Specifically, the \"mechanism cup assembly\" (part number 0109255-01) inside reel models 0109101-01, -03, -05, and -07 doesn't pull the belt back with enough force. This means your restraint might not tighten properly when you need it.\n\n**What must be done:** Aircraft owners must modify these reel assemblies following the manufacturer's instructions (Pacific Scientific Service Bulletin No. 0109101-25-01).\n\n**When:** Within 100 hours of flying time after 30 November 1983, or at the next scheduled maintenance check after that date—whichever happens later.\n\n**Why it matters:** Faulty retraction force could mean seatbelts don't secure occupants properly during turbulence or an accident, increasing injury risk."}},"importantCases":[],"_links":{"self":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification","history":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification/history","analysis":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification/analysis","conflicts":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification/conflicts","importantCases":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification/important-cases","documents":"/api/acts/ad-res-15-pacific-scientific-dual-tension-reel-assembly-p-nos-0109101-01-03-05-07-modification/documents"}}
