INCIDENT: Rudder Cable wear in C172S aircraft

[old man emu]

Not strictly RAA, but relevant to the article in this month's Sport Pilot.

 

We had two flying school C172S airplanes in the shop for periodic inspections at the end of last week. These airplanes were produced with stainless steel control cables, and there have been a number of reports of undue wear of the aileron cables.

 

As part of our inspection, we discovered that the rudder cables in both airplanes were frayed where they had come in contact with pulleys.

 

Moral of story:

 

Carefully inspect all your control cables for wear, especially in the vicinity of pulleys and fairleads.

Over the years i worked on GA i found a lot of different types with this problem. The worst i found was on a Nomad that had been operatng from the QLD mainland to the islands. Aileron cable 90% frayed at lower pully. Obviously never checked.
