This prevents items—like charts, pens, or debris—from falling through the gap and potentially interfering with flight controls or causing other safety hazards.\n\n**Who it affects:** Anyone who owns or operates a Gulfstream (formerly Grumman American/American Aviation) AA-5 series aeroplane, regardless of the specific model variant.\n\n**When compliance was required:** Within 100 hours of flight time after 31 December 1978 (meaning this directive is now long-standing and should already be complied with for any aircraft still in operation)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aa-5-21-glove-box-modification","history":"/api/acts/ad-aa-5-21-glove-box-modification/history","analysis":"/api/acts/ad-aa-5-21-glove-box-modification/analysis","conflicts":"/api/acts/ad-aa-5-21-glove-box-modification/conflicts","importantCases":"/api/acts/ad-aa-5-21-glove-box-modification/important-cases","documents":"/api/acts/ad-aa-5-21-glove-box-modification/documents"}}
