Narrative:

En route from willmar, mn, to salina, northeast, omaha approach advised of precipitation returns approximately 25 mi southwest of sioux city. Upon my request, no pilot reports were available. Trace ice was encountered as I spoke with flight watch regarding en route WX for the remainder of the flight. Flight watch had no PIREPS for the area. Upon switching back to omaha I requested an altitude change to 12000 ft MSL from 10000 ft MSL which was granted. Ice continued to form slowly at 12000 ft. I decided to divert to the nearest airport and executed a turn from 219 degrees to approximately 320 degrees as I proceeded direct to columbus, northeast, for the localizer runway 14 approach. Standard instrument approach procedure including procedure turn was executed as omaha was unable to provide radar vectors for the approach. Greater than normal approach speed was targeted for landing due to formation of ice. The aircraft landed hard. Postflt inspection revealed propeller strike, damage to landing gear doors and tail tie-down points. It is my belief decreased airflow efficiency due to accretion of ice to be the reason for the incident. Callback conversation with reporter revealed the following information: reporter said he was flying a rented aircraft. He said the FAA may be trying to get him for careless and reckless for taking off in the first place. He added he was accustomed to an approach speed of 80 KTS in the aircraft but, because of the ice, he made his approach at 85-90 KTS. At its worst, he estimates he had 1/8 to 1/4 inch of ice. He said ATC was very helpful.

Title: PLT IN A MOONEY M22 COLLECTS SOME AIRFRAME ICE AND MAKES A HARD LNDG BECAUSE OF IT.

Narrative: ENRTE FROM WILLMAR, MN, TO SALINA, NE, OMAHA APCH ADVISED OF PRECIPITATION RETURNS APPROX 25 MI SW OF SIOUX CITY. UPON MY REQUEST, NO PLT RPTS WERE AVAILABLE. TRACE ICE WAS ENCOUNTERED AS I SPOKE WITH FLT WATCH REGARDING ENRTE WX FOR THE REMAINDER OF THE FLT. FLT WATCH HAD NO PIREPS FOR THE AREA. UPON SWITCHING BACK TO OMAHA I REQUESTED AN ALT CHANGE TO 12000 FT MSL FROM 10000 FT MSL WHICH WAS GRANTED. ICE CONTINUED TO FORM SLOWLY AT 12000 FT. I DECIDED TO DIVERT TO THE NEAREST ARPT AND EXECUTED A TURN FROM 219 DEGS TO APPROX 320 DEGS AS I PROCEEDED DIRECT TO COLUMBUS, NE, FOR THE LOC RWY 14 APCH. STANDARD INST APCH PROC INCLUDING PROC TURN WAS EXECUTED AS OMAHA WAS UNABLE TO PROVIDE RADAR VECTORS FOR THE APCH. GREATER THAN NORMAL APCH SPD WAS TARGETED FOR LNDG DUE TO FORMATION OF ICE. THE ACFT LANDED HARD. POSTFLT INSPECTION REVEALED PROP STRIKE, DAMAGE TO LNDG GEAR DOORS AND TAIL TIE-DOWN POINTS. IT IS MY BELIEF DECREASED AIRFLOW EFFICIENCY DUE TO ACCRETION OF ICE TO BE THE REASON FOR THE INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID HE WAS FLYING A RENTED ACFT. HE SAID THE FAA MAY BE TRYING TO GET HIM FOR CARELESS AND RECKLESS FOR TAKING OFF IN THE FIRST PLACE. HE ADDED HE WAS ACCUSTOMED TO AN APCH SPD OF 80 KTS IN THE ACFT BUT, BECAUSE OF THE ICE, HE MADE HIS APCH AT 85-90 KTS. AT ITS WORST, HE ESTIMATES HE HAD 1/8 TO 1/4 INCH OF ICE. HE SAID ATC WAS VERY HELPFUL.
