The use of paint automation in commercial aircraft production is being used to reduce process cycle times, provide a higher quality paint finish, lower emissions, and increase process consistency. The cost of new aircraft paint hangars and increasing production rates is driving a need for increased capacity in existing facilities by using new coatings and technology. Automating the surface preparation and painting processes for a structure as large as wide body commercial aircraft pose unique complexities where current technology is immature. Boeing has experienced paint automation success with smaller control surfaces such as rudders, horizontal stabilizers, and wings. Even in smaller aerospace production paint applications, some current technologies have proven unreliable. Details of Boeing's paint applications and technology challenges will be discussed in this paper. The benefits of increased quality, safety, and efficiency will continue to encourage Boeing and other companies to develop and implement paint automation solutions in their production operations.
