MST 70B

ADS-B compliant transponder replacement for the MST 67A

Starting at $25,295 USD*

The MST 70B is an ADS-B Out transponder that enables you to comply with mandate to have ADS-B in your aircraft by January 1, 2020. It is a slide in replacement for your existing MST 67A transponders. The MST 70B broadcasts on 1090 mhz, and can be expanded to also receive ADS-B In using UAT, providing you with weather and traffic information.

LOWEST COST

At $55,900 for 2 transponders, it is one of the lowest cost solutions. The slide-in replacement units reuse your existing mounting hardware and wiring harness to reduce your installation costs up to 25% compared to switching vendors, as well as reducing any future repair costs.

LOWEST DOWNTIME

As a slide-in replacement for your MST 67A, no time is spent cutting your panel or mounting rack, replacing mounting trays or installing a new wiring harness. Your aircraft may be ADS-B compliant in less than 20 hours of service compared to 80 hours for alternative vendors’ solutions.

EASY TO MAINTAIN

For an optional additional flat fee, the Honeywell Avionics Protection Plan offers you an extended warranty that covers all repairs – in and out of warranty. And, with our SPEX exchange program, your downtime in case of repairs can be as low as one day.
