- History of Flight:
On November 24, 2025, at about 1714 local time, a privately-registered Socata TBM700C2, N111RF, was destroyed when it was involved in an accident near Monroe Municipal Airport (EFT/KEFT), Monroe, Wisconsin. The pilot and passenger sustained fatal injuries. The personal flight originated from the Oshkosh-Wittman Field (OSH/KOSH), Oshkosh, Wisconsin, and was destined to KEFT. Nighttime instrument meteorological conditions prevailed at the time of the accident.
According to preliminary Automatic Dependent Surveillance – Broadcast (ADS-B) data, the airplane departed runway 18 at Oshkosh and proceeded to an inflight cruising altitude of 8,000 ft. The flight appeared uneventful. About 20 minutes into the flight, the airplane started its descent towards Monroe. At about 1707 LT, the airplane entered a left turn to join the RNAV (GPS) runway 12 approach at KEFT. The airplane did not appear to be correctly aligned, but was at the correct altitudes. At 1711, the airplane was at 2800 ft, 139 knots groundspeed, and descending 640 feet per minute (fpm) when it reached point IGOGY. At 1712:41, the airplane was one mile from the runway at 1,500 ft, 109 knots GS, and descending 700 fpm when it entered a climbing left hand turn to 1,800 ft. At 1713:04, the airplane was at 1,700 ft, 158 knots GS, with an average rate of about -2240 fpm. The next data point showed a rate of -5888 fpm. At 1713:13, the airplane was at 1,200 ft, 147 knots GS, but now had a positive average rate of about 9920 fpm. The next few data points showed a very aggressive left hand climbing turn, with a reported average rate of about 12,000 fpm. This turn put the aircraft on a 89 degree (east) track heading, and concluded at 1713:24, when the airplane was at 3,000 ft, 52 knots GS, with a positive rate of 1280 fpm. The next data point was the last one recorded. The airplane was seen at 1,700 ft, 82 knots GS, with an average rate of -16,700 feet per minute (fpm). This point was recorded over a gravel query located 0.36 mile north of runway 20.
The FAA reported that the aircraft crashed under unknown circumstances in the query.

- Pilot Information:
Unknown at this point.
According to public FAA records, the current registered owner holds a private pilot certificate (issued/updated on 5/21/2010) with a rating for airplane single engine land and an instrument rating. His first class FAA medical was issued in January 2025, with a note that he must wear corrective lens(es) to meet vision standards at all required distances.
- Airplane Information:
The airplane, a Socata TBM 700 C2, serial number 268, was manufactured in 2003. The low-wing airplane was of conventional aluminum construction and was equipped with a retractable tricycle landing gear and a pressurized cabin that was configured to seat six individuals. The airplane was powered by a 700 shaft-horsepower Pratt & Whitney Canada PT6A-64 turbo-propeller engine, through a 4-blade, constant speed, full-feathering, Hartzell propeller assembly. The airplane was approved for operations in instrument meteorological conditions and in known icing conditions. The airplane had a maximum allowable takeoff weight of 7,394 pounds. The airplane was registered to the current owner/operator on 01/22/2016.
The airplane had two fuel tanks, one located in each wing, and a total fuel capacity of 290.6 gallons (281.6 gallons usable).
According to the Socata TBM 700 C2 Pilot Operating Handbook (POH), Supplement No. 41, the aerodynamic stall speed at maximum takeoff weight with the landing gear and flaps extended for landing is 65 knots. The aerodynamic stall speed at maximum takeoff weight with the landing gear and flaps extended for takeoff is 77 knots. The aerodynamic stall speed at maximum takeoff weight with the landing gear and flaps retracted is 83 knots. The approach speed with flaps in the landing position is 85 knots.
- Wreckage and Impact Information:
There are no known photos from the accident site.
- Airport Information:
Monroe Municipal Airport is a non-towered public airport located 3 miles northeast of Monroe, Wisconsin. The airport field elevation was 1085.5 ft. The airport features two runways, runway 12/30, and runway 2/20. There is an RNAV (GPS) approach for runway 12 and 30, and a VOR/DME approach to 30.
The charted LNAV MDA minimums at KEFT are a descent altitude of 1480 feet msl (300 feet agl), and a visibility of 1 mile.
According to the approach plate, during a missed approach procedure, the aircraft must climb to 3000 direct FALKN and on a track 143 to DAVIS and hold.
There was an active NOTAM at the time (!EFT 10/004 EFT RWY 12 PAPI U/S 2510202208-2604202359) indicating that the runway 12 Precision approach path indicators (PAPIs) were unserviceable.

