Nearly 40 years later, the Civil Aviation Safety Authority (CASA) has determined this requirement is no longer necessary. This cancellation removes the compliance obligation entirely, simplifying maintenance requirements for these older aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled","history":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled/history","analysis":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-25-23-fuel-tank-placard-modification-cancelled/documents"}}
