AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators must install a placard and amend the AFM within 30 days of the effective date to restrict mixture control use. The affected mixture control cables must be replaced during the next scheduled 50 flight hour check or the next 100 flight hour or annual check, whichever occurs first. After replacement, the placard and AFM amendment can be removed.
Summary
EASA Airworthiness Directive 2020-0147 is an airworthiness directive addressing mixture control cable issues on CEAPR DR400 aeroplanes, specifically models DR 400/120, DR 400/140 B, DR 400/180, and DR 400/180 R with certain serial numbers. It targets mixture control cables with Part Number 57.18.52.020 that may have uncripped cable sheaths, potentially causing loss of mixture control and engine shutdown. The directive mandates operational restrictions and replacement of affected parts to ensure continued airworthiness.
What changed
This new directive introduces an operational restriction on the use of the mixture control by requiring installation of a placard and amendment of the Aircraft Flight Manual. It also requires replacement of the affected mixture control cables within specified flight hour limits. Once replaced, the operational restrictions and placard can be removed.
Why it matters
This directive is critical for aviation professionals to prevent engine in-flight shutdowns caused by faulty mixture control cables, which could lead to forced landings and potential injuries. Operators and maintenance teams must comply to maintain aircraft safety and regulatory compliance. It ensures that affected aircraft are safely operated until the defective parts are replaced.
