Plain English Summary

CASA has issued a mandatory Airworthiness Directive requiring owners/operators of Twin Commander 500/600/700 series aeroplanes (specified serials and any aircraft fitted with nose‑wheel steering) to modify the power brake valve system forthwith per Aero Commander Service Bulletin No. 48.

The immediate modification prevents power brake valve failures that can cause loss of braking or nose‑wheel steering control and potential runway excursions.
