Why would a company say that a procedure "didn't matter"?
Does anyone remember the issue with servicing the jet engines on the DC 10s?
The proper way was to disconnect the engine from the huge bracket that connected it to the wing. That took about 200 man hours. Some genius found that you could remove a few huge bolts and drop the engine ( a few hours of work) - unfortunately - reinstalling it that way easily cracked the attachment bracket over time.
One DC 10 crashed at Chicago after its engine fell off on take-off. Plane crashed with the worst death toll in U.S. aviation history.
All DC10s grounded - none even allowed to fly into U.S. airspace.
Checks of all mounting brackets on every DC 10 done - dozens of more DC 10 brackets in imminent danger of failure.
Seems ALL of the airlines had shared the short-cut to save time/money!
The genius who thought-up the short cut caused many millions of dollars of damage and just under 300 deaths.
As my grandfather used to say you can do it fast or right - pick one.
ALL my boats - ALL my maintenance - of EVERYTHING I own......done right.
Who do you want working on your boat/car/sled......?
