- History of Flight:
On April 30, 2026, at about 2302 local time, a Cessna 421C Golden Eagle II, N291AN, registered to KB Flies LLC out of Amarillo, TX, was destroyed when it impacted terrain near Wimberley, Texas. The pilot and four passengers were fatally injured. The flight originated from River Falls Airport (H81), Amarillo, Texas, at 2111, and was destined to New Braunfels Regional Airport (BAZ/KBAZ), New Braunfels, Texas.
According to flight tracking history, on April 20, 2026, at 1516, the airplane departed H81 on a short flight to Hereford (KHRX), Texas. At 1731, the airplane returned to H81. On April 24, 2026, at 1319, the airplane departed H81 on a flight to Lubbock (KLBB), Texas. The following day, at 0922, the airplane flew back to H81. On April 30, 2026, the airplane departed H81 on the accident flight, with the presumed destination at this point being KBAZ.
According to Automatic dependent surveillance-broadcast (ADS-B) data, the airplane entered a climbing left turn to an inflight cruising altitude of 17,000 ft. The flight appeared uneventful. At 2246:09, the airplane was tracking east, but there was weather activity present ahead of the aircraft, so a right turn was started towards the south. At about 2247:37, the airplane entered a descent from cruise altitude, and based on early flight tracking imagery, occurred at the same time as the aircraft started encountering weather activity. Several airports in the area were reporting lightning and rain. At about 2250, the airplane appeared to be in a little "zig-zag" motion with notable turns as it was descending through 15,000 ft. At 2300:00, the airplane entered a 5000 feet per minute (fpm) average rate while descending through 14,000 ft. At about 2300:46, the airplane turned right and was tracking west when it stopped the descent and entered a 7000 fpm climb back to 14,000 ft and started tracking south. However, at 2301:23, the airplane was observed again in a -7000 average rate descent back towards 11,800 ft. At about 2301:30, the airplane entered a climbing right hand turn towards 14,000 ft, but at 2301:57, the airplane was now observed on a descending right hand spiral, which the airplane did not recover from. The last ADS-B data point was recorded at 6,800 ft towards the conclusion of the spiral, the airplane was at 87 knots groundspeed with a reported average rate of -11,100 feet per minute (fpm) rate.

- Pilot Information:
Unknown at this point.
- Airplane Information:
The low-wing, retractable-landing-gear, pressurized, multiengine, 8-seat airplane, serial number (S/N) 421C0242, was manufactured in 1977. It was powered by two Continental Motors GTSIO-520 engines fitted with a RAM Conversion. The airplane was also equipped with RAM winglets and VG spoilers.
According to an old sale listing, the airplane had no damage history and was equipped for IFR flight, with the reported following avionics:
"Garmin 530 w/ XM Weather , TCAS I , Garmin 430 w/ Mode S Transponder Traffic Displayed , RDR 2000 Color Radar , Stormscope , Alt Preselect , Yaw Damp, Insight Graphic Engine Mon. , Hoskins digital Fuel Flow ,Fire detect/exting Known Ice , Fact Air"
- Wreckage and Impact Information:
Local authorities reported: "Preliminary information indicates the plane was traveling at a high rate of speed at the time of impact, and that there is no indication of a mid-air collision."
Post-accident photos revealed that the main wreckage consisted of the fuselage, both wings, and tail, which were in a wooded area and was consumed by a post crash fire. The wreckage was oriented upright and there were no angular cuts in the trees surrounding the main wreckage.
The on-scene photos suggests the main wreckage came down flat, with little to no forward speed. It is unknown if the aircraft suffered an inflight breakup during the out of control spiral, which may have led to the main wreckage coming down in this way.

.KEY MESSAGES...
- Isolated to scattered thunderstorms are forecast for the rest of today
into early Friday evening. Some could be strong to marginally
severe.

.SHORT TERM...
(Tonight through Friday night)
Issued at 114 PM CDT Thu Apr 30 2026
Latest visible imagery shows cloudy skies across most of South
Central Texas with some breaks over the Coastal Plains. A mid to
upper level shortwave moving across the Hill Country is helping
shower and thunderstorm activity across the Hill Country especially
over portions of Burnet, Blanco, and soon over Travis counties as
of 1 PM CDT. This activity could be enhanced as the afternoon
progresses with more activity expanding over parts of the southern
Edwards Plateau. Main hazards are large hail, strong to damaging
wind gusts, and localized heavy rain. We may have a lull in
activity later this afternoon into the early evening, but showers
and thunderstorms return over the Rio Grande mid to late evening
and then move eastward overnight into Friday afternoon and
possibly through early Friday evening. These storms will have the
support of an upper level short wave pushing from Baja California
into northern Mexico into west Texas and then over our local area
throughout the day Friday. There is a moderate to high confidence
on locally heavy rain across a good portion of South Central Texas
late this evening through Friday evening as several rounds of
heavy rain affect the local area. A Flood Watch is in effect from
9 PM CDT this evening through 9 PM CDT Friday. Rainfall amounts of
2 to 4 inches are forecast with isolated 6 inches for the
duration of the Flood Watch. Remember to promote the following:
Stay weather aware and away from flooded areas. As the wave moves
to the east of the local area Friday afternoon through the
evening, rain chances come to an end from west to east. Breezy
north winds are forecast to prevail late Friday afternoon through
the overnight hours with gusts of 30 to 40 mph.
&&
.LONG TERM...
(Saturday through next Thursday)
Issued at 114 PM CDT Thu Apr 30 2026
By Saturday morning, dry and cooler weather conditions are in store
as a surge of cooler airmass pushes from the north resulting in lows
around the mid 40s over the Hill Country to mid 50s across the
Coastal Plains. Saturday`s highs are forecast to range from the
upper 60s to mid 70s. A surface high pressure system over South
Central Texas Saturday evening pushes to the east overnight into
Sunday and brings back a southerly flow to the local area. With the
return flow in place, a warming trend begins on Sunday with forecast
highs in the mid to upper 70s to low 80s along the Rio Grande.
The warming trend and dry weather conditions continue at least
through next Wednesday.

.AVIATION...
(00Z TAFS)
Issued at 640 PM CDT Thu Apr 30 2026
Over the next 24 hours, several fast-moving clusters and bands of
TSRA/SHRA are expected to move west to east across the region.
Activity is forecast to be most numerous between 09Z-21Z. The 00Z
TAFs provide a general sketch of the more favored periods for TS,
but the main takeaway is that the weather will be quite active.
Rounds of more intense TSRA may be separated by SHRA or BR, with
broad lowering to IFR CIGs expected tonight. Periods of LIFR CIGs
are possible between 09Z-15Z at all TAF sites, but confidence was
too low to highlight in the TAFs. Prevailing winds will increase
towards gusty northeasterlies at KAUS/KSAT/KSSF, mainly after 17Z
with peak gusts occurring around 00Z. Hi-res models suggest gusts
of about 28-33 kt are likely. CIGs may slowly improve during the
day, especially following the last round of storms in the mid- to
late-afternoon, with the slowest improvement at KAUS and vicinity
compared to other sites.
