The Dhahran airbridge was operated by 1 F27 from PLAD based in BAH ..... It was maximum punishment flying, very short flights at low altitude in humid air laden with dust. I've seen Dart compressor blades reduced to 25% when removed on scheduled overhaul.
When I trained on them, back in 1966 or so, the Dart had NO "compressor" blades. Did something change? Why wasn't I told
