The T53 family of engines has logged more than 50 years of service and more than 62 million flight hours on some of the world’s most iconic helicopters including the Bell UH-1H Huey, Huey II and AH-1H Cobra, as well as the commercially certified Kaman K-Max, Bell 204 and 205B helicopters.
Originally developed by our legacy company Lycoming, the T53 design team was headed by Anselm Franz, designer of the famous WWII Junkers Jumo 004, the world’s first turbojet engine.Today, the legacy of the T53 remains intact.A properly maintained, 30-year-old T53 still meets today’s rigorous reliability standards.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
