Ascent Aerospace sent us these photos of their redesigned helitank for a Bell 212, called the Ascent 50001C. The 360-gallon tank is made from carbon fiber and has a retractable snorkle and a system that maps the coordinates of all water drops. The system is certified to allow the transportation of passengers when the helitank is installed.
The company told us the tank is certified to the latest FAA FAR 27/29 STC requirements for helicopter safety and crash worthiness. It received Supplementary Type Certification (STC) from the Australian Civil Aviation Safety Authority (CASA) on June 19, 2013 and from Transport Canada on November 1, 2013. FAA STC certification will be underway in the near future.
