Overview

A hydraulic component test stand and servocylinder test station operator and maintainer checks, tests, troubleshoots, and repairs hydraulic and pneumatic components. The technician performs this work using the A/F-27T-12 hydraulic component test stand and servocylinder test station.

Core Skills

  • Hydraulic and pneumatic component fault isolation
  • Hydraulic and pneumatic component repair

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Aircraft Mechanics and Service Technicians

Hydraulic and pneumatic component testing, troubleshooting, and repair transfer directly to the hydraulic-component portion of aircraft maintenance.

How to prepare: Gather military maintenance records for FAA review of experience toward an Airframe rating before choosing additional schooling. For FAA certification, applicants must be at least 18, meet English-language requirements, pass written, oral, and practical tests, and have 18 months of appropriate experience for one rating or 30 months concurrently for both, or complete an accepted training route; certification is not required for every airline mechanic job, though carriers often require it.

What the civilian work involves
  • Read and interpret maintenance manuals, service bulletins, and other specifications to determine the feasibility and method of repairing or replacing malfunctioning or damaged components.
  • Examine and inspect aircraft components, including landing gear, hydraulic systems, and deicers to locate cracks, breaks, leaks, or other problems.

Inspectors, Testers, Sorters, Samplers, and Weighers

Operational checks and test-station testing of hydraulic and pneumatic components provide a foundation for component inspection and functional-test work.

How to prepare: Practice recording component test results against acceptance criteria for hydraulic or pneumatic manufacturing inspection roles.

What the civilian work involves
  • Inspect, test, or measure materials, products, installations, or work for conformance to specifications.
