2017-04-09: We are superseding Airworthiness Directive (AD) 2012-22-12 for all Airbus Model A330-243, -243F, -341, -342, and -343 airplanes. AD 2012-22-12 required inspecting piccolo tubes and mount links, the aft side of the forward bulkhead, and outer boundary angles (OBAs); and doing corrective actions if necessary. This new AD retains certain requirements of AD 2012-22-12, and adds inspections of certain areas of the forward bulkhead, and related investigative and corrective actions if necessary. This AD was prompted by reports of cracking of air intake cowls, worn and detached attachment links, fractured thermal anti-ice (TAI) piccolo tubes, and loose or missing attachment rivets of the inner boundary angles (IBAs) and OBAs of the forward bulkhead. We are issuing this AD to address the unsafe condition on these products.
2017-04-04: We are superseding Airworthiness Directive (AD) 2012-16-08 for certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes. AD 2012-16-08 required repetitive inspections for bulging, surface anomalies, and cracking of the fuselage skin adjacent to the discharge valves, and repair and application of additional sealant in the affected area if necessary. This new AD retains the requirements of AD 2012-16-08, expands the applicability, and requires an additional one-time inspection for the presence of water traps/air driers to determine which airplanes must be inspected. This AD was prompted by reports of cracking and surface anomalies of the fuselage skin at the water trap/air drier unit of the forward discharge valve due to corrosion, and the determination that airplanes on which a certain auto-pressurization modification was incorporated during production were excluded from the applicability of AD 2012-16-08, but are also affected by this condition.We are issuing this AD to address the unsafe condition on these products.
70-04-01: 70-04-01 MCCAULEY PROPELLERS: Amdt. 39-939. Applies to 2D36C14- (X)/78KM, 2D34C53-(X)/74E, and B2D34C53-(X)/74E propellers on Lycoming O-360 type engines. Compliance required within the next 25 hours time in service after the effective date of this AD, unless already accomplished. To prevent propeller mid-blade and tip failures accomplish the following: a. Visually inspect blades for foreign object damage or cracks. b. If blade is damaged, repair in accordance with instructions in McCauley Service Bulletin No. 76 dated 28 November 1969, or an equivalent method approved by the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region. Replace any cracked blades before further flight with a new blade which has been inspected and repaired if necessary in accordance with this AD. c.

This amendment is effective February 20, 1970.
2006-22-06: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65. The existing AD currently requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. For certain airplanes, the existing AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. This AD requires revising the same Emergency and Abnormal Procedures sections of the AFM to advise the flightcrew of revised/additional procedures. This AD also requires revising the Normal section of the AFM to require a review of the location of certain circuit breakers and a functional check of the stabilizer trim system. This AD also requires installing circuit breaker identification collars and provides an optional terminating action for the requirements of the AD. This AD also removes airplanes from the applicability of the existing AD. This AD results from reports of uncommanded horizontal stabilizer trim motion. We are issuing this AD to ensure that the flightcrew is advised of appropriate procedures to follow in the event of uncommanded movement or stabilizer trim runaway. Failure to follow these procedures could result in excessive uncommanded movement of the horizontal stabilizer trim actuator (HSTA) and loss of ability to use trim switches to override uncommanded movement or yoke disconnect switches to disconnect the HSTA, which could result in reduction of or loss of pitch control and consequent reduced controllability of the airplane. \n\n\nDATES: This AD becomes effective November 14, 2006. \n\n\tThe Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of November 14, 2006. \n\n\tOn September 1, 2006 (71 FR 51990, September 1, 2006), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD. \n\n\tWe must receive any comments on this AD by December 29, 2006.
2017-04-02: We are superseding Airworthiness Directive (AD) 2014-23-06 for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2014-23-06 required modifying the main landing gear (MLG) by installing a new bracket on the left and right lower aft-wing planks. This new AD requires modification of the MLG with an improved design. This AD was prompted by a report indicating that inboard and outboard hydraulic lines of the brakes were found connected to the incorrect ports on the swivel assembly of the MLG. We are issuing this AD to address the unsafe condition on these products.
2017-03-02: We are superseding airworthiness directive (AD) 2014-16-10 for all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2014-16-10 required initial and repetitive ultrasonic inspections (UIs) of the affected low-pressure (LP) compressor blades. This AD requires the UIs in AD 2014-16-10 while reducing the inspection threshold. This AD was prompted by revised service information to reduce the inspection threshold for UI of the LP compressor blades. We are issuing this AD to correct the unsafe condition on these products.
50-46-01: 50-46-01 DOUGLAS: Applies to All Models DC3 and C-47 Series Aircraft Which Utilize a Standpipe in the Engine Oil Tank for Propeller Feathering Oil Reserve. \n\n\tCompliance required not later than the first engine change after December 1, 1950. \n\n\tThere have been several cases of inability to feather the propeller due to inadequate feathering oil supply, following loss of engine oil. To correct this condition ascertain the quantity of oil retained in the tank by the propeller feathering standpipe with the airplane in the level flight attitude. If the quantity so retained is less than 1 1/2 gallons, rework the standpipe so that at least this quantity is retained. \n\n\tAircraft employing C-47 type oil tanks, Douglas P/N 5110511 with Douglas P/N 1355088 standpipe will be considered satisfactory.

2016-25-15: We are superseding Airworthiness Directive (AD) 2011-17-05, for certain Airbus Model A300 B2-1C, A300 B2-203, A300 B2K-3C, A300-B4- 103, A300 B4-203, and A300 B4-2C airplanes. AD 2011-17-05 required repetitive inspections in sections 13 through 18 of the fuselage between rivets of the longitudinal lap joints between frames (FRs) 18 and 80 for cracking, and repair or modification if necessary. This new AD requires a revised repetitive inspection program of all longitudinal lap joints and repairs between FRs 18 and 80 to address widespread fatigue damage (WFD). This AD was prompted by an evaluation done by the design approval holder indicating that certain sections of the longitudinal lap joints are subject to WFD; therefore, a revised inspection program is necessary. We are issuing this AD to address the unsafe condition on these products.
