AA Tails And Why The Different Color

Fri Jan 23, 2009 2:45 am

Always wondered - why are the vertical stabilizers (tails) on the American 757s, 767s and 777s not the shiny silver the fuselages are.I know the tails need to be weighed exactly before they are put on the aircraft, that's why you can always tell the airline when one is still being built. But why don't they just leave the AA tails the original metal. Or is it not metal and thus wouldn't match. Always wondered. And the nose cone has the same issue.

It's because of the different materials used in the construction of the different tails. Composite components need to painted differently from traditional aluminum.

I believe you answered your own question. The nose cone and vertical stabilizer outer panels are NOT metal.  Big grin

If you look at photos of older aircraft operated by AA, the tails were indeed kept bare metal. However, over time, as increasing amounts of composite material were introduced, more grey patches kept popping up on the tail surface. Eventually, AA went ahead and painted all tails grey for greater consistency:
