Think of it as a \"recall notice\" for aircraft, but legally binding.\n\n**What it does:** It requires owners/operators of specific Cessna 560 (Citation V) business jets to modify the **thrust reverser throttle load limiter** — a safety device on the engine controls. The modification must follow Cessna Service Bulletin 560-78-02.\n\n**Why it matters:** A malfunction was discovered where pilots trying to advance throttle levers during thrust reverser operation could accidentally trigger a spring-loaded limiter. If this device moved out of place, pilots would lose most of their ability to control engine power — a serious safety risk during landing or aborted takeoff.\n\n**Who must comply:** Owners of Cessna 560 aircraft with serial numbers ending in -071A, -092A, -109A, or ranging from -0001 to -0118.\n\n**Deadline:** Within 150 flight hours after 24 June 1993.\n\n**Key point:** This is not optional. Non-compliance grounds the aircraft (makes it illegal to fly)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter","history":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter/history","analysis":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter/analysis","conflicts":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter/conflicts","importantCases":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter/important-cases","documents":"/api/acts/ad-cessna-560-2-thrust-reverser-throttle-load-limiter/documents"}}
