What happened
During a semi-annual flight crew proficiency check, a Vickers Viscount was performing a maneuver simulating an emergency landing with two engines inoperative. The aircraft was operating with engines number 3 and 4 shut down, relying solely on the remaining two power units.
As the aircraft approached runway 16R at Ciampino, it entered a sudden right bank approximately 400 meters before reaching the runway threshold. This maneuver led to the aircraft striking the ground with its right wingtip, which subsequently resulted in a crash and an intense fire. The accident resulted in two fatalities, as both pilots on board were killed.
Findings
Investigations into the crash determined that the accident occurred during a balked landing attempt. The primary factor was that the maneuver was executed at a speed insufficient to maintain safe directional control of the aircraft. This loss of control developed during the final phase of the landing while the crew was managing the simulated emergency conditions involving the two inactive engines.
