Plain English Summary

2/10 complexity

What this is: A mandatory safety notice (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority.

Who it affects: Owners and operators of Cessna Model 404 aircraft with serial numbers 404-0001 through 404-0133.

What you must do: Identify the hydraulic pump outlet pressure line following the instructions in Cessna Service Letter ME78-12. This means applying specific markings or labels so mechanics can tell this high-pressure hose apart from other hydraulic lines during maintenance.

When: Complete this work within 100 hours of flight time after 31 July 1978.

Why it matters: Clear identification prevents maintenance crews from accidentally disconnecting or confusing critical hydraulic lines, which could lead to loss of hydraulic pressure and control issues during flight.
