Sad but True
Sumps, I fully understand your concerns. I have met and worked with many engineers in my current job over the last 9 years and it still amazes me when I quote some aspect of JSP 553 and they look at me with that blank, eyes glazed expression (although that might just be their natural reaction to me!) meaning they have no idea what I'm wittering on about.
It may just be the mists of time and too many happy hours but I seem to have a vague recollection that we were first introduced to Airworthiness concepts as baby pilots on Jet Provosts. OK, so everyone was bored stiff, just not exciting bedtime reading is it? My next CPA with Airworthiness was when I went to CFS 10 years later and I paid a bit more attention that time. It was only an hour or so but it covered all the basics of fatigue, stress, design, testing, RTS etc.
Maybe Cosford, along with the other relevant training 'centres of excellence' should introduce mandatory Airworthiness awareness packages?
