856A4639G10 is a specialized fan blade tip clearance checking tool for aircraft engine maintenance, complying with AS9100 aerospace standards and aviation precision measurement specifications. It accurately measures the tip clearance between aircraft engine fan blades and frames, a key parameter to avoid blade - casing friction and ensure engine efficiency.

Made of wear-resistant alloy with anti-corrosion treatment, it resists engine bay temperature fluctuations (-30°C to 80°C) and oil contamination. Its compact, calibrated design allows easy access to narrow engine spaces and ensures measurement accuracy.

Critical for MRO workflows, it helps technicians timely detect abnormal clearances, supporting engine reliability and avoiding catastrophic flight risks caused by blade damage.
