I would beg of my colleagues one unconfusion factor when we read these things.
1. It is true that an Inspection Authorization is only given to a current Airframe and Powerplant mechanic.
2. A mechanic may not sign off an annual.
3. An inspector may not repair an airplane.
When the A&P/IA signs off on an annual, (s)he is doing it as an INSPECTOR.
When the A&P/IA repairs an airplane (s)he is doing it as a MECHANIC.
Not all A&Ps are IAs. All IAs are A&Ps.
When you are referring to the mechanic as signing off the annual, it gives at least me the heeby-jeebies that some A&P is signing off that which (s)he can't. When it refers to the fellow that signed off the annual doing the repairs it doesn't much bother me.
And yes, an IA can sign off as inspected the work (s)he did as a mechanic.
I know Tom has done this a hundred times, but after 40 years as an A&P and 20+ years as an IA, I finally signed a 337 (Major Repair/Alteration) on which I played ALL 3 parts ... an aviation hat trick, as it were.
I entered it as the owner of the airplane, signed the installation of an ADSB as the mechanic, then approved my own work as the IA. It seemed kind of funny, but them's the rules.

That's the sad part part Jim, we work with out a safety net of a QA department, we must be perfect every time or pay the price.
I built the Fairchild from bare steel fuselage out for over 11 years, I had every system apart, and back together again, built many new parts from scratch. the return to service entry was 5 pages long, every system had been tested, checked, and was known to work as it was designed.
It flew day one 4 hours with no discrepancies.
N2623V same - 2 years in work
N3934V same -2 years in work
N2801C Same- 6 months major repair & restoration
N6988S Same - 1 year rebuild from salvage.
The time an aircraft is most vulnerable is after maintenance.
IMHO the most important phase of an Annual is the Pilots pre-flight inspection. We as mechanics work a dual roll when we do annuals, we both fix and inspect, we use all of our certificates "AP"xxxxxxx"IA".
To me, going flying with unresolved maintenance issues, unforgivable.
