OEM Obsolescence Should Not Ground Your Training Program: Reverse Engineering a Path Forward

Simtek helps commercial and defense training programs repair, reproduce, reverse engineer, and modernize unsupported simulator cockpit hardware.
Commercial aircraft fleets often remain in service for decades. Defense platforms may operate even longer, receiving upgrades, mission changes, avionics modifications, and life-extension programs long after the original cockpit hardware was designed.
Simulators must keep pace.
Eventually, many operators and simulator OEMs face the same challenge: a critical cockpit component fails, wears out, becomes obsolete, or is no longer supported by the original manufacturer.
A display is discontinued. A panel assembly is damaged. A control becomes unreliable. A lightplate becomes unreadable. A legacy instrument can no longer be repaired. The original supplier no longer has the tooling, documentation, components, or program support capacity to provide a replacement.
When that happens, the problem is not just hardware availability.
It is training availability.
The Aircraft May Keep Flying. The Simulator Still Has to Train.
Commercial and defense training programs cannot afford to lose simulator availability because of a single unsupported component.
Airlines depend on training devices for recurrent training, type ratings, upgrade training, and crew readiness. Defense organizations depend on simulators for mission preparation, procedural training, readiness, and continuation training.
In both environments, downtime creates pressure.
A delayed repair can affect instructor schedules, training throughput, device availability, customer commitments, and overall program cost. Surplus parts may provide a temporary answer, but they often create new uncertainty around condition, remaining life, documentation, and future support.
The better question is not simply, “Can we find another one?” It is, “What is the best way to restore capability and prevent this problem from happening again?”
Beyond Repair: A Practical Path Forward
Simtek supports commercial and defense simulator programs with solutions for legacy, worn, damaged, unsupported, and obsolete cockpit hardware.
Depending on the requirement, that may include repair, refurbishment, replacement manufacturing, modernization, or development of a new assembly that preserves the critical training and integration requirements of the existing device.
Whether the original component was produced by Simtek, another manufacturer, or an OEM that no longer supports the product, we can evaluate the requirement and help identify the most practical path forward.
Reverse Engineering When Documentation No Longer Exists
In many legacy simulator programs, the original drawings, CAD models, wiring data, bills of material, and technical documentation are no longer available. In other cases, the information exists but is incomplete, outdated, or tied to an OEM that no longer supports the assembly.
Simtek can help bridge that gap through reverse-engineering and reproduction capability.
Using available hardware, photographs, measurements, interface information, samples, and customer-provided documentation, Simtek can evaluate obsolete cockpit components and develop a practical path toward repair, replacement, or modernization.
That may include mechanical measurement and dimensional capture, panel and lightplate recreation, identification of obsolete components, electrical and interface assessment, recreation of control assemblies and display housings, and development of updated internal electronics while preserving required external form, fit, and function.
Reverse engineering is not simply copying an old part.
It is about understanding what the component must do within the simulator, identifying the critical training and interface requirements, and developing a supportable solution for the next phase of the program.
Direct Replacement Is Sometimes Right. Smarter Replacement Is Often Better.
There are situations where a direct, form-fit-function replacement is exactly what the program needs.
The mounting must remain unchanged. The connector must remain unchanged. The simulator software must continue operating without modification. The crew interface must remain familiar.
In those cases, a drop-in replacement may be the fastest and lowest-risk path back to service.
But direct duplication is not always the best long-term answer.
Legacy components may contain the same weaknesses that caused the problem in the first place: discontinued displays, obsolete electronics, aging lighting systems, difficult-to-source switches, fragile mechanical construction, or service-intensive internal assemblies.
Reproducing those limitations may solve today’s failure while creating tomorrow’s downtime.
Simtek works with customers to determine whether the right answer is to repair the existing unit, build a direct replacement, update internal electronics while preserving the external interface, replace obsolete displays with modern supportable technology, improve serviceability through modular construction, or develop a new assembly designed for long-term support.
The objective is not to redesign equipment unnecessarily.
The objective is to restore training capability with a solution that makes sense for the future of the device.
Built Around the Training Device, Not Just the Component
A replacement cockpit component must do more than physically fit in the opening.
It must work within the simulator’s complete environment, including mechanical mounting, panel geometry, backlighting, dimming, electrical power, discrete I/O, communications interfaces, host software, instructor controls, display characteristics, and maintenance access.
A replacement that looks correct but requires unexpected rewiring, software changes, or interface work can turn a simple repair into a much larger integration effort.
Simtek evaluates the full system impact before recommending a path forward. That approach helps customers avoid unnecessary surprises and ensures the replacement supports both the immediate need and the long-term training mission.
Keep Training Moving
When an original supplier can no longer support a simulator component, the answer should not automatically be extended downtime, surplus-part hunting, or a costly redesign of the entire cockpit.
There is usually a better path.
Whether the requirement involves commercial flight training, military readiness, legacy aircraft systems, modernized avionics, damaged cockpit hardware, or obsolete simulator components, Simtek can help evaluate the problem and develop a practical solution.
Aircraft programs evolve. Training requirements evolve. Simulator hardware should be able to evolve with them.
