Mehmet Cetin, product owner, mechanical systems at Fokker Services, explains the main factors to consider when repairing these systems. "In general, pneumatic components are susceptible to dirt and corrosion, which can lead to bleed air components getting stuck in a certain position," he says. "Typical faults that we see for hydraulic components are leakages, which result in pressure losses within the system, or the contamination of fluid, which can cause wear and tear within (sub)components."

"Owing to the Covid-19 pandemic, aircraft around the world were placed into storage. While in storage, the environmental conditions impacted the pneumatic bleed air system of some of these aircraft. Operators are now faced with valves that are stuck or that have seized up due to corrosion."

We have recently invested in technology that aims to prevent the replacement of expensive subparts.

"For hydraulic components, proper sealing is essential to prevent pressure loses within the system. When seals are pressurized with hydraulic fluid, material tends to expand. However, due to inactivity the seals could be shrinking and may not be properly fitted at the surface. This could lead to unexpected early failures of hydraulic components with leakages.

If faults are detected, operators can send their accessories to one of the Fokker Services in-house repair facilities in the Netherlands or USA."
