Perm Engine Company has been granted permission for modular repair of PS-90A engine

Perm November 25, 2011 The airworthiness safety arm of Federal Air Transport Agency (Rosaviatsia) has confirmed and activated a Statement opening the way for the Perm Engine Company to launch PS-90A engine into use by replacing modules in the high pressure turbines (HPT).

The activation of this Statement is essential in order to arrange repair of aviation engines of this construction in the shortest possible time in the airlines own facilities, without the need to send them back to the factory. Replacing HPT modules by PS-90A engines can be done in the hangar on a special repair stand, which must be certified and meet all technical requirements pertaining to PS-90A engine.

To date, HPT modules have already been replaced on five PS-90A-76 engines at two airlines  Volga-Dnepr and Silk Way Airlines  who pioneered the use of the modular principle. The work was done with the help of a certified team made up of seven Perm Engine Company specialists. It takes about 15-20 days to rebuild one engine with modular HPTs.

Alexei Mikhalyov, managing director of OJSC Perm Engine Company:

"Replacing modular units allows us to significantly reduce time and expense of engine repair. The high-pressure turbine is best suited to the stress of the working engine, but is also the most difficult to repair. Currently, it has to be sent back to the manufacturer, causing unnecessary loses for the factory and the airline as well.

In addition, organizing repairs on a modular system would not be possible without a great deal of preparation at the factory. The Perm Engine Company has taken on the primary responsibility for ensuring the unsurpassed quality of each component of the replacement unit, so that the engine, once repaired, will meet all requirements fully.

Our short-term plans are to build a PS-90A engine repair and modification unit in Russian main aviation hub  Moscow. Such units are already ready to launch in Baku (Azerbaijan), Havana (Cuba) and Ulyanovsk. In the near future we are ready to repair 16 malfunctioning engines belonging to various airlines, using the modular repair technology.

Perm Engine Company OJSC mass produces aviation engines for civil and military applications, as well as industrial gas turbine units for power stations and gas transportation.

PMZ OJSC is a part of United Engine Corporation Management Company OJSC, a wholly-owned subsidiary of OBORONPROM specializing in engine-building assets.
