Cessna 208 Caravan

The Cessna 208 Caravan is a utility aircraft produced by Cessna. The project was commenced on November 20, 1981, and the prototype first flew on December 9, 1982. The production model was certified by the FAA in October 1984 and its Cargomaster freighter variant was developed for FedEx. The 4 ft (1.2 m) longer 208B Super Cargomaster first flew in 1986 and was developed into the passenger 208B Grand Caravan.

Not to be confused with Cargo Dragon C208.

On November 20, 1981, the project was given a go-ahead by Cessna for its Pawnee engineering facility. John Berwick, chief engineer at Pawnee, came with a concept of a single engine, high-wing airplane with a large payload. Berwick had originally approached VP Bill Boettger with the idea and once Dwane Wallace approved it, Berwick told Russ Meyer he would design it.[2]

The prototype first flew on December 9, 1982.[3] The production model was certified by the Federal Aviation Administration (FAA) in October 1984.[4] A freighter variant without cabin windows was developed at the request of Federal Express as the Cargomaster.[4] Another cargo variant for Federal Express, with a longer fuselage and a cargo pod under the belly, was developed as the 208B Super Cargomaster and flew for the first time in 1986.[4] FedEx was initially planning to build twin-engine piston-powered airplanes with Piper Aircraft, but picked the Caravan after surveying it and having flown the prototype, becoming its standard carrier.[2]

A passenger model, the 208B Grand Caravan, was derived from the Super Cargomaster.[4] Since then, the Caravan has undergone a number of design evolutions, including upgrading the avionics in 2008 to provide a glass cockpit with the Garmin G1000 system.[5] In January 2013 a higher-powered (867 shp from P&WC PT6A-140) version, the Grand Caravan EX, received FAA certification.[6]

In August 2016, Textron announced that it would move the Cessna 208 production line from its Wichita headquarters to its Independence, Kansas production facility, for manufacture alongside along the piston-powered 172S Skyhawk, 182T Skylane, T206H Turbo Stationair and Cessna TTx; and the Citation M2 light jet. The move was made to make room for production of the Citation Longitude and Denali in Wichita.[7]

Chinese production

In May 2012 Cessna announced that an assembly line for the 208 would be established in China, with the government-owned China Aviation Industry General Aircraft (CAIGA) conducting final assembly of Caravans at its plant in Shijiazhuang for the Chinese market.[8] Chinese government approval was granted in September the following year and the first Chinese-assembled Caravan was delivered in December 2013.[9][10] By April 2016 about 30 aircraft, assembled from kits of parts shipped from the US by Cessna, had been delivered to Chinese operators by the joint venture.[11]

Design
Low-density seating in the cabin of a passenger-carrying version

The Cessna 208 is a high-wing braced cabin monoplane powered by a single Pratt & Whitney Canada PT6A turboprop in tractor configuration. The cabin has room for nine passengers and two crew when used as a passenger aircraft with four doors: one for each crew member, an airstair door on the right side of the cabin and a cargo door on the left. The aircraft can be optionally fitted with an underslung cargo pod.

The basic 208 airframe has a fixed tricycle landing gear but can also be fitted with various types of landing gear, allowing it to operate in a wide variety of environments. Some common adaptations include floats with retractable landing gear on the Caravan Amphibian model, and skis.[4]

The Caravan interior can be outfitted with seats or as a cargo compartment. The standard high-density airline configuration has four rows of 1-2 seating behind the two seats in the cockpit. This variant is capable of holding up to thirteen passengers, although it is marketed as being able to make a profit carrying just four.[12] The cabin can be configured in a low density passenger configuration, with 1-1 seating, as a combination of passengers and cargo, or as a strictly cargo aircraft.[13] Many variants include an underbelly cargo pod, which can be used for additional freight capacity, or for passenger baggage. A number of Caravans are operated as skydiving aircraft with the left-side cargo hatch converted to a roll-up door.[14]

The airplane typically seats nine passengers with a single pilot, although with a FAR Part 23 waiver it can seat up to fourteen passengers. The aircraft is also used for cargo operations.

Variants

Civilian
208 Caravan
First production variant with a PT6A-114 turboprop engine and seating for up to nine passengers. The landplane variant was type approved on October 23, 1984 and the seaplane version with Wipline Model 8000 Amphibious/Seaplane Floats was type approved on March 26, 1986. Early aircraft can be modified to use the higher-powered PT6A-114A but have restricted operating limits.
  • 208 Caravan 675
Marketing designation for the 208 Caravan with a higher-powered PT6A-114A engine.
A FedEx 208B Super Cargomaster
208A Cargomaster
A pure-cargo version of the Caravan developed with Federal Express (now FedEx); 40 aircraft produced.[15] All 208A aircraft were serialized as 208 models.
208B Grand Caravan in Mexico with its right rear airstair door open. The 208B Grand Caravan is 4 feet (1.2 m) longer than the 208 and the passenger-carrying version has eight side windows instead of the 208's six.
208B Grand Caravan
Officially named the 208B Caravan but marketed as the Grand Caravan. The 208B is 4 ft (1.2 m) longer than the 208; extending the cabin by the same amount. The 208B has a PT6A-114A engine. It was originally certified as a two-seater cargo version on October 9, 1986 and as an 11-seater passenger aircraft on December 13, 1989.
  • 208B Grand Caravan EX
Marketing name for upgraded version of the 208B Caravan certified in December 2012, with a more powerful 867 hp (647 kW) Pratt and Whitney Canada PT6A-140 that improves the rate of climb by 38% and was developed by Pratt & Whitney Canada specifically to power the 208B.[16][17] The unladen weight is 807 lb (366 kg) more but maximum payload is only 90 lb (41 kg) more. While the 192 hp (143 kW) more powerful PT6A-140 gives a 11-knot (20 km/h) higher cruise speed – and rate of climb is improved by 94 feet per minute (0.48 m/s), range is reduced to 964 nautical miles (1,785 km) on a similar fuel capacity. It requires a longer take off run at 2,160 feet (660 m) and its landing roll is at 1,871 feet (570 m).[18] In early October 2019, after just under six years in production, the company had delivered 500 Grand Caravan EXs.[19]
  • 208B Super Cargomaster
