It orders owners of specific Piper aircraft to fix a dangerous design flaw in how the battery is secured.\n\n**Who it affects**\nOwners and operators of Piper PA-32-301T (Cherokee Six) aircraft with serial numbers between 32-8024001 and 32-8424002.\n\n**What you must do**\nModify or replace the battery straps according to the manufacturer's instructions in **Piper Service Bulletin No 804**. This ensures the battery stays put during rough conditions.\n\n**When**\nComplete the work within **100 hours of flying time** after 31 July 1985, or at the **next scheduled maintenance inspection** after that date—whichever happens later.\n\n**Why it matters**\nThe manufacturer found that batteries can break loose from their boxes during severe turbulence or in a crash. A flying battery can start fires, damage equipment, or injure occupants."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-73-battery-strap-installation","history":"/api/acts/ad-pa-32-73-battery-strap-installation/history","analysis":"/api/acts/ad-pa-32-73-battery-strap-installation/analysis","conflicts":"/api/acts/ad-pa-32-73-battery-strap-installation/conflicts","importantCases":"/api/acts/ad-pa-32-73-battery-strap-installation/important-cases","documents":"/api/acts/ad-pa-32-73-battery-strap-installation/documents"}}
