856A1357G05 is a specialized sensor tester designed exclusively for the CFM56-3 engine, a core powerplant of the Boeing 737 Classic series, compliant with aerospace maintenance standards like AS9100 and FAA 8130-3. It serves as a critical diagnostic tool for MRO technicians, enabling precise testing of the engine’s sensor array—including T12 fan inlet temperature sensors, N1 speed sensors, and oil quantity sensors—by simulating real-time operational signals to verify sensor accuracy and functionality.

Crafted from rugged aerospace-grade aluminum with a waterproof IP67-rated casing, it withstands harsh engine bay conditions (-40°C to 85°C) and vibration up to 15g. Its plug-and-play design connects directly to the CFM56-3’s test electrical port, delivering instant feedback on sensor performance to streamline fault diagnosis, reduce unplanned engine downtime, and ensure compliance with aviation safety regulations for reliable aircraft operation.
