Before these planes can receive their **Certificate of Airworthiness** (the official approval allowing them to fly legally), they must undergo three specific safety modifications:\n\n*   **Fire safety signage:** Install a placard in the cabin clearly stating when smoking is prohibited.\n*   **Refueling safety:** Install proper electrical grounding points (called **bonding points**) at every fuel filling point and on the landing gear assemblies. This prevents dangerous sparks during refueling by ensuring static electricity safely dissipates into the ground.\n*   **Fuel hose protection:** Replace four specific flexible fuel hoses (located between the fuel pump, fuel filter, control unit, and distributor valve) with fire-resistant versions meeting the **FAA TSO C53B** safety standard, or cover them with approved fire-resistant sleeves.\n\nThese changes must be completed **before** the aircraft can be certified to fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-206-17-pre-certification-requirements","history":"/api/acts/ad-cessna-206-17-pre-certification-requirements/history","analysis":"/api/acts/ad-cessna-206-17-pre-certification-requirements/analysis","conflicts":"/api/acts/ad-cessna-206-17-pre-certification-requirements/conflicts","importantCases":"/api/acts/ad-cessna-206-17-pre-certification-requirements/important-cases","documents":"/api/acts/ad-cessna-206-17-pre-certification-requirements/documents"}}
