Hey guys,
Here is one for you. Got a 180 in for annual, and it has a freshly overhauled 470-50. It was a TSIO-520-P converted via the STC to be a 470-50 (520 C.I.) While doing an AD search I came across the VAR crank Ad 97-26-17 says at overhaul or whenever the crank is removed from the engine to replace it with a VAR Crank. Northpoint when I called said well its technically a grey area and because its technically a 470 that AD doesn't apply to it. Whats the consensus? Am I over thinking it? Just trying to cover my a$s. Seems like if I was overhauling one that is a 520 and the only change is fuel delivery I would have changed cranks, but maybe I'm using too much logic?
Thanks
