We were having it specifically with the R bleed air source fail in a plane, but usually the light would extinguish before you got the checklist out and did it, usually no more than 5 seconds or so. It seemed to be some kind of indication issue. Good luck, the nextants seem to be more quirky than the old As and XPs maintenance wise.
In training they have been telling us that all Nextants have been experiencing the momentary bleed source fail light either L or R. They are telling is as long as it goes out in about 15 seconds it's a nuisance light.
