It appears your info is a little out of date as the event you are referring to happened in the 1st week of March, the engine was changed because it started producing low torque and high temps. A spare engine was shipped over to Orlando on a regular commericial flight so there was no need to charter anyone else's aircraft (the Tyne engines aren't that big anyway!)
Anyway the aircraft is currently airborne as I am writing this so no need worry anyone.
