1. Winglet Painting
A. General
Aviation Partners blended winglets may be repainted with a compatible enamel topcoat applied to an existing single coat of topcoat finish with a logo paint scheme. During the repainting, two coats of paint may be applied, but not exceeded. One color coat may be applied to the entire exterior surface of the winglet, with the exception of the mandatory masked areas defined below. A second coat may be applied above winglet station 4 for the customer logo or decorative markings. Reference APB AMM Supplement, Part I, 57-00-00, Figure 3., for winglet station 4 definition.
If the winglet has already received two full coats of enamel finish, excluding any logos above station 4, then both layers, plus any logos and decorative markings, must be stripped per AMM, Section 51-21-01.
B. Masking Requirements.
Unless otherwise approved by APB, the following areas shall be masked prior to painting. Reference Figure 701.
(1)
The three (3) polished leading edge skins from the winglet root up to, but not including the winglet tip fairing. This includes the navigation lens assembly mounted in the inboard leading edge skin.
(2)
The Drawing identified Ground Support Equipment (GSE) attach locations that are not in use with exposed threads. (If a fastener is installed at the GSE location, then masking is not required.)
(3)
Inboard surfaces at winglet station zero. Overspray allowed onto inboard upper and lower skin edges. Overspray not allowed on bulb seal. Reference Figure 701, Detail A.
(4)
The exposed portion of the aft position light glass lens.
