TAM Linhas Aéreas Flight 3054 (JJ 3054) was a scheduled domestic passenger flight between Porto Alegre and São Paulo, Brazil. It crashed upon landing during rain in São Paulo on July 17, 2007.[7] The Airbus A320 overran the runway, crossed a major thoroughfare during rush hour, crashed at high speed into a TAM Express warehouse adjacent to a gas station and exploded.[8][9] There were 187 people on board: 181 passengers, 19 of whom were TAM employees, and 6 crew members.[2][3] All passengers and crew were killed in the crash,[10] in addition to twelve people on the ground.[5] This is Latin America's worst aviation accident to date and the worst accident involving an Airbus A320 anywhere in the world.[11]

Aircraft

The aircraft was an Airbus A320-233 registered as PR-MBK and manufacturer's serial number of 789. It was powered by two International Aero V2527E-A5 engines. According to Flight International, the aircraft was built in February 1998 and first entered service in March flying for Grupo TACA and later in November 2003 by Pacific Airlines. The aircraft was owned by Pegasus Aviation, prior to the crash, and entered into service for TAM in December 2006. As of April 20, 2007, the aircraft had flown 20,379 hours over 9,313 cycles.[1]

The aircraft was dispatched with the thrust reverser, a mechanical device to help slow the airplane down on landing, on the number 2 (right-side) engine deactivated as it had jammed. TAM said in a statement that a fault in a reverser "does not jeopardize landings."[12] In the same statement TAM also said "no mechanical problem had been recorded on July 16" (the day before the accident)."[12] However, it was reported that the plane had difficulty braking on the same runway only one day prior to the fatal accident.[13] The inactivated thrust reverser on the number 2 engine was confirmed by Airbus on July 25.[14]

Flight chronology

The plane departed from Salgado Filho International Airport in Porto Alegre at 17:16 local time (20:16 UTC). It crashed upon landing at Congonhas-São Paulo International Airport in São Paulo at 18:50 local time (21:50 UTC).

Flight 3054 was cleared to land at Congonhas' 35L runway. Reviews by government officials of the surveillance videos showed that despite the aircraft touching down at the normal touch-down point on the runway, it did not slow down normally, crossing the far end of the runway at around 90 knots (103 mph, 162 km/h).[15] The aircraft, bearing to the left, continued off the end of the runway, clearing, barely airborne, the airport perimeter fence. The runway is elevated above the surrounding area, and the aircraft's momentum carried it over the traffic on the adjacent Avenida Washington Luís, a major thoroughfare. After clearing the road, the aircraft exploded on impact with a four-story TAM Express facility, resulting in a large fire. The TAM Express building contained offices and a warehouse, and was located adjacent to a gas station.[16]

The runway had recently been resurfaced, but it did not yet have water-channeling grooves cut into it to reduce the danger of hydroplaning.[7]

Flight Data Recorder (FDR) information recovered after the crash and released by Brazilian authorities, showed that immediately prior to touchdown, both thrust levers were in CL (or "climb") position, with engine power being governed by the flight computer's autothrottle system.[17] Two seconds prior to touchdown, an aural warning, "retard, retard" was issued by the flight's computer system, advising the pilots to "retard" the thrust lever to the recommended idle or reverse thrust lever position. This would disengage the aircraft's autothrottle system, with engine power then being governed directly by the thrust lever's position.

At the moment of touchdown, the spoiler lever was in the "ARMED" position.[17] According to the system logic of the A320's flight controls,[18] in order for the spoilers to automatically deploy upon touchdown not only must the spoiler lever be in the "ARMED" position, but both thrust levers must be at or close to the "idle" position. The FDR transcript shows that immediately after the warning, the flight computer recorded the left thrust lever being retarded to the rear-most position, activating the thrust reverser on the left engine, while the right thrust lever (controlling the engine with the disabled thrust reverser) remained in the CL position. The right engine accelerated to a power setting corresponding to the "climb" position of the thrust lever, while the left engine deployed its thrust reverser. The A320's spoilers did not deploy during the landing run, as the right thrust lever was above the "idle" setting required for automatic spoiler deployment.[17]

Air safety in Brazil has been under increased scrutiny recently following the mid-air collision in September 2006 over the Amazon of Gol Transportes Aéreos Flight 1907 and an Embraer Legacy 600 (see Brazil's 2006-2007 aviation crisis). Congonhas has been singled out for having safety issues relating to operations in wet weather due to its location and runway characteristics for the traffic it serves.

