Starting mid of February reaching up to beginning of May 2021 our Cessna Grand Caravan C208B has been in the workshop. The background to this lengthy stay was a pleasant one: We exchanged the Pratt & Whitney standard engine PT6A-114A against the externally nearly identical PT6A-140. Why all of that? Because we could increase the performance of the engine from 675 shp to 867 shp. This resulted in a significant increase for dropping operations! We are achieving nearly identical turn-around times like the Garrett conversions. Same time we massively reduced noise emissions: We are flying now in the best noise protection category! By this we also have unrestricted access to European airfields.
