Alpine Aerotech, July 28, 2021 - Belowna, BC - ALPINE AEROTECH, an international leader in helicopter maintenance and product development announced that Transport Canada Civil Aviation (TCCA) Supplemental Type Certificate (STC) for the J301A-001 (STC number SH21-8) is applicable to the Bell aircraft series 412/212/205.
The J301 is a drop-in replacement for the Andrea A301 Series and the NAT N301A series audio panels allowing for an additional 2 TX/RX positions for a total of 8.
The J301 has the flexibility to work with several different ICS Tie line levels simplifying its interface with existing audio systems.
The STC can be implemented on an ‘as-needed’ basis. Therefore, any quantity of panels within the helicopters audio system can be upgraded, operators don’t have to implement them all of them at once.
About Alpine Aerotech LP: Alpine Aerotech LP provides comprehensive maintenance support for leading helicopter makes and models worldwide, operating with airworthiness certifications including Transport Canada, European Aviation Safety Agency, National Civil Aviation Agency of Brazil, Civil Aviation Authority of Egypt, Civil Aviation Authority of Papua New Guinea and Civil Aviation Authority of the Cayman Islands.

J301A-001 audio controller
The J301A-001 audio controller by Jupiter Avionics is a compact, lightweight unit that is compatible with the current industry standard interconnect. The unit will support one low impedance headset (5 ohm mic and 8 ohm phones) or one high impedance headset (150 ohm amplified dynamic mic and 150 ohm phones). By using a Windows® based application (ProCS™), configuration settings may be changed via a 3.5mm jack on the front panel. Field replaceable illuminated legends allow one version of the controller for many different mission configurations
