The bellcrank bracket is part of the aircraft's control system, and defects in these bolt holes could affect the pilot's ability to control the aircraft safely."}},"importantCases":[],"_links":{"self":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection","history":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection/history","analysis":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection/analysis","conflicts":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection/conflicts","importantCases":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection/important-cases","documents":"/api/acts/ad-mu-2-9-trim-aileron-bellcrank-bracket-bolt-holes-inspection/documents"}}
