    The FAA has issued an airworthiness directive (AD) requiring earlier and more frequent fuselage inspections of a specific area on some Boeing 737-300, -400 and -500 series aircraft after a report of two similarly situated cracks that went through the frame and fail-safe chord.
    “We are issuing this AD to detect and correct cracking in the fuselage frames and frame reinforcements, which could reduce the structural capability of the frames to sustain limit loads and result in cracking in the fuselage skin and subsequent rapid depressurization of the airplane,” the FAA says in AD 2011-23-05, issued on Nov. 1.
    The directive affects 605 U.S.-registered aircraft and is effective as of Nov. 16, the FAA says.
