The Quest Kodiak is an American utility aircraft built by Quest Aircraft. The high-wing, unpressurized, single-engine turboprop has a fixed tricycle landing gear and is suitable for STOL operations from unimproved airfields.

Design began in 1999, it made its maiden flight on October 16, 2004 and was certified on 31 May 2007 before first delivery in January 2008. By 2018, 250 were delivered.

Development[edit]

Engineering design began in 1999, while the company organization was being finalized.[1] The design was type certified by the US Federal Aviation Administration on 31 May 2007.[4]

In June 2010, Wipaire, Inc. was granted Supplemental Type Certification allowing Wipline 7000 Amphibious Floats to be installed on Kodiaks.[5] 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.[6]

In 2014, an executive "Summit interior" with club seating was introduced.[7] In April 2017, The Kodiak received its type certificate from the European Aviation Safety Agency.[8]

In May 2018, Quest Aircraft unveiled the Series II, priced at $2.15 million. The airframe has improved cargo door step mechanism and wing root sealing, new crew door stays, optional single-point refueling and new paint schemes. The cockpit has compact backup instruments, a faster Garmin G1000 NXi with HSI map displaying traffic, terrain, weather, navaids, and obstacles and an MFD showing terrain, usable for weight and balance and permitting autopilot visual approaches.[3]

Design[edit]

The utility aircraft can accommodate more than 10 people. It features aluminum construction, with short-field capability, and good useful load.[9] Its STOL performance comes from a fixed, discontinuous leading edge on the outboard wing and the 750 hp (559 kW) Pratt & Whitney Canada PT6A-34 turboprop engine. 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).

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 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.[14] The 250th was delivered in 2018, as the highest time aircraft surpassed 5,000 hours.[2]

Variants[edit]

Kodiak 100
Base model, FAA certificated 31 May 2007.[4]
Kodiak 100 Series II
Model introduced in May 2018, incorporating improvements, including a Garmin G1000NXi avionics suite, Flight Stream 510 tablet connection device, an angle-of-attack indicator and a digital standby four instrument group.[15]
Air Claw
A surveillance modification by Northrop Grumman with a FLIR systems Star Saphire sensor and a Persistent Surveillance Systems Hawkeye wide area sensor.[16]

Operators[edit]

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.[17] Setouchi was the Quest dealer for Japan and purchased Quest Aircraft in 2015.[18]

In November 2017, 220 Quest Kodiaks are flying worldwide as freighters, for skydiving and as business aircraft.[19]

India's SpiceJet intends to buy 100 amphibious Kodiaks, a $400 million deal. It has applied for financial support from Narendra Modi as part of the national aviation expansion program UDAN (Ude Desh Ka Aam Naagrik, “Let Every Person Fly”) for connecting its population by air, despite limited infrastructure. As only 3% of Indians travel by air, it is hoped that the Kodiak will stimulate air travel by operating from waterways and unimproved runways. The aircraft has been demonstrated as a landplane and seaplane demonstrations will happen next. Aerocet carbon-fiber amphibious floats are a $400,000 option.[19]

Accidents[edit]

By October 2018, there had been 16 Kodiak aviation accidents and incidents reported in the Aviation Safety Network database, including five hull-losses and three lethal accidents, causing five fatalities.[20]
