Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires owners and operators of specific Beechcraft Bonanza aeroplanes (Models 35 and A35) to fix or modify their **trailing antenna** — a long wire antenna that trails behind the aircraft in flight. The work must follow specific instructions in Beechcraft Service Bulletins (official manufacturer repair guides).\n\n**Who it affects:** Anyone who owns, operates, or maintains a Beechcraft Model 35 or A35 Bonanza that has an **automatic reel trailing antenna** (a type that winds in and out automatically).\n\n**Why it matters:** Trailing antennas can fail in ways that damage the aircraft or cause safety hazards. This directive ensures these specific aircraft get inspected and repaired **immediately** (\"forthwith\") to prevent accidents.\n\n**Key details:**\n- **Compliance deadline:** Immediately — no grace period\n- **Source:** Based on a US Federal Aviation Administration (FAA) directive (AD 49-26-1)\n- **How to comply:** Follow Beechcraft Service Bulletin No. 13 (for Model 35) or No. 4 (for Model A35)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-35-4-trailing-antenna-rework","history":"/api/acts/ad-beech-35-4-trailing-antenna-rework/history","analysis":"/api/acts/ad-beech-35-4-trailing-antenna-rework/analysis","conflicts":"/api/acts/ad-beech-35-4-trailing-antenna-rework/conflicts","importantCases":"/api/acts/ad-beech-35-4-trailing-antenna-rework/important-cases","documents":"/api/acts/ad-beech-35-4-trailing-antenna-rework/documents"}}
