## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires a one- time inspection to determine the part number or markings of the fuel quality indicator (FQI) and replacement of any FQI having an incorrect part number. This AD results from a report that an FQI having an incorrect part number was installed on a Model ATR72 airplane. We are issuing this AD to ensure that a correct FQI is installed. An incorrect FQI could result in fuel starvation to the engine and consequent engine shutdown during flight.
