The work must be done according to one of three specific technical manuals:\n*   DH Modification DRO 77; **or**\n*   DH Technical News Sheet CT(A3) No. 79; **or**  \n*   ANO 105.1.14.14.5.11, Issue 2\n\n**When you must comply**\nImmediately (the directive uses the term \"**forthwith**\"). There is no grace period.\n\n**Why this matters**\nHand brakes are critical safety equipment that prevent aircraft from rolling when parked. This directive ensures every DHA-3 Drover meets the same safety standard to prevent ground accidents and injuries."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dha-3-10-hand-brake-installation-modification","history":"/api/acts/ad-dha-3-10-hand-brake-installation-modification/history","analysis":"/api/acts/ad-dha-3-10-hand-brake-installation-modification/analysis","conflicts":"/api/acts/ad-dha-3-10-hand-brake-installation-modification/conflicts","importantCases":"/api/acts/ad-dha-3-10-hand-brake-installation-modification/important-cases","documents":"/api/acts/ad-dha-3-10-hand-brake-installation-modification/documents"}}
