A PA28 INSTRUCTOR AND STUDENT ON TKOF HAD A NEAR MISS WITH A BLACKHAWK HELI.

Narrative

PA28R-201 ON A TRAINING MISSION (1 INSTRUCTOR AND 1 STUDENT ON BOARD) WAS TAKING OFF FROM RWY XX AT XA15 (AWOS RPTED CALM WIND); AFTER MAKING APPROPRIATE CTAF CALLS WHILE TAXIING; HOLDING SHORT; AND LINING UP FOR TKOF ON RWY XX. AFTER ROTATION AND TKOF; BUT WITH THE LNDG GEAR STILL EXTENDED; MY STUDENT AND I SIMULTANEOUSLY SAW A BLACKHAWK HELI AT OUR ALT (LESS THAN 50 FT AGL); ABOUT TO CROSS OUR FLT PATH (ABOUT 500 FT AHEAD); XING THE RWY FROM R TO L (IE; S TO N). I TOOK THE CTLS; REDUCED THROTTLES TO IDLE; PITCHED DOWN TO PASS BENEATH THE HELI AND LANDED THE AIRPLANE ON THE REMAINING RWY. THE HELI APOLOGIZED ON THE CTAF. NEITHER MY STUDENT NOR I HAD HEARD ANY RADIO CALLS OF HIS INTENTION TO TAKE OFF. THE BLACKHAWK HELI HAD ARRIVED JUST A FEW MINS EARLIER AND HAD RPTED ON THE CTAF THAT HE WOULD BE DROPPING OFF A PAX. ON ARR HE HAD MADE CALLS ON THE CTAF ON EXTENDED BASE; BASE; AND SHORT FINAL TO THE HELI PAD. NO CALLS WERE MADE ON THE CTAF FOR HIS DEP. CLEARLY; HE HAD NOT BEEN LISTENING TO OUR CALLS EITHER.
