Narrative:
After completing the after takeoff checklist, we heard a buzzing sound, then a vibration, followed by main transmission chip caution light illumination. Captain executed memory item checklist, 'land immediately.' captain commanded. 'Arm the floats,' then at the right time, he commanded blow the floats. Aircraft made a gentle landing on the water. There were no injuries or airframe damage. During the descent, I was transmitting on 121.5 'mayday' and broadcasting our position. Upon landing, I used our handheld cellular phone, and called 911. A police dispatcher answered and I described our location and situation. The dispatcher contacted the coast guard, approximately 10 mins later, they arrived alongside and we transferred to the coast guard boat. We then towed the aircraft to shore where it was recovered. The aircraft is an S-76B. The NTSB is investigating the accident. Good training and a little luck resulted in a happy ending!
