Plain English Summary

1/10 complexity

What this is: An Airworthiness Directive — a mandatory safety notice issued by the Civil Aviation Safety Authority (CASA).

Who it affects: Owners and operators of Beechcraft Model 65-90 King Air aeroplanes with serial numbers earlier than LJ-22.

What it requires: You must modify the engine oil pressure gauges on these aircraft immediately (the directive uses the word "forthwith," which means without delay). The specific technical instructions for the modification are contained in a manufacturer document called Beechcraft Service Bulletin 65-6.

Why it matters: Faulty oil pressure gauges can fail to warn pilots of engine problems, potentially leading to engine damage or in-flight failure. This directive ensures pilots receive accurate oil pressure readings.
