Part of Concorde tail 'fell off'

British Airways has launched an urgent investigation after part of a Concorde tail rudder fell off during a flight from London to New York, the BBC has learned.

It is the fifth rudder failure on a BA Concorde since 1989, despite changes to inspection procedures aimed at preventing such incidents

Air accident investigators are concerned that the incident is “very similar” to a previous one in 1998.

The Concorde pilots said they felt a continuous vibration as the aircraft decelerated from supersonic speed on its approach into New York last Wednesday.

After a normal landing they found that part of the lower rudder on the tail fin was missing.

None of the 96 passengers or nine crew on board were injured in the incident.

Visual inspections

The airline’s fleet of seven Concordes was re-equipped with new rudders 10 years ago, following a series of problems.

But a further incident occurred in 1998, when part of a lower rudder detached, again on a London to New York flight.

A report from the Air Accidents Investigation Branch (AAIB) said that improved, non-destructive and visual inspections should have detected that the metal skin and honeycomb core of the rudder were coming apart.

BBC transport correspondent Simon Montague says investigators want to know if subsequent tightening of investigation procedures failed to work.

But the AAIB stressed that Concorde remains safe to fly, even if an aircraft loses one of the four wedges which make up the vertical tail rudder.

Pilots have found that partial loss of the rudder does not significantly affect aircraft handling.

The Civil Aviation Authority, which regulates safety, says it has a continuing programme of monitoring Concorde rudders.

A spokesman said: “We are happy there is no safety risk, and happy for Concorde operations to continue”.

Panic

In November it was revealed that two BA Concordes had recently developed problems during transatlantic flights.

An engine failure forced one New York-bound plane to turn back to London and another flight was forced to cut its speed when cracks appeared in a window.

In another incident, engine failure forced an Air France Concorde to descend thousands of metres, reportedly causing panic on board.

November also marked the first anniversary of the return of Concorde passenger services, following the deaths of 113 people when one of the Air France planes crashed near Paris in July 2000.
