==Development==
'''Evektor EV-55 Outback''' is a twin-engine turboprop aircraft that was designed and is built in the [[Czech Republic]] by [[Evektor-Aerotechnik]]. The prototype first flew in June 2011.<ref>Stephen Pope, ''Evektor EV-55 Makes First Flight'', [[Flying (magazine)|Flying]], September 2011, p. 20</ref>
In 2004 the company announced its plan to design and construct a two-engined utility aircraft that would carry up to 14 passengers or 4000&nbsp;lb (1800&nbsp;kg) of cargo, and operate from unimproved fields and at high-altitude airports.


The first prototype, an EV-55M (military version), flew from [[Kunovice Airport]] in June 2011, with company pilot Josef Charvat and military pilot Maj. Jiri Hana at the controls.<ref name="EV55News"/>
==Design and development==
It was estimated at $2.1 to $2.2 million in 2012.<ref>{{cite news |url= http://www.aopa.org/News-and-Video/All-News/2012/March/5/SmartDeck-panel-added-to-Evektors-new-turboprop-twin |title= SmartDeck panel added to Evektor's new turboprop twin |publisher= [[Aircraft Owners and Pilots Association|AOPA]] |date= 5 March 2012}}</ref>
In 2004 the company announced its plan to design and construct a two-engined utility aircraft that would carry up to 14 passengers or 4000 lb (1800 kg) of cargo, and operate from unimproved fields and at high-altitude airports. The aircraft will have three configurations: passenger transport, cargo transport and combined operations with space in front for cargo and passenger accommodation aft.
The first production-conforming aircraft flew from Kunovice in April 2016.<ref name=Flying14April2016>{{cite news |url= http://www.flyingmag.com/evektor-flies-first-production-conforming-ev-55 |title= Evektor flies first production-conforming EV-55 |magazine= Flying |date= 14 April 2016}}</ref>


In June 2018, its price was $4 million and two aircraft should finish development flights with 200 hours in 2016, for 500 total hours.<!-- <ref name=Flight14june2016/>-->
The EV-55 is of conventional high-wing utility design, with its [[Tailplane|horizontal stabilizer]] mounted near the top of its [[Vertical stabilizer|fin]]. The prototype aircraft is powered by two [[Pratt & Whitney Canada PT6#Variants|Pratt & Whitney PT6A-21]] turboprop engines (536 shaft horsepower), each driving a four-blade propeller. The wing is mounted atop a nearly-square fuselage, which has five windows per side. The trailing-link tricycle landing gear retracts into the nose section or pods on the lower fuselage. Expected maximum cruise speed is 220 knots (407 kph).
Evektor secured enough investment to complete the certification process scheduled for 2017, with a minority investment from a [[Malaysia]]n company backed by the country's former premier [[Mahathir Mohamad]], but not to begin full production.<ref name=Flight14june2016/>


The project's development was suspended on 16 March 2017 due to "some uncertainties" with Evektor's Malaysian investor.<ref>{{cite press release |url= http://www.evektor.cz/en/news/ev-55-outback-project-information#.Wd27FEtJa00 |title= EV-55 Outback project information |date= 16 March 2017 |publisher= Evektor |access-date= 11 October 2017 |archive-date= 11 October 2017 |archive-url= https://web.archive.org/web/20171011130406/http://www.evektor.cz/en/news/ev-55-outback-project-information#.Wd27FEtJa00 |url-status= dead }}</ref>

By December 2018, it was touted as a basis for an EVE-55 [[hybrid electric aircraft]] conversion to fly in 2020, with only one PT6A-21 running a {{cvt|400|kW}} generator in the rear compartment, for much lower noise, an 18% fuel saving and the same payload and performance: a 3 hours endurance and 40 minutes from electric power only.<ref>{{cite web |url= http://konference.org/vyvoj_leteckeho_prumyslu_2018/prezentace_recniku/Berchtold.pdf |title= EVE-55 - The Future Strategy of Evektor |author= Dr. Gerd Berchtold |date= 4 December 2018 |publisher= Evektor Group }}</ref>

==Design==
The EV-55 is of conventional high-wing utility design with a [[T-tail]]. The prototype aircraft is powered by [[Pratt & Whitney Canada PT6#Variants|Pratt & Whitney PT6A-21]] turboprop engines (535 shaft horsepower), driving four-blade propellers.

Expected maximum cruise speed is 220 knots (407 km/h).<ref name=Flying14April2016/>

With nine passengers, range is 800nm (1,480km), it can take-off in 410m and land in 520m and with more speed, range and short take-off and landing capability, it can replace ageing piston-twins like the [[Cessna 421]] and [[Britten-Norman Islander]], or the smaller [[Cessna Caravan]] single turboprop when the [[payload-range]] of a larger turboprop such as the [[L-410]] or Viking [[Twin Otter]] is not needed.<!--<ref name=Flight14june2016/>-->

The Evektor EV-55 Outback is a twin-engine turboprop aircraft designed and built in the Czech Republic by Evektor-Aerotechnik. The prototype first flew on 24 June 2011.[2][3] The project's development was suspended in March 2017.

Development

[edit]

In 2004 the company announced its plan to design and construct a two-engined utility aircraft that would carry up to 14 passengers or 4000 lb (1800 kg) of cargo, and operate from unimproved fields and at high-altitude airports.

The first prototype, an EV-55M (military version), flew from Kunovice Airport in June 2011, with company pilot Josef Charvat and military pilot Maj. Jiri Hana at the controls.[3] It was estimated at $2.1 to $2.2 million in 2012.[4] The first production-conforming aircraft flew from Kunovice in April 2016.[5]

In June 2018, its price was $4 million and two aircraft should finish development flights with 200 hours in 2016, for 500 total hours. Evektor secured enough investment to complete the certification process scheduled for 2017, with a minority investment from a Malaysian company backed by the country's former premier Mahathir Mohamad, but not to begin full production.[1]

The project's development was suspended on 16 March 2017 due to "some uncertainties" with Evektor's Malaysian investor.[6]

By December 2018, it was touted as a basis for an EVE-55 hybrid electric aircraft conversion to fly in 2020, with only one PT6A-21 running a 400 kW (540 hp) generator in the rear compartment, for much lower noise, an 18% fuel saving and the same payload and performance: a 3 hours endurance and 40 minutes from electric power only.[7]

Design

[edit]

The EV-55 is of conventional high-wing utility design with a T-tail. The prototype aircraft is powered by Pratt & Whitney PT6A-21 turboprop engines (535 shaft horsepower), driving four-blade propellers. The wing is mounted atop a nearly-square fuselage, which has five windows per side. The trailing-link tricycle landing gear retracts into the nose section or pods on the lower fuselage. Expected maximum cruise speed is 220 knots (407 km/h).[5]

With nine passengers, range is 800nm (1,480km), it can take-off in 410m and land in 520m and with more speed, range and short take-off and landing capability, it can replace ageing piston-twins like the Cessna 421 and Britten-Norman Islander, or the smaller Cessna Caravan single turboprop when the payload-range of a larger turboprop such as the L-410 or Viking Twin Otter is not needed. The less expensive, unpressurised EV-55 won't compete with the Pilatus PC-12 or Beechcraft King Air. [1]

The 5.02m x 1.61m cabin standard layout is five and four seats with a cargo compartment separated by a semi bulkhead and a L-410 sized double door at the rear. It is equipped with a full glass cockpit, Czech firm Avia makes the four-blade propellers and Aero Vodochody the landing gear.[1]
