2019-08-12: We are adopting a new airworthiness directive (AD) for certain Viking Air Limited Model CL-215-6B11 (CL-215T Variant) and CL-215-6B11 (CL-415 Variant) airplanes. This AD was prompted by a report that a supplier fabricated Teflon parts with a charge of 15 percent fiberglass content instead of the specified 5 percent fiberglass content. This AD requires repetitive detailed visual inspections of the aileron control system cables and flap interconnect system cables for damage or disconnected cables, corrective actions if necessary, and replacement of the Teflon parts in the aileron control systems, aileron/rudder interconnect, and aileron power unit beam. The replacement of these parts terminates the repetitive inspections. We are issuing this AD to address the unsafe condition on these products.
98-11-31: This amendment adopts a new airworthiness directive (AD) that applies to all British Aerospace (BAe) Jetstream Model 3101 airplanes equipped with a certain autopilot. This AD requires modifying the autopilot elevator electric system relays by installing two additional relays and associated wiring changes in the relay box located under the right hand crew seat. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to prevent failure of the autopilot elevator electric system relays for the up and down trim interlocks, which could result in uncommanded trim servo operation and possible loss of control of the airplane.
99-03-09: This amendment adopts a new airworthiness directive (AD) that is applicable to Allison Engine Company, Inc. AE 2100A, AE 2100C, and AE 2100D3 series turboprop engines. This action requires removing from service affected turbine wheels prior to exceeding new, reduced cyclic life limits. This amendment is prompted by the results of a refined life analysis. The actions specified in this AD are intended to prevent an uncontained turbine wheel failure, which could result in damage to the aircraft.
2019-08-06: We are superseding Airworthiness Directive (AD) 2016-16-01, which applied to certain Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes. AD 2016-16-01 required an inspection of affected structural parts in the cargo and cabin compartments to determine if proper heat treatment has been done, and replacement or repair if necessary. This AD retains the requirements of AD 2016-16-01 and requires inspection of additional locations of the cabin compartment structure. This AD was prompted by a report of a manufacturing defect (i.e., improperly heat-treated materials) that affects the durability of affected parts in the cargo and cabin compartments. We are issuing this AD to address the unsafe condition on these products.
2006-20-10: We are adopting a new airworthiness directive (AD) for certain Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. This AD requires you to repetitively inspect the attach angles on the firewall mounted hopper rinse tank shelf for damage and/or cracks and replace damaged and/or cracked attach angles with steel attach angles. Replacing the attach angles with steel attach angles terminates the repetitive inspection requirement. Reports of an uncommanded change in the engine power setting caused by separation of the hopper rinse tank shelf from the firewall prompted this AD. We are issuing this AD to detect and correct damage and/or cracks in the attach angles on the firewall mounted hopper rinse tank shelf, which could result in failure of the attach angles. This failure could lead to shelf movement under maneuver load and shifting of the engine power cables, which could result in an uncommanded engine power setting change.
98-04-25: This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company Model 2000 airplanes. This action requires revising the FAA-approved Airplane Flight Manual (AFM) to specify procedures that would prohibit flight in severe icing conditions (as determined by certain visual cues), limit or prohibit the use of various flight control devices while in severe icing conditions, and provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions. This AD is prompted by the results of a review of the requirements for certification of these airplanes in icing conditions, new information on the icing environment, and icing data provided currently to the flight crew. The actions specified by this AD are intended to minimize the potential hazards associated with operating these airplanes in severe icing conditions by providing more clearly defined procedures and limitations associated with such conditions.
2006-20-03: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This AD requires an inspection to determine if the stiff part of the girt and girt bar position of the forward left-hand and right-hand passenger doors is incorrect, and repair if necessary. This AD results from cases of girt bar disengagement from the floor fitting during deployment tests of slide rafts at the forward passenger doors. We are issuing this AD to prevent disengagement of the telescopic girt bar from the airplane when the door is opened in emergency situations, which could result in the inability to open the passenger door and to use the escape slide/raft at that door during an emergency evacuation of the airplane.
2019-08-01: We are adopting a new airworthiness directive (AD) for certain RECARO Aircraft Seating GmbH & Co. KG (RECARO) Model 3510A and 3510D passenger seats. This AD requires modification and re-identification of all affected RECARO model passenger seats. This AD was prompted by an analysis that the affected RECARO model passenger seats contain a seat pan assembly design that can trap a person using the seat to assist during an emergency evacuation. We are issuing this AD to address the unsafe condition on these products.
