John Heinz

I think you are looking for this:

''Heinz and six other people were killed when a Bell 412 SP (An aircraft without wings that obtains its lift from the rotation of overhead blades) helicopter collided with the Senator's Piper Aerostar plane over a schoolyard in (Click link for more info and facts about Lower Merion Township, Pennsylvania) Lower Merion Township, Pennsylvania. All aboard the two aircraft and two children playing outside the school were killed. The helicopter had been dispatched to check out a problem Heinz's plane was having with its landing gear. While moving in for a closer look, the helicopter's rotor blades struck the bottom of the plane, causing both aircraft to lose control and crash.''

Thanks so much Greekman 🙂

I thought it was either a Piper or Gulfstream.
