Cirrus SR22 — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) of Australia, specifically addressing safety concerns related to the Cirrus Design SR20 and SR22 series aeroplanes. The directive outlines necessary actions to correct identified unsafe conditions, particularly focusing on the exhaust heat exchanger. The AD mandates inspections and potential replacements of components to prevent hazardous conditions such as carbon monoxide leaks into the cabin, which could incapacitate pilots. Compliance with the directive is crucial for maintaining airworthiness and ensuring pilot safety.

• Initial inspection of the exhaust system must be done within 25 hours TIS or 3 months after the AD effective date.
• Repetitive inspections should occur every 100 hours TIS thereafter.
• If defects are found or exhaust odour is detected, replace the heat exchanger weldment and shroud before further flight.
• This AD is effective from 28 August 2008.
• The directive applies to Cirrus SR20 serial numbers 1005 through 1815 and the SR22 series.
