Airworthiness Directives; Airbus Airplanes

We are adopting 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) Model CF6-80C2 series engines. This AD was prompted by reports of two single-engine flameout events during inclement weather. This AD requires installing a shunt of the rotary selector (introducing an auto-relight function); and, for certain airplanes, a wiring modification to a certain circuit breaker panel. We are issuing this AD to prevent a long engine restart sequence after a non-selection of continuous relight by the crew and a flameout event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.
