Narrative:

Was on final/short final as aircraft departed head-on. Only noticed aircraft after it rotated. Student and I had entered pattern on 45 degree off of VOR 'a' approach and made all appropriate radio calls. No ATIS/AWOS available at landing field. Chose runway most closely aligned with that in use at class D 10 mi east. Airport of landing has low volume of traffic usually. Radio was quiet except for 1-2 calls. Windsock showed light crosswind favoring runway we chose. Assumed runway clear. After landing, noticed that the communication selection was on speaker instead of phone and the volume low enough that could only be heard on the intercom. Audio selection was inadvertently bumped during the approach. Other aircraft may well have tried warning us during approach. Error linked to unfamiliarity with audio panel of this plane (not model) and assumption of minimal traffic at N94 as well as failure to see white plane at end of runway blending with what we may have assumed to be a threshold.

Original NASA ASRS Text

Title: A C152 HAD AN NMAC WITH A DEPARTING C152 ON LNDG AT N94.

Narrative: WAS ON FINAL/SHORT FINAL AS ACFT DEPARTED HEAD-ON. ONLY NOTICED ACFT AFTER IT ROTATED. STUDENT AND I HAD ENTERED PATTERN ON 45 DEG OFF OF VOR 'A' APCH AND MADE ALL APPROPRIATE RADIO CALLS. NO ATIS/AWOS AVAILABLE AT LNDG FIELD. CHOSE RWY MOST CLOSELY ALIGNED WITH THAT IN USE AT CLASS D 10 MI E. ARPT OF LNDG HAS LOW VOLUME OF TFC USUALLY. RADIO WAS QUIET EXCEPT FOR 1-2 CALLS. WINDSOCK SHOWED LIGHT XWIND FAVORING RWY WE CHOSE. ASSUMED RWY CLR. AFTER LNDG, NOTICED THAT THE COM SELECTION WAS ON SPEAKER INSTEAD OF PHONE AND THE VOLUME LOW ENOUGH THAT COULD ONLY BE HEARD ON THE INTERCOM. AUDIO SELECTION WAS INADVERTENTLY BUMPED DURING THE APCH. OTHER ACFT MAY WELL HAVE TRIED WARNING US DURING APCH. ERROR LINKED TO UNFAMILIARITY WITH AUDIO PANEL OF THIS PLANE (NOT MODEL) AND ASSUMPTION OF MINIMAL TFC AT N94 AS WELL AS FAILURE TO SEE WHITE PLANE AT END OF RWY BLENDING WITH WHAT WE MAY HAVE ASSUMED TO BE A THRESHOLD.
