Narrative:

Aircraft involved: small aircraft and small aircraft helicopter. Small aircraft was practicing touch-and-go's on runway 5 (2300 ft paved) at agc. Helicopter was cleared for departure north, but stay clear of runway 5 and use caution. While small aircraft was on takeoff roll the helicopter was observed approaching at right angles and approximately 75 ft AGL. Small aircraft could not abort so held aircraft on runway until after rotation speed to allow room for helicopter. ATC says they are correct (regarding separation at a controled airport), at least according to the law. The helicopter pilot says that he's ok because ATC didn't tell him to remain east of the extended centerline! Common sense dictates otherwise. What if the helicopter would have been an light transport or small transport? (Wake turbulence would have creamed me.)

Original NASA ASRS Text

Title: SMA ON TKOF HAS NMAC WITH HELI ALSO CLRED FOR TKOF.

Narrative: ACFT INVOLVED: SMA AND SMA HELI. SMA WAS PRACTICING TOUCH-AND-GO'S ON RWY 5 (2300 FT PAVED) AT AGC. HELI WAS CLRED FOR DEP N, BUT STAY CLR OF RWY 5 AND USE CAUTION. WHILE SMA WAS ON TKOF ROLL THE HELI WAS OBSERVED APCHING AT R ANGLES AND APPROX 75 FT AGL. SMA COULD NOT ABORT SO HELD ACFT ON RWY UNTIL AFTER ROTATION SPD TO ALLOW ROOM FOR HELI. ATC SAYS THEY ARE CORRECT (REGARDING SEPARATION AT A CTLED ARPT), AT LEAST ACCORDING TO THE LAW. THE HELI PLT SAYS THAT HE'S OK BECAUSE ATC DIDN'T TELL HIM TO REMAIN E OF THE EXTENDED CTRLINE! COMMON SENSE DICTATES OTHERWISE. WHAT IF THE HELI WOULD HAVE BEEN AN LTT OR SMT? (WAKE TURB WOULD HAVE CREAMED ME.)
