Skymaster down!

Does anyone know the history on when the factory went to stainless steel cables and have any of the accidents involved stainless steel cables? I understand later production aircraft were all manufactured using the stainless steal. I have heard one report that none of the flap failures involved the stainless steal equiped aircraft. This is a significant observation if true. The source did not give permission to use his name but it's a very reliable source in the 336/337 aircraft operations. OK I like cooberation. I think thats the right word.

If you buy new flap control cables, they are stainless steel.

We replace our cables at 3000 hrs or when we add the airplane to our fleet. I've pulled out 1800 hr cables and found broken strands and I've pulled 4000 hr cables an they were good. We replace them with stainless steel and before I install the I let them soak overnight in a Mil spec cable lube that I used on Sabreliners. It takes @ 6 or 7 hrs to change them and rigg the flaps. I also found that it is easer to remove the cable pulleys rather then removing the guard pins. They can be almost impossable to get them back in and bent over.
Hope this help

The crash of the 337 doing fire work could have been caused by the pilot making 360's at low level and flying into his own wake turbulance. this may have been what happened to an O2 a few years ago doing whale surveys off the Fla coast.
