São Paulo, 10 February 2010: TAM Linhas Aéreas, known internationally as TAM Airlines, (Bovespa: TAMM4; NYSE: TAM) and TAM Mercosur, the latter with headquarters in Asuncion, Paraguay, achieved their IOSA (IATA Operational Safety Audit) registration renewal, which is now valid until January 2012. IOSA is the civil aviation industry’s most comprehensive and accepted international certificate on operational safety.

The reassessment of IOSA registration has been granted to both airlines upon the completion of the audit carried out by ARGUS PROS, an independent organization accredited by IATA. The process involved several areas from both companies, which achieved around 940 requirements related to operational safety.

TAM has maintained IOSA registration since January 2007. The registration was validated by IATA in 2008 and again now, in January 2010. TAM Linhas Aéreas and TAM Mercosur’s registration renewal is published on IATA’s official website (www.iata.org/registry).

Launched by IATA in 2003, the IOSA program is a worldwide reference in operational safety management for airlines and it assesses their processes related to: management system, flight operations, operational dispatch, ramp operations, airports, maintenance, cargo, operational safety, and training for every area associated with the airline’s operations.

Major aeronautical authorities worldwide accept the IOSA. It is also accepted by international airline companies on codeshare agreements, dismissing overlays of same nature audits whenever a new partnership is entered into.

With IOSA registration renewal, TAM meets another requirement to join the Star Alliance, the largest global airline alliance, currently composed of 26 major airline companies worldwide. The process for integrating TAM into the Star Alliance is expected to be completed in the second quarter of 2010.

TAM strictly follows the rules and standards established by the aeronautical authorities in Brazil, the United States and Europe, in addition to those agreed by international organizations such as the ICAO (International Civil Aviation Organization). Moreover, TAM is affiliated to the most important civil aviation flight safety agencies worldwide such as the FSF (Flight Safety Foundation), the largest worldwide non-governmental organization.

The company takes an active part in IATA’s Americas Regional Flight Safety Committee (RCG), and is an effective member of the United Kingdom Flight Safety Committee (UKFSC), an association of entities and professionals dedicated to the improvement of commercial aviation flight safety within the United Kingdom.
