856A1520G02 is a precision aviation maintenance tool, specifically a calibrated feeler gauge set engineered for measuring tight clearances in aircraft engine components (e.g., valve seats, piston rings, bearing assemblies) of commercial/regional turbofan engines. Designed for MRO and assembly workflows, it delivers accurate gap measurements to ensure optimal component fit, prevent friction-induced wear, and maintain engine operational efficiency.

Crafted from aerospace-grade high-carbon steel with a corrosion-resistant chrome plating, it withstands extreme temperatures (-40℃ to 180℃) and harsh maintenance environments while retaining dimensional stability. Compliant with OEM specifications and SAE AS9100 standards, the set includes multiple precision blades with laser-etched thickness markings for quick identification.

Compact and portable with a durable storage case, it enhances workflow efficiency in confined engine compartments, reduces inspection time, and ensures compliance with airworthiness regulations. This tool is indispensable for upholding component integrity, extending engine service life, and safeguarding aircraft operational safety.
