Sukhoi Superjet underused due to lack of spare parts
In 2016, Sukhoi SuperJet 100 (SSJ100) aircraft operated in Russia were flying for approximately 3-3.7 hours a day, according to Russian news portal Vedomosti. Across the Atlantic, Mexican Interjet – the largest foreign operator of the model with 22 SSJ100s in its fleet – had more efficient operations, with the average being around 5-7 hours a day. Worldwide, the average time spent in air by SSJ100 aircraft (totaling at 73 units) was four hours.
The airliner is operated by Interjet, Citijet and Royal Thai Air Forces.
In commercial aviation, nine hours of flight time per day is considered good and this number can be higher when the aircraft is operated by efficient low-cost carriers.
The reasons for the low numbers in case of the Sukhoi SuperJet 100 are expensive spare parts and their scarce availability, according to a Russian aviation source quoted by Vedomosti. This is due to the fact that this type of aircraft is produced in small quantities, and third-party suppliers are not interested in producing components. The United Aircraft Corporation (UAC) is responsible for spare part production but it has the state defense order as a priority. Another reason for the problems with the aircraft is the extensive document flow accompanying the exchange of spare parts for the aircraft.
In addition, there is the Russian Federal Air Transport Agency's requirement to provide a passport for each component indicating where, by whom and for how long the component was used. Such practice is unheard of in many parts of the world.
In January 2017, every fifth SSJ100 was grounded. Then FATA had suspended the operations of all aircraft, which had defective tail stabilizers.
