The listed owner of the helicopter is Challenger Management LLC located in West Palm Beach, Florida.
The Company also owns a Cessna 208, EMB-505, ERJ-190-100 ECJ, and a EMB 550,
One question that comes to mind is.....are they operating as a FAA Part 91 Corporate Flight Operation or are they operating the fleet as an FAA Part 135 Air Taxi Operation to offset the costs of the fleet?
The key here is the added requirements for training, etc....imposed on the operation by the FAR's if they are Part 135 over that required under Part 91.
The flight in question could be done under Part 91....and not Part 135.....which would pertain to Operational Control, Weathe Minimumsr, Instrument Approaches, and other procedures which Part 135 would require.
I have been unable to find any listing showing them to be a published Air Taxi Operator and thus assume they operate purely as a Corporate Flight Department.
Generally, the Insurance Company drives the training requirements more than the FAA in those cases.....that and what Management of the Operation decide is appropriate and affordable.
