Narrative:

In sum: small aircraft pilot loses his gyroscope driven 'artificial horizon,' HSI shortly after takeoff from sgf, mo. On sgf departure frequency, in the clouds, he advises controller of difficulty in holding headings. Gets a flight assist to ict. While on ZKC frequency he assumed that ict approach control will know that he is landing at ict since other controllers had been advised. Ict was not clued in but was able to offer services. When unable on the first approach attempt, the reporter was then given a 'no gyroscope approach' by controller, eventually descending to contact approach conditions for a safe landing. Postflt inspection found that the gyroscope in the HSI was inoperative.

Title: SMA PLT LOSES HIS GYROSCOPE DRIVEN 'ARTIFICIAL HORIZON,' HSI SHORTLY AFTER TKOF FROM SGF, MO. ON DEP FREQ, IN THE CLOUDS, HE ADVISES CTLR OF DIFFICULTY IN HOLDING HEADINGS. GETS A FLT ASSIST TO ICT.

Narrative: IN SUM: SMA PLT LOSES HIS GYROSCOPE DRIVEN 'ARTIFICIAL HORIZON,' HSI SHORTLY AFTER TKOF FROM SGF, MO. ON SGF DEP FREQ, IN THE CLOUDS, HE ADVISES CTLR OF DIFFICULTY IN HOLDING HEADINGS. GETS A FLT ASSIST TO ICT. WHILE ON ZKC FREQ HE ASSUMED THAT ICT APCH CTL WILL KNOW THAT HE IS LNDG AT ICT SINCE OTHER CTLRS HAD BEEN ADVISED. ICT WAS NOT CLUED IN BUT WAS ABLE TO OFFER SVCS. WHEN UNABLE ON THE FIRST APCH ATTEMPT, THE RPTR WAS THEN GIVEN A 'NO GYROSCOPE APCH' BY CTLR, EVENTUALLY DSNDING TO CONTACT APCH CONDITIONS FOR A SAFE LNDG. POSTFLT INSPECTION FOUND THAT THE GYROSCOPE IN THE HSI WAS INOP.
