This paper provides an insight into how the introduction and implementation of the blending borescope used to perform on-wing blending of compressor blades on Pratt & Whitney (P&W) Engines has resulted in significant savings. It describes the following: Commercial statistics and savings; Military statistics and potential savings; P&W maintenance team; What is on-wing blending; The capabilities of on-wing blending; The contents of a typical blending borescope inspection kit; Test results; Measurement of Foreign Objects Damage (FOD); Installation of the equipment; How to blend FOD; How to measure the repair and observe how the equipment provides precise results; How to polish the repair.Typical commercial cost savings for blending assembled compressors are in the order of $360,000.00 per event, compared with engine teardown cost. P&W provides 24 hour, hassle-free blending borescope on-wing maintenance service to commercial customers worldwide, and proposes to provide the same service to P&W's military customers worldwide. This service combines the expertise and resources to maintain safety and reliability in the skies while minimizing engine down time and maintenance costs.
