Anyone reviewed the new proposed AD on rotor spindles? You can see it here:

They are proposing life limiting the spindles to 1500 hours, and are estimating a purchase and replacement cost of $18,690 per helicopter. In addition, an inspection would be conducted every 500 hours (so at 500 and 1000), with their cost estimate being $1,275/helicopter. So, if those costs are right this boosts the hourly operating costs by about $14USD.
I've been considering purchasing an older enstrom 280fx or f28f, but my current mechanic recommends waiting to see how this shakes out. What are your thoughts?
