Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

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.
How often should industrial gas turbines undergo performance testing?

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.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

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.
What temperature ranges do your military-grade ICs support?

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.
Are PMA parts interchangeable with OEM components?

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.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

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.
