Examples of Technical Requirements AeroNex Can Evaluate
The following scenarios illustrate aircraft hydraulic system and component requirements that may align with AeroNex’s engineering capabilities. Each example highlights the types of technical factors that may require evaluation, the support AeroNex may provide, and the form an engineering deliverable could take.
Hydraulic Actuator Exhibiting Inconsistent Performance
A hydraulic actuator exhibits inconsistent extension or retraction behavior under certain operating conditions.
The reported condition may involve slow movement, irregular response, internal leakage, reduced force capability, incomplete travel, or performance that changes under load.

- Internal leakage or bypass
- Seal condition
- Friction or binding
- Mechanical alignment
- Load conditions
- Contamination
- Component wear
- Temperature effects
- Test configuration
- Installation conditions
- Interaction with connected components
- Review of reported symptoms
- Review of available test results
- Functional actuator analysis
- Evaluation of potential failure modes
- Identification of information gaps
- Development of technical questions
- Troubleshooting recommendations
- Repair-versus-replacement considerations
A technical assessment summarizing the available evidence, potential contributing factors, information gaps, and recommended next steps.
Hydraulic Pressure Loss or Instability Under Operational Load
A hydraulic system performs normally under certain conditions but experiences pressure loss, fluctuation, delayed response, or instability as system demand increases.
The condition may occur intermittently or only during a particular operating sequence.
- Pump output
- Pressure regulation
- Priority-valve operation
- Flow demand
- Internal leakage

- Development of a structured troubleshooting plan
- Identification of useful follow-up tests
A troubleshooting memorandum identifying potential contributing factors, evaluation priorities, information gaps, and recommended next actions.
Selector Valve Exhibiting Delayed, Intermittent or Incorrect Response
A selector valve or related control assembly does not consistently route hydraulic pressure or flow as expected.
The condition may involve delayed response, internal leakage, sticking, incomplete shifting, pressure loss, or unexpected downstream component behavior.
- Valve configuration
- Spool or internal-element movement
- Contamination
- Wear
- Internal leakage
- Pressure differential
- Return-flow restriction
- Actuation method
- System sequencing
- Installation conditions
- Test procedure

- Evaluation of reported symptoms
- Failure-mode analysis
- Test-data review
- Component interaction review
- Troubleshooting recommendations
- Identification of additional inspection or test needs
A technical evaluation outlining potential contributing factors, required information, and recommended troubleshooting steps.
Recurring Component Removals Without a Confirmed Cause
An operator, MRO organization, or repair facility experiences repeated removals of the same hydraulic component type while shop findings or bench testing do not consistently reproduce the reported aircraft condition.
This can create uncertainty as to whether the issue originates within the removed component, the surrounding system, operating conditions, or the test environment.
- Aircraft-level system behavior
- Installation conditions
- Electrical or control inputs
- Pressure and flow availability
- Interface components
- Maintenance practices
- Environmental conditions
- Bench-test limitations
- Removal criteria
- No-fault-found history
- Review of removal and maintenance history
- Comparison of aircraft symptoms and shop findings
- System and component interaction review
- Identification of recurring patterns
- Evaluation of existing test coverage
- Development of additional troubleshooting questions
- Recommendations for improved data collection
- Independent technical review
A structured technical summary identifying gaps between the reported condition and existing inspection or test findings, with recommended priorities for further evaluation.
Obsolete Hydraulic Component with Incomplete Technical Data
An organization must continue supporting a hydraulic component for which original drawings, specifications, repair data, approved sources, or other design information are incomplete or unavailable.
The challenge may involve understanding the component’s function, determining important characteristics, evaluating available repair information, or identifying a practical path for continued support.
- Component function
- System interfaces
- Critical dimensions
- Materials
- Pressure requirements
- Flow characteristics
- Sealing
- Operating environment
- Existing repair history
- Replacement options
- Configuration differences
- Available documentation
- Functional component analysis
- Documentation-gap assessment
- Review of available drawings and records
- Identification of critical technical characteristics
- Reverse-engineering support
- Repair-versus-replacement evaluation
- Development of technical questions
- Test-requirement support
A component assessment summarizing known information, functional requirements, major data gaps, technical considerations, and recommended next steps.
Repair, Replacement or Continued-Support Evaluation
An organization must determine the most appropriate path for an aging hydraulic component that may require repair, replacement, substitution, redesign, or continued support.
The decision may be influenced by component condition, reliability, availability, documentation, compatibility, supply-chain constraints, testing requirements, and operational impact.
- Component condition
- Failure history
- Repair effectiveness
- Replacement availability
- System compatibility
- Qualification requirements
- Documentation quality
- Supply-chain constraints
- Operating risk
- Test capability
- Long-term supportability
- Review of available technical options
- Comparison of key considerations
- Evaluation of component function
- Review of repair history
- Identification of information gaps
- Technical input for decision-making
- Development of evaluation criteria
- Documentation of engineering considerations
A technical options assessment summarizing the available alternatives, major considerations, information gaps, and recommended follow-up actions.
