Dukane Seacom Receives TSO-C121b & TSO-C142b For DK290 Low-Lithium 90-Day Underwater Locator Beacon and Battery

Complete Thermal Runaway Compliance With Low-Lithium Battery

SARASOTA, Fla., October 2, 2019 – Dukane Seacom (a HEICO company, NYSE: HEI, HEI.A) received FAA TSO-C121b and TSO-C142b for the DK290 90-Day Underwater Locator Beacon and Low-Lithium Battery.

Dukane Seacom’s new DK290 underwater locator beacon (ULB) provides 90-days of operational life and uses lower lithium content batteries allowing for less restricted hazardous goods shipping processes.

The DK290 is fully compliant with the latest DO-227A Lithium Battery requirements and meets all non-rechargeable lithium battery special conditions requirements for installation on aircraft. The DK290 builds on Dukane Seacom’s industry leading ULB technology by providing common installation and maintenance processes as Dukane Seacom’s existing 90-day ULBs. This common design and maintenance approach will provide airlines and fleet maintenance organizations reliable performance and reduce shipping and handling costs with the new low-lithium technology batteries.

"We are pleased to achieve these TSO certifications. The DK290 builds on Seacom’s product legacy and simplifies shipping and handling processes with the lower lithium content," said Jeff Densmore, Engineering Director for Dukane Seacom.

With over 50 years of industry experience, Dukane Seacom has the largest installed base of underwater locator beacons (commercial, military, and business jets) with over 120,000 ULBs installed on aircraft. This unmatched reliability and expertise are what airlines/operators put their trust in when purchasing Dukane Seacom products.
