2006-16-19: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to require actions to correct the unsafe condition on these products.
2006-16-20: We are adopting a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Model DG-1000S sailplanes. This AD requires you to modify the elevator control at the stabilizer assembly, replace a placard on the fin, and incorporate changes in the FAA-approved sailplane flight manual (SFM). This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent the rigging of the horizontal stabilizer without properly connecting the elevator, which, if not prevented, could lead to an inoperative elevator. An inoperative elevator could lead to loss of control of the sailplane.
2018-16-03: We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-133 airplanes and Model A321-232 airplanes. This AD requires modification and re-identification, or replacement, of certain engine fan cowl doors (FCDs) and installation of a placard in the flight deck. This AD was prompted by reports of in-service engine FCD losses, and the development of a new FCD front latch and keeper assembly that addresses this unsafe condition. We are issuing this AD to address the unsafe condition on these products.
51-26-03: 51-26-03 CONTINENTAL: Applies to All Continental Model E185 Engines Serially Numbered 2600 and Below Which Have Not Been Major Overhauled Since November 1, 1947, by Continental Motor Corp., or July 1, 1948, by Field Overhaul Agencies. To be accomplished as soon as possible, but not later than January 1, 1952. To preclude valve failures as caused by partially deflated hydraulic valve lifters, the engine must be inspected and modified, if necessary, to assure proper oil flow to the lifters and zero valve lash under all operating conditions. This will require either a partial engine disassembly or a special test as outlined below: (1) Partial Disassembly Method: Remove the cylinders and the hydraulic units of the valve lifters. Check each valve lifter guide bore for proper position of the oil feed hole. (2) Special Test (Alternate Method): By application of air pressure to the crankcase oil galley lines after removal of each rocker arm, determine the number of degrees of crankshaft rotation that the oil groove on each valve lifter in registration with the oil feed hole. A minimum of 145 degrees registration is required. If any oil feed hole is shown by the method chosen to be drilled incorrectly, the end of the hole must be enlarged. As lack of oil flow to the rocker boxes also can result in valve mechanism malfunctioning, the diameter of the pushrod holes should be checked. If 1/32-inch diameter replace with push rods incorporating 1/16-inch diameter holes. (Continental Motors Corp. Service Bulletins Numbers M48-12 and M51-2, Supp. No. 1, cover this same subject and describe both of the above compliance methods.) This supersedes AD 51-08-01.
2006-16-10: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-200C, 747-200F, 747-300, and 747SR series airplanes. This AD requires doing repetitive inspections of engine struts 1 through 4, as applicable, for heat discoloration, cracking, buckling, or wrinkling. This AD also requires doing a conductivity test to detect the extent of the heat damage and an inspection to detect cracking of the heat-discolored, buckled, or wrinkled area; and repair; if necessary. This AD results from reports of heat damage and cracking of the skin and internal structure adjacent to and aft of the precooler exhaust vent on several engine struts. We are issuing this AD to detect and correct cracking, buckling, wrinkling, or heat damage of the skin and internal structure of the engine struts, which could result in extensive damage to the engine struts and consequent possible separation of an engine from the airplane during flight.
2018-15-06: We are adopting a new airworthiness directive (AD) for certain Honda Aircraft Company LLC Model HA-420 airplanes. This AD requires incorporating new and revised airworthiness limitations into the airplane's maintenance program. This AD was prompted by a report that several maintenance tasks were omitted from the airworthiness limitations section of the Honda Aircraft Company, Inc. Model HA-420 Airworthiness Limitation and Inspection Manual (ALIM). We are issuing this AD to address the unsafe condition on these products.
86-15-10 R2: This amendment revises an existing airworthiness directive (AD), applicable to Eurocopter France Model AS-350B, BA, B1, B2, C, D, and D1, and AS-355E, F, F1, F2 and N helicopters, that currently requires repetitive inspections of the main rotor head components, the main gearbox (MGB) suspension bars, and the ground resonance prevention system components at intervals not to exceed 400 hours time-in-service (TIS). This amendment requires the same inspections, but at intervals not to exceed 500 hours TIS. This amendment is prompted by reports of confusion and unnecessary costs associated with the difference in the current 400 hours TIS inspection interval and the current manufacturer's master service recommendation of 500 hours TIS inspection interval. The actions specified by this AD are intended to eliminate confusion and unnecessary costs and to prevent ground resonance due to reduced structural stiffness, which could lead to failure of a main rotor head or MGB suspensioncomponent and subsequent loss of control of the helicopter.
2000-07-26: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 series airplanes, that requires a one-time detailed visual inspection to detect corrosion on the outer surface of the fuselage skin panel; application of corrosion preventive protection; and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct corrosion of the fuselage skin panel, which could result in cracking and consequent reduced structural integrity of the airplane.
2006-16-08: The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires an inspection of the locking bolt of the upper attachment pin of the shock absorber on both main landing gears (MLGs) for the correct installation of the locking bolt and for any missing locking bolt, washer, nut, cotter pin, or compound, and applicable corrective action if necessary. This AD results from a report of migration and subsequent rupture of the attachment pin of the shock absorber of a MLG. We are issuing this AD to prevent failure of a MLG, which could result in significant structural damage to the airplane and possible injury to the occupants.
55-05-01: 55-05-01 BELL: Applies to All Models 47B, 47B3, 47D, 47D1, 47G Helicopters. Compliance required at the expiration of 50 flying hours total time. Twenty-five additional flying hours may be acceptable provided the inspection called for in Bell's Mandatory Service Bulletin No. 97, Revision A, is complied with. In order to prevent seizing, binding or brinelling of pitch control link bearings in the tail rotor pitch control links, P/N 47-641-032-1, it is necessary that these links be replaced with a newly designed tail rotor control link, P/N 47-641-070-1. This new control link incorporates a spherical type bearing in place of the self-aligning ball type bearing. (Bell Mandatory Service Bulletin No. 97, Revision "A" dated December 3, 1954, covers this same subject and outlines the details for the installation.)
