Summary
EASA Airworthiness Directive 2018-0285 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all models and serial numbers of Pilatus PC-6 aeroplanes. It mandates compliance with updated airworthiness limitations and maintenance tasks as specified in the latest Pilatus PC-6 Aircraft Maintenance Manual and Airworthiness Limitations Section documents. This directive ensures continued airworthiness by enforcing mandatory maintenance and replacement of life-limited parts.
What changed
EASA Airworthiness Directive 2018-0285 supersedes the previous AD 2014-0181 and introduces new and/or more restrictive maintenance tasks and airworthiness limitations for Pilatus PC-6 aeroplanes. It requires operators to comply with the updated ALS and AMM documents issued in November 2018, which include reduced thresholds and intervals for certain maintenance tasks and component replacements.
Why it matters
This directive is critical for aviation professionals as it ensures the continued safety and airworthiness of Pilatus PC-6 aeroplanes by enforcing updated maintenance standards. Operators, maintenance organizations, and compliance teams must adhere to these requirements to avoid unsafe conditions and regulatory non-compliance. Failure to implement these updated tasks and limitations could lead to unsafe aircraft operation and potential regulatory penalties.
