Airworthiness Directives; Airbus Model A300 B2 and A300 B4; Model A300 B4-600, B4-600R, C4-605R Variant F, and F4-600R (Collectively Called A300-600); and Model A310 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B2 and A300 B4; Model A300 B4- 600, B4-600R, C4-605R Variant F, and F4-600R (collectively called A300- 600); and Model A310 series airplanes. This AD requires an inspection to determine the part number of certain passenger/crew escape slides; and related investigative action and corrective action, if necessary. This action is necessary to prevent the failure of an escape slide to deploy during emergency evacuation, which could impede an evacuation and result in injury to flightcrew and passengers. This action is intended to address the identified unsafe condition.
