4th CMS hydraulics Airmen design, use apparatus to test stabilator actuators

The F-15E Strike Eagle depends on many parts to maintain operational status. One mission critical part is the stabilator actuator. The hydraulic actuator, which moves the stabilator of an F-15E, defects collectively for pitch control and differentially to add roll control power to the jet ailerons.


Airmen from the 4th CMS hydraulics shop designed an apparatus that would enable them to test stabilator actuators.


“The new apparatus tests the electrical output of the physical dimensions of where the actuator is at in the aircraft,” said Staff Sgt. Steven Hall, 4 CMS centralized repair facility expeditor. “With this new process, we are pushing out stabilator actuators in about eight hours instead of 72 days, which is what depot is turning.”


Fannin added, we have produced 12 serviceable assets out or the 14 or 15 that we have tested. Four of these have already successfully flown on F-15E’s assigned to SJAFB.


Having the test apparatus on base results in quicker turnaround times for stabilator actuators, which in turn means more training for air crew members, more F-15Es in the air and more aircraft ready for wherever our mission takes us.


Right now, SJAFB is the only base apart from the depot facility at Hill AFB, Utah that can overhaul the hydraulics side of stabilator actuators. Having more of the test apparatuses made will give SJAFB the ability to increase our readiness and lethality.


“In the future, we will have more of these made and test apparatus will be deployable,” said Hall. “If our Airmen get a stabilator down range, it can be quickly returned to working conditions while in a deployed location instead of being sent back to our home station. Having this test apparatus allows us to maintain our aircraft and provide combat air power for America.”
