Plain English Summary

1/10 complexity

This directive mandates safety modifications to specific aircraft to prevent dangerous engine overspeed conditions.

Who it affects Owners and operators of SIAI Marchetti S205 and S208 series aircraft equipped with:

Lycoming IO-360-A1A engines, and
Hartzell HC-C2YK-1/7666A-2 propellers

What it requires

Install a placard (a physical warning label) in the cockpit displaying critical engine operating limitations
Modify the tachometer markings (the gauge showing engine speed/revolutions per minute) to clearly indicate safe operating ranges and limits

Why it matters These changes ensure pilots can immediately see the maximum safe engine speeds, preventing operation beyond design limits that could cause catastrophic engine failure. The technical specifications for the modifications are contained in the manufacturer's Service Bulletin No. 205B18A.
