When servicing an air/oil shock strut with MIL-5606, what is the correct procedure?

When servicing an air/oil shock strut with MIL-5606, the correct procedure involves expanding the strut and adding fluid. This method ensures that the internal components of the strut are positioned correctly, allowing the fluid to circulate effectively and fill the internal chamber without trapping air. By expanding the strut, you allow the fluid to fill the cylinder to the appropriate level while ensuring that any air can escape, which is crucial for maintaining the proper function of the shock strut.

Using this approach helps to prevent the introduction of air into the system, which can lead to a loss of shock absorption capability and may compromise the overall performance of the landing gear. It's important to follow this procedure closely to maintain the integrity and safety of the aircraft's landing gear system.
