The aircraft suffered damage when its right maingear gave way on diverted landing at Edmonton following a blown tire after take-off from Calgary.

The DHC-8-400 (Dash 8-400) suffered a right hand main gear collapsed during touchdown on runway 02 at Edmonton International Airport. It is reported that there were three injured persons.
According to media reports, the pilots elected to discontinue the flight from Calgary to Grand Prairie because of a blown tire during departure, NAV Canada is reporting

Because of a considerable crosswind factor at Calgary the pilots elected to divert to Edmonton Intl Airport.

On landing in darkness but favourable weather conditions, the right maingear gave way and the DHC-8 settled on is right wing. Major damage occured when all the propeller blades of the right engine seperated. At least one of them is known to have penetrated the fuselage impacting a passenger window in the strenghened portion of the fuselage fortunately without hitting any person inside. However, the cabin wall  was deformed by the forces of impact.

At the time it is still unclear wether the right undercarriage gave way on landing after the tire blewout.

The accident is under investigation by the TSB.

NOTE: In SEP 2007, there were 2 major landing accidents of DHC-8-400s in Vilius and Aalborg. In both cases, the right maingear collapsed on landing.
