NTSB summary
HISTORY OF FLIGHT On September 27, 1993, at 1123 eastern daylight time (EDT), an Aero Commander 690A, N242TC, operated by Midwest Flying Service, Incorporated, of Runyard, Michigan, and piloted by commercially certificated pilots, was destroyed when it collided with trees and terrain following witness reported maneuvering. Instrument meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 positioning flight was operating on an IFR flight plan. Both pilots were fatally injured. The flight departed Lansing, Michigan, at 1117 EDT. The air traffic controller handling N242TC's flight told the pilot to turn to a 230 degree heading and climb to 4,000 feet mean sea level (msl). Shortly after receiving the heading and altitude clearance, the departure controller called the pilot twice before being acknowledged. After acknowledging the controller, the pilot was called two additional times before he advised the controller that "...we got a problem here." The tower cab supervisor observed N242TC's target on the radar scope after takeoff. He stated: The aircraft's altitude varied rapidly for the next several sweeps of the radar. I observed the aircraft's altitude readout jump from 3,000 feet one sweep to 2,200 feet the next sweep." He said he observed the aircraft descend to 1,700 feet msl on the third radar scope sweep. While the altitude changes were occurring, the supervisor observed N242TC change its heading from south to southeast to east. A second air traffic controller said that N242TC was "...continually changing direction, and his altitude was changi
Probable cause
was the pilot-in-command not maintaining aircraft control during the intermittent operation of the electrically operated attitude gyro. Factor's associated with this accident are an fluctuating (intermittent) electrical system inverter and the pilot-in-command not performing remedial action by using the vacuum powered attitude gyro and other flight instruments once the airplane was making a series
