That AD currently requires initial and repetitive ultrasonic inspections of the fan blade dovetail roots and defines a specific terminating action to the repetitive blade inspection requirements. This AD requires the same actions but clarifies the terminating action. We are issuing this AD to prevent multiple LPC fan blade failures due to cracks, which could result in uncontained engine failure and possible damage to the airplane. DATES: This AD becomes effective October 17, 2005. The Director of the Federal Register previously approved the incorporation by reference of certain publications listed in the regulations as of January 28, 2005 (70 FR 2336, January 13, 2005).
2018-15-05: We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-115, -132, and -133 airplanes; and Model A320- 214, -216, -232, -233, -251N, and -271N airplanes. This AD was prompted by reports of safety pins that had been installed on the inflation reservoirs of escape slides/slide rafts during production, but had not been removed. This AD requires inspecting each passenger escape slide/ slide raft to determine whether the safety pin is installed on the slide inflation reservoir, and removing any installed safety pin. We are issuing this AD to address the unsafe condition on these products.
2018-14-09: We are adopting a new airworthiness directive (AD) for certain Airbus Model A318 series airplanes; Model A319 series airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by reports of early cracking on certain holes of the crossbeam splicing at certain fuselage frames. This AD requires repetitive inspections for cracking of the fastener holes in certain fuselage frames, and depending on airplane configuration, provides an optional terminating action to the repetitive inspections. We are issuing this AD to address the unsafe condition on these products.
