Plain English Summary

2/10 complexity

What this requires This directive orders a mandatory safety inspection for specific Cessna twin-engine aircraft (models 411, 411A, and 421) that have propeller de-icing systems fitted with McCauley “K” series (or later) propellers.

Who must comply Owners and operators of the affected aircraft models equipped with the specified de-icing systems.

What must be done An inspection of the propeller de-ice bolts must be carried out following the procedures in Cessna Service Letter ME69-37.

When it must be done

Within 10 hours of flight time after 16 February 1970; and
Every time the propeller, spinner bulkhead, or de-icing slip ring is removed and reinstalled or replaced.

Why it matters This ensures the propeller de-icing system—which prevents ice buildup on the propeller blades during flight in freezing conditions—remains mechanically secure and operational.
