An Allison 606 prop blade (Electra, CV58) weighs a lot more than 10kgs...maybe 35 kgs.
I expect more than that! I understand that the whole (Hamilton Standard) prop weighs in the range of 1000 pounds. But any prop blade releasing into the fuselage side is going through.
There is a rocky ridge rising to 1500 feet directly in line with, and about 2 miles (2 runway lengths) from, the threshold of 30.
I'm not a Saab pilot, so am not qualified to comment on an acceptable approach for that type. However, I know that Dash 8-100/200 are operated out of shorter runways, with tighter approach paths than that airport. Honnigsvag, Norway, is one example, mountains within a mile of each end of the runway. For my very limited experience flying larger planes, a 20 knot tailwind into any runway would give me the willies!
