BA completes Concorde fuel tank liner modification on one aircraft

28 June 2001


British Airways PLC said it has completed the fuel tank liner modification programme on one of its Concorde aircraft and is ""on track"" for a resumption of services later this summer.

It said Alpha Foxtrot is the first Concorde to be fitted with new linings to its fuel tanks. The wiring in the undercarriage area has also been strengthened. BA said Air France is making ""good progress"" on the modification of its first aircraft. The new fuel tank liners -- designed by EADS, the former Aerospatiale, in Toulouse -- are made of a Kevlar-rubber compound. They have been designed to minimise any fuel leaks should the wing skin be punctured. Alpha Foxtrot will now undergo extensive ground tests to measure the effects of the liners on the fuel transfer systems and to verify the estimations that have been made regarding the potential increase in weight. This will be followed by engine and system tests and taxi trials before operational assessment flights. BA said installation of the modification will begin soon on the remaining six Concordes in the BA fleet. These results, together with the analysis of the tests being carried out by the manufacturers will then be submitted to the airworthiness authorities.
