| 2014-12475 | Airworthiness Directives; The Boeing Company Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC-9-10, DC-9-20, and DC-9-30 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the improved (shot-peened) aft fuselage non-ventral pressure bulkhead tee is subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections for cracking of the improved (shot-peened) non-ventral aft pressure bulkhead tees, and replacement if necessary. We are proposing this AD to detect and correct fatigue cracking of the improved (shot- peened) non-ventral aft pressure bulkhead dome tees connecting the bulkhead web to the fuselage, which could result in reduced structural integrity and rapid decompression of the airplane. | 2014-05-29 | 2014 | 5 | https://www.federalregister.gov/documents/2014/05/29/2014-12475/airworthiness-directives-the-boeing-company-airplanes | https://www.govinfo.gov/content/pkg/FR-2014-05-29/pdf/2014-12475.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC-9-10, DC-9-20, and DC-9-30 series airplanes.
