Starter Cord Pulley secure ? #90

The S4/5 starter cord is turned 90 degrees by a pulley pop rivetted into the firewall. Starting loads thus generate a 45 deg. inwards to the pilot & upwards pulling hard against the firewall steel sheet.

After long use the rivets can get loose & should be replaced before the pulley block breaks out. Firewall fatigue & cracks can also occur here around the pulley's cut out.


Have close look at least every Annual inspection & deal with any latent problem before it lets you down.
