2018-11-02: We are adopting a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188A and 188C airplanes; and Model P3A, P-3A, and P3B airplanes type certificated under various other type certificate holders. Certain variants of Model 188A and 188C airplanes are known as ``P-3'' series airplanes. P-3 series airplanes include but are not limited to Model CP-140, NP-3A, P3A, P-3A, P3B, P-3B, P-3C, P-3P, and WP-3D airplanes. This AD requires a borescope inspection of the aileron [[Page 23789]] control rod assembly to determine if threads exist on the aileron control rod body, and corrective actions if necessary. This AD was prompted by a report indicating that certain aileron control rod bodies were incorrectly machined so that they did not include the load- carrying threads in the bore of the aileron control rod body. As a result, aileron control rod assemblies, which contain the discrepant part, do not provide adequate load carrying capabilities. We are issuing this AD to address the unsafe condition on these products.
64-14-02: 64-14-02 de HAVILLAND: Amdt. 754 Part 507 Federal Register June 23, 1964. Applies to All Model DHC-2 Series Aircraft. Compliance required as indicated. As a result of failure of the elevator trim tab end blocks, C2TE49ND and C2TE50ND, which could lead to restriction of elevator movement, accomplish the following: (a) Within 50 hours' time in service after the effective date of this AD, unless already accomplished within the last 450 hours' time in service, and thereafter within 500 hours' time in service from the last inspection, visually inspect all four red fibre end blocks in elevator trim tabs, C2TE43A and C2TE44A, for indications of delamination, warping, and cracks, especially around the rivet holes. (b) Replace any defective part with a new part of the same part number, or an FAA approved equivalent, before further flight, except that one flight may be made in accordance with the provisions of CAR 1.76 for the purpose of obtaining these repairs. (c) The 500-hour repetitive inspections of paragraph (a) need not be made on aircraft which already incorporate fabric-base phenolic end blocks and may be eliminated on aircraft that are modified by replacing the red fibre end blocks with blocks manufactured from plastic sheet, laminated, thermosetting, cotton fabric-base, phenolic resin MIL-P-15035C Type FBG (general purpose grade), or an FAA-approved equivalent in accordance with the procedure outlined in de Havilland Engineering Bulletin Series "B", No. 30, dated October 15, 1963. (de Havilland Engineering Bulletin Series "B", No. 30, dated October 15, 1963, available from de Havilland Aircraft of Canada, Ltd, Toronto, Canada, covers this same subject.) This directive effective July 24, 1964.
2018-10-10: We are superseding Airworthiness Directive (AD) 2017-01-12, AD 2017-11-08, and AD 2017-15-09 for certain Diamond Aircraft Industries GmbH Model DA 42 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as uncommanded engine shutdown during flight due to failure of the propeller-regulating valve caused by hot exhaust gases coming from fractured engine exhaust pipes. We are issuing this AD to require actions to address the unsafe condition on these products.
46-50-01: 46-50-01 WACO: (Was Special Note 2 of AM-166.) Applies to Models INF, KNF, MNF, RNF Aircraft. Inspection required before next flight - rework (if needed) not later than April 1, 1946. Inspect the fuel line (or lines) connecting the fuel strainer and the carburetor to determine that this line is made up of either: (a) Rigid metal tubing with flexible hose connections at each end, or (b) Approved type flexible hose assembly. Aircraft found to have fuel line installations not conforming to either (a) or (b) shall be altered to conform as soon as possible. (Waco Service Bulletin No. 154 also covers this subject.)

2018-09-51: We are adopting a new airworthiness directive (AD) for CFM International, S.A., (CFM) CFM56-7B model engines. This emergency AD was sent previously to all known U.S. owners and operators of CFM CFM56-7B model engines. This AD requires a one-time ultrasonic inspection (USI) of the concave and convex sides of the fan blade dovetail. This AD was prompted by a recent engine failure due to a fractured fan blade, which resulted in the engine inlet cowl disintegrating and debris penetrating the fuselage, causing a loss of pressurization, and prompting an emergency descent. We are issuing this AD to address the unsafe condition on these products.
