AD 2001-21-01 Amendment 39-12471

This amendment adopts a new airworthiness directive (AD) that applies to certain Dornier Luftfahrt GmbH (Dornier) Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes. This AD requires you to repetitively inspect the horizontal stabilizer skin and ribs for damage and cracks and repair any damaged skin or cracked ribs. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to detect and correct damage and fatigue cracks in the horizontal stabilizer skin and ribs. This condition could cause in-flight separation of the horizontal stabilizer skin with consequent loss of control of the airplane.
