Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This proposed AD was prompted by reports of fuel quantity indication malfunctions caused by fuel probe failure. This proposed AD would require identifying the part number and serial number of the fuel probes and replacing if necessary. We are proposing this AD to prevent fuel probe failure, which could lead to undetected fuel starvation and consequent dual engine in-flight flame-out.
