MAINTENANCE MANUAL
(8) Under hot and cold cycling during normal operation, “egg-shelling” of the glass envelope can
occur, or leaks may develop in the glass seal.
(9) Xenon strobe tubes can sometimes go into “self-ionization” continuously glowing a light blue,
thus rendering the system inoperative.
C. Position / Strobe Lamps Replacement
(1) Remove the screws securing the plexiglass cover to the wing tip structure, and separate the
cover from the wing tip.
(2) Remove lens retainer screws, retainer, and lens, exposing the light bracket assembly (refer to
Figure 1).
(3) The position lamps can now be replaced.
NOTE: If strobe (Xenon) lamp is to be replaced, proceed to step (5). If not complete step (4).
(4) Install lens, retainer, and cover in reverse of the preceding steps.
(5) Each strobe lamp is powered by its own power supply which is attached to a wing access
panel located on the lower wing surface just inboard of each wing tip.
CAUTION: WHEN DISCONNECTING STROBE POWER SUPPLY, ALLOW FIVE MINUTES
OF BLEED DOWN TIME BEFORE HANDLING A CHARGED UNIT.
(6) Remove the 12 screws securing wing access panel to the underside of the wing. Drop access
panel from the wing exposing the attached strobe power supply.
(7) Remove four attachment screws and eight AN960-10 washers; separate power supply from
access panel. Set wing access panel aside to protect paint etc.
(8) Unplug both power supply connectors, and remove power supply from wing.
(9) Reach into wing and unscrew (P109 left wing / P209 right wing) releasing this connector (refer
to Figure 1).
(10) Remove light bracket assembly mounting screws from wing tip and gently pull entire light
assembly free of wing tip, feeding wiring through wing tip opening until plug (P101 / P201)
three wire connector is pulled outside of wing.
NOTE: If sufficient wire length is not available to continue with the following steps, the
remaining ground wire will have to be disconnected at the plug bracket assembly
ground lug (Figure 1).
(11) Cut the disconnected three wire connector, P111 or P211, at the base of the strobe light
bracket assembly and discard cut wires and connector end.
(12) Remove and destroy Xenon strobe lamp.
(13) Route new wires attached to replacement strobe lamp through hole in bracket assembly and
install new Xenon tube in bracket assembly.
(14) Referring to 91-33-40 schematic of anti-collision strobe lighting insert new wiring terminals into
the replacement connector plug supplied with the new strobe lamp. Wire according to
schematic.
(15) Gently feed cable assembly back into wing and align light bracket assembly in place. Do not
mount assembly.
