Narrative:

Leaving sioux falls I climbed to 8000' MSL. I overheard an airliner that had left just before me report they had not yet reached the tops at 12000' MSL. Proceeding swbnd on V148 about halfway to O'neill, I encountered light rime icing at 8000' MSL. ZMP gave me block altitude from 5000-8000' MSL. Upon reaching O'neill VOR, center advised me to climb to 5400' MSL which at that time I was at 5000' MSL. I was not picking up severe airframe icing and was not able to get back to MEA altitude of 5400' MSL. At this time I was somewhere between 10-15 mi southwest of O'neill VOR. The plane was becoming hard to handle and I asked the person in the copilot seat to look and see if O'neill had an approach. He looked for a couple mins and could not find anything for O'neill. I told him to look again, that it must come alphabetical after the letter 'M.' still no luck. At this time, I tried to find it but also had no luck. By now the plane was getting too low on airspeed, so I thought it was time to take action. Center informed me at this time that O'neill had a VOR approach and told me to descend to 3600' MSL. The approach was read to me by center and another aircraft that was in the area. I did the procedure turn and did the approach to O'neill. If we had been able to find the approach to O'neill earlier, the situation would not have gone as far as it did. I question the order of alphabetizing for O'neill in the us government't instrument approach procedures.

Narrative: LEAVING SIOUX FALLS I CLBED TO 8000' MSL. I OVERHEARD AN AIRLINER THAT HAD LEFT JUST BEFORE ME RPT THEY HAD NOT YET REACHED THE TOPS AT 12000' MSL. PROCEEDING SWBND ON V148 ABOUT HALFWAY TO O'NEILL, I ENCOUNTERED LIGHT RIME ICING AT 8000' MSL. ZMP GAVE ME BLOCK ALT FROM 5000-8000' MSL. UPON REACHING O'NEILL VOR, CENTER ADVISED ME TO CLB TO 5400' MSL WHICH AT THAT TIME I WAS AT 5000' MSL. I WAS NOT PICKING UP SEVERE AIRFRAME ICING AND WAS NOT ABLE TO GET BACK TO MEA ALT OF 5400' MSL. AT THIS TIME I WAS SOMEWHERE BTWN 10-15 MI SW OF O'NEILL VOR. THE PLANE WAS BECOMING HARD TO HANDLE AND I ASKED THE PERSON IN THE COPLT SEAT TO LOOK AND SEE IF O'NEILL HAD AN APCH. HE LOOKED FOR A COUPLE MINS AND COULD NOT FIND ANYTHING FOR O'NEILL. I TOLD HIM TO LOOK AGAIN, THAT IT MUST COME ALPHABETICAL AFTER THE LETTER 'M.' STILL NO LUCK. AT THIS TIME, I TRIED TO FIND IT BUT ALSO HAD NO LUCK. BY NOW THE PLANE WAS GETTING TOO LOW ON AIRSPD, SO I THOUGHT IT WAS TIME TO TAKE ACTION. CENTER INFORMED ME AT THIS TIME THAT O'NEILL HAD A VOR APCH AND TOLD ME TO DSND TO 3600' MSL. THE APCH WAS READ TO ME BY CENTER AND ANOTHER ACFT THAT WAS IN THE AREA. I DID THE PROC TURN AND DID THE APCH TO O'NEILL. IF WE HAD BEEN ABLE TO FIND THE APCH TO O'NEILL EARLIER, THE SITUATION WOULD NOT HAVE GONE AS FAR AS IT DID. I QUESTION THE ORDER OF ALPHABETIZING FOR O'NEILL IN THE U.S. GOV'T INSTRUMENT APCH PROCS.
