DO-227A Thermal runaway compliance with enhanced operational performance
SARASOTA, Fla., April 2, 2019 – Dukane Seacom (a HEICO Company, NYSE: HEI, HEI.A) received FAA TSO-126b for the DK-406-AF Emergency Locator Transmitter (ELT).
Dukane Seacom’s new AeroELT™ DK-406-AF is an integrated ELT solution that was designed and tested to the current and future requirements for worldwide ELT operations. With focus on high reliability, the DK-406-AF provides improvements in automatic triggering, meeting DO-227A thermal runaway containment requirements.
The DK-406-AF uses multi-axis MEMS technology to automatically detect impact, improving trigger reliability over traditional “G-Switch” triggers. A self-contained worldwide GNSS receiver further enhances the ability of search and rescue to quickly locate an aircraft in distress.
Significant focus was taken to address thermal runaway management during the design phase of the DK-406-AF ELT. The efficiently designed aluminum housing minimizes weight while meeting DO-227A for containment of a lithium battery thermal runaway event. The unit’s small footprint allows for flexible installation options for fixed wing and rotorcraft platforms.
“We are pleased to achieve these TSO certifications. The DK-406-AF brings additional operational and safety capabilities over existing ELT devices to benefit operators and search and rescue personnel,” said Jeff Densmore, Engineering Director for Dukane Seacom.
The DK-406-AF is Dukane’s newest emergency location product. With over 40 years of industry experience, Dukane Seacom has the largest install base of underwater locator beacons (commercial, military, and business jets) with over 100,000 ULB installed on aircraft. This unmatched reliability and expertise are what airlines/operators put their trust in when purchasing Dukane Seacom products.
