Synopsis:
|
On January 25, 2008, about 0945, an Airbus A320, N462UA, operated by United Airlines as flight 731, returned to Newark Liberty International Airport (EWR), Newark, New Jersey, shortly after departure from runway 22R because three of the six electronic displays1 providing information to the flight crew went blank and several aircraft systems became inoperative. The flight crew landed the airplane without further incident, and no injuries were reported for anyone on board the flight. Visual meteorological conditions (VMC) prevailed at the time of the incident for the 14 Code of Federal Regulations Part 121 scheduled domestic flight, which was operating on an instrument flight rules flight plan.

Recommendation:
|
TO THE FEDERAL AVIATION ADMINISTRATION: Require Airbus to develop a modification for in-service A320 family aircraft such that, in the event of an AC 1 electrical bus failure, the standby attitude indicator is powered by an additional power source that will last for a minimum of 30 minutes, and require operators to incorporate this modification as soon as possible after it is available.
