Maintenance Practices

1.  General
This procedure describes the replacement of the lamp for the forward navigation light located in the winglet leading edge.  This procedure includes instructions for both, a winglet equipped with “Halogen” forward position lights, and a winglet equipped with “LED” forward position lights.
Note: For winglets equipped with “Halogen” lights, the forward position light consists of two (2) lamps, which are accessed by removing the forward position light lens.  For winglets equipped with “LED” lights, re-lamping requires the removal and replacement of the LED Module Assembly.  Access to the LED Module for replacement is achieved by removing the forward position light lens for front side access, and removing the winglet lower access door for backside connector access.
