I have been following this thread with great interest from the start.The very sad fact is that a great many innocent people lost their lives on this ill fated flight.Now we may argue about the missing spacer,the downwind take off,overweight,too much fuel,et al but the cause of the tyre failure and to quote another source was:
"The wear strip fell from the DC-10 onto the runway. Why? The holes on the strip were drilled close together and not in proper alignment. This particular strip was a make-shift repair strip. As the holes wore through, the mechanic drilled new holes into it. Not only were the holes too close together but they were drilled too large of a diameter. Evidence suggests that rivets pulled through the holes, causing the wear strip to fall from the DC-10."
If such a part requires replacement on an aircraft,it is replaced in accordance with the manufacturers aircraft maintenance manual/the manufacturers structural repair manual/parts selected from the manufacturers illustrated parts catalogues.Should a repair be required out of this scope i.e.materials as original equipment manufacturer or beyond normal limits,the repair must be sanctioned by the original manufacturer and followed to the letter.This guy fell down on all counts.We are talking about peoples lives here.
