Narrative:

Flabob airport (rir), an uncontrolled airport near riverside, ca, held a fly-in, feb/xx/97, which I attended. When leaving flabob about XA30 PST, I attempted to contact riverside municipal (ral) tower to fly through their airspace. Ral is immediately adjacent. I was unable to transmit on either communication radio and decided to return to flabob. Because of the heavy traffic at flabob, I was unable to land. I executed a go around and decided it was safer to fly out of riverside class D to the west. I maintained 2500 ft MSL until clear of ont class C airspace, then climbed to 4500 ft. En route to toa I determined my headset had failed. I switched headsets with the passenger side and communicated normally with torrance tower, where I landed. The headset had been converted to an active noise canceling set. It has now been discarded.
