Plain English Summary

2/10 complexity

This is a mandatory safety instruction (called an Airworthiness Directive) for owners of specific American Champion aircraft.

What it requires: If you own an American Champion, Aeronca, or Bellanca aeroplane built before 28 April 1969, you must perform specific maintenance on the throttle arm and knob (the controls that manage engine power). The work must follow the manufacturer's instructions in "Champion Service Letter No. 94."

Who it affects: Owners and operators of all American Champion aircraft models manufactured before 28 April 1969.

When it had to be done: Within 100 hours of flight time after 31 March 1972 (this is a historical directive from 1972).

Why it matters: Airworthiness Directives are legally binding safety orders. They typically address design defects or unsafe conditions that could cause accidents. This specific directive likely addressed a mechanical issue with the throttle controls that could affect flight safety.
