| 2012-6628 | Airworthiness Directives; The Boeing Company Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This proposed AD was prompted by reports of incorrectly installed bolts common to the rear spar termination fitting on the horizontal stabilizer. This proposed AD would require inspecting for a serial number that starts with the letters "SAIC" on the left- and right-side horizontal stabilizer identification plate; a detailed inspection for correct bolt protrusion and chamfer of the termination fitting bolts of the horizontal stabilizer rear spar, if necessary; inspecting to determine if certain bolts are installed, if necessary, and related investigative and corrective actions if necessary. This proposed AD would also require repetitive inspections for cracking of the termination fitting at certain bolt locations, and repair if necessary. We are proposing this AD to prevent loss of structural integrity of the horizontal stabilizer attachment and loss of control of the airplane. | 2012-03-20 | 2012 | 3 | https://www.federalregister.gov/documents/2012/03/20/2012-6628/airworthiness-directives-the-boeing-company-airplanes | https://www.govinfo.gov/content/pkg/FR-2012-03-20/pdf/2012-6628.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes.
