That's what worries me
ASFKAP. I've worked on aircraft maintained by A & Ps and found the wiring is generally in terrible condition. The one exception was a Sudanese B707. I expected that to be a bag of worms but it turned out the best I've ever seen. The worst I've ever seen in any aircraft that was still flying (airworthy isn't the right word) was in one of the FAA's own navaid calibration aircraft. [Not to mention the spewing battery electrolyte - caused by a badly maintained charging circuit - that was busily eating its way through the aft pressure bulkhead.]
Now the JAA/EASA is busy taking electrical maintenance away from elctrical/electronic specialists and handing it over to people with inadequate training and experience in maintaining electrical equipment. Don't tell me that the old hands will continue with the wiring work, because they won't. Take away approval money and watch how the guys retire to the crew room!
[The A & C guys already think we spend most of our time in there anyway
]
In my experience most of the damage to wiring is due to drilling swarf that gets into the bundles when heavies drill out rivets without properly covering wiring or getting the electricians out of the crew room to move the bundles out of the way. Pressure to save time? - in other words cost cutting by taking short cuts. Then there's the guys who move the wiring out of the way for access to a fiddly bit and don't bother to get an electrician to come and do the job properly.
Our regulators are busily cutting another hole in one of Jim Reason's Swiss Cheeses here...
Who'll cop the blame when the inevitable accident occurs? It won't be anyone from the regulators, that's for sure!
