“Total Care has the overall benefit of risk transfer for the operator, as it covers unplanned maintenance operations,” adds Seymour. “The use of Total Care is in line with the interests and objectives of the OEM and the operator, which are to maximize thawing time and minimize spare parts on the ground. In the meantime, the operator uses access to the best available materials and the availability of SV. “FHAs were originally designed to attract airlines, as they were once the main buyers of new aircraft,” says Razzhivina. “Airlines assess the safety of costs for the duration of the contract that FHAs offer.” While it may seem obvious, the number of engines in an aircraft will also affect longevity in the market, fleet-wide and not on an individual basis. If operators enter into maintenance contracts with OEMs, the payment will be less attractive for four engines than the payment for two. The comprehensive care caused some problems for the owners. Operators have encountered problems with the age of the engines and need more flexible ways to optimize maintenance management. “Maintenance costs are primarily determined by materials that accounted for 80 percent of SV`s costs,” says Rubin. “The cost of engine maintenance is very high during the second decade of an engine`s lifespan, with the need for increasing replacement or repair, as parts wear out and average distance intervals between VSS are shortened.” Owners also need to determine if the TotalCare contract is compatible with the term of the lease agreement,” Ray explains. “What will happen if the lease is renewed? Will the operator choose to extend their registration with TotalCare? If the operator`s lease ends, what is the amount of the buyback tax to keep the engines on TotalCare? Further discussions need to be held in order to avoid any problems during an aircraft transfer, beyond the question of whether the lessor can access the maintenance reserves. An operator of a new type of engine, the primary lessee, has a different perspective and priority than a secondary lessee or the owner of an aging engine. Let`s take the example of a new EIS engine. As noted (see Acquisition of Next Generation Engine Maintenance Capacity, Aircraft Commerce, February/March 2015, page 34), they may be subject to early operating problems, performance improvement, extra-budgetary MSM and hospital visits. .
