Narrative:
Aircraft X was preparing to depart imperial airport. The sic made several radio calls on the unicom frequency advising traffic of the aircraft's intentions as it taxied into position for takeoff on runway 14 for a VFR departure. The PIC advanced the power levers to the takeoff position and noticed an aircraft displayed on the TCASII. Both the PIC and sic scanned the horizon looking for the lights of another aircraft, none were seen. The sic again made a radio call advising aircraft of their position, there was no response. The PIC then noticed a shadow of a helicopter on a right base on runway 32 and aborted the takeoff. The helicopter, a UH60 blackhawk initiated its approach to the runway without communicating its intentions on the unicom frequency and without displaying any landing or navigation lights. The UH60 came to a 100 ft hover approximately 900 ft in front of aircraft X. Once its approach was terminated the helicopter air-taxied to the ramp. The sic made repeated attempts to contact the helicopter on unicom and UHF guard with negative results.

Title: A C550 CREW, DEPARTING IPL, ABORTED THEIR TKOF WHEN A HELI WAS OBSERVED ON TCASII MAKING AN APCH TO THE OPPOSITE RWY!
Narrative: ACFT X WAS PREPARING TO DEPART IMPERIAL ARPT. THE SIC MADE SEVERAL RADIO CALLS ON THE UNICOM FREQ ADVISING TFC OF THE ACFT'S INTENTIONS AS IT TAXIED INTO POS FOR TKOF ON RWY 14 FOR A VFR DEP. THE PIC ADVANCED THE PWR LEVERS TO THE TKOF POS AND NOTICED AN ACFT DISPLAYED ON THE TCASII. BOTH THE PIC AND SIC SCANNED THE HORIZON LOOKING FOR THE LIGHTS OF ANOTHER ACFT, NONE WERE SEEN. THE SIC AGAIN MADE A RADIO CALL ADVISING ACFT OF THEIR POS, THERE WAS NO RESPONSE. THE PIC THEN NOTICED A SHADOW OF A HELI ON A R BASE ON RWY 32 AND ABORTED THE TKOF. THE HELI, A UH60 BLACKHAWK INITIATED ITS APCH TO THE RWY WITHOUT COMMUNICATING ITS INTENTIONS ON THE UNICOM FREQ AND WITHOUT DISPLAYING ANY LNDG OR NAV LIGHTS. THE UH60 CAME TO A 100 FT HOVER APPROX 900 FT IN FRONT OF ACFT X. ONCE ITS APCH WAS TERMINATED THE HELI AIR-TAXIED TO THE RAMP. THE SIC MADE REPEATED ATTEMPTS TO CONTACT THE HELI ON UNICOM AND UHF GUARD WITH NEGATIVE RESULTS.
