The Montreal, Canada-based International Air Transport Association has offered Brazilian authorities and Tam Airlines its assistance to Brazil and Tam Airlines in investigating last Tuesday's crash.
The main runway at Sao Paulo's Cagonhas airport, site of a crash that left more than 200 feared dead, was criticized for being too short and was scheduled for construction to improve drainage in wet conditions, airport officials said yesterday.
The runway problems were revealed after a plane skidded on landing Tuesday, crashed into a building and erupted into flames, in Brazil's deadliest aviation disaster.
The main runway had been closed between May 14 and June 29 for construction work aimed at smoothing out irregular surfacing and putting down fresh layers of asphalt, airport administrator Infraero said.
A second phase of renovation was scheduled for September to improve drainage on the runway, which at 1,900 meters is about 200 meters shorter than a runway for comparable size plane at New York's LaGuardia airport.
Further compounding the dangers of the runway was its proximity to populated areas near the center of Brazil's busy financial capital.
Witnesses said the pilot of the Tam Airlines Airbus 320, carrying 186 people on board, appeared to try and lift off again as he came to the end of the slick runway to avoid colliding with traffic and buildings nearby.
Instead, the plane careened of the runway and slammed into a building before bursting into flames. The accident was believed to have killed everyone on board as well as an unspecified number of people on the ground.
Just a day before the crash, another smaller plane with 21 on board slipped off the runway before coming to stop on the grass with two burst tires.
Globo TV broadcast recordings of an air traffic controller warning a pilot that the runway was "slippery," and another controller later warning that the runway "continues to be very slippery."
Prior to the construction work, the runway was typically closed during rainy conditions.
Brazil's judiciary had banned large airplanes from landing on the airstrip but the decision was overturned on appeal.
The International Air Transport Association (IATA) has offered its assistance to Brazil and Tam Airlines in probing the crash.
"We have offered to help the government (of Brazil) and the airline," Steve Lott, a spokesman for the Montreal-based IATA said.
"There is so many factors at play here. We are not an accident investigator. We are not going to speculate on what happened but we would encourage an open, and vigorous, and thorough investigation," he said.
The International Civil Aviation Organization, which is responsible for aviation standards, said it would wait for the results of an investigation before commenting.
