Superseded. A later AD replaced this one: AD 2007-13-07. Comply with the one in force.
This AD applies to Airbus Model A330-201, -202, -203, -223, -243, -301, -321, -322, -323, -341, -342, and -343 airplanes; and A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes; certificated in any category; on which one of the Airbus Electronic Instrument System (EIS) 2 software versions listed in Table 1 of this AD is installed.
| EIS 2 software version | Installed by this Airbus modification in production | Or installed by one of these Airbus service bulletins in service |
|---|---|---|
| L4-1 | 51153 | A330-31-3056, A330-31-3057, or A340-31-5001. |
| L5 | 51974 | A330-31-3056, A330-31-3069, A330-31-4087, or A340-31-5012. |
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and Model A340-541 and -642 airplanes. This AD requires repetitively resetting the display units (DUs) for the electronic instrument system (EIS) either by switching them off and back on again or by performing a complete electrical shutdown of the airplane. This AD results from an incident in which all of the DUs for the EIS went blank simultaneously during flight. We are issuing this AD to prevent automatic reset of the DUs for the EIS during flight and consequent loss of data from the DUs, which could reduce the ability of the flightcrew to control the airplane during adverse flight conditions.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 2 days after the effective date of this AD, or within 4 days after the last reset of the DUs for the EIS or complete electrical shutdown of the airplane, whichever is first: Reset the DUs for the EIS by doing the actions in either paragraph (f)(1) or (f)(2) of this AD. Thereafter, do the actions in paragraph (f)(1) or (f)(2) of this AD at intervals not to exceed 4 days.
(1) Switch off each DU for the EIS, wait 5 seconds or longer, and switch the DU back on again, in accordance with Airbus All Operator Telex (AOT) A330-31A3092 (for Model A330-201, -202, -203, -223, -243, -301, -321, -322, -323, -341, -342, and -343 airplanes), A340-31A4102 (for A340-211, -212, -213, -311, -312, and -313 airplanes), or A340-31A5023 (for Model A340-541 and -642 airplanes), all dated August 1, 2005, as applicable. This action may be performed by the flight deck crew or by certificated maintenance personnel.
(2) Perform a complete electrical shutdown of the airplane.
