Partial loss of instruments

Incident: GOL B738 near Sao Paulo on Oct 16th 2011, partial loss of instruments

By Simon Hradecky, created Wednesday, Oct 19th 2011 17:16Z, last updated Monday, Nov 28th 2011 23:20ZA

GOL Transportes Aereas Boeing 737-800, registration PR-GUL performing flight G3-1536 from Sao Paulo Congonhas,SP to Rio de Janeiro Santos Dumont,RJ (Brazil) with 95 passengers, was climbing out of Congonhas' runway 17L when the crew reported problems with the airspeed and altimeter indications, levelled off at 9000 feet and diverted to Campinas,SP for a safe landing on runway 33 about 30 minutes after departure.

A replacement Boeing 737-700 registration PR-VBW reached Rio de Janeiro with a delay of 4 hours.

The airline confirmed the flight from Congonhas (Sao Paulo) to Santos Dumont Airport (Rio de Janeiro) diverted to Viracopos Airport (Campinas) due to "unscheduled maintenance".

Passengers reported the captain made an announcement of having flight control problems and later warned passengers it would be a hard touchdown at Viracopos Airport due to failure of airspeed and altimeter indications.

A recording of communication between ATC and the aircraft in Portugese was released at http://soundcloud.com/rafaelguimar-es-1/may-day-may-day, transcribed by Francisco Meyen, translated by Francisco Meyen and AVH:
