When choosing the right Pilatus PC-12 to purchase, there are a few models to consider with many different series within each model. Pilatus has done a great job of constantly improving the PC-12 throughout its years. This article is aimed to explain the improvement made on each model and series.

The four PC-12 models are as follows:

PC-12/41 – 9,039 lbs. MTOW, PT6A-67B

PC-12/45 – 9,921 lbs. MTOW, PT6A-67B

PC-12/47 –10,450 lbs. MTOW, PT6A-67B

PC-12/47E(NG) – 10,450 lbs. MTOW, PT6A-67P


A couple things to consider when purchasing a Pilatus PC-12 are cost and performance. A popular, cost efficient strategy is to purchase a “Legacy” (pre /47E) aircraft, and upgrade it with the Finnoff engine conversion STC. The Finnoff engine STC upgrades the older 67B engine to the newer 67P engine, giving you up to 15 knots faster cruise and the performance similar to a NG, including dual direct drive 300-amp generators. There are many other upgrades that Pilatus has incorporated with their different “series” throughout the years.
