The Antonov An-28 ( NATO code name : "Cash") is a passenger aircraft developed in the Soviet Union . It originated from the Antonov An-14 . The main differences are the use of propeller turbines and the larger cabin. The machine has STOL properties.
history
A prototype of the An-14 with a propeller turbine drive already existed. This was further developed and so the flight tests could be completed in 1972. Preparations for production of the actual prototype began in 1973. In April, the prototype received the 974 hp Gluschenko TWD-10 engines that were also intended for the series . Series production was outsourced to PZL Mielec , where the second prototype was completed in the summer of 1978.
Series production in Poland began with an initial order for 15 machines. 163 machines had been ordered by January 1, 1991.
construction
The aircraft, designed as a strutted shoulder- wing aircraft, is powered by two propeller turbines. The vertical tail is divided into two parts and is located at the end of the horizontal tail. The nose wheel landing gear is not retractable. The main landing gear wheels are on small stub wings. The machine is made entirely of metal. The cabin has no pressure ventilation .
Versions
There were attempts to use the Pratt & Whitney PT6A65B in 1991 . The An-28 PT variant equipped with it took off on its maiden flight in the spring of 1993. As the PZL M-28 Skytruck , the machines are manufactured in small numbers.
An extended variant of the An-28 has been developed as the Antonov An-38 .
Incidents
From the first flight in 1969 to November 2017, the An-28 / PZL M-28 suffered 32 total aircraft losses. 112 people were killed in 14 of them. Examples:
- On September 11, 2012, an Antonov An-28 operated by Petropavlovsk-Kamchatsky Air was flown against a mountain slope 10 kilometers from the airfield while approaching Palana on the Kamchatka Peninsula. 10 people were killed and 4 people survived. The crew had obviously been in the dark about their position, and both pilots were drunk (see also Petropavlovsk-Kamchatsky-Air flight 251 ) .
