Last week, I was doing approaches in actual IMC, and returning back to MBO
(Madison, MS), I broke out right at minimum ceilings 4.8 miles DME from the
JAN VOR. Ceilings were just above 900 feet. Missed minimums are 5 DME an
900 feet ceilings (NOTAM raised it from 860 to 900).

The approach takes you into a 45 degree entry for downwind for runway 17 or
midfield for 35 circle to approach. There was a plane at the end of
taxiway 35 waiting for his clearance for take off.

This got me to thinking.....

Had I broke out of the clouds at mid field at 5 DME from the JAN VOR, what
would be the proper procedure for landing on 35? Winds were blowing from
340 at 21 knots gusting to 29 knots. Airport has a left hand pattern.

Would it be "acceptable" to cross mid field and execute a right hand
pattern entry? No noise abatement issues at this airport.

In my opinion, there are two issues here. One is regulatory:

================================================== ==============
§ 91.126 Operating on or in the vicinity of an airport in Class G
airspace.

(a) General. Unless otherwise authorized or required, each person operating
an aircraft on or in the vicinity of an airport in a Class G airspace area
must comply with the requirements of this section.

(b) Direction of turns. When approaching to land at an airport without an
operating control tower in Class G airspace—

(1) Each pilot of an airplane must make all turns of that airplane to the
left unless the airport displays approved light signals or visual markings
indicating that turns should be made to the right, in which case the pilot
must make all turns to the right ...

§ 91.127 Operating on or in the vicinity of an airport in Class E
airspace.

(a) Unless otherwise required by part 93 of this chapter or unless
otherwise authorized or required by the ATC facility having jurisdiction
over the Class E airspace area, each person operating an aircraft on or in
the vicinity of an airport in a Class E airspace area must comply with the
requirements of §91.126.

================================================

Sure, the situation could "require" that you make a turn to the right; or
you could get "authorized" by ATC; but you might have to justify your
decision if you felt that it was "required", especially if you did so
without authorization, and there was some incident.

The second (and probably more important) issue has to do with avoiding
possible VFR traffic in the area/pattern that is executing normal left hand
traffic. I believe KMBO is Class G below 700'. If so, the VFR minima are
1 mile/clear of clouds. There certainly could be VFR traffic operating
to/from the airport legally in the Class G with 900/5 weather.

I've done that myself going from a water takeoff to a land airport (KLCI)
served by instrument approaches under conditions similar to what you
describe. All legal. I don't know if seaplanes are allowed on the
reservoir to the east of your airport, but that might be one source of VFR
traffic other than folk in the pattern.
