Further more ALL maintence is done IAW. That's it. IAW. This means we done it all with approved data that is supplied.

These are the same people that said that American Airlines double there O/H on engines from the airforce. Once again I showed how the airforce hours for o/h was around 300 hours.

And your classic that it causes more problems than it fixes. Data. Where is your data to prove that.
