Vertical Fin and Rudder Mounting of Anti-Collision
Strobe Lights
Rudder mounted anti-collision lights should be located top center of
the rudder hinge center line, or rudder balance must be established
after installation. Refer to AC 43.13-2A, Chapter 4, Paragraph 55(e),
"Rudder Installation". The rudder or fin cap is excellent for shadowing
the prop and cabin area if the light is mounted far enough back.
NOTE: Mounting an A450 or A470A strobe lighthead assembly on a
vertical fin or rudder, can be accomplished by fabricating a mounting
adapter similar to the ones shown in illustrations.
