Plain English Summary

1/10 complexity

What this rule does:

This is a safety directive for Cessna 185 aircraft used in agricultural operations (such as crop dusting). It mandates regular inspection of a specific mechanical component — the tailwheel steering bellcrank (part number 0712309-1) — located in the rear fuselage.

What must be done:

Inspect this component for "elongated pin holes" (worn, stretched holes where connecting pins sit, indicating metal fatigue)
Replace the bellcrank immediately if wear is detected
How often: Every 100 hours of flight time ("time in service")

Why it matters: Worn steering bellcranks can fail, causing pilots to lose directional control of the aircraft's tailwheel during taxiing, takeoff, or landing. This poses particular risks for agricultural aircraft operating from rough, unimproved airstrips.

Who it affects: Owners, operators, and maintenance engineers responsible for all Cessna 185 models certified in the agricultural category.
