Expert, efficient hydraulic system fluid analysis can prevent costly problems

A potential hydraulic system contamination issue arose with a New Zealand Defence Force (NZDF) B757. An NZDF engineering officer believed contamination had been avoided but needed final assurance on the integrity of the hydraulic system. One of two Boeing 757s used by the NZDF for troop and equipment deployment and evacuations needed fluid analysis to return to service. Time was of the essence. The alternative? A full-system flush, which would be very time consuming and expensive.

“I was impressed with the speed and professionalism of the Eastman team in dealing with our particular situation. Including the sample testing in the Skydrol product offering is nice, but in this case, the turnaround time was what really mattered. They realized we had an urgent request and handled it accordingly.” — AJ Sasidharan NZDF flight lieutenant

Eastman Turbo Oil 2197 exhibits best-in-class performance in reducing critical vent tube coking.

Currently, due to the high performance capable (HPC) oil being used, Dare MedFlight is required to clean the engine vent lines on the two engines of its BK-117 helicopter every 15–20 service hours. This can be a tedious and time-consuming process, and as a rapid medical transportation provider, time is of the essence for Dare MedFlight.

“After performing this comparison and seeing the difference between the two products for myself, I requested that our new helicopter be delivered with Eastman Turbo Oil 2197 already in both engines.” —Howard Wilson, director of maintenance, Dare MedFlight

The challenge

Demonstrating the significance and benefits of oil performance in reducing engine coking in CFM56-5B engines

The solution

Eastman Turbo Oil 2197™ is proven to reduce or completely eliminate coking in bearing compartments and especially the #5 bearing supply tube on all models of the CFM56 engine, thereby improving maintenance efficiencies and decreasing related costs.

Eastman Aviation Solutions participated in an oil systems review of a Juneyao Airlines CFM56-5B in which Eastman Turbo Oil 2197 has been used exclusively since the engine’s entry into service in December 2006. The engine accumulated 30,312 hours and 15,080 cycles since new and was removed for scheduled performance restoration and core section life-limited parts (LLP) replacement.

Considering the extraordinarily high time on the engine and its 2:1 hour/cycle ratio usage, the engine oil system was exceptionally clean and free of oil-derived deposits.
