Narrative:

C421 departed oma for cos climbing to 16000 ft. Aircraft was climbing slower than normal, but could not point out to lnk because aircraft was still below their radar coverage when first noticed north of mle. Was working all position combined when numerous arrs and other aircraft called creating significant radio congestion and confusion shortly after C421 departed. Worked sequences into oma, resolving situation where ZMP put 2 arrs on top of each other. When sequencing of aircraft was done, the C421 called. The aircraft had climbed through lnk's airspace already. Had another position been open, the coordination would have been taken care of, the frequencys would not have been congested and proper focus on all sits could have been attained. Fortunately, no other aircraft were near the C421.

Original NASA ASRS Text

Title: R90 CTLR BECOMES DISTR WITH ZMP ARR SEQUENCING AND FORGETS TO POINT OUT DEPARTING SLOW CLBING C421 TO LINK APCH CTL.

Narrative: C421 DEPARTED OMA FOR COS CLBING TO 16000 FT. ACFT WAS CLBING SLOWER THAN NORMAL, BUT COULD NOT POINT OUT TO LNK BECAUSE ACFT WAS STILL BELOW THEIR RADAR COVERAGE WHEN FIRST NOTICED N OF MLE. WAS WORKING ALL POS COMBINED WHEN NUMEROUS ARRS AND OTHER ACFT CALLED CREATING SIGNIFICANT RADIO CONGESTION AND CONFUSION SHORTLY AFTER C421 DEPARTED. WORKED SEQUENCES INTO OMA, RESOLVING SIT WHERE ZMP PUT 2 ARRS ON TOP OF EACH OTHER. WHEN SEQUENCING OF ACFT WAS DONE, THE C421 CALLED. THE ACFT HAD CLBED THROUGH LNK'S AIRSPACE ALREADY. HAD ANOTHER POS BEEN OPEN, THE COORD WOULD HAVE BEEN TAKEN CARE OF, THE FREQS WOULD NOT HAVE BEEN CONGESTED AND PROPER FOCUS ON ALL SITS COULD HAVE BEEN ATTAINED. FORTUNATELY, NO OTHER ACFT WERE NEAR THE C421.