The 35L runway at Congonhas is 1,940 metres (6,365 feet) long. Congonhas' counterpart in Rio de Janeiro, the Santos Dumont Airport, has an even shorter runway, at 1,323 metres (4,341 ft). Both airports receive the same type of traffic — ranging from small private planes to Boeing 737s and A320s. Many variables affect the landing distance of an aircraft, such as approach speed, weight and the presence of either a tailwind or a headwind. For an Airbus A320, a speed of just 20 knots higher than normal can result in as much as a 25% increase in the runway length needed to stop an aircraft. Wet weather can also significantly reduce the braking performance of aircraft, leading to an increase in the minimum runway length requirement.[19] As water accumulation in the runway at the time of the crash was not significant, the focus of the investigation shifted away from runway hydroplaning concerns.[13]

In February 2007, a Brazilian judge briefly banned flights using Fokker 100, Boeing 737-700 and Boeing 737-800 aircraft in and out of the airport. The Airbus A320 was not among the aircraft banned, due to its manufacturer-stated braking distance being shorter than those of the banned aircraft. Pilots had complained that water had been accumulating on the runway reducing aircraft braking performance and occasionally causing planes to hydroplane. The judge claimed the runway needed to be 388 metres (1,275 ft) longer for these aircraft to operate safely. At the time, a spokeswoman from Brazil's National Civil Aviation Agency claimed "The safety conditions of the runway and the airport as a whole are adequate."[20] TAM also objected to the decision with a spokesman stating "If the injunction stands, it will cause total chaos" claiming over 10,000 passengers per day would be inconvenienced.[20] The airport authorities appealed the decision, resulting in it being overturned the following day. An appeals court overruled the ban on the three types of planes, saying it was too harsh as it would have severe economic ramifications and that there were not enough safety concerns to prevent the planes from landing and taking off from the airport. "The runway was reopened because of popular pressure," Gianfranco Beting, an aviation consultant, said in a TV interview.[21]

Aftermath

The airport reopened on July 19 using an alternate runway.[13]

Many flights, including all OceanAir and BRA Transportes Aéreos, were transferred to Guarulhos International Airport, the second major airport in São Paulo due to the closure of the main runway at Congonhas and the ongoing investigation of the accident.

On July 20 minister Dilma Rousseff of Casa Civil (Civil House, part of the federal government) announced plans to significantly reduce the number of flights operating at Congonhas. The plan includes banning all connection, stopover, charter, and international flights and the reduction in the number of private jets within 60 days. The airport will only operate direct flights to certain cities in Brazil. The plan also calls for a study of the expansion of São Paulo's two current airports and the construction of a third airport in the metropolitan area.[22]

State crime scene investigators terminated the search for remains on July 28 2007;[23] as of that date, 114 bodies recovered from the site had been identified by the São Paulo Medical Examiner's Office as those of passengers.[24]

Investigation

The aircraft was an Airbus A320, similar to the one pictured here.

The investigation is being carried out by Brazil's Centre for the Investigation and Prevention of Aeronautical Accidents (Centro de Investigação e Prevenção de Acidentes Aeronáuticos, CENIPA). Data from the flight data recorder and cockpit voice recorder (CVR) were downloaded by the National Transportation Safety Board in the United States commencing July 20 and July 23 respectively.[14][25] Based on preliminary data from the FDR, on July 25 Airbus cautioned A320 operators to ensure that both thrust levers are set to idle during flare.[14] The transcript of the CVR was released on August 1.[26] It shows that the pilots were aware of the wet runway conditions and the deactivated thrust reverser.[27] The pilots' comments suggest that the spoilers did not deploy and that they were unable to slow the aircraft.[27]

Response

After the crash, President Lula of Brazil ordered three days of national mourning.[28]

Several countries and organisations offered their condolences: Angola, Argentina, Bulgaria, Chile, China, Cuba, East Timor, the European Union, France, Germany, Ireland, Israel, Mexico, Oman, Pakistan, Panama, Peru, Portugal, Russia, South Africa, Spain, Tunisia, United States, Vatican City[29] and Venezuela.

During the 2007 Pan American Games in Rio de Janeiro, the Brazilian athletes wore a black armband in remembrance of the victims.[30] The flags of all participating countries were flown at half mast on July 18. Matches involving a Brazilian athlete or team started with a minute silence.

All matches of the Campeonato Brasileiro 2007 started with a minute silence, while all players wore black armbands. Brazilian Formula One driver Felipe Massa had a black stripe on top of his helmet during the 2007 European Grand Prix, to commemorate the victims. Rubens Barrichello also had stripes on his helmet, and the two Red Bull Racing drivers David Coulthard and Mark Webber had small Brazilian flags on their helmets referring to the accident.

More than 5,000 Brazilians marched to the crash site on July 29, 2007, blaming their government's failure to invest in airport infrastructure for the crash. Many of the protesters also demanded the ouster of President Luiz Inacio Lula da Silva.[31]
