Part 1, the heart of the matter.

A bold presence, this Cessna T207 rolls into AVSTAR after an avionics update for a new engine.  This aircraft is now destined to operate in the San Juan Islands of Washington State, performing primarily low altitude work.  The tired TSIO-520 engine is not part of the continuing story for this aircraft.













Aside the usual loose rivets and minor sheet metal work normally encountered at an engine change, the turbo was to be omitted and the exhaust returned to normally aspirated configuration.  So, we had a hole to fill.....







...and more holes to make.










The finished product includes a new air induction system as well as the exhaust due to loosing the turbocharger, so it is less busy under the cowl.  Also, you may note another addition; a B&C stand-by alternator has been added.  Oh yes, let me not forget to tell you this installation is an IO-550 now; the STC holder for this, as well as supplier of the conversion kit is Davis Aviation, of Bristol, TN.

The transformation continues in part 2, body building.
