia . A Beechcraft 99 of the regional airline Air South fell to the ground after losing control, killing all 14 people on board.
plane
The affected machine was a Beechcraft 99. The machine had the serial number U-16 and had made its first flight in June 1968. It was then delivered to Air South, which approved the machine with the aircraft registration number N844NS . The twin-engine regional airliner was equipped with two Pratt & Whitney Canada PT6A-20 turboprop engines . By the time of the accident, the machine had completed a total of 2,226 operating hours.
Passengers and crew
The flight from Atlanta to Greenville had taken 12 passengers. There was a two-person crew on board the machine, consisting of a flight captain and a first officer. No flight attendants were provided on the regional flight.
the accident
About eleven minutes after the aircraft had reached its cruising altitude of 7,000 ft, the elevator trim began to trim the elevator up to the stop ( full nose down position). Despite the remedial measures introduced six seconds later, the strength of both pilots was insufficient to overcome the extremely trimmed position of the elevator with the control horn and to intercept the machine. As a result, the plane went into a nosedive; the resulting high speed meant that both wings exceeded their load limits and broke off a few hundred feet above the ground before the aircraft finally hit the ground almost vertically. The machine crashed at Bold Springs , ten kilometers northwest of Monroe, Georgia , killing all 14 people on board.
root cause
The NTSB was unable to determine the cause of the malfunction of the trim, but attributed the design of the entire control system to a beneficial role in causing the loss of control.
