Hi Guys, having to work within the aircraft specifications as mentioned is disconcerting to say the least, especially when referred to other sections in the manufactures Standard Practices Manual that mentions peening IAW AMS 2430! The manufactures in the airline industry seem to have been left behind at the level shot peening was 5 or 6 years ago. We have been pushing for them to update their specifications for a couple of years now. There is some talk from one of our OEMís for change to align with AMS2430. Lets hope it gains momentum!
