Airworthiness Directives; Short Brothers Model SD3-60 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Short Brothers Model SD3-60 series airplanes, that requires a one-time inspection to detect discrepancies of certain diode mounting assemblies on specified electrical panels; follow-on actions; and repair or replacement with serviceable components, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent overheating and possible failure of certain electrical diodes, which could result in loss of electrical service to one or more airplane electrical circuits.
