“It is a signal that market demand for spare parts is so strong,” Mingyang Chen says.

Disassembly, then, does not necessarily mark the point at which everything aboard an aircraft has reached the end of its useful life. Done at the right moment, disassembly can release valuable components while they still have significant utility for other operators. Timing is therefore important, not only for the value of the aircraft being dismantled, but also for parts availability across the wider aftermarket.

Chengdu closes the loop

Satair Chengdu forms part of the Airbus Chengdu Life Cycle Services Centre, a roughly 600,000-square-metre facility connected directly to the runway at Chengdu Shuangliu International Airport.

Mingyang Chen describes Satair Chengdu as both “the starting point” and “the end point” of the USM value chain.

Satair acquires aircraft and sends them for dismantling at the centre. A teardown can involve around 1,500 individual part numbers. Once removed, components are transferred to Satair Chengdu’s 4,200-square-metre USM warehouse as “as-removed” material.

They are then routed to appropriate repair organisations. Once repaired and certified, they return as serviceable USM that Satair can make available to customers in China and globally.

An aircraft arriving in Chengdu at the end of its operational lifecycle can therefore leave, piece by piece, as material capable of supporting many other aircraft.

For Mingyang Chen, this is what makes facilities such as Chengdu increasingly relevant to the supply chain. Valuable components do not have to reach the end of their economic lives at the same time as the aircraft they came from. They can be recovered, returned to service and redistributed to where they are needed.

From end-of-life to another useful life

The work in Chengdu reflects a broader change in how aircraft retirement can be viewed. Aircraft owners and asset managers increasingly have to consider where the remaining value of that aircraft can be put to best use, and sometimes maintenance economics, asset values and demand for specific components can make disassembly the more valuable option.

For Mingyang Chen and his team at the Airbus Chengdu Life Cycle Services Centre, the next step is turning that decision into usable supply: recovering components, returning them to serviceable condition, and putting them back into the aftermarket.

In that sense, disassembly is not simply the end of an aircraft’s useful life. Timed correctly, it can be the point at which one aircraft starts helping to keep many others flying.
