Airworthiness Directive · Amendment 39-15111 · Airbus Model A330 and A340 Airplanes
Airbus Model A330 and A340 Airplanes
This AD applies to Airbus Model A330 and A340 airplanes; certificated in any category; on which one of the Airbus Electronic Instrument System 2 (EIS2) software versions listed in Table 1 of this AD is installed; excluding those airplanes on which Airbus Modification 53063 has been done in production.
| EIS2 software version | Installed by this Airbus Modification in production | Or installed by one of these Airbus Service Bulletins in service |

| L5 | 51974 | A330-31-3056, A330-31-3069, A340-31-4087, or A340-31-5012. |
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330-200, A330-300, A340- 200, and A340-300 series airplanes; and Model A340-541 and -642 airplanes. That AD currently 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 new AD requires installing new software, which would end the actions required by the existing AD. This new AD also adds additional airplanes that may be placed on the U.S. Register in the future. 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.
For Model A330-201, -202, -203, -223, -243, -301, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes: Within 2 days after September 12, 2005 (the effective date of AD 2005-17-18), 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.
For airplanes other than those identified in paragraph (f) of this AD: 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, do the reset specified in paragraph (f) of this AD and repeat thereafter at intervals not to exceed 4 days, until the installation required by paragraph (h) of this AD has been done.
(h) For all airplanes: Within 7 months after the effective date of this AD, install EIS2 software standard L6-1 in accordance with the applicable service bulletin identified in Table 2 of this AD. Accomplishing the installation ends the actions required by paragraphs (f) and (g) of this AD.
