Narrative:
We were cleared for the civet profile descent to runway 35 at lax. Just prior to reaching fuelr fix, we realized we had lost radio contact with approach control. We tried to make contact on other approach frequencys, on tower and 121.5. We also tried our #2 VHF radio. When it became apparent that we had lost all communications, we squawked 77000 and transmitted in the blind that we were continuing an ILS approach to runway 25 at lax. After we were inside the FAF (limma) we regained radio contact with lax tower and received a clearance to land.

Narrative: WE WERE CLRED FOR THE CIVET PROFILE DSCNT TO RWY 35 AT LAX. JUST PRIOR TO REACHING FUELR FIX, WE REALIZED WE HAD LOST RADIO CONTACT WITH APCH CTL. WE TRIED TO MAKE CONTACT ON OTHER APCH FREQS, ON TWR AND 121.5. WE ALSO TRIED OUR #2 VHF RADIO. WHEN IT BECAME APPARENT THAT WE HAD LOST ALL COMS, WE SQUAWKED 77000 AND XMITTED IN THE BLIND THAT WE WERE CONTINUING AN ILS APCH TO RWY 25 AT LAX.
