part66 categories

[neilmck]

Information on group categories is excessively complex for dinosaurs.
Q. Who is allowed to sign for compass swings ?
I have many B2 ratings, inc full group 3, full sub group 2a,b,and c with limitations 2,3,and 4 plus many group B1 ratings. on my old CAA licence I had mag compass and remote compass ratings, but I am now told that I can't sign for compass swings!

Not sure it applies to everything but Part 66 has a grandfather clause. The B2 LAMEs at my old work had to use that clause so they could sign for oxy, as part 66 changed it to a B1 category.
Worth looking into.
Cheers,
John

Sounds like you have been talking to Licencing who do not appear to know their own rules, it's ok sticking none aviation people in there, but i always find they appear to not know what is what..

According to the 2007 ELGD on their website


A11.2 Category B1
A category B1 certifying staff authorisation permits the
holder to issue certificates of release to service
following maintenance, including aircraft structure,
power plants and mechanical and electrical systems.
Authorisation to replace avionic line replaceable units
requiring simple tests to prove their serviceability is also
permitted.
Note: Compass compensation and adjustment
certification privileges are contained within a
Category B1 AML.
A11.3 Category B2
A category B2 certifying staff authorisation permits the
holder to issue certificates of release to service
following maintenance on avionic and electrical
systems. Category B2 certifying staff can qualify for any
A sub category subject to compliance with the
appropriate A sub category requirements.
Note: Compass compensation and adjustment
certification privileges are contained within a
Category B2 AML.
A11.4 Category C
A category C certifying staff authorisation permits the
holder to issue certificates of release to service
following base maintenance. The authorisation is valid
for the aircraft, in its entirety, including all systems


That's on page 15 of the actual document, see

I cannot see why it can possibly have changed.

Thank you NUTLOOSE and others,

Finally contacted someone in licencing who knew something, a certain ms Janet Cox (I think)
Apparently at the changeover, EASA decided that any part 66 licenced engineer could sign out compass swings, so made it an endemic (?) part of part 66 but did not tell anybody but hid it in some obscure part of EASA land paperwork.
So any part 66 licenced engineer can now sign off Compass swings without passing what was Cat X para 15 etc etc exams.
No big sweat but how many part 66 engineers know the 10 reasons for a Compass swing, how to adjust a P3 compass and so on...
What is the point of having categories if you can achieve them by post, as it were.
Excuse the bleating of an oldtime professional.
