| Type | Manufacturer | Model | Details |
|---|---|---|---|
| aircraft | Airbus | A310-324 | Airworthiness Directives; Airbus Model A310-324, A310-325, and A300 B4-622R Series Airplanes Equipped with Pratt & Whitney PW4000 Series Engines |
| engine | Pratt & Whitney | PW4000 Series | Airworthiness Directives; Airbus Model A310-324, A310-325, and A300 B4-622R Series Airplanes Equipped with Pratt & Whitney PW4000 Series Engines |
Unsafe Condition
Pratt & Whitney Model PW4000 series engines with certain early-production fan blades (Phase 0/1, FB2B or FB2T) installed on Airbus Model A310-324, A310-325, and A300 B4-622R series airplanes do not produce the amount of thrust indicated in the AFM. This thrust shortfall is due to erosion of the fan blade's leading edge, resulting in acceleration and climb performance less than that specified in the AFM.
