A BHT222 struck the landing pad surface with the tail rotor during loss of control at lift off.

Narrative

After conducting a successful 'hot' deplaning on an elevated landing pad; I completed the Before Takeoff Checks and lifted off again. The takeoff was not smoothly coordinated and the tail rotor made contact with the pad deck. Weather at the time was clear skies with a slight tailwind of five knots. The aircraft was within CG limits and the parking brake was set. Night Vision Goggles were in use. During the takeoff sequence I had not compensated enough for the aft CG shift of the lighter gross weight and the aircraft moved forward immediately after lifting.It was while compensating for this movement that I felt the tail skid make contact with the landing pad. I transitioned to forward flight and made an uneventful landing later for fuel. There were no indications or symptoms during the flight of tail rotor damage. After shutdown; I immediately inspected the tail skid which showed fresh paint scrapings that confirmed it had made contact with the hospital pad. I then inspected the tail rotor blades and discovered damage to both blade tips. I immediately called the company and informed them of the incident.
