AS9100D manufacturing and FAA Part 145 repair support for OEM line-fit, retrofit, and fleet modernization programs.
Overview
Polytronix manufactures AS9100D-certified cockpit displays, panel assemblies, standby instruments, cabin management interfaces, electro-mechanical cockpit LRUs, retrofit STC interconnect harnesses, cabin management and lighting control PCBAs, and complete box-build avionics units for business jets, turboprops, and general aviation aircraft. Designed to enhance flight safety, efficiency, and passenger comfort, our business and general aviation solutions support OEM line-fit programs, Supplemental Type Certificate (STC) retrofit upgrades, panel refresh programs, and operator-driven flight deck modernization.
We replace legacy cathode-ray-tube (CRT) displays with high-resolution liquid crystal displays (LCDs), refresh aging analog instrumentation with digital flight displays, and integrate connected avionics suites, situational awareness, precision navigation, datalinks, ADS-B, traffic and weather radar, advanced sensors, and enhanced vision into new aircraft and legacy airframes.
We deliver sunlight-readable ruggedized LCDs, optically bonded cockpit displays, backlit instrument panels and bezels per MIL-DTL-7788 and QPL-7788 form factor, multi-function display modules, standby instrument displays, electronic standby indicator (ESI) assemblies, cabin management system (CMS) interfaces, and complete electro-mechanical panel assemblies. Display modules are environmentally aligned to MIL-DTL-7788 profiles and DO-160 test procedures to support the temperature, humidity, vibration, and altitude cycles characteristic of business jet and general aviation operations.
Internal wiring is built under IPC/WHMA-A-620 Class 2/3 with MIL-DTL-38999 and rectangular ARINC connectors, coaxial and RF assemblies for navigation, communications, and ADS-B, supporting both new-installation programs and STC retrofit kits. Polytronix delivers build-to-spec, design-collaborative, and reverse-engineered retrofit solutions under serialized configuration control with full FAA documentation, AS9100D quality, and ITAR-controlled production where applicable.
