British Airways engineers have complete the modifications on their 4th Concorde, G-BOAD.
Alpha Delta is now in the final stages of testing before completing a verification airtest takes place in the coming days. This aircraft has not flown since around May 2000 as it was undergoing a routine intermediate maintenance check when the Certificates of Airworthiness were withdrawn from the fleet.
If the airtest goes according to plan G-BOAD will have the CofA retuned and she will join here other 3 sister aircraft that are currently modified and in service. If necessary a second test can be carried out to fully check through any aircraft systems that do not come up the required standard during the first flight.
Concorde G-BOAC, the oldest in the BA fleet, has been rolled into the major maintenance dock in Tech Block A at Heathrow Airport to start her mod and Spar 72 repair. This is expected to take around 4 months to complete.
