An American Airlines Boeing 737-800, registration N956AN performing flight AA-693 from Fort Lauderdale,FL to Dallas Ft. Worth,TX (USA), was enroute at FL360 about 40nm north of Panama City,FL (USA) in instrument meteorologic conditions at 14:45Z when the captain's airspeed indications were removed from the display shortly followed by the captain's altitude indication. The crew decided to divert to Montgomery,AL (USA) and started the descent. During the descent the first officer's indicated airspeed and altitude indications were also removed from display, both engine (CFM56) electronic controls reverted to alternate mode. Using pitch/power relation as well as angle of attack indications the crew descended the aircraft into visual meteorologic conditions, where all indications recovered with engine control remaining in alternate mode, and diverted to Atlanta,GA for a safe landing about 50 minutes after leaving FL360.

A replacement Boeing 737-800 reached Dallas with a delay of 3 hours.
