It requires aircraft owners or operators to perform specific maintenance or modifications to fix unsafe conditions in an aircraft type.\n\n**Who is affected**\nOwners and operators of **BAe 146** and **BAe 125** series aircraft (British Aerospace regional jets and business jets).\n\n**Why it matters**\nOnce revoked, operators no longer need to comply with the specific maintenance requirements outlined in AD/BAe 146/125. This typically happens when the safety issue has been resolved, the directive is obsolete, or it has been replaced by a new rule."}},"importantCases":[],"_links":{"self":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives","history":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives/history","analysis":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives/analysis","conflicts":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives/conflicts","importantCases":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives/important-cases","documents":"/api/acts/casa-adcx-013-12-revocation-of-airworthiness-directives/documents"}}
