This is a bit like shooting sharks after a shark attack. It does nothing to reduce the probability of another attack, but lets the regulator look like they are doing something to protect people.
There is a guy at Moorabbin Airport who specialises in making cables apparently.
Frequently its cheaper / faster to buy the new off-the-shelf replacement part from Piper, Beech, Cessna, etc.
Its not a huge amount of money when done in an orderly manner with 100 hourlys. And replacing cables at 15 years is not unreasonable. But its not logic or evidence based.
with more than one cable break
Yeah, but not many more than one and its not clear that they failed due to age rather than service conditions.
AND I would maintain that diligent service inspections should pick it up long before the cable fails.
