In the course of a night training flight on 30 March 1967, and while making a simulated two-engine approach to land at New Orleans International Airport, USA, a DC-8 crashed into a residential area. The aircraft, several homes, and part of a motel was destroyed, and the six occupants of the aircraft and thirteen persons on the ground were killed.
The aircraft had taxied out for take-off only seven minutes before, at 0040 hours local time. The night was fine and clear, with no significant wind.
Under the title of A Question of Command, the following story was published in Aviation Safety Digest No. 56 dated May, 1968. It concerned a DC-8 that crashed during a night approach. A captain-trainee occupied the left hand pilot seat and a DC-8 check captain was in the right hand seat.
At 0043 hours the crew advised ATC they were ready for take-off on runway 28, and that they wished to circle and land on runway 01. At 0047 the aircraft reported on base leg for runway 01 and ATC cleared them to land.
The tower controller watched the aircraft as it turned left on to final approach. At first, the turn appeared a normal shallow turn but then the angle of bank increased and the descending turn continued until the aircraft was in a 60 degree bank on a heading of about 320 degrees. At this stage the aircraft struck power lines and crashed.
Investigation showed that the first engine failure was simulated at 0044 as the aircraft reached v1 (critical engine failure speed). One minute later, as the aircraft was climbing, a second engine failure was simulated. The aircraft was then at a height of 1,200 feet, flying at 200 knots, with Nos 1 and 2 engines at idle power.
