Plain English Summary

1/10 complexity

What this is An airworthiness directive (a mandatory safety rule) issued by the Civil Aviation Safety Authority targeting a specific model of aircraft radio equipment.

Who it affects Owners and operators of aircraft fitted with Bayside BEI-990 series VHF transceivers (specifically models BEI-990, BEI-990H, BEI-990E, and BEI-990P).

What it requires By 1 December 1974, owners had to choose one of two options:

Modify the radio to reduce unwanted signal interference (called "spurious emissions") to at least 40 decibels below the main transmission frequency; or
Retire the equipment completely (remove it from aircraft service).

Why it matters This rule prevents radio interference that could disrupt critical aircraft communications or navigation signals, ensuring safe operations by mandating either repair or removal of faulty equipment.
