Plain English Summary

3/10 complexity

This Airworthiness Directive requires aircraft operators and owners with certain Honeywell MST 67A Mode S transponders (specified part numbers and serial-number ranges) to perform corrective actions ordered by CASA. It responds to test results showing these transponders may fail to reply to Mode S “all call” (UF11) interrogations, which could prevent air‑traffic radar from detecting the aircraft, and mandates fixes within the compliance times set in the directive.
