It mandates a one-time inspection of the elevator control system.\n\n**Who it affects:** Owners and operators of all Piper PA-25 model aircraft.\n\n**What must be done:** Inspect the rear turnbuckles (adjustable metal tensioning devices) on the elevator control cables. The inspector must verify that these turnbuckles have enough clearance and can move freely without snagging on the elevator bungee links (rubber shock-absorbing connectors that dampen control movements).\n\n**Why it matters:** If a turnbuckle catches or binds against a bungee link, it could restrict or jam the elevator (the flap on the tail that controls the plane's pitch). This creates a risk of losing control of the aircraft's nose-up or nose-down attitude."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection","history":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection/history","analysis":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection/analysis","conflicts":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection/conflicts","importantCases":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection/important-cases","documents":"/api/acts/ad-pa-25-24-elevator-control-cable-rear-turnbuckles-inspection/documents"}}
