It requires two specific safety modifications before the plane can be certified as airworthy:\n\n1. **No-smoking sign**: Install a placard in the cabin warning passengers that smoking is banned during take-off, landing, and whenever the pilot says so.\n\n2. **Static electricity safety**: Install metal bonding points at fuel caps and grounding points on the landing gear. These allow ground crews to connect wires during refueling to prevent dangerous static electricity sparks that could ignite fuel vapours.\n\nCompliance is mandatory **before** the aircraft receives its Certificate of Airworthiness (the official approval that allows it to fly legally)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification","history":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification/history","analysis":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification/analysis","conflicts":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification/conflicts","importantCases":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification/important-cases","documents":"/api/acts/ad-pa-28-53-pre-certification-requirements-modification/documents"}}
