2016-11-03: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of unreliable performance of the fuel scavenge system. This AD requires changing the main fuel tank water scavenge system, center fuel tank fuel scavenge system, and certain electrical panels; doing related investigative actions; doing corrective actions if necessary; and, for certain airplanes, changing the fuel scavenge system to give redundant control of the center override/jettison fuel pumps and main jettison fuel pumps. We are issuing this AD to prevent fuel exhaustion and subsequent power loss of all engines due to loss of capability to scavenge fuel in the center fuel tank.
2016-11-08: We are superseding Airworthiness Directive (AD) 2001-12- [[Page 34877]] 18 for certain CASA Model CN-235 series airplanes. AD 2001-12-18 required modification of the rigging of the engine control cable assembly and replacement of either the entire engine control cable assembly or a segment of the control cables. This new AD would retain the requirements of AD 2001-12-18. This new AD also requires repetitive replacements of each power lever and condition lever Teleflex cable with a new or serviceable part, and removes airplanes from the applicability. This AD was prompted by reports of new occurrences of cable disruption on a certain part number; the disruption is caused by microcracks along the cable surface. We are issuing this AD to prevent fatigue of the engine control cables, leading to breakage of the cables, which could result in reduced controllability of the airplane.
2001-07-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Hartzell Propeller Inc. Y-shank series propellers, identified by hub serial numbers, that were returned to service by Brothers Aero Services Company, Inc. (BASCO). This AD requires maintenance actions amounting to an overhaul of affected propellers. This amendment is prompted by reports of propellers returned to service by BASCO as overhauled that had numerous unsafe conditions after being returned to service by BASCO. The actions specified by this AD are intended to prevent propeller failure of the propellers returned to service by BASCO, and possible loss of airplane control.
82-05-01 R2: 82-05-01 R2 EMPRESA BRASILEIRA DE AERONAUTICA S/A (EMBRAER): Amendment 39-4325 as amended by Amendment 39-4455 is further amended by Amendment 39- 4747. Applies to Models EMB-110P1 and EMB-11OP2 airplanes, certificated in any category. COMPLIANCE: Required as indicated, unless already accomplished: To prevent failure of wing flap actuators, accomplish the following: A) Within the next 50 hours time-in-service after March 1, 1982, and thereafter at intervals not to exceed 1500 landings or 12 months time-in-service, whichever occurs first. 1. Prepare the wing flap actuators for inspection by extending the flaps to the fully-extended position. CAUTION Make sure that the Battery Switch is "Off" and that flaps are not inadvertently operated while the flap actuators are being serviced. 2. Disconnect each wing flap from the actuator lug by removing the cotter pin, nut, washer and attaching bolt. CAUTION When removing the attaching bolt, provide a support for flap to prevent its rotation and possible damage. 3. Remove the safety wire and four retaining screws from the outer cover of the actuator. 4. Slide the inner and outer covers toward the reduction gearbox to expose the threaded shaft. Clean the shaft in accordance with good aircraft practices. 5. While manually retracting and extending the threaded shaft, determine: a. General condition of the shaft. b. Movement of the shaft while turning it by hand - must be free and smooth. c. Longitudinal motion of the shaft in the ballscrew/nut assembly - play must be practically undetectable by handling manually. d. That the transverse motion of the ballscrew/nut assembly, measured at the rod end of the shaft, does not exceed .20 inch (5 mm), when the shaft is fully extended, near the middle of the course, and retracted. e. General condition of the ballscrew/nut, its attachment to the main carrier tube, the fastening of the ball-return tube and the general condition of its clamp in the D2246-3 and D2246-4 actuators, and safety of the ball-return cover in the D2246-5, D2246-6, D2246-31 and D2246-41 actuators. For access, it is necessary to remove the plastic strip EEMCO P/N A12139 from the primary cover (if the plastic strip is not damaged during removal, it may be reused). (i) With the jackscrew extended, move both covers to the rod end, leaving the ball nut completely exposed. (ii) Remove all dirt and grease from the ball nuts. (iii) Check the ball-return tube fastening clamp for general condition and proper safety by attempting to move it longitudinally and rotationally. Also check the general condition and safety of the ball-return tube and for security of the ballscrew. Any indication of looseness of the ball-return tube fastening clamp or the ball-return tube is cause for replacement of the actuator. (iv) Reinstall the plastic strip P/N A12139.6. Inspect for damage and wear of sealing rings in the inner and outer actuator covers, used to protect the ballscrew and threaded shaft from moisture and dirt. 7. If any of the items inspected in Sections 5 and 6 above are not satisfactory, repair or overhaul the actuator in accordance with EEMCO Service Bulletin 27-53- 02, or replace, as necessary. 8. Lubricate the actuator and reduction gearbox: a. Remove the safety wire and upper screw where the actuator joins reduction gearbox. b. Manually extend the jackscrew to the mechanical stop. c. Inject MIL-G-23827 grease into the gearbox through the screw hole to fill the gearbox and main actuator tube. d. Temporarily install the gearbox upper screw. e. Manually retract the jackscrew until fresh grease appears between the ball nut and jackscrew. f. Remove the gearbox upper screw again to remove the excess grease by continuing to manually retract the jackscrew to the mechanical stop.g. Install the upper screw in the gearbox; safety screw with lockwire. h. Clean the main actuator tube exterior by removing all grease to prevent dust deposits. i. Lubricate the extended jackscrew by brush-daubing it with MIL- G-23827 grease. 9. Slide the outer cover aft to the proper position on the rod end cap. 10. Install the four retaining screws and safety wire. 11. Reconnect the flap to the actuator lug by installing attaching bolt, washer, nut and cotter pin. Adjust the wing flap control system to assure that the flap actuator does not contact the mechanical stop before the actuating motor stops rotating. The motor stop should be contacted, at a minimum distance of 1/4 turn, before the actuator contacts its mechanical stop for actuators P/N D2246-3, D2246-4, D2246-31, and D2246-41. The minimum distance for P/N D2246-5 and D2246-6 actuators is 1/2 turn. Damage to the mechanism may result if these distances are not maintained. 12. Check for proper operation and rigging of the wing flaps and flap position indication according to EMBRAER Technical Manual T.O. 1C95-2-5.

2022-24-16: The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted by the identification of a quality escape in the installation of certain fasteners of the lower beam (frame) splices of the overwing emergency exit (OWE) doors. This AD requires inspection, rework, if applicable, and replacement of the splice fasteners of the right-hand (RH) and left-hand (LH) OWE doors, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Copies may be obtained from Fokker Aircraft USA, Inc., 1199 North Fairfax Street, Alexandria, Virginia 22314. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. (g) This amendment becomes effective on August 18, 1993.
2001-06-10: This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-605R, A300 B4-622R, and A300 F4-605R airplanes. This AD requires repetitive high frequency eddy current (HFEC) or rototest inspections to detect cracking in the area surrounding the frame feet attachment holes between fuselage frames (FR) 41 and FR46; installation of new fasteners for certain airplanes; and follow-on corrective actions, if necessary. This AD is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent cracking of the center section of the fuselage, which could result in rupture of the frame foot and reduced structural integrity of the airplane.
