The four-seat Robinson R-44 struck the canopy at the fueling station area of the airport and exploded shortly after 11 p.m. Sunday, according to a preliminary report from the Federal Aviation Administration.
FAA spokesman Ian Gregor said a National Transportation Safety Board investigator at the crash scene said the helicopter's rotor blades struck the canopy that sits over the fuel pumps.
