Had a similar landing incident at Plymouth Airport EGHD with Dash-8-300 GBRYP a few years back - a/c hit winshear on short finals and slammed onto the deck causing the left main gear to collapse.
Looks like the fuse pin saved the day again and avoided the landing gear puncturing the fuel tank and should also cause a slow collapse of the gear, hence the position of the aircraft.
Have tried to find the pics on the internet but no luck.....there are some around. At least with the Wideroe a/c the landing gear did what it was designed to do.
ps the Wideroe a/c isn't a -300
