DART announces certification of Ultrapaw

June 22, 2010  By Carey Fredericks

June 22, 2010, Oceanside, CA - DART Helicopter Services is pleased to announce that their affiliated partner, DART Aerospace Ltd., has received Transport Canada, FAA and EASA approval for their patent pending new design of Bearpaw, called the Ultrapaw, for the Bell 206L/L1/L3/L4/407 series of aircraft.

original DART Bearpaw, constructed of a UHMW polymer, addressed operator concerns
about durability and functionality and provided the most lightweight option at
the time for landing in soft or uneven terrain.

Constructed using innovative technology and ultra
lightweight material, the new Ultrapaw has a 40 per cent larger footprint for additional
support in soft terrain.  For the
same area, the material used in the Ultrapaw is at least 15 per cent lighter than any
comparable product currently available on the market.

savings has not come with a sacrifice in performance however.  The new lightweight Ultrapaw still
features a one-piece construction that ensures consistent and deliberate load
transfer.  The material resists
cracking, chipping and breaking and is flexible so it can deflect under
high-point contact loads and return to its original shape after take-off.
