Honeywell TPE331-10
TPE331-10 is Honeywell's single-shaft turboprop model. Honeywell's model brochure lists 940 shp (about 701 kW) shaft output and 1,000 shp thermodynamic output, a 10.55 pressure ratio, 41,730 rpm gas-generator speed, and 1,591 rpm output-shaft speed; approved fuels include Jet A, Jet B, Jet A-1, JP-8, JP-1, JP-4, JP-5, and JP8+100. The record identifies the engine model; aircraft conversion and installation variants remain separately evidence-bound.
