The bit I did like from Dekker's report was his hindsight diagram. Most posters here are commenting with hindsight. To avoid getting into the pre event situation, follow procedures.
Of course any event can crop up at any time and catch people out. The point I am making is that there is a definite trend creeping up on us and that is complacency and non adherence to procedures.
The whole point of procedures is to reduce risk. We cannot cover every possibility but following procedures should cover most.
XL test flight not in accordance with recommendations
(no accident if test flight procedures followed)
easyjet near accident, not entering problems in the tech log
(no incident if problem entered in tech log)
spanair repeated fault not dealt with properly
(no accident if repeat item repaired even if flap setting forgotten)
turkish repeat fault not dealt with properly
(no accident if enterd in tech log and follow MEL procedure, pull cb ra 1 inop no influence on A/T)
korean 747 stansted ADI fault not dealt with properly captain crashed aircraft following defective adi
(no accident if repair before flight or set inop if MEL allows)
So yes, you could try and find excuses/explanations for all these happenings or you could just emphasize that procedures must be followed to the letter.
Or you could properly investigate why so many are overlooking procedures. The common thread linking all these accidents is not flying skills as such, it is human behaviour.
