The PT6A Powered Embraer EMB-110 Bandeirante

The success of the first two prototypes of the EMB 100, built by the team of the then CTA (Technical Aeronautics Center) under the leadership of Ozires Silva, gave the engineers the challenge of mass production and commercialization of the aircraft. As such, the Federal Government officially created Embraer on August 19, 1969.

New Business Turboprops 2019

Wither the new turboprop market, or the pause that refreshes? Historically, new business turboprop sales remain relatively steady while jet sales gyrate up or down. So far, this year is a little different. While new business jet deliveries have climbed more than 12 percent for the first six months of 2019, turboprop deliveries dropped 11.2 percent for 1H 2019 compared to the year-ago period, according to data from the General Aviation Manufacturers Association (GAMA). It is notable that a big chunk of jet sale gains were models that challenge traditional turboprop territory, such as the new Cirrus SF50 single-engine jet or the revised HondaJet Elite light twin.

DHC-7: The quiet STOL multi-tasker

Article first seen in Skies Magazine here.

Fifty years ago, de Havilland Canada (DHC) was the global leader in the design and production of STOL (short takeoff and landing) aircraft. Beginning with the DHC-2 Beaver in 1947 and following with the DHC-3 Otter, DHC-4 Caribou and DHC-5 Buffalo, the Toronto-based company had developed a family of ever-larger airplanes that could access isolated locations — with or without a runway.

A Look at Pilatus Aircraft & A List of Aircraft the Company has Produced

The Company was established in the early 1940s, the first design project was a single-seat trainer, designated P-1 but it was abandoned before being built. The next project was the SB-2 Pelican which was designed by the Swiss Federal Institute of Technology but it never was built in series. 
With production of the P-3 for the Swiss Air Force in progress, the company achieved its first export order for six P-3s for the Brazilian Navy.

In 1958 design work started on a STOL light civil transport aircraft, this emerged as the PC-6 Porter which first flew on 4 May 1959. In 1965 a twin-engined variant of the PC-6 was built as the PC-8 Twin Porter, although it first flew on 15 November 1967 it remained an experimental and one-off type and development was stopped in 1972. 

Another project for the PC-10 16-passenger twin-engined transport was started but was not built.

Pilatus PC-6

The Pilatus PC-6 Porter is a single-engined STOL utility aircraft designed by Pilatus Aircraft of Switzerland. First flown in 1959, the PC-6 continues in production at Pilatus Flugzeugwerke in Stans, Switzerland. It has been built in both piston engine- and turboprop-powered versions and was produced under licence for a time by Fairchild Hiller in the United States. After around 600 deliveries in six decades, Pilatus will produce the last one in early 2019.

In 1966 a turboprop-powered variant of the P-3 was flown, designated the PC-7. 

The aircraft crashed and development was put on hold until the 1970s. In 1975 a further prototype was flown and after further development ,it was marketed as the PC-7 Turbo Trainer.

In 1982 development of an improved variant of the PC-7 was started, it emerged as the Pilatus PC-9 in 1984. Development of what was to become the companies best selling type the Pilatus PC-12 was started in 1987, a single-engined turboprop transport that could carry up to twelve passengers or freight. The prototype PC-12 was flown on 31 May 1991.

To further the family of military training aircraft the turboprop PC-21 was developed and first flown in 2002.

In December 2000, the owners Unaxis (previously called Oerlikon-Bührle) sold Pilatus to a consortium of Swiss investors. In July 2010 the company delivered its 1000 PC-12.

Even in the last years of crisis, Pilatus still confirmed the leadership on this nice market with the help of loyalty versus this Swiss company that delivered excellent products all over the world with many orders of their products like PC-7 MkII, PC-12 NG and PC-21. 

Pilatus announced last years the development of their first Jet-engine aircraft that should be fly for the first time in 2013 or beginning of 2013, at the moment the official name should be PC-24.
