Casualties: Fatalities: 6 / Occupants: 6
Component Affected: Aircraft CG position calculationAircraft CG position calculation
Category: Accident

A training flight of 3 hours and 14 minutes resulted in an overshoot on Cairo runway 23. The aircraft, Nefertiti, crashed while climbing out due to a persistent, increasing pitching-up attitude during the overshoot, leading to stalling at an insufficient altitude for recovery. Inaccurate CG position calculation prior to takeoff and potential ballast movement aft during flight contributed to this outcome.A training flight of 3 hours and 14 minutes resulted in an overshoot on Cairo runway 23.

Description
After a training flight of 3h14 min an overshoot was practiced on Cairo runway 23. The aircraft, named “Nefertiti”, lost control and crashed while climbing out. PROBABLE CAUSE: Continual increase of pitching up attitude during overshoot which lead to the stalling of the aircraft at an insufficient height for recovery. Contributing were the inaccurate calculation of the CG position before takeoff and the possibility of movement of the ballast weight aft during flight.
