SW4, Thompson MB Canada, 2017

Summary

On 2 November 2017, a Fairchild SA 227-AC Metro III landing at Thompson after a ferry-permit flight issued to facilitate a hydraulic fluid leak rectification left the runway when reverse pitch was selected and sustained substantial damage. The Investigation found that the flight had been continued without shutting down the left engine when its oil pressure dropped below the level requiring this in the QRH. The oil loss was found to be attributable to the same cause as a similar loss identified two days previously for which rectification had supposedly been achieved. The hydraulic leak did not affect the flight.
