Aircraft that never incorporated the original service bulletin are excluded.\n\n**What you must do:** Ensure the aircraft meets the standards set out in **Revision 1** of Cessna Service Bulletin MEB 88-3. This updates the original wiring modification to include additional necessary safety features.\n\n**When:** The work must be completed prior to the aircraft's next Maintenance Release (safety certificate) being issued after 31 December 1989.\n\n**Why it matters:** The original service bulletin was deemed insufficient to warrant a mandatory directive. This order ensures critical safety features in the revised bulletin are actually incorporated into modified aircraft to prevent potential fuel system failures."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification","history":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification/history","analysis":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification/analysis","conflicts":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification/conflicts","importantCases":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification/important-cases","documents":"/api/acts/ad-cessna-303-10-auxiliary-fuel-pump-wiring-modification/documents"}}
