The Quest Kodiak is an American high-wing, unpressurized, single-engine turboprop-powered fixed tricycle landing gear utility aircraft built by Quest Aircraft, suitable for utility applications on unimproved airfields. A skydiving version has been certificated.

The Kodiak is intended more for the utilitarian market, although an executive "Summit interior" with club seating was introduced in 2014.[4]

Design and development[edit]

Engineering design began in 1999, while the company organization was being finalized.[1] The goal was to create a utilitarian vehicle capable of carrying 10+ people, using aluminum construction, short-field capability, and good useful load.[5] Large contributors to the Kodiak's STOL performance are a fixed, discontinuous leading edge on the outboard wing and the high performance Pratt & Whitney Canada PT6A-34 turboprop engine of 750 hp (559 kW).

Passenger seats in the Kodiak are track-mounted and easily removed. It has standard access doors for pilot and co-pilot positions, with a clamshell door (48.5" × 50") in the aft fuselage for cargo loading or for access to the other eight passenger positions (the lower half of the clamshell door has automatically extending/retracting steps).

The design was type certified by the US Federal Aviation Administration on 31 May 2007.[6] In June 2010, Wipaire, Inc. was granted Supplemental Type Certification allowing Wipline 7000 Amphibious Floats to be installed on Kodiaks.[7] In November of that same year it was also certified for flight into known icing after the installation of a TKS system, which protects exposed surfaces via glycol-based fluids.[8] The Kodiak received its type certificate from the European Aviation Safety Agency in April 2017.[9]

Operational history[edit]

The first Kodiak was delivered to launch customer Spirit Air in January 2008.[10] By September 2013, 100 Kodiaks had been built, with the 100th aircraft being delivered to US operator Sunstate Aviation.[11] The Kodiak was designed for use by mission societies, and several aircraft have been delivered to organisations such as Mission Aviation Fellowship and JAARS.[12][13] Some of the Kodiaks built have been produced under Quest Aircraft's Quest Mission Team (QMT) program.[13] The QMT program aims to sell one of every 11 Kodiaks built to a mission organisation at cost price.[13]

The largest single order was announced on 15 November 2016 for 20 aircraft from Sky Trek, to be delivered within a year. Tokyo-based Sky Trek plans to begin air charter services in the first half of 2017 and is a start-up membership-based operator owned by Mitsui and Setouchi Holdings.[14] Setouchi was the Quest dealer for Japan and purchased Quest Aircraft in 2015.[15]

The 200th aircraft was delivered in December 2016 for a record yearly production of 36 Kodiaks, while the production facility was extended by 25 percent in September to cope with growing demand.[2]
