Dual Cargo Hook Kit

Product Number: 200-448-00

Onboard Systems has developed a Human External Cargo (HEC) hook kit for the MD500 aircraft series. Built around a dual installation of our TALONĀ® LC Hydraulic Hook, this kit provides an STC-certified solution for a variety of CFR Part 133 external load missions, including HEC, high-value cargo transport, utility line work, short haul, and search & rescue.

NOTE: FAA certification pending for Human External Cargo (HEC) missions

Benefits

  • Complete Dual-Hook Solution:Comes with everything you'll need to upgrade your aircraft to a dual cargo hook system, including primary and secondary cargo hooks, attach point fittings, master and slave cylinders, external electrical release harnesses, and hardware.
  • STC Certified for HEC Missions:This cargo hook system meets the 14 CFR part 27 certification requirements for Human External Cargo (HEC).
  • Combined Dual Master Cylinder:User-friendly dual master cylinder combines the backup hydraulic release for both hooks along with the electrical release for the secondary hook into a single unit.
  • HEC Longline Options:Choose one of our HEC longlines, or use a longline approved by the local aviation authority.
  • NHEC Load Options:With the Y-rope attached to both cargo hooks, the dual cargo hook system load limit is 800 lb. (363 kg) for both HEC and non-HEC (NHEC) missions. When an NHEC load is attached to only the primary cargo hook, the load limit is 2,000 lb. (907 kg).
  • TALON® LC Hydraulic Hook:Our hydraulic hook greatly increases load security by using a hydraulically activated release mechanism instead of a traditional manual release cable.
 

Hardware Notes

  • Operation of this dual cargo hook system requires that an external mirror be installed to allow the pilot to monitor the cargo hooks.
  • Requires some fixed provisions from MD Helicopters; please refer to Owner's manual or contact us.
  • Transport of HEC requires the use of an Onboard Systems Y-rope (P/N 490-014-00, sold separately) attached to both the primary and secondary cargo hook.
  • A Personnel Carrying Device System (PCDS) harness, as well as equipment to allow direct communication among required crewmembers and external occupants, must be approved by the local aviation authority. These are not available from Onboard Systems.
