Summary
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72-101, - 201, -102, -202, -211, -212, and -212A airplanes. This proposed AD was prompted by reports of airplane incidents and accidents that have occurred because of low-level fuel tank situations and fuel starvation that resulted in engine flameouts. This proposed AD would require installing a fuel quantity indicator (FQI) equipped with a locking adaptor on the electrical connector. We are proposing this AD to prevent an engine flame-out, which could result in reduced controllability of the airplane.
