Interesting to add regarding Airwolf Straps:

Bell Textron - Canada, 206B
Cracked Tension Torsion Strap Urethane Coating
SDR #: 20170808010
Subject:
During a routine 3 year calendar tension/torsion strap change, cracks were found in the urethane casing of the strap. This exposes the stainless steel wires to the elements.
Transport Canada Comments:
Cracks in the urethane protective coating of any tension/torsion strap could lead to internal corrosion of the straps. Visual inspection of the straps should be conducted whenever the opportunity is available to do so. The Australian Civil Aviation Authority has issued Airworthiness Bulletin 63-009 recommending inspection of the straps for cracks in the coating. Similarly, Bell Helicopter has issued Alert Service Bulletin 206-13-130 introducing a reduction to the life limit and removal of some part numbered straps. If cracks are found in the urethane coating of any manufactures tension/torsion straps please submit a Service Difficulty Report for each occurrence.
