SUCCESS FOR S7 bookmark

S7 Technics enjoyed an increase in workload at its bases last year as the demand for aircraft maintenance in Russia and the CIS grew substantially. The company's technical specialists completed some 2.153 million standard hours in 2018, a 7.7% year-over-year improvement. The MRO performed 83 heavy maintenance checks in the period, 32 of which (almost 40%) accounted for base maintenance work and redeliveries, each project representing a significantly large amount of work. The growing demand for heavy checks and redeliveries at S7 Technics' bases reflects the entire region’s aviation market trend and reflects the recent peak of aircraft deliveries to Russia, the largest increase since 2008. Demand continues to show signs of growth, with two currently ongoing lease-return projects for major global lessors that are due to be completed in 2019.

During 2018, three S7 Technics’ bases, at Domodedovo (Moscow), Mineralnye Vody and Tolmachevo (Novosibirsk) airports, collectively provided 28,600 component repairs, a 27% improvement, whilst performing 97,600 standard hours of work, up by 34%.

At the same time, many new opportunities have emerged for students attending the S7 Technics Aviation Training Center, especially as the main achievement for the Training Center team has been mastering the CFM LEAP-1B-powered Boeing 737 MAX, a new aircraft type for Russian civil aviation. Given the expansion of activities, the ground footprint of the Training Center facilities increased last year, and the number of its specialists rose to 16. Also last year, the center, which has its own EASA Part 147 certificate, underwent regular scheduled inspections and audits carried out by the European aviation authorities.

Meanwhile, S7 Technics is continuing to introduce lean production tools into its work activities. With the involvement of external consultants, the company has established a Lean Basic course for initial training, in which more than half of S7 Technics’ workforce has completed 90 training sessions.

In order to reduce the time required for carrying out line maintenance, the Kit Car project was implemented at Domodedovo Airport, whereby several vehicles have been converted into mobile warehouses that then expeditiously deliver relevant spare parts, consumables, tools and equipment to aircraft parking places.

Among the main tasks expected of S7 Technics for the current year, is completion of the AMOS system implementation, expansion of cooperation with leasing companies and further improvement of customer services, the company says.


MTU Maintenance has launched its redefined services portfolio MTUPlus Intelligent Solutions. The portfolio has been conceived to fulfil the exact and specific needs of operators, who increasingly require tailor-made solutions across the lifecycle in order to control and optimise cost, as well as those of asset owners and lessors, for whom residual value and cost of ownership is key. The portfolio has been divided into four highly tailored solutions, PERFORMPlus, SAVEPlus, VALUEPlus, MOVEPlus, and a services cluster SERVICEPlus for single and ad-hoc requests.
PERFORMPlus has been designed for operators of newer current generation engines and focusses on generating more flight hours at lower cost with customised MRO, for instance through customised workscoping, alternative repairs, engine trend monitoring, spare engine support and onsite services to optimise on-wing times.

SAVEPlus is all about reduced cost with smart strategies for operators of mature engines. These are tailored to remaining flight periods and, where the invest is worth it, include customised workscoping, smart repairs and material salvation, or, wherever this is not the case, lease and exchange engines.

VALUEPlus is a solution for asset owners to maximise value with effective asset management at end-of-life. Exit strategies can range from generating additional income through green-time lease out to sale, exchange and trade all the way to maximising the material value of the asset through teardown and material management.

MOVEPlus is targeted at lessors and asset owners and focuses on risk mitigation and generating more revenue through portable MRO across the lifecycle. It enables faster remarketability of assets through easy transfers and predictable costs. Furthermore, it offers lessors the opportunity to be involved directly in maintenance decisions, in particular during transitions between lessees, managing and optimising maintenance reserves and choosing the timing of shop visits.

In addition to these fully integrated service solutions, MTU Maintenance provides a series of individual services under SERVICEPlus that round out and strengthen the core MTUPlus products. These range from component repairs and onsite and near-wing services to complementary services such as technical asset management, LRU management, spare engine or parts, and engine trend monitoring, amongst others. All of these services can be provided on an ad-hoc and singular basis, or combined as part of a customised solution.

TRENT 1000 TEN PROGRESS bookmark

Rolls-Royce says that, in response to earlier than anticipated High Pressure Turbine (HPT) blade deterioration identified in a small population of Trent 1000 TEN engines, it has been working closely with regulatory authorities to establish a plan for inspecting the remaining fleet. This accelerated inspection regime has now been agreed and will be formally communicated to customers. As part of this process, an Airworthiness Directive will be issued by EASA in addition to a Rolls-Royce Service Bulletin.

Following sampling of a population of Trent 1000 TEN engines that have experienced a higher frequency of flights at the upper end of their operating range, a small number of these engines have needed to have their HPT blades replaced earlier than scheduled. This new accelerated inspection regime is designed to confirm the health of the Trent 1000 TEN fleet over the next few months.

Since the entry into service of the Trent 1000 TEN, Rolls-Royce has communicated to airlines that the HPT blades in these engines would have a reduced life. As a result, engineers have already been developing, and are currently testing, an enhanced version of this blade. The company expects to start incorporating enhanced blades into the Trent 1000 TEN fleet in early 2020.
