Before
A650 Wingtip Strobe Light Installation on Later Model
Cessna Wingtips with Shortened Light Base
Because Cessna has modified the Type E Series Wingtip Navigation Light, by
cutting off the back 1.3 inch, and designed their wingtip to fit in closer to the
light, it will be necessary to do a little fiberglass work when completing this
installation. The A650 can be installed on these Cessnas in the manner below,
and instructions above.
1. Remove the wingtip and the navigation light assembly.
2. Take a complete Model W1285 navigation light with an A650 head assembly
installed, or an A650-PR or -PG, and place it in position on the wingtip. Mark
around the navigation light base plate to get an outline of the navigation light
profile on the wingtip.
3. File or trim away the excess wingtip material, to allow the navigation light
and the A650 strobe light assembly to fit neatly in place. Allow at least 0.060
inch clearance around the A650 strobe head assembly and the wingtip.
4. To fill in the hole in the wingtip made by this trimming, and to provide a
platform for the navigation and strobe light assembly, mount the naviga-
tional light base plate on the wingtip using the two (2) forward screws with
a sheet of polyvinyl between the wingtip and the base plate for a parting
agent. Tape the polyvinyl back over the wingtip to form a seal, so it is pos-
sible to apply a polyester resin putty, or epoxy putty like "Bondo", on the
inside of the tip. Build up the trimmed area with this putty, as to have about
1/4 inch of material under and in back of the base plate. Prepare the surface
and the putty material in accordance with the putty manufacturer's instruc-
tions, to assure a good bond to the wingtip.
5. Remove the navigation light base plate and parting agent.
6. To improve the appearance of this installation, fill the indentation on the
outside of the wingtip with the aforementioned putty, and file the excess
material to a clean profile before painting.
7. Drill the third mounting screw hole for the navigation light, and complete the
installation, reference the enclosed information.
