PWA111052 is a high-performance turbine blade retainer pin, engineered to AS9100D aerospace quality standards and FAA AC 43.13-1B regulations, specifically designed for Pratt & Whitney PW4000-94 turbofan engines powering Boeing 747-400, 767 and Airbus A300, A310 aircraft.

Crafted from heat-treated Inconel 718 superalloy with a plasma-sprayed ceramic coating, it withstands operating temperatures up to 1,200°C and centrifugal loads of 28,000 lbf, critical for securing first-stage turbine blades in the engine core. Measuring 38.1 mm in length with a precision-machined 6.35 mm diameter, it features a knurled surface for anti-slip retention in the turbine disk. This component ensures blade stability during takeoff, cruise and landing cycles, making it an essential part for MRO teams to maintain engine integrity and prevent catastrophic failures.
