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.[16]

India’s SpiceJet wants to buy 100 amphibious Kodiaks, a $400 million deal, hoping for financial support from Narendra Modi within the national aviation expansion program UDAN (Ude Desh Ka Aam Naagrik, “Let Every Person Fly”) for connecting by air its population despite limited infrastructure. As 3% of Indians travel by air, the Kodiak can stimulate air travel expansion by feeding it by operating from waterways and unimproved runways. It has been demonstrated as a landplane and seaplane demonstrations will happen next, Aerocet carbon-fiber amphibious floats are a $400,000 option.[2]
