There have been three other incidents of Dash 8 landing gear collapses with SAS in 2007 and 2008 so much so that SAS grounded their entire fleet at the time. Any problems seem to have been glossed over since then.If it 'ain't broken........ Don't try to mend it !

Have there been any other accidents/incidents of this nature?
...okay - should have done some of my own reading before posting...

From what I can tell, past incidents have been related to poor maintenance and inspections. The AD following the 2008 Scandanavian incident only called for more diligent inspections. There have been problems with actuator nut corrosion, uplock wear and improperly fitted grease nipples that become dislodged and jam the downlock mechanism.
The question is: what design weaknesses may be contributing this heightened inspection and maintenance? In any case, it doesn't seem to me to be so hard to fix. Corrosion resistant hardware, more wear-resistant components, threaded grease fittings instead on press-on ones... how hard can this be?

One factor to bear in mind here, and putting aside maintenance or lack of it for now, is the number of gear cycles per day compared to larger, longer range aircraft.
The Dash 8 is essentially a commuter short range aircraft and may well have around a dozen gear cyles per day compared to a much lower number with larger long haul aircraft. A relatively new aircraft is going to wear out gear parts much quicker.
And no....I wouldn't fly in one for all the tea in China !If it 'ain't broken........ Don't try to mend it !

And what ever happened to "any landing you walk away from"?

Good landing: everybody walks away.
Perfect landing: Good landing + the airplane can be re-used without maintenance intervention.

I assume you are referring to Ryanair when you refer to "Riotair". LOL. Like it ! I'll have to use that one.
Ryanair have a very young fleet and and excellent maintenance record and I'll wager that their 737 fleet flies longer and fewer sectors per day than Dash 8 operators. Time aloft means nothing. I was referring specifically to landing gear cycles per day.If it 'ain't broken........ Don't try to mend it !

Propeller blade slices though fuselage
A woman has described how she is “lucky” to be alive after being hit in the head by a part of an aircraft’s propeller that had sliced through the plane's fuselage following an emergency landing.
If a busted landing gear then I assume the propeller blade hit the runway, broke off, then impacted the fuselage.
