Plain English Summary

2/10 complexity

What this does: This is a safety rule (called an Airworthiness Directive) that requires owners of specific Beechcraft aeroplanes to install a noise filter (capacitor) on their aircraft's navigation radio.

Who it affects: Owners of Beechcraft Model A23-24 aeroplanes with specific serial numbers only — MA-2, 3, 5, 9, 11, 24, 29, 31, 32, 33, 35, 44, 61, 64, 66, 69, 71, 72, 76, 77, 81, 83, 89, 90, 102, 104, 105, 107, 108, 109, 111, 115, 131 and 134.

What you must do: Attach an ADF (Automatic Direction Finder) Noise Suppressor Capacitor by following the instructions in Beechcraft Service Bulletin No. 66-65. The ADF is the radio navigation equipment that helps pilots determine their direction.

Why it matters: The capacitor suppresses electrical noise that could interfere with the aircraft's navigation system, preventing potential loss of directional guidance.

Compliance: The modification had to be completed before 1 September 1971.
