We propose to supersede Airworthiness Directive (AD) 2016-13- 16, which applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD 2016-13-16 requires an inspection or records check to determine if affected horizontal stabilizers are installed, related investigative actions, and, for affected horizontal stabilizers, repetitive inspections for any crack of the horizontal stabilizer rear spar upper chord, and corrective action if necessary. Since we issued AD 2016-13-16, we have determined that clarification of inspection areas and serial number information of the horizontal stabilizer is necessary. Therefore, this proposed AD would retain the requirements of AD 2016-13-16, with revised service information that clarifies the inspection areas and serial number information of the horizontal stabilizer. We are proposing this AD to address the unsafe condition on these products.
