This action also requires, at a specified time interval, removing each affected TT strap from the helicopter, doing a visual and x-ray inspection, and replacing any unairworthy part before further flight. Reporting the discovery of any unairworthy TT strap is also required. This amendment is prompted by two recent in-flight TT strap failures. The actions specified in this AD are intended to prevent failure of a TT strap resulting in loss of directional control and subsequent loss of control of the helicopter.
2023-03-13: The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This AD was prompted by a report of a partially broken tail rotor drive fan support (fan support) and a completely broken fan support. This AD requires repetitively inspecting certain part-numbered fan supports (affected parts), and depending on the results, removing an affected part from service and replacing it with a serviceable part, which constitutes a terminating action for the repetitive inspections. This AD also requires replacing affected parts with serviceable parts unless already accomplished and prohibits installing an affected part on any helicopter, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2011-21-05: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Failures of the recline actuator metal fitting have been reported on seat backrests of in-service aircraft. * * * * * * * * Actions required by this AD are intended to prevent further failures of the seat backrests which could result in injury to passengers or crew members during an emergency landing. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2000-04-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires modification of the forward and aft evacuation slide systems by replacing the Velcro restraints for the support logs with frangible link restraints. 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 prevent the ingestion of sill support-log material into the aspirator of the escape slide, which could result in failure of the escape slide to inflate.
70-24-04: 70-24-04 CESSNA: Amdt. 39-1114. Applies to Cessna 177 Series (Serial Numbers 17700001 thru 17701530) Airplanes. Compliance: Required as indicated, unless already accomplished. To assure that the fuel shutoff valve will return to the full open position after being shut off, accomplish either Paragraph A or B as follows: A) Within 50 hours' time in service after the effective date of this AD and thereafter at intervals not to exceed 100 hours' time in service from the date of the last inspection, accomplish the following: (1) Visually inspect the operation of the fuel shutoff valve by removing the safety wire between the knob and bracket. Then pull the knob out to the full closed position followed by moving the knob forward to the full open position. (2) Check the fuel shutoff valve arm at the firewall to assure that it has returned to the full open position. (3) If the inspection discloses that the fuel shutoff valve is operating normally, reinstall .018 mild steel wire between the knob and bracket. (4) If the inspection discloses that bending of the fuel shutoff valve flexible control wire occurs between the firewall support and the shutoff valve which prevents the fuel shutoff valve from returning to the full open position, prior to further flight make the necessary replacements, adjustments or repairs to assure proper fuel shutoff valve operation, and reinstall .018 mild steel wire between the knob and bracket or alternatively install a heavier fuel shutoff valve control cable P/N S2113-1 and associated parts in accordance with Cessna Service Letter SE70-24, dated September 25, 1970, or later FAA approved revision or any other method approved as an equivalent by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

2022-27-02: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by a report of a lateral offset observed on the head-up display (HUD) of several airplanes between the synthetic vision system (SVS) and actual runway due to mechanical misalignment of the HUD during manufacturing and assembly. This AD requires revising the existing airplane flight manual (AFM) to prohibit steep approach landing (SAL) and enhanced flight vision system (EFVS) operations. This AD also requires calibrating the HUD. The FAA is issuing this AD to address the unsafe condition on these products.
96-25-03: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A and 400T series airplanes, that currently requires an inspection of certain flap roller retention components to detect discrepant or missing parts; replacement of those parts; and installation of new washers on the roller attach bolts. This amendment requires the replacement of certain previously-installed washers with new and stronger washers. This amendment also expands the applicability of the rule to include additional airplanes. This amendment is prompted by reports indicating that some locking tab washers on the roller attach bolt could fail, due to the absence of an inner tang. The actions specified by this AD are intended to prevent the loss of roller attach nuts and the flap roller, which could result in the loss of a flap when the airplane is subject to load limit conditions, and consequently lead to reduced controllability of the airplane.
