Turbine Bonanza (A36 conversion)

Built 1986Out of production1 pilot

A turbine engine swap for the six-seat Beechcraft A36 Bonanza, sold as an aftermarket conversion.

58JetGrade70 = typical for turboprops

One of the cheapest ways into a turbine single, and a fast, climb-happy Bonanza for one or two people. With full fuel it carries the pilot plus one or two passengers, the cabin is unpressurized, and conversion support now rests with one small company.

Buy it if

You fly yourself, usually alone or with one passenger, on trips under about 600 nm, and want a turbine engine, jet fuel, strong climb and 200-plus knots in a familiar Bonanza airframe.

Skip it if

You regularly carry three or more adults with bags, want a pressurized cabin, need legs beyond about 500 nm with passengers, or want factory support and quick resale.

Biggest compromise

Weight. The conversion adds 40 gallons of tip-tank fuel and raises maximum takeoff weight to 3,833 lb only when those tips hold fuel.

  • Piper Meridian (PA-46-500TP) instead: Pressurized cabin and about 260 knots, at roughly two to four times the asking price and nearly double the fuel burn.
  • Cessna P210 Silver Eagle (conversion) instead: A related Rolls-Royce 250 turboprop conversion on a pressurized Cessna 210, for buyers who want to fly high without masks.
  • Piper PA-46 JetPROP DLX instead: A pressurized Malibu with a Pratt & Whitney PT6 turboprop, for buyers who want turbine power and a cabin that flies high.

  • Engine hot section · 1,750 hr
  • Propeller overhaul · 3,000 hr
  • Engine overhaul · 3,500 hr
  • Annual inspection every 12 months

Rolls-Royce sells its pay-per-hour plan to helicopter operators; owners of this airplane usually set money aside for overhaul.

Known issues

  • Small support base

    The original converter closed; conversion parts and manuals now come from Soloy, one small company.

  • Hot starts damage turbines

    A hot start can crack turbine wheels; one in-flight engine failure was traced to earlier hot starts.

  • Fuel planning margin

    About 25 gallons an hour against 114 gallons gives roughly four hours; one fatal accident followed fuel exhaustion.

Pre-buy checklist

0 of 9 checked

Engine parts and overhaul shops are plentiful because the same engine family powers many helicopters. Conversion-specific parts and manuals come from Soloy Aviation Solutions, now owned by NorthPoint Aviation in Minnesota.

Review

The full review

Strengths

  • Cruises at 200–215 knots in the mid-teens, about 50 knots faster than a piston A36 Bonanza.
  • Burns about 24–27 gallons an hour, roughly half the fuel of a TBM 700 or Piper Meridian.
  • Reversing three-blade propeller and climb rates up to about 2,500 feet per minute suit short runways.

Limitations

  • Full-fuel payload is about 440 lb after the pilot in a lightly equipped example, and less in heavier ones.
  • Unpressurized: best speeds come at 15,000–17,000 ft, where everyone aboard needs supplemental oxygen.
  • The original converter closed; conversion parts and manuals now come from one small company, Soloy.

The Turbine Bonanza is a Beechcraft A36 Bonanza, the six-seat piston single built from 1970 to 2005, with its Continental piston engine replaced by a Rolls-Royce (originally Allison) 250 turboprop. Soloy and Allison certified the first version in 1986 with a 420 shp engine. Tradewind Turbines of Amarillo, Texas, bought the program in 1989 and made the 450 shp 250-B17F/2 the standard engine, which is why the airplane still carries the Tradewind name. The conversion applies to 1979-and-later A36s and adds a nose 21 inches longer, two 20-gallon tip tanks and a three-blade reversing propeller. Only a few dozen were converted.

Pilot's take

We would treat it as a fast two- or three-seat airplane that happens to have six seats. The turbine changes the experience: smooth power, quick climbs and a reversing propeller for short runways. The discipline changes too. Starts need close attention to temperature, because hot starts can damage the turbine, and fuel planning needs margin, since roughly four hours of endurance goes quickly at low altitude where the burn rises. Weigh the actual airplane before planning trips, plan oxygen for the mid-teens, and get turbine transition training before flying it alone.

— TheJetGrade editorial

Who this is for

An experienced Bonanza owner-pilot who flies mostly alone or with one passenger, values turbine smoothness and quick climbs over cabin size, and can budget for an engine overhaul and a thin resale market.
