Aerospace Turbine Rotables, Inc. Announces Repair Capability for Underwater Acoustic Beacons

Wichita, KS and Addison, TX, July 25, 2025 – Aerospace Turbine Rotables, Inc., (“AeTR”), a subsidiary of First Aviation Services Inc., announced that they have expanded their extensive line of electrical capability to include the Dukane Models DK100, DK120, DK130, DK140 line of Underwater Acoustic Beacons (UABs) also known as Underwater Locator Beacons (ULBs) or “Pingers”.

Dukane Seacom UABs are an industry standard with 100,000 installations in commercial, regional, and business aviation aircraft equipped with modern flight and data recorders.

Aerospace Turbine Rotables’ team of highly trained technicians will replace the battery and all related accessories in your Dukane UABs and perform the rigorous testing required to ensure that your aircraft meets the requirements of FAA TSO-C121 for Underwater Locating Devices (Acoustic) (Self-Powered). This capability adds to Aerospace Turbine Rotables’ wide range of capabilities supporting aircraft batteries including standby power supplies.

Paul Bolton, President & COO of First Aviation, said “We have developed an economic, AOG rapid response solution to UABs to support our Corporate, Airline and Military customer bases.”

The company will be releasing a field kit for those MROs interested in repairing the UABs in the field.
