Accident Overview
A Viscount aircraft was performing a semi-annual flight crew check involving a simulated two-engines-out emergency landing. The aircraft was approaching Ciampino's runway 16R with engines number 3 and 4 inoperative. Approximately 400 meters short of the runway threshold, the aircraft suddenly entered a right bank. It struck the ground with the right wingtip, crashed, and caught fire. Both pilots on board were killed.
Context of the Flight
The flight was part of a routine crew proficiency evaluation. The exercise simulated a scenario in which two of the aircraft's four engines were shut down. At the time of the accident, engines 3 and 4 were out, while engines 1 and 2 were operating.
Official Findings
The probable cause, as determined by the investigation, was a balked landing manoeuvre executed below the speed limits required for safe directional control during a critical situation. This situation developed in the final phase of the landing while conducting the simulated emergency exercise with two power units inoperative (number 3 and 4) and two operative (number 1 and 2).
