But half the problem with the paperwork issue is that it encourages the use of sub-standard parts!
Take a 50p bolt, issue an official looking piece of paper - sell it for £10.
In fixed wing aircraft there is virtually no problem in accidents directly traceable to sub-standard parts - after all it is in the financial interest of most engineers to seek them out and sell you an expensive replacement. Let alone that of the owner/pilot/maintainer of for instance a permit aircraft.
But helicopters and heavy transport aircraft - it is a problem and primarily that is due to the 50p for scrap, £100 for paper, issue. There have been a small number of accidents and a fair number of prosecutions due to fake paperwork on time-ex or scrap parts. The only reason it occurs is because of the huge diferential in price that is possible under the present arrangements.
My aircraft has a number of 'historic' repairs, dating from the days when aircraft engineers were trusted to source the right materials and use the right methods. Now that has been almost completely surplanted by the need to 'prove' the paperwork and repair scheme is 'certified'. The only effect this has had is to push up costs, it has not increased safety, simply made auditing by surveyors easier as they do not have to know anything about the specifics, just check the paper.
