351-4010-21GSE is a specialized aerospace engine high-pressure compressor (HPC) blade maintenance GSE (Ground Support Equipment), compliant with AS9100D quality standards and aviation maintenance specifications, designed for large commercial turbofan engines. It is used to safely remove and install HPC rotor blades during on-ground maintenance, ensuring the blades are handled without damage, and their position and angle are accurately restored, which is critical for maintaining HPC compression efficiency, avoiding blade damage that may cause engine vibration or performance decline.

Made from high-strength, lightweight aerospace aluminum alloy with a precision positioning structure, it operates stably in -20°C to 120°C ground environments. Weighing 1.2kg with an anti-slip operating part, it allows for fast and accurate operation during HPC MRO. It is an essential tool for engine on-ground maintenance.
