These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
The FAA proposes to supersede Airworthiness Directive (AD) 2013-08-16, which applies to certain The Boeing Company Model 737-700 and -700C series airplanes. AD 2013-08-16 requires repetitive inspections for cracking of the fuselage skin at certain locations at chem-mill areas and repair if necessary. Since the FAA issued AD 2013- 08-16, the FAA has determined that the compliance times are not adequate. This proposed AD would continue to require the actions in AD 2013-08-16 but at reduced compliance times and would require post- modification inspections if an optional modification is accomplished. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and 767-300 series airplanes. This proposed AD was prompted by reports of scribe lines found at skin lap joints and butt joints, around external repairs and antennas, and at locations where external decals had been cut. For some airplanes, this proposed AD would require a detailed inspection for scribe lines and applicable related investigative and corrective actions. For other airplanes, this AD would require repetitive nondestructive testing inspections for cracking at certain stringers of the skin lap joint fuselage skin and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

This proposed AD would require inspecting the elevator drive fitting to determine the type of lower ball bearing installed, and depending upon the results, replacing the lower ball bearing with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2013-08-15, which applies to certain The Boeing Company Model 737-800 series airplanes. AD 2013-08-15 requires repetitive inspections for cracking of the fuselage skin along chem-mill steps at certain crown skin and shear wrinkle areas and repair if necessary. Since the FAA issued AD 2013-08-15, the FAA has determined that the compliance times are not adequate. This proposed AD would continue to require the actions in AD 2013-08-15 but at reduced compliance times and would require post-modification inspections if an optional terminating action is accomplished. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2020-12- 12, which applied to all Embraer S.A.
