Perm Engine Company performs modular maintenance on the PS-90A engine

Perm/05.09.2012 At the end of August, the Perm Engine Company customer support department repaired a PS-90A engine by replacing the high-pressure turbines (HPT), on-site at Silk Way Airlines.

Replacing the HPT module of the engine was carried out by a team of six qualified specialists from PMZ with the help of certified equipment and units used in engine repair.

Perm Engine Company launched the practice of restoring engines by carrying out comprehensive repairs in situ in 2011. To date they have replaced the HPT modules on seven PS-90A-76 engines installed on Il-76TD-90 aircraft at two airlines  Volga Dnepr and Silk Way Airlines, pioneering this type of repair. This year the company plans to replace the HPT modules on 12 engines.

At present repair facilities in Ulyanovsk, Baku (Azerbaijan) and Havana (Cuba) are preparing to be certified in PS-90A engine restoration by means of modular replacement. In October 2012 the repair facility in another Russian city  Vladivostok  will be ready, based at the Vladivostok Avia airline. An agreement is in place to build similar facilities in Moscow (to service the aircraft of Red Wings airline) and in Agra (India).

The technology of repairing engines in situ at the base of operations without the need to send the engines back to the factory, created by Perm Engine Company and Aviadvigatel (developer of the PS-90A engine), allows the company to restore engines in a much shorter time. Restoring an engine by replacing the HPT module in situ takes just 15-20 days, while sending the engine back to the factory for repair takes at least 2-3 months.

AlekseyMikhailyov, Perm Engine Company managing director:

In 2011 during the hot season, the Perm Engine Company came under heavy criticism  airlines did not have reserve engines to replace those removed for repairs, and some aircraft were left without engines. This year this situation has not reoccurred. Today the Perm Engine Company is carrying out quite a high volume of repairs, creating a reserve of engines for airlines. The practice of restoring engines in situ at the operational site has shown itself to be effective. We have achieved particular success working with Volga Dnepr and Silk Way Airlines. If other airlines decide to carry out the same kind of work, then the efficiency of the PS-90A aviation engine will increase significantly.

SergeyMorzhenkov, vice president of Volga Dnepr Airlines:

We have a positive view of Perm Engine Companys initiative to repair aviation engines in situ at the base of operations by replacing separate modules. Modular repair allows us to save both time and money, which is good for the operator and for the manufacturer. I believe that this is one of the potential areas for long-term partnership between our airline and the Perm engine builders.
