Specifically, they must install a multi-bolt attachment system for the stabilising strut, following the technical instructions in **Scottish Aviation Modification No. C311**.\n\n**Who must comply:**\nAll models of the Twin Pioneer aircraft.\n\n**When:**\nImmediately (the term *\"forthwith\"* means without delay — you cannot defer this work).\n\n**Why it matters:**\nThis directive addresses a specific safety defect or structural weakness in the original strut attachment design. Non-compliance is illegal and could lead to structural failure in flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut","history":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut/history","analysis":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut/analysis","conflicts":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut/conflicts","importantCases":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut/important-cases","documents":"/api/acts/ad-sa-tp-3-lift-strut-incorporating-multi-bolt-attachment-for-stabilising-strut/documents"}}
