What it does: This airworthiness directive requires owners/operators of specified Mitsubishi MU-2B aeroplanes to replace the series relay and modify the two‑battery electrical system before an Australian Certificate of Airworthiness is issued. It implements the manufacturer's bulletin (Mitsubishi SB 156) and the Japan Civil Aviation Bureau AD to address possible excessive arcing in the series relay that could damage the aircraft.
