Airworthiness Directive · Amendment 39-17632 · Fuel
ATR-GIE Avions de Transport Régional Airplanes
This AD applies to ATR—GIE Avions de Transport Régional Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes, certificated in any category, except airplanes that have received ATR Modification 5948 in production.
We are adopting 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 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 AD requires installing a fuel quantity indicator (FQI) equipped with a locking adaptor on the electrical connector. We are issuing this AD to prevent an engine flame-out, which could result in reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD: Install a fuel quantity indicator (FQI) equipped with a locking adaptor on the electrical connector, in accordance with the Accomplishment Instructions of Avions de Transport Régional Service Bulletin ATR72-28-1026, dated February 26, 2013.
(1) For airplanes on which a fuel secondary low level detection system is not installed: Within 24 months after the effective date of this AD.
(2) For airplanes on which a fuel secondary low level detection system is installed: Within 36 months after the effective date of this AD.
Note 1 to paragraph (g) of this AD: The fuel secondary low level detection system may have been installed through the embodiment of ATR Modification 04686 in production, or as applicable, through ATR Service Bulletins ATR72-28-1013 or ATR72-28-1022 in service.
