Sandel Avionics has received an FAA STC for its ST3400H HeliTAWS wire and terrain safety system on a Bell 412EP helicopter. This announcement supplements an agreement Sandel has with the FAA to designate Part 27 and Part 29 helicopters operating under Part 91 or Part 135 rules as candidates for Field Approval installation of the ST3400H HeliTAWS unit. This provides for simplified installation under the guidelines in FSAW 02-03A. The new STC SR02355LA is available on the Sandel Web site at no charge with the purchase of qualifying HeliTAWS equipment.
Sandel’s HeliTAWS is a 3-ATI wire and terrain safety system that incorporates the WireWatch wire-strike avoidance feature, a Sandel invention that protects helicopters from the threat of known wires, guy lines and transmission lines. HeliTAWS also includes Sandel’s TrueAlert technology to eliminate nuisance alerts. The system is completely automatic and does not require pilot management of the phase of flight.
