Excellent suggestion SP, with one slight drawback as Dervish points out. Your eagle eyed Holmes spots the recurring theme in numerous BoI/SI reports of airworthiness deficiency, traces the timeline back to the late 80's/ early 90's and discovers a 28% year on year slashing of the Air Safety budget by the then RAF Chief Engineer. He hands in his finding to the DG MAA who bins it saying, "This is not new evidence". End of!
The Royal Air Force High Command lacks the moral courage to lance this boil. That is why the MAA and the MAAIB must be made independent of the MOD and of each other.
dctyke, thank you for your confirmation that I got your information right, and I am now intrigued by the issue raised between downsizer and yourself. What about the parachute? Presumably it didn't sit in the aircraft for three years, like the seat (though I dread being told that is exactly the case). So is the headbox change at the same time as an RTI crack check? If so is it therefore included in the RTI? If not is it the subject of a different Special Instruction (Technical)? Anyone?
