Plain English Summary

1/10 complexity

This is a safety order (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority. It requires owners of three specific vintage C.A.C. Ceres aircraft (serial numbers 5, 6, and 13) to modify a safety structure called the "turnover truss" — a metal frame designed to protect the pilot if the plane flips over on landing.

Why it matters: After a fatal accident where this truss collapsed during an overturn, the authority mandated a structural fix detailed in Ceres Service Bulletin No. 45. Owners must have this modification completed by 21 January 1980.

Who is affected: Only the operators of the three specific aircraft listed (registration marks VH-CDO, VH-CEG, and VH-SSF). If you already modified your aircraft under an earlier related directive (AD/CA-28/7), you don't need to do it again.
