Narrative:

Aircraft #1 was cruising at 5500 ft conducting flight training. Both aircraft were on a head-on collision course at same altitude. Instructor and student in aircraft #1 were discussing a training situation with reference to (focusing on) the instruments. Other aircraft was noticed with very little time to react. An immediate dive was made. The 2 aircraft would have collided if evasive (immediate and substantial) action was not taken. Flight training activities can have a tendency to draw the eyes inside the cockpit and I must make more of an effort in the future to keep my eyes outside.

Narrative: ACFT #1 WAS CRUISING AT 5500 FT CONDUCTING FLT TRAINING. BOTH ACFT WERE ON A HEAD-ON COLLISION COURSE AT SAME ALT. INSTRUCTOR AND STUDENT IN ACFT #1 WERE DISCUSSING A TRAINING SIT WITH REF TO (FOCUSING ON) THE INSTS. OTHER ACFT WAS NOTICED WITH VERY LITTLE TIME TO REACT. AN IMMEDIATE DIVE WAS MADE. THE 2 ACFT WOULD HAVE COLLIDED IF EVASIVE (IMMEDIATE AND SUBSTANTIAL) ACTION WAS NOT TAKEN.
