Narrative:
Our aircraft departed L91 on a VFR (no flight plan) flight to sba. A straight line heading of 205 degrees magnetic was taken immediately after takeoff. L91 is at 796 ft MSL, our climbing took us to a cruising altitude of 12500 ft MSL (VFR). The climb out course intersected the bfl ILS course. Bfl radar was down for maintenance and bfl approach was not contacted, though a listening watch was maintained. As we intersected the bfl ILS localizer an aircraft was seen at our 10 O'clock position descending. Our aircraft was in a wings level climb. Evasive action was taken to insure that a conflict would not occur. The other aircraft may not have seen us as it did not change its flight profile. This problem can be avoided in the future by making full use of ATC facilities, even when some components (radar) are not working. Listening sometimes is not enough.

Title: A CPR LTT HAD A NMAC WHILE XING THE BFL ILS. BOTH ACFT WERE IN CLB.
Narrative: OUR ACFT DEPARTED L91 ON A VFR (NO FLT PLAN) FLT TO SBA. A STRAIGHT LINE HDG OF 205 DEGS MAGNETIC WAS TAKEN IMMEDIATELY AFTER TKOF. L91 IS AT 796 FT MSL, OUR CLBING TOOK US TO A CRUISING ALT OF 12500 FT MSL (VFR). THE CLBOUT COURSE INTERSECTED THE BFL ILS COURSE. BFL RADAR WAS DOWN FOR MAINT AND BFL APCH WAS NOT CONTACTED, THOUGH A LISTENING WATCH WAS MAINTAINED. AS WE INTERSECTED THE BFL ILS LOC AN ACFT WAS SEEN AT OUR 10 O'CLOCK POS DSNDING. OUR ACFT WAS IN A WINGS LEVEL CLB. EVASIVE ACTION WAS TAKEN TO INSURE THAT A CONFLICT WOULD NOT OCCUR. THE OTHER ACFT MAY NOT HAVE SEEN US AS IT DID NOT CHANGE ITS FLT PROFILE. THIS PROBLEM CAN BE AVOIDED IN THE FUTURE BY MAKING FULL USE OF ATC FACILITIES, EVEN WHEN SOME COMPONENTS (RADAR) ARE NOT WORKING. LISTENING SOMETIMES IS NOT ENOUGH.
