It applies to specific Piper PA-22 aircraft (Tri-Pacer and Colt models with serial numbers 22-1 through 22-348).\n\n**What it does:**\n- Requires owners/operators to insulate the battery terminals on these aircraft\n- Cites two technical documents that provide the proper procedure: Piper Service Bulletin No. 118 and FAA Airworthiness Directive 51-23-3\n\n**Who it affects:**\n- Owners and operators of Piper PA-22 aircraft with serial numbers in the specified range\n- Maintenance organisations servicing these aircraft\n\n**Why it matters:**\nBattery terminal insulation prevents electrical shorts, sparks, and potential fires. This is a safety-critical requirement that must be complied with \"forthwith\" (immediately). Failure to comply makes the aircraft unairworthy and illegal to fly.\n\n**Key details:**\n- **Compliance deadline:** Forthwith (meaning immediately, without delay)\n- **Status:** This is an active mandatory requirement (indicated by \"NK\" - Not Known/Cancelled, meaning it remains in force)\n- **Legal basis:** Civil Aviation Regulations 1988, Part 39"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-22-2-battery-terminal-insulation","history":"/api/acts/ad-pa-22-2-battery-terminal-insulation/history","analysis":"/api/acts/ad-pa-22-2-battery-terminal-insulation/analysis","conflicts":"/api/acts/ad-pa-22-2-battery-terminal-insulation/conflicts","importantCases":"/api/acts/ad-pa-22-2-battery-terminal-insulation/important-cases","documents":"/api/acts/ad-pa-22-2-battery-terminal-insulation/documents"}}
