Narrative:

A VFR helicopter crew was checking all mission equipment for proper operation before overseas deployment. Pilot flying was in the starboard seat; pilot not flying in port seat with head down energizing and programming gear. Were cleared to cross below the north to south ILS approach path from west to east and 'report traffic on final in sight'. Pilot flying asked pilot not flying; 'you got the aircraft'? Pilot not flying; lacking situational awareness; 'uhh; yeah' and took over flight controls. A cessna 412 broke out of the overcast; could not see helicopter. Helicopter pilot took no evasive action. Cessna cleared top of helicopter by just a few feet. Starboard-seat pilot remarked; 'wow that was close.' port-seat pilot responded; 'what was close?' I was in the port seat. I never saw the cessna. I thought the starboard-seat pilot wanted me to take control for some reason. He thought I saw the conflicting aircraft and would take evasive action. Lesson learned: 'I have control' and 'you have control' are magic words. Never say 'you got the aircraft?'

Narrative: A VFR helicopter crew was checking all mission equipment for proper operation before overseas deployment. Pilot flying was in the starboard seat; Pilot not flying in port seat with head down energizing and programming gear. Were cleared to cross below the N to S ILS approach path from W to E and 'report traffic on final in sight'. Pilot flying asked pilot not flying; 'You got the aircraft'? Pilot not flying; lacking situational awareness; 'UHH; yeah' and took over flight controls. A Cessna 412 broke out of the overcast; could not see helicopter. Helicopter pilot took no evasive action. Cessna cleared top of helicopter by just a few feet. Starboard-seat pilot remarked; 'Wow that was close.' Port-seat pilot responded; 'What was close?' I was in the port seat. I never saw the Cessna.
