DFC -
I'm sorry, but you are still missing the point being made.
A EASA Duplicate inspection Authorisation is not issued by a Competent Authority, but by a company. There are many pressures to get things done quickly, cheaply and with a minimum of fuss - this could potentially lead to the potentially less scrupulous operator potentially issuing an authorisation to a potentially unsuitable person.
Using a type rated Licensed Engineer, there is potentially a greater degree of confidence.
Granted some not potentially as good as others. Just as there are potentially poor licensed engineers there are potentially poor companies too, even perhaps some working for those companies.
Since only detailed information will suffice, if you take the trouble to read the BMAA Airworthiness Guide issue 7 page 21 available on the internet, you will find detailed guidance on the use of Duplicate Inspections. I would consider removing wings and things a change to primary strucutre, but I must doff my hat to you and your superioity in not needing to worry about such trivia, but this is digressing away from Part M again.
As for the CAMO, the requirements do not say how things are done, but what must be done, and by whom.
Owner owns plane,pays for everything & takes responsibility, MO Maintains plane as instructed by owner & CAMO, & CAMO controls and manages records, maintenance program maintenance data, & mandatory requirements for the plane.
I have presented the logical extreme extension to the scheme as currently presented. As I have perhaps misinterpreted the Regulations, please would you be kind enough to offer your maintenance scenario for say a PA28, covering contracts, provision and sharing of data / spares / liason etc & the authorisation of non scheduled maintenance between an owner and a seperate MO and a seperate CAMO, and remain in a controled environment?
It could well save me a great deal of aggravation for which I would be eternally grateful.
Fuji - take a peek at the EASA site, MDM032 update. Doesn't say a lot though.
Best regards
Malcom
