Superseded. A later AD replaced this one: AD 2001-08-09. Comply with the one in force.
Model 737-600, -700, -800, and -700C series airplanes, as listed in Boeing Alert Service Bulletin 737-55A1072, Revision 1, including Appendix A, dated January 11, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, -800, and -700C series airplanes. This action requires initial and repetitive inspections of the elevator tab assembly to detect any damage or discrepancy; and corrective actions, if necessary. This action is necessary to prevent excessive in-flight vibrations of the elevator tab, which could lead to loss of the elevator tab and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
