PWA211799 is a critical aerospace component—an engine high-pressure turbine (HPT) blade retainer clip, engineered to Pratt & Whitney’s rigorous aviation standards and AS9100D quality protocols, compliant with FAA/EASA airworthiness regulations. Optimized for PW1100G-JM geared turbofan engines in Airbus A320neo family, it secures HPT blades to the rotor disk, maintaining precise circumferential spacing and axial positioning essential for aerodynamic efficiency and engine integrity during high-temperature, high-load operations.

Fabricated from nickel-based superalloy (Inconel 718) with vacuum heat treatment for enhanced creep resistance, it features precision-machined dovetail grooves (±0.005mm tolerance) and anti - galling coating. Lightweight (18g) and compact, it ensures reliable blade retention, minimizes vibration - induced wear, and upholds engine performance stability and post - overhaul airworthiness for commercial fleets.
