AD 2020-22-09 Requires A Roto-Test Inspection Of Fastener Holes Of Certain Fuselage Joints

The FAA is superseding Airworthiness Directive (AD) 2001-16-13, which applied to certain Airbus SAS Model A330 series airplanes. AD 2001-16-13 required a roto-test inspection of fastener holes of certain fuselage joints for cracks, reinforcement of the fuselage between certain frames, and, if necessary, a high frequency eddy current (HFEC) inspection and repair. As published, the applicability of AD 2001-16-13 inadvertently identified the model designations as serial numbers. This document corrects that error. This new AD requires a roto-test inspection of fastener holes of certain fuselage joints for cracks, reinforcement of the fuselage, and, if necessary,

AD 2020-22-18 Prompted By A Report Of A Propeller Gearbox (PGB) Development Test Conducted By The Manufacturer

The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Corporation (RRC) AE 2100A, AE 2100D2, AE 2100D2A, and AE 2100P model turboprop engines.  This AD was prompted by a report of a propeller gearbox (PGB) development test conducted by the manufacturer, in which high vibration occurred due to a fatigue crack that initiated in the PGB shaft and carrier assembly. This AD requires assignment of usage hours to the PGB shaft and  carrier assembly at the next engine shop visit and replacement of PGB shaft and carrier assemblies prior to exceeding the new life limits established by the manufacturer. The FAA is
