2007-26-06: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-200B, 747-300, and 747-400 series airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service units of the outboard and center main deck, the flight attendant service units, flightcrew rest, upper and lower module of the door 5 overhead crew rest, lavatory modules, and miscellaneous ceiling panels, as applicable, and related investigative/corrective actions if necessary. This AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.
2001-12-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 series airplanes, that requires repetitive detailed visual and ultrasonic inspections of the lower flange of the flaperon inboard support to find cracking, and corrective actions, if necessary. This AD also requires a modification, which terminates the repetitive inspections. The actions specified by this AD are intended to prevent fracture of the inboard support structure, which could result in an in-flight loss of the inboard flaperon, structural damage, and consequent reduced controllability of the airplane.
2020-03-10: The FAA is adopting a new airworthiness directive (AD) for The Boeing Company Model 737 series airplanes, except for Model 737-100, - 200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of separation of the lower aft wing-to-body fairing panel 194E (''fairing panel 194E'') during flight, due to worn or damaged nutplates on the \n\n((Page 10037)) \n\nsupport structure. This AD requires repetitive inspections for discrepancies of fairing panel 194E, wheel well panel 193D, and support structure, and related investigative and corrective actions if necessary. This AD also requires rework of the panels and support structure, which terminates the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.

Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to the Lockheed-Georgia Company, 86 South Cobb Drive, JetStar Customer Support, Dept. 64-26, Zone 668, Marietta, Georgia 30063; or AiResearch Aviation Company, Customer Support Department, 6201 West Imperial Highway, Los Angeles, California 90045. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or at4344 Donald Douglas Drive, Long Beach, California. This Amendment, 39-5683, becomes effective August 26, 1987.
94-12-10: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires repetitive inspections, tests, adjustments, and functional checks of the thrust reverser system and of selected engine wiring. This amendment adds a requirement for installation of a terminating modification, repetitive operational checks of that installation, and repair of any discrepancy found. This amendment is prompted by the identification of a modification that ensures that the level of safety inherent in the original type design of the thrust reverser system is further enhanced. The actions specified by this AD are intended to prevent deployment of a thrust reverser in flight and subsequent reduced controllability of the airplane.
2007-25-20: The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10- 40F airplanes; and Model MD-11 and MD-11F airplanes. This AD requires, for certain airplanes, modifying the thrust reverser command wiring of the number 2 engine. For certain other airplanes, this AD requires modifying the thrust reverser system wiring from the flight compartment to engines 1, 2, and 3 thrust reversers. This AD also requires installing thrust reverser locking systems on certain airplanes. This AD results from a determination that the thrust reverser systems on these McDonnell Douglas airplanes do not adequately preclude unwanted deployment of a thrust reverser. We are issuing this AD to prevent an unwanted deployment of a thrust reverser during flight, which could result in reduced controllability of the airplane.
2001-12-06: This amendment adopts a new airworthiness directive (AD), that is applicable to GE CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 turbofan engines with No. 5 bearing rotating air seal part number (P/N) 4019T60G01 installed. This amendment requires initial and repetitive checks of the magnetic chip detector indicators, which are located in the lubrication system for the engine bearings, and installation of an improved No. 5 bearing rotating air seal as a terminating action. This amendment is prompted by a report of the failure of a No. 5 that led to a fire in the cavity of the low pressure turbine (LPT), overtemperature of the LPT turbine disk, and excessive turbine disk growth. The actions specified by this AD are intended to prevent No.5 bearing rotating air seal failures and possible uncontained engine failures.
2001-12-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Learjet Model 55 series airplanes and Model 60 airplanes, that requires replacement of the brake valve adjustment screw with a new improved screw, and for certain airplanes, it would also require installation of a new brake valve lever stop. The actions specified by this AD are intended to prevent bottoming of the valve components before contact of the brake valve lever with the stop, which could result in loss of all hydraulic fluid and consequent loss of normal braking. This action is intended to address the identified unsafe condition.
2001-12-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-300 series airplanes, that requires a one-time general visual inspection to find chafing and determine adequate clearance of certain wire bundles in the ceiling panel near the main passenger door, and corrective actions. The actions specified by this AD are intended to prevent damage to the wires in the bundles due to contact between the bundles and the adjacent ceiling support bracket. Such damage could result in electrical arcing, smoke, or fire in the cabin, and failure of certain systems essential to safe flight and landing of the airplane. This action is intended to address the identified unsafe condition.
2007-26-01: We are adopting a new airworthiness directive (AD) for certain Thrush Aircraft, Inc. (Thrush) Model S2R series airplanes. This AD requires you to do repetitive visual inspections of the vertical and horizontal stabilizer attach fitting, attach fitting bolts, and the vertical fin aft spar for cracks or corrosion. This AD also requires immediate replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if cracked or corroded parts are found, and the inspection of the vertical fin aft spar with repair or replacement if cracks or corrosion are found. This AD requires the eventual replacement of the vertical and horizontal stabilizer attach fittings and attach fitting bolts if no corrosion or cracks are found as terminating action for the repetitive inspections. This AD results from reports of cracks in the empennage of Thrush S2R series airplanes. We are issuing this AD to detect and correct these cracks, which could cause the vertical stabilizer to lose structural integrity. This failure could lead to loss of control.
