Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 707-300, 707-300B, and 707-300C series airplanes; and certain Model 727C, 727-100C, and 727-200F series airplanes. This AD was prompted by a report indicating that a cam latch on the main cargo door (MCD) broke during flight. This AD requires various inspections and related investigative and corrective actions, if necessary. We are issuing this AD to address the unsafe condition on these products.
