This proposed AD would require a general visual inspection to identify any existing repairs of the upper main sill outer chord of the left and right side main entry door number 1, as applicable; repetitive detailed inspections for cracks in the upper main sill of the door(s); and related investigative and corrective actions, if necessary. This proposed AD would also require repetitive inspections for airplanes on which a certain repair is done, and corrective actions if necessary. This proposed AD results from reports of cracks in the main entry door number 1 upper main sill outer chord, along the bend radius of the chord on several airplanes. We are proposing this AD to detect and correct such cracks, which could result in loss of structural integrity of the airplane.", "2009-09-28", 2009, 9, "https://www.federalregister.gov/documents/2009/09/28/E9-23294/airworthiness-directives-boeing-model-747-100-747-100b-747-100b-sud-747-200b-747-200c-747-200f", "https://www.govinfo.gov/content/pkg/FR-2009-09-28/pdf/E9-23294.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We propose to adopt a new airworthiness directive (AD) for all Boeing Model 747 airplanes.
