Narrative:

On preflight of a rental small aircraft a note in the log sheets listed '#2 navigation inoperative.' preflight otherwise ok. Thunderstorms were in area forecast for xd pm. I had flight planned for XA30 departure with 5 hours fuel for 1.5 hour flight. Avionics were state of the art, with RNAV, LORAN, stormscope, etc. Actual departure was near xc pm, so I was pushing it with the WX. 15 mins after departure I experienced complete radio failure in IMC conditions. Fortunately, I carry a handheld communication radio and was able to maintain contact with approach. I was vectored to a VFR field 20 NM southwest of home base, but prior to landing I advised approach of minimum fuel as fuel gauges indicated 3 hours fuel--less than predicted--and I was concerned about possible fuel loss from an open sump drain or hose leak. True, the gauges are 'only correct when reading empty,' but seeing low fuel gauges in IMC with a handheld radio with questionable battery charge was, to say the least, uncomfortable. The approach controller was terrific, even though thunderstorms were closing in and he was issuing deviations to mdw flts along with getting me on the ground. I never thought I'd find myself in a 'never again' magazine article situation, but hedging on thunderstorm activity with an inoperative component in IMC conditions was just that. Rental pilots must insist on equipment being in 100% operating order but must not blame the aircraft owner/operator for pilot 'get-there-itis' no matter how fancy the equipment. I will not get in an airplane again west/O a fully charged handheld radio.

Title: GA SMA EXPERIENCE RADIO FAILURE IN IMC. PLT RECEIVED FLT ASSIST USING HAND-HELD RADIO.

Narrative: ON PREFLT OF A RENTAL SMA A NOTE IN THE LOG SHEETS LISTED '#2 NAV INOP.' PREFLT OTHERWISE OK. TSTMS WERE IN AREA FORECAST FOR XD PM. I HAD FLT PLANNED FOR XA30 DEP WITH 5 HRS FUEL FOR 1.5 HR FLT. AVIONICS WERE STATE OF THE ART, WITH RNAV, LORAN, STORMSCOPE, ETC. ACTUAL DEP WAS NEAR XC PM, SO I WAS PUSHING IT WITH THE WX. 15 MINS AFTER DEP I EXPERIENCED COMPLETE RADIO FAILURE IN IMC CONDITIONS. FORTUNATELY, I CARRY A HANDHELD COM RADIO AND WAS ABLE TO MAINTAIN CONTACT WITH APCH. I WAS VECTORED TO A VFR FIELD 20 NM SW OF HOME BASE, BUT PRIOR TO LNDG I ADVISED APCH OF MINIMUM FUEL AS FUEL GAUGES INDICATED 3 HRS FUEL--LESS THAN PREDICTED--AND I WAS CONCERNED ABOUT POSSIBLE FUEL LOSS FROM AN OPEN SUMP DRAIN OR HOSE LEAK. TRUE, THE GAUGES ARE 'ONLY CORRECT WHEN READING EMPTY,' BUT SEEING LOW FUEL GAUGES IN IMC WITH A HANDHELD RADIO WITH QUESTIONABLE BATTERY CHARGE WAS, TO SAY THE LEAST, UNCOMFORTABLE. THE APCH CTLR WAS TERRIFIC, EVEN THOUGH TSTMS WERE CLOSING IN AND HE WAS ISSUING DEVIATIONS TO MDW FLTS ALONG WITH GETTING ME ON THE GND. I NEVER THOUGHT I'D FIND MYSELF IN A 'NEVER AGAIN' MAGAZINE ARTICLE SITUATION, BUT HEDGING ON TSTM ACTIVITY WITH AN INOP COMPONENT IN IMC CONDITIONS WAS JUST THAT. RENTAL PLTS MUST INSIST ON EQUIPMENT BEING IN 100% OPERATING ORDER BUT MUST NOT BLAME THE ACFT OWNER/OPERATOR FOR PLT 'GET-THERE-ITIS' NO MATTER HOW FANCY THE EQUIP. I WILL NOT GET IN AN AIRPLANE AGAIN W/O A FULLY CHARGED HANDHELD RADIO.
