The GE90 Growth, which includes the GE90-110B and GE90-115B versions, is one of the largest and most powerful engines in the world. Developed exclusively for the current models of the Boeing 777 family—the 777-200LR (Long Range), the 777-300ER (Extended Range), and the 777-200F (Freighter)—these engines are characterized by a thrust of up to 115,000 pounds.
MTU Maintenance Hannover plays a key role in the maintenance of these engines. As one of the world’s first maintenance companies with a license for the repair and overhaul of the GE90 Growth, MTU Maintenance Hannover has been offering a comprehensive range of services for over a decade.
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.
