autoalain Posted June 24, 2018 Report Share Posted June 24, 2018 My m20a with the guppy mouth, got a new cowl with the laser kit to make it smaller opening, so how would one get the paperwork (STC I guess)? another question the oil cooler on the new cowl has a back plate about 2 inches back of the fins, same size as the oil cooler, my m20a has no plate, what does it do? should I add it on the my present oil cooler.

Just call LASAR, explain the situation, and they will sell you the STC only, no parts. Have your A&P/IA file the paperwork. Not sure how this works in the great white north. Yes, I would use the plate behind the oil cooler. Quote Link to comment Share on other sites More sharing options...

Its not a waste of time to review the support data provided by Mooney from time to time. 1 Quote Link to comment Share on other sites More sharing options...
