(1) Description:

The pilot stated the weather en route was 10SM visibility with a 12,000 foot ceiling. The pilot stated springfield approach cleared him for the visual approach to runway 27 at ktaz. The pilot stated, he checked the ASOS during the arrival, and again on downwind, and it was reporting winds at 290 degrees at 13 knots gusting to 20 knots. The pilot stated he was comfortable with the conditions and flew a normal full-flap approach adding a little extra airspeed (between 87-89KNOTS instead of the standard 85KTS). The pilot stated the approach was normal with a good touchdown at the appropriate touchdown distance. The pilot stated he experienced a good crosswind correction and braking action. The pilot stated there was an initial increase in wind gust. The pilot stated this additional wind gust caused the airplane to drift left off the runway centerline. The pilot stated while he was compensating for that wind gust, a second wind gust which ?exceeded the crosswind component of the aircraft? Occurred and he was unable to counter it. The pilot stated the airplane drifted uncontrollably to the left. The pilot stated the aircraft?s left main gear went off the side of the runway and sank into the soft ground. The pilot stated the subsequent drag of the left main, caused the airplane to turn hard left causing the aircraft?s nose gear to exit the runway. The pilot stated the soft ground led to the propeller striking the ground and runway before the aircraft came to a stop. The pilot stated he used his normal braking procedure on landing which was to let the aircraft rollout for a moment before adding braking. The pilot stated he usually waited even longer before using reverse propeller thrust. The pilot stated the unexpected wind gust hit the aircraft before he engaged reverse thrust. The pilot stated he later checked the ASOS again, and this time, it reported an increase in wind from 310 degrees at 30 knots. At approximately 15:15-15:30 CT, when the investigating inspector asked about a preflight weather briefing, the pilot indicated that he used foreflight to check the metars and tafs but not the weather briefing feature of the app. The pilot stated there were three passengers on board (the pilot?s wife and two children). The pilot stated there were no injuries. The pilot stated the aircraft has been assessed by daher (the aircraft manufacturer) for repairs and that it suffered a broken engine mount with firewall damage. The pilot stated the damage was sufficient enough to warrant replacement of the firewall. The pilot stated he intends to sell the aircraft after it is moved to the daher facilities in Florida.

(2) Causal and/or contributing factors:

The pilot?s failure to counteract the wind gust and subsequent departure of the aircraft off the runway.

(3) "ATC" and rational if ATC actions contributed to the event:

None.

(4) Recommendations for systemic corrective action:

Event not based on a systematic error. The pilot made a mistake in judgement and made a faulty decision based on available weather.

(5) Actions taken to address the transgression:

The pilot stated he has put new personal procedures in place to prevent this type of incident in the future.

(6) Other comments:

None.

(7) Investigation:

The investigation confirmed excessively gusty winds at the time of the accident. The investigation confirmed the pilot was qualified and current at the time of the accident. The investigation also revealed one runway light was damaged during the accident.

(8) Root cause analysis (rca):

This accident was due to the pilot?s insufficent reaction to the broadcast weather. The pilot allowed himself to be distacted, focussing on other tasks, and was caught off-guard by the increasing wind conditions.

(9) Corrective action:

Due to no regulatory violations, the investigating inspector closed the accident with no action.
