## Abstract

This document makes a correction to Airworthiness Directive (AD) 2004-14-02. That AD applies to Rolls-Royce Corporation (formerly Allison Engine Company, Allison Gas Turbine Division, and Detroit Diesel Allison) models 250-C28, -C28B, and -C28C turboshaft engines with certain serial number (SN) third-stage turbine wheels, part number (P/N) 6899383.

This document corrects these two sentences. In all other respects, the original document remains the same.
