Cheyenne I / IA (PA-31T1)

Built 1978–1984Out of production1 pilot

The lower-power, lower-price member of Piper's PA-31T Cheyenne family, built from 1978, with the rare IA following in 1983–1984.

66JetGrade70 = typical for turboprops

The Cheyenne I is the cheapest way into a pressurized twin turboprop: about 240 knots, roughly 900 nm with four aboard and only about 65 gallons an hour. The price is a tight cabin, scarce PT6A-11 engine parts and few specialist shops.

Buy it if

You are stepping up from a piston twin, fly yourself or with one pilot, usually carry four or fewer, and want two turbine engines and flight-level comfort for under $500,000, with a Cheyenne-savvy shop within reach.

Skip it if

You routinely fill every seat, want stand-up headroom or a private toilet, fly too few hours to fund an engine overhaul reserve, or need overnight parts support far from a Cheyenne specialist.

Biggest compromise

Piper cut the price by fitting smaller 500 shp PT6A-11 engines that few other aircraft use. Exchange engines and parts are harder to find than for a King Air, and two overhauls can cost more than the aircraft is worth, which is why many owners have paid to upgrade to newer PT6A-135A or PT6A-28 engines.

What changed from the Cheyenne / Cheyenne II (PA-31T)

  • 500 shp PT6A-11 engines replaced the Cheyenne II's 620 shp PT6A-28s.
  • Lower power removed the need for the tail stability augmentation system.
  • Tip tanks became optional: 300 gallons standard, 382 gallons with tips.
  • The aft center-of-gravity limit moved 2 in forward.
  • It cost about $100,000 less new than the 620 shp model.
  • The 1984 IA added reshaped intakes and longer exhaust stacks for more speed up high.

  • King Air C90 instead: A wider, taller cabin and the deepest parts and service network of any twin turboprop, for a higher purchase price and fuel bill.
  • Cheyenne II (PA-31T) instead: The same airframe with 620 shp engines and about 40 knots more speed, but it needs its tail stability system kept working.
  • Cheyenne IIXL (PA-31T2) instead: Two feet longer, more powerful and without the stability system; the Cheyenne to pick if you regularly fill seats and baggage bays.

Known issues

  • Scarce, costly PT6A-11 engines

    Few aircraft used the -11, so exchange engines are scarce; two overhauls can exceed the aircraft's value.

  • Tail structure directives

    Stabilizer bulkhead and elevator rib directives apply to early aircraft; confirm the fixes are done and logged.

  • Wiring fire directive

    Yearly inspection of wiring below the circuit breaker panel, introduced after a fatal in-flight fire.

PT6 engine shops are everywhere, but Cheyenne airframe expertise is concentrated in a few specialists such as Friend AirCare in Pennsylvania. Piper still supplies manuals and will make obsolete parts, sometimes slowly.

Review

The full review

Strengths

  • Burns about 65 gallons an hour while cruising near 240 knots, well below a King Air 90's fuel bill.
  • With the common tip tanks it carries four passengers roughly 900 nm, enough for Los Angeles to Denver nonstop.
  • Published guide values near $467,000–$495,000 make it one of the least expensive pressurized twin turboprops to buy.

Limitations

  • The cabin is 50 in wide and 51.5 in tall, and the wing spar crosses the floor behind the cockpit.
  • Its PT6A-11 engines have no factory flat-rate overhaul price, and exchange engines are scarce.
  • With full fuel in the tip tanks, only about 630 lb remains for people and bags after one pilot.

The Cheyenne I is the entry model of Piper's PA-31T Cheyenne family, a line of twin turboprops built on the airframe of the pressurized Navajo piston twin. When Piper introduced it in 1978, it took the original 620 shp Cheyenne, renamed that model the Cheyenne II, and created a cheaper version with smaller 500 shp Pratt & Whitney PT6A-11 engines. About 215 Cheyenne I and IA aircraft were built. The IA, certified in 1983 and built for only about a year, added redesigned engine intakes, longer exhaust stacks and standard wingtip fuel tanks; only about 20 were built.

Pilot's take

Pilots coming from a Navajo or other cabin-class piston twin tend to feel at home quickly: the Cheyenne I is stable, predictable and gentle in the stall, which comes at around 60 knots with everything down. The real learning is turbine discipline, from careful PT6 starts to single-engine procedures flown exactly by the numbers. Loading matters too, since the short cabin and aft seats can move the balance point quickly. Expect a steady 240 knots in the low flight levels rather than dramatic climb performance, and plan fuel stops on long trips with a full cabin.

— TheJetGrade editorial

Who this is for

An owner-pilot or small company moving up from a piston twin, flying regional trips of 300 to 700 nm with up to four passengers, who wants two turbine engines and pressurization and can base near a Cheyenne specialist.
