Honeywell TPE331-12JR
The Honeywell TPE331-12JR is a turboprop model documented in Cessna Caravan engine conversions. Honeywell describes Alaska Seaplanes replacing the original engine of a Grand Caravan with a 900 hp -12JR under a Texas Turbine Conversions supplemental type certificate, improving performance for demanding Alaskan operations. That example establishes a specific conversion and operating context; it does not make every TPE331 variant or Caravan installation equivalent.