.SHORT TERM...
Issued 230 PM CST Mon Nov 24 2025
Rest of Today through Wednesday:
We continue to expect low clouds and some fog as well as
mist/drizzle to push in over the next several hours though it
has bee much slower to push in than previously thought. It still
remains uncertain on how quickly this will occur but it at least
appears likely to happen at some point. The other uncertainties
more have to do with how impactful the fog will be once it moves
in. Some dense fog will be possible, especially overnight. In
addition some patches of light rain may push in as well, likely
due to the PVA from the weakening trough aloft, some WAA, with
enough midlevel moisture to support some showers. Regardless
drizzle and mist look to remain likely for much of the area
given the low level moisture and minor low level forcing.
However, southern WI still in large part expects to be missed by
the vast majority of the better forcing to the north and
southeast that would bring better rain amounts. We may be able
to expect some better rain chances in far southeast WI and
toward central WI later tonight into Tuesday morning.
As the warm front lifts through tonight we may dry out into
Tuesday, though drizzle will remain possible. We should also
expect to warm up a bit with southerly winds but clouds will
likely keep temperatures from escaping the low 50s. The cold
front will then be expected to swing through Tuesday
evening/night bringing the best chances (60-80%) for widespread
rain showers. With the surface low becoming fairly strong this
will help usher in some very chilly air by late Tuesday night
into Wednesday morning. Given that we will still have the
surface low in the region with some TROWAL effect we could
easily see some snow on the backside of this system. In fact it
cannot be ruled out that we see some mild accumulations up to an
inch on the northern side of the CWA over the course of the day
Wednesday.
With a strong LLJ aloft, winds will significantly increase by
early Wednesday morning with afternoon wind gusts over the land
having potential to reach Wind Advisory criteria, especially
closer to the lake.

.LONG TERM...
Issued 230 PM CST Mon Nov 24 2025
Wednesday night through Monday:
Winds will come down a bit Wednesday night as the LLJ weakens
and the low pushes further east but we expect to remain breezy
into Thursday. Given the continued breeziness and very cold
conditions ushered in by the cold front expect wind chills in
the single digits Thursday morning. Forecast 1000-500mb
thicknesses are expected to reach near 515dam from Thursday
morning through Friday morning. This will keep very chilly
temperatures through that period. Wind chills Friday morning
will also reach the single digits but that will largely be
because of cooler temperatures but weaker winds overall. Likely
less cloud cover Friday due to higher pressure overhead will
contribute to lower temperatures.
Into Saturday, attention quickly turns to the uncertainty in the
forecast of an upper level trough to the west and various
embedded disturbances that will play a substantial role in the
potential for an impactful winter system. Currently the
uncertainty is such that no discernible outlook would properly
encompass the situation as there is timing, phasing, and track
issues with this next system that each of which will greatly
change the impact of this system. Various models bring some
light snow ahead of the main system which brings largely rain
while other models suggest mostly snow, early arrival, and
substantial accumulation potential. While uncertainty is
massive, it remains something to keep an eye on as the impacts
could be significant if it trends toward a compact, panhandle
hook scenario that we remain on the cool side of. In addition
this impacts the forecast into early next week with substantial
temp differences within ensembles given the differences in the
development and progression of the upper low/trough over the
weekend.

.AVIATION...
Issued 230 PM CST Mon Nov 24 2025
The onset of aviation impacts today has been delayed likely by
some low level dry air. However, LIFR/IFR CIGS with MVFR to IFR
VSBYS are finally starting to push in from the southwest this
afternoon with impacts to VSBYS and CIGS expected for much of
southern WI over the next several hours but may be until tonight
before is fully encompasses southern WI. Drizzle/mist will also
be likely given the abundant very low level moisture. There is
some uncertainty on how widespread the lowest VSBYS get and how
low but some quarter mile VSBYS seem possible, particularly
later tonight. CIGS look much more likely to be LIFR, perhaps
even some VLIFR with some periods of MVFR/IFR as the lower end
CIGS push in. The timing looks focused for tonight. The best
chances for rain this evening and tonight appear largely focused
for west central and far southeast WI.
Some VSBY and CIG improvement is expected into the day Tuesday
but generally expected to remain IFR at least and continuing
through Tuesday night.
