Anyone know where to view ruling by the FAA's chief counsel? In
particular, I'm looking for the one that that states "departure
procedures" referred to in Far 91.129(g) are only those traffic
pattern departure routes that the FAA sometimes establishes for a
particular airport. As opposed to say obstacle departure procedures.

The Summit Aviation CD has many, but not all, legal interp letters.

In any case 91.129 is not an IFR regulation. If you took "departure
procedre" in the context of 91.129 to mean ODP or SID, then everyone
departing an airport with an operating control tower would have to
follow the ODP or SID, even if they didn't have an instrument rating
and/or even if they hadn't filed IFR.
