The AAIB said: “The serious incident was caused by the commander trying to make a gentle landing and misreading the perspective of the runway due to the runway slope and not realising that the aircraft was going so long.
“Due to the lack of experience of the other pilots on board, they did not inform the commander of the need to go around.
“Under the circumstances, having overshot the touchdown zone on a relatively short runway a go-around would have been expected.”
The AAIB added: “Having touched down, the runway remaining was considerably shorter than planned but, judging he had sufficient runway ahead, the commander delayed applying full braking and did not make use of reverse propeller pitch to slow the aircraft.
“This proved inadequate to stop the aircraft in the remaining distance, although the aircraft left the runway at relatively low speed.”
