These are legally binding orders issued under aviation safety laws.\n\n**Who it affects:** Owners and operators of Cessna 310R aircraft with serial numbers 310R0001 through 310R0816 (early production models).\n\n**What must be done:** The nose wheel well (the compartment where the front landing gear retracts) must be modified according to Cessna Service Letter SL ME77-12. This work had to be completed within 100 hours of flight time after 31 July 1977.\n\n**Why it matters:** ADs are not optional maintenance suggestions. An aircraft that hasn't complied with an applicable AD is legally unairworthy and cannot be flown. This directive addresses a specific structural or mechanical issue in the nose gear assembly that could compromise safety."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification","history":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification/history","analysis":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification/analysis","conflicts":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification/conflicts","importantCases":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification/important-cases","documents":"/api/acts/ad-cessna-310-47-nose-wheel-well-modification/documents"}}
