On 26 May 2013, a Porter Airlines DHC8-400 sustained substantial damage as a result of a mishandled night landing off a visual approach at Sault Ste. Marie which led to a 3g tail strike. The prior approach was stabilised at 500 feet but then unstabilised below that height. The handling pilot involved was a First Officer with 134 hours experience on the aircraft type, which was his first experience of multi crew transport aircraft after significant experience flying light aircraft. An absence of effective monitoring or intervention by the aircraft commander was identified during the Investigation.
