AAR Indianapolis is doing the work and has been horribly slow and disorganized which contributed to the delays also.
|Quoting ChiGB1973 (Thread starter):|
We are also looking at the possibility of performing the upcoming D Check for L1011, tail number 194. Should the decision be made to perform this scheduled maintenance check, our desire is to replace the existing engines with newer 524B engines. No final decision has been made at this point.

Its just not as simple as replacing the RB211-22B engines with 524B engines. You would be creating a L-1011-200 i.e. L-1011-385-1-15, Lockheed has a Service Bulletin to accomplish this but you would have to pay them to add s/n 1230, N194AT, to the Service Bulletin effectivity list. To do this for just one aircraft only would be very expensive.

Given the difficulties that ATA has had finding suitable 767-300ER aircraft, I am wondering how NAA has managed to find two, for essentially the same mission that ATA was seeking them.
