FAR 91 under IFR requires reports on many things, unforecast
weather and equipment failure are two.

I found this:

§ 91.187 Operation under IFR in controlled airspace: Malfunction
reports.
(a) The pilot in command of each aircraft operated in controlled
airspace under IFR shall report as soon as practical to ATC any
malfunctions of navigational, approach, or communication equipment
occurring in flight.

I suppose an inoperative/malfunctioning directional gyro would
qualify.

However, I don't see any mention of having the FSDO inspector signoff
before return to service.

There is some mention of reporting inoperative equipment in this
appendix:

Appendix A to Part 91—Category II Operations: Manual, Instruments,
Equipment, and Maintenance

But I wouldn't think that applicable in this case.

Perhaps you'd be good enough to locate the citation that mandates FSDO
contacting the pilot when he mentions a DG malfunction:

Thanks.
