I talked to an A&P about this and he said that its normally 2200 hours
or 12 years whichever comes first. Now the FAA wants to make it 2200
hours or 10 years and only for the blades with certain serial numbers.
Most of the ones he services never get past 5 years before he has to
change them anyway because of the hours.

OK. Then what's the MTBUR in hours on the blades? Or are you just
suggesting an unlimited retirement life? What has your "research" shown?

A DEPRESSION is when YOU are out of work.
A RECOVERY is when all the H-1B's are out of work."

them to put Americans out of work, visit the following
