Narrative:

The l-hand aileron power control actuator rod end fairing was incorrectly installed with the rubber on the wrong side of the seal. The amm illustration was unclr; and the amm did not specify the position of the rubber. Upon inspection; the aileron moved freely and the seal appeared to function normally. Checking the opposite side aileron was not an option at the time due to the aircraft being masked for an ongoing paint operation. Amm did not clearly indicate the proper installation of the fairing. The paint facility is not suited to support a paint operation and a maintenance operation simultaneously; due to a shortage of lift equipment and large amount of obstructions surrounding the aircraft during maintenance.
