Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A340-600 series airplanes. This AD requires a detailed inspection for abnormalities of the ball lock retainer on the off-wing ramp slides; for closure of the soft cover; for full engagement of the slide release pin; for broken, missing, and improper placement of the safety tie thread on the slide release pin; and for proper functioning of the vent valve; and replacement of the off-wing ramp slides if necessary. This AD was prompted by reports of in-flight loss of the blow-out panel and the slide unit from a right-hand off-wing ramp- slide. We are issuing this AD to detect and correct abnormalities of the ball lock retainer, if the soft cover is open, if the slide pin release is not engaged or the safety tie thread is missing, broken, or improperly placed and the vent valve is not functioning properly, which could result in in-flight loss of the off-wing ramp slide.
