DHC-6 Twin Otter Series 100, 200 and 300

Built 1965–1988Out of production1 pilot

The original 1965–1988 Twin Otters; the Series 300 is the final and most common version.

66JetGrade70 = typical for turboprops

Few aircraft can carry 19 passengers into short strips, onto lakes or onto snow as dependably. But it is slow, unpressurized and old, and well-kept or rebuilt examples cost far more than their age suggests.

Buy it if

You need to move up to 19 people or about 2,500 lb of cargo into short, rough, wet or snowy places, and you value two engines and continuing factory parts support.

Skip it if

You mainly want a fast, comfortable cabin for business trips over 500 nm. A pressurized turboprop or a light jet covers the same distance much faster, above most weather.

Biggest compromise

Speed and comfort. At about 160 to 182 kt in an unpressurized cabin under 5 ft tall, a 600 nm trip takes about four to five hours, often with oxygen or a fuel stop, and most cabins hold 19 commuter seats, typically with no lavatory or galley.

  • Cessna Grand Caravan 208B instead: Single engine and fewer seats, but flown by one pilot, typically cheaper to run and very widely supported.
  • Viking DHC-6 Twin Otter 400 instead: The modern Twin Otter: the same proven airframe built new from 2010, with PT6A-34 engines and a glass cockpit.
  • Beechcraft 1900C instead: A pressurized 19-seat twin that cruises far faster and flies much farther, but needs longer, better runways.

Pratt & Whitney Canada lists a 2026 flat-rate PT6A-27 overhaul at $372,000 per engine; the older PT6A-20 is not on that list.

Known issues

  • Control cable wear

    Elevator, rudder and aileron cables are life-limited and covered by several directives; one cable failure caused an accident.

  • Structural life limit

    Airframes are limited to 66,000 hours or 132,000 cycles; high-time aircraft need major Re-Life structural work.

  • Wing spar adapter cracking

    Stress-corrosion cracking requires checks every 1,200 hours or 12 months until the improved part is fitted.

Pre-buy checklist

0 of 10 checked

De Havilland Canada still supports the type with parts, factory-endorsed service centers and new Re-Life structural kits, and independent PT6 shops worldwide handle the engines.

Review

The full review

Strengths

  • Series 300 clears a 50 ft obstacle in about 1,200 ft with short-field technique and lands over one in 1,050 ft.
  • Seats 19 to 20 passengers, or carries about 2,500 lb over 700 nm, loaded through a large double cargo door.
  • Approved on wheels, tundra tires, skis, floats and amphibious floats, and De Havilland Canada still sells parts and life-extension kits.

Limitations

  • Cruises at about 160 to 182 kt, so a 600 nm trip takes about four to five hours.
  • Unpressurized cabin only 4 ft 11 in tall; higher cruising altitudes require supplemental oxygen.
  • Built between 1965 and 1988, with life-limited structure, several cable and corrosion directives, and few published prices.

The de Havilland Canada DHC-6 Twin Otter is a high-wing, twin-turboprop utility aircraft that first flew in May 1965. This page covers the original production run of 844 aircraft built until December 1988: the Series 100, the Series 200 with its longer nose and bigger baggage areas, and the Series 300, which makes up most of the fleet. Viking Air restarted production in 2010 with the Series 400, and the type certificate now sits with De Havilland Aircraft of Canada, which delivered the 1,000th Twin Otter in March 2026.

Pilot's take

This is an aircraft that rewards technique more than speed. On a short strip, full flaps, careful speed control and reverse thrust bring it to a stop in remarkably little room, and two PT6s give a second engine over water or forest. Systems are simple and the landing gear is fixed. Icing deserves respect: the flight manual requires early boot use and leaving severe icing promptly. Expect to plan around oxygen, fuel stops and weather rather than over it.

Who this is for

Island, bush, float and polar operators, skydive centers, survey and government fleets, and owners of remote lodges who need a rugged twin that carries a crowd almost anywhere and accept slow, simple travel.
