Recommendations aren’t mandatory. Introduction This Special Airworthiness Information Bulletin advises you, owners and operators of DORNIER model 228 series airplanes, of issuance of maintenance materials related to Airworthiness Directive (AD) 2001-21-01. Background We issued AD 2001-21-01 on October 19, 2001, requiring the implementation of the provisions of DORNIER Service Bulletin SB-228-234 and repairs, if structural cracks were found as a result of the service bulletin inspections. DORNIER has now issued relevant service information in the form of maintenance manual revisions. Recommendations We won’t supersede AD 2001-21-01 until DORNIER issues service information requiring terminating action. The Small Airplane Directorate has approved the service information as an alternate method of compliance (AMOC) to DORNIER SB SB-228-234. We have attached a copy of the AMOC approval and Germany’s AD 2001-045/2 for your use. For Further Information Contact Karl M.

Standards Office, ACE-110 Reply to Karl Schletzbaum Attn. of: 816-329-4146 To: Docket 2001-CE-19-AD The Small Airplane Directorate issued Airworthiness Directive (AD) 2001-21-01 on October 9, 2001. This AD applied to Dornier Luffahrt GmbH (Dornier) models 228-100, 228-101, 228- 200, 228-201, 228-202 and 228-212 airplanes. The manufacturer subsequently issued maintenance manual temporary revisions numbers TR 55-6 and TR 05-88, dated April 22, 2003, which gave more descriptive instructions for the mandated inspection. The aviation authority of Germany, the Luftfahrt-Bundesamt revised its AD 2001-045 to revision 2001-045/2 (attached) to include this service information. Utilization of the maintenance materials, (attached) per the instructions of the German AD is approved as an AMOC for AD 2001-21-01. However, the provisions of AD 2001-21-01 that require the repair or replacement of affected structure, rather the continuing inspection, remain in force, as do the reporting requirements. Only the reference service information had changed. David R.
