So one of the people from the Lab who was with me asked how often you have to depaint
a composite airplane.
Tom Sapien, Aircraft Paint/PMB supervisor, explained that "the depaint
process is crucial to the fleet because it's our job to identify corrosion on aircraft and arrest it before the aircraft is repainted and reinducted into the fleet." However, this step can he a challenge due to the amount of paint on the aircraft when they arrive at the depot.
Given that about 10,000 commercial airliners are flying today, the world's airlines are spending hundreds of millions of dollars a year to depaint
and repaint their airplanes.
In fact, the system was originally developed to safely clean and depaint
the Statue of Liberty.
