Luftfahrt-Bundesamt (LBA) Airworthiness Directives D-2007-350 and D-2007-353 for the RUAG Aerospace GmbH Dornier 228 series aircraft.
Summary
The Luftfahrt-Bundesamt (LBA) Airworthiness Directives D-2007-350 and D-2007-353 address safety issues for the RUAG Aerospace GmbH Dornier 228 series aircraft. AD D-2007-350 concerns partial de-bonding of surface protection on rudders and elevators due to an unapproved paint stripping process. AD D-2007-353 deals with cracks in rudder control cable terminals caused by production errors in cables delivered after January 1, 2006.
What Changed
These new airworthiness directives introduce mandatory inspections and corrective actions for the Dornier 228 aircraft. AD D-2007-350 requires detailed visual inspections of rudder and elevator inner structures and repairs if corrosion or de-bonding is found. AD D-2007-353 mandates removal and return of affected rudder control cables and prohibits their installation, with replacement required by March 31, 2008.
Why It Matters
These directives are critical for maintaining the structural integrity and safe operation of Dornier 228 aircraft. Operators and maintenance organizations must address potential corrosion and manufacturing defects that could compromise flight safety. Compliance ensures continued airworthiness and adherence to national aviation authority requirements.
What To Do
Operators must perform detailed inspections of rudder and elevator surfaces within two months of the AD release and report any corrosion or de-bonding findings immediately. Affected rudder control cables identified by part number and batch must be removed and returned to RUAG Aerospace, with replacements installed no later than March 31, 2008. All repairs and actions must follow the referenced RUAG Service Bulletins SB-228-270 and SB-228-269.
