We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-601, B4-603, and B4-605R airplanes, Model A300 F4-605R airplanes, Model A300 C4-605R Variant F airplanes, and Model A310-204 and -304 airplanes, powered by General Electric (GE) CF6-80C2 series engines. This proposed AD was prompted by reports of two single-engine flame-out events during inclement weather. This proposed AD would require installing a shunt of the rotary selector (introducing an auto-relight function). We are proposing this AD to prevent a long engine restart sequence after a non-selection of continuous re-light by the crew and a flame-out event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.
