Montréal, Qc, Canada, le 17 octobre 2004

Air Transat welcomes the findings of the investigation conducted by Portuguese authorities into the emergency landing in the Azores of Flight TS 236 on August 24, 2001. Air Transat supports the recommendations included in the report, all of which apply to the industry as a whole. Air Transat President and Chief Executive Officer Allen B. Graham said: "Since the occurrence we have reviewed our training programs and enhanced our processes, in terms of both maintenance and flight operations. Passenger safety has always been and continues to be our top priority; this event is unique in our history."

The occurrence resulted from a fuel leak and a complex combination of events and risk factors, including human errors, all of which are analyzed at great length in the report.

Among other things, the report recommends the mandatory installation of a new warning system for detecting fuel leaks, as recommended by Airbus to all operators in 2002. The report acknowledges that it had been difficult for the crew of Flight TS 236 to identify and subsequently isolate the fuel leak. Other recommendations aim at improving maintenance and training processes. Also recommended is a review of checklists.

The investigation was led by Portuguese authorities. Canada, France, the United Kingdom, Air Transat, Airbus and Rolls-Royce also participated.

"On behalf of the entire Air Transat team, I would like to reiterate our sincere regrets to the passengers, for whom it was undoubtedly a very difficult experience. Also, I would like to underline the professionalism shown by our crew on that occasion. Every one of them did their very best to perform their duty and put the safety of everyone on board first," said Mr. Graham.

Following the occurrence, Air Transat developed and implemented a comprehensive action plan that was submitted to Transport Canada, and took additional precautionary initiatives. Among others:

· A comprehensive review of its maintenance and operations program that led to an improvement of the performance of its quality assurance activity.
· The introduction of human factors training for all technical personnel.
· Fuel leak scenarios have been integrated into simulator training programs.
· The introduction of a new Safety Management System.
· The introduction of the new fuel leak detection system on Airbus A330 aircraft.
