What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On 10/08/2008, at around 2110 local time, the Gulfstream (g-iv) was observed on video camera taxiing towards the helicopters parked adjacent to taxiway h. on video you see the g-iv slowing down and changing course to the right avoiding what appears to be helicopter rotorblades. The visibility was diminished due to heavy rain. The left wing of the g-iv appears from the video to be over the taxiway at all times. During the investigation we were unable to determine if the helicopter rotorblades extended into the taxiway environment. The morning following the departure of the g-iv damage was discovered to the main rotor blades and rotor mask of the two helicopters. From the video it appears the g-iv possibly struck the rotor blades of two helicopters with its left wing tip as it taxied passed, on its way to runway 7. There was no damage to the g-iv.
