AD NUMBER: 2004-20-06
MANUFACTURER: Airbus SUBJECT: Airworthiness Directive 2004-20-06 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain Airbus Model A330 and A340series
airplanes. This AD requires revising the airplane flight manual to
provide procedures forthe flightcrew to follow in the event of the
loss of all liquid crystal display (LCD) units on airplanes
equipped with the EIS2 standard of electronic instrument system.
This AD is prompted by reports of the brief but total loss of all
LCD units during cruise on airplanes equipped with the EIS2standard
of electronic instrument system. We are issuing this AD to provide
procedures to theflightcrew to restore operation of these LCD units
and prevent prolonged loss of critical flight information to the
flightcrew and the consequent reduced ability of the flightcrew to
control theairplane during adverse flight conditions.
