Boeing declined to comment other than to say it is cooperating with the investigation of the fire.
Such extensive composite repairs have not previously been performed on an operating commercial plane. So the Ethiopian Airline fire is the first chance airlines, financiers and competitors will have to see a real example of how and at what cost the repair can be done.
Carbon-composite technology and repair have been in use much longer than lithium-ion batteries. Boeing and others have had carbon fiber in military planes, such as the B2 stealth bomber, for more than 25 years.
The 787's composite skin can be patched by grinding out the damaged section, applying fresh layers of fiber and resin and then curing with heat under vacuum pressure, according to a Boeing engineer with knowledge of the process.
The work can be done on site, and repair stations have been learning to make repairs to service the plane around the world.
