Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Short Brothers Model SD3-SHERPA, SD3-60 SHERPA, SD3- 30, and SD3-60 series airplanes, that requires a one-time detailed visual inspection of the emergency brake accumulator mounting structure for evidence of cracking; and corrective action, 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 failure of the mounting angle that supports the emergency brake system due to cracking, which could result in loss of the emergency brake system.
