An Inspector from NSTB who was visiting RSA in Nov/Dec 2004 had a look at the engine and prop (now here in RSA) and determined that only the Prop and Shaft needed to go to USA.
There then followed 3 months (!!!) of beaurocratic confusion with the various DCA's and the part finally left RSA for the USA last week.
So we still have some way to go, but I will keep the forum posted as things progress.
