OK A and C, since you don't know the requirements, let me explain them to you. They are very simple.
The first independent inspection is completed by a person qualified to complete the task and also qualified to certify the work. This person certifies the work.
The second independent inspection is completed by a competent person who does not need to hold certification privileges since they are not signing the maintenance release.
However, the mainrenance organisation has to have procedures to show that the person performing the second inspection has been trained and has gained experience.
It is not acceptable for the person signing the release (the first inspection) to show the person making the second inspection how to perform the inspection at the time it is completed.
Now to me, there is nothing new there. The second inspection must be completed by a previously trained and competent person who is familiar with the system.
Is that dangerous. If the answer is yes then the system currently used in the UK is dangerous and has been for many years.
Not much is changing. No excuse for a moan or a hike in prices for competent organisations that keep abreast of developments.
