Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes; and all Model A340- 200, -300, -500, and -600 series airplanes. This AD was prompted by reports that the potable water service panel access door was lost during flight. This AD requires modifying affected potable water service panel access doors. We are issuing this AD to prevent failure of the latching mechanism of the potable water service panel access door, which could result in the loss of the potable water service panel access door during flight, and resultant damage to the airplane (e.g., damage to the trimmable horizontal stabilizer) that could cause loss of control of the airplane.
