 Although no major problems were encountered during the initial testing phase , some minor issues with the landing gear and flight control system had to be rectified . The former problem was partly due to the tandem main landing gear being very narrow , in order to fit into the wings ; the leg shortened in length and rotated as it was stowed . During one landing incident , the chain mechanism ( used to shorten the gear ) in the Mark 1 gear jammed , resulting in incomplete rotation . In a second incident with Arrow 202 on 11 November 1958 , the flight control system commanded elevons full down at landing ; the resulting reduction in weight on the gears reduced the effective tire friction , ultimately resulting in brake lockup and subsequent gear collapse . A photograph taken of the incident proved that inadvertent flight control activation had caused the accident . The only occasion when a test flight was diverted occurred on 2 February 1959 , when a TCA Viscount crash @-@ landed in Toronto , necessitating a landing at CFB Trenton .
