Unsafe condition
This AD was prompted by reports of intermittent or blank displays of a certain integrated display unit (IDU) in the flight deck. We are issuing this AD to prevent IDU malfunctions, which could affect the ability of the flightcrew to read primary displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flightcrew to maintain control of the airplane.
Affected ADs
This AD replaces AD 2012-24-10, Amendment 39-17280 (77 FR 73908, December 12, 2012).
