17th Meeting: RTCA Special Committee 206/EUROCAE WG 76 Plenary
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 206: Aeronautical Information Services Data Link.
Special Conditions: Boeing Model 757 Series Airplanes; Seats with Non-Traditional, Large, Non-Metallic Panels
These special conditions are issued for Boeing Model 757 series airplanes. These airplanes, as modified by Northwest Airspace Technologies, Inc., will have a novel or unusual design feature associated with seats that include non-traditional, large, non-metallic panels that would affect survivability during a post-crash fire event. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Short Brothers Model SD3-60 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would revise an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 737-100, -200, -200C, - 300, -400, and -500 series airplanes. The existing AD currently requires a one-time inspection for scribe lines and cracks in the fuselage skin at certain lap joints, butt joints, external repair doublers, and other areas; and related investigative/corrective actions if necessary. This proposed AD would expand the area to be inspected and, for certain airplanes, require earlier inspections for certain inspection zones. This proposed AD results from additional detailed analysis of fuselage skin cracks adjacent to the skin lap joints on airplanes that had scribe lines; the analysis resulted in different inspection zones, thresholds and repetitive intervals, and airplane groupings. We are proposing this AD to prevent rapid decompression of the airplane due to fatigue cracks resulting from scribe lines on pressurized fuselage structure.
Airworthiness Directives; Lockheed Model 382, 382B, 382E, 382F, and 382G Series Airplanes
We are adopting a new airworthiness directive (AD) for all Lockheed Model 382, 382B, 382E, 382F, and 382G series airplanes. This AD requires an inspection to identify discrepant barrel nuts in the upper wing joint, engine truss, and rear beam pylon support; and replacement of any discrepant barrel nut with a new barrel nut, if necessary. This AD results from a report of severe cracking of multiple barrel nuts in the wing station (WS) 220 upper wing joint found during scheduled maintenance. We are issuing this AD to prevent cracking of the barrel nuts in the upper wing joint, engine truss, and rear beam pylon support, which could result in reduced structural integrity of the affected part and consequent detachment of the wing or engine from the airplane.
Airworthiness Directives; Hartzell Propeller Inc. Steel Hub Turbine Propellers
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. steel hub turbine propellers, with any counterweight slug attachment bolts, part number (P/N) B-3386-14H, LFC manufacturing lot 224, installed. This AD requires identifying and removing all counterweight slug attachment bolts, P/N B-3386-14H, LFC manufacturing lot 224, from service and installing serviceable bolts. This AD results from two reports of failure of the bolts that attach the propeller blade counterweight slug, and separation of the counterweight slug which led to propeller vibration and damage to the propeller spinner. We are issuing this AD to prevent separation of the propeller blade counterweight slug, which could lead to injury and damage to the airplane.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 747 airplanes. The existing AD currently requires modifying the inflation systems of the upper deck escape slides; single-piece off-wing escape ramps/slides; two-piece off-wing escape slides; and door 1, 2, 4, and 5 escape slides/rafts; as applicable. This AD expands the applicability to include an additional airplane. This AD results from a report of 30- to 60-second delays in the inflation of escape slides/rafts. We are issuing this AD to prevent actuation delays in the inflation systems of the escape slides/rafts, which could result in delayed or failed deployment of escape slides/ rafts during emergency evacuation of an airplane.
Airworthiness Directives; Airbus Model A330-300, A340-200, and A340-300 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
