These guards stop the sun visor from accidentally bumping the magneto switches (the ignition controls that keep the engine running).\n\n**Who it affects**\n\nAnyone who owns, operates, or maintains a Partenavia P68 series aeroplane.\n\n**Why it matters**\n\nIf the sun visor knocks the ignition switches to the \"off\" position during flight, the engine could shut down unexpectedly. This simple physical modification prevents that potentially dangerous scenario.\n\n**When you must comply**\n\n*   **For new aircraft**: Install the guards before the Certificate of Airworthiness (C of A) is issued (for any aircraft certified after 28 February 1978).\n*   **For existing aircraft**: Install the guards within 100 hours of flight time after 28 February 1978."}},"importantCases":[],"_links":{"self":"/api/acts/ad-p68-7-ignition-switch-guard-modification","history":"/api/acts/ad-p68-7-ignition-switch-guard-modification/history","analysis":"/api/acts/ad-p68-7-ignition-switch-guard-modification/analysis","conflicts":"/api/acts/ad-p68-7-ignition-switch-guard-modification/conflicts","importantCases":"/api/acts/ad-p68-7-ignition-switch-guard-modification/important-cases","documents":"/api/acts/ad-p68-7-ignition-switch-guard-modification/documents"}}
