Plain English Summary

2/10 complexity

This AD requires owners/operators of Cessna 188 “Agwagon” aircraft to perform a specific exhaust leak test (per Cessna Service Letter SE73-22) at each Maintenance Release to detect fatigue cracks that can leak carbon monoxide into the cockpit. Turbocharged models without cabin heaters are exempt; turbocharged models with heaters need only the heater-shroud inspection. It’s a targeted safety check to catch invisible CO leaks that can incapacitate or kill.

Amdt 1

Exhaust System 11/86

Applicability: All models with the exception of turbocharged aircraft which do not have a cabin heater fitted.

Requirement: Inspect the exhaust system for leaks, using the technique detailed in Cessna SL SE73-22.

Note: Turbocharged aircraft fitted with a cabin heater need only have the heater shroud area inspected for leaks in accordance with the Requirement document.

Compliance: At each issue of a new Maintenance Release.

Background: Some instances of carbon monoxide contamination of the cockpit have been attributed to exhaust leakage from fatigue cracks. This leak testing supplements the visual inspections currently called for by the Maintenance Manual. This Directive has been amended to remove from compliance turbocharged aircraft which do not have a cabin heater fitted.
