Advanced Torque Products (ATP) has a new custom tooling kit for the Airbus Helicopters EC145. The company said the product improves the torquing method of the mast nut.

According to ATP, the ATP760 tooling drastically reduces application time, increases accuracy to within 1%, takes away operator fatigue from holding the tool in place and increases overall operator safety.


“The purpose in developing this alternate tooling was to address current complexities,” ATP said. “Some of the issues maintenance professionals were facing was working with heavy tooling upside-down and having limited visibility through the reaction stand, which have proven to be a significant challenge working on the EC145. Without an appropriate mechanism in place to lock the tool in position from underneath, stability and alignment has been lost and accuracy put at risk.”

Airbus maintenance technicians from the manufacturer’s training facility worked with ATP to develop the new tooling.

All ATP Digital Torque Multipliers are 100% mechanical, the company said, utilizing stacked planetary gear systems. They can operate accurately in harsh environments, including the polar ice caps of the Antarctic and the Sahara desert.
