Narrative:

Started flying GPS approach to runway 9. There was a runway change and I was vectored for ILS to runway 27. WX from ATIS was reported to be ceiling 900 ft; visibility 3 mi in rain; winds 230 degrees at 15 KTS gusting to 30 KTS. Started down the approach; broke out at 900 ft. Crosswind was coming from the left; applied left crosswind correction. Touchdown smoothly (my friends applauded). The airplane was thrown upward by a microburst. I added some power and regained control and brought it down again. The airplane then was slammed to the runway. When I taxied in; I noticed that the wind was coming from approximately 130 degrees and at least 15 KIAS (the windsock was fully extended). I called the tower to report the microburst and the wind difference. They told me that the winds were all over the compass and that they had received reports of LLWS. My next question to the tower was; 'if you had reports of windshear; why wasn't it reported on the ATIS or upon contact with the tower on approach?' the tower did not have an answer. My left propeller grazed the runway and my nose strut was pushed up. There were no injuries to any personnel or property other than my aircraft.

Title: LIGHT TWIN PILOT LANDING IN STRONG GUSTING WINDS ENCOUNTERS MICROBURST AFTER LNDG; RESULTING IN PROP STRIKE. LACK OF INFORMATION FROM TOWER OR ATIS IS CONTRIBUTING FACTOR.

Narrative: STARTED FLYING GPS APCH TO RWY 9. THERE WAS A RWY CHANGE AND I WAS VECTORED FOR ILS TO RWY 27. WX FROM ATIS WAS RPTED TO BE CEILING 900 FT; VISIBILITY 3 MI IN RAIN; WINDS 230 DEGS AT 15 KTS GUSTING TO 30 KTS. STARTED DOWN THE APCH; BROKE OUT AT 900 FT. XWIND WAS COMING FROM THE L; APPLIED L XWIND CORRECTION. TOUCHDOWN SMOOTHLY (MY FRIENDS APPLAUDED). THE AIRPLANE WAS THROWN UPWARD BY A MICROBURST. I ADDED SOME PWR AND REGAINED CTL AND BROUGHT IT DOWN AGAIN. THE AIRPLANE THEN WAS SLAMMED TO THE RWY. WHEN I TAXIED IN; I NOTICED THAT THE WIND WAS COMING FROM APPROX 130 DEGS AND AT LEAST 15 KIAS (THE WINDSOCK WAS FULLY EXTENDED). I CALLED THE TWR TO RPT THE MICROBURST AND THE WIND DIFFERENCE. THEY TOLD ME THAT THE WINDS WERE ALL OVER THE COMPASS AND THAT THEY HAD RECEIVED RPTS OF LLWS. MY NEXT QUESTION TO THE TWR WAS; 'IF YOU HAD RPTS OF WINDSHEAR; WHY WASN'T IT RPTED ON THE ATIS OR UPON CONTACT WITH THE TWR ON APCH?' THE TWR DID NOT HAVE AN ANSWER. MY L PROP GRAZED THE RWY AND MY NOSE STRUT WAS PUSHED UP. THERE WERE NO INJURIES TO ANY PERSONNEL OR PROPERTY OTHER THAN MY ACFT.
