Background:

The European Aviation Safety Agency (EASA), acting as the Technical Agent for the Member States of the European Union, has issued an Emergency Airworthiness Directive (AD) numbered EASA AD 2024-0028-E on January 25, 2024. This directive addresses an unsafe condition identified in Airbus Helicopters Deutschland GmbH Model EC135 P1, EC135 P2, EC135 P2+, EC135 P3, EC135 T1, EC135 T2, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635 T2+, and EC635 T3 helicopters.

The AD was issued in response to reports of increased vibrations of the Tail Rotor (T/R) caused by a separated T/R blade due to a crack in the T/R assembly. Further investigation revealed that the affected parts may be susceptible to intergranular corrosion, potentially leading to cracks. The FAA is issuing this AD to detect and address cracks in the affected T/R blades. Failure to address this unsafe condition could result in the separation of a T/R blade assembly and subsequent loss of control of the helicopter.

Interested parties can review the EASA AD in the AD docket at regulations.gov under Docket No. FAA-2024-0453.

Related Service Information:

The FAA has reviewed EASA AD 2024-0028-E, which outlines procedures for repetitively inspecting affected T/R blades for cracks. If a crack is detected, the directive mandates replacing the affected T/R blade with a serviceable part as defined in EASA AD 2024-0028-E. Additionally, the AD allows the installation of affected parts provided they are serviceable as defined in the directive. Replacing an affected T/R blade assembly with an eligible T/R blade assembly that is not an affected part is considered terminating action for certain repetitive inspections.

This information is readily available to interested parties through their normal course of business or by referencing the details provided in the addresses section of the directive.

In addition to the EASA AD, the FAA has also reviewed Airbus Helicopters Emergency Alert Service Bulletin No. EC135-64-11-0001, Issue 001, dated January 25, 2024. This service bulletin outlines procedures for inspecting the T/R blade for cracks and replacing it if necessary.

For further information or to submit comments containing CBI, please contact Dan McCully at the FAA office in Westbury, NY.

FAA Issues AD for Airbus Helicopters Due to Unsafe Condition

The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) for certain Airbus Helicopters models due to an unsafe condition. The AD requires affected operators to take specific actions to address the issue and ensure the continued airworthiness of the helicopters.

Background

The AD is based on information provided by the European Union Aviation Safety Agency (EASA), which identified a safety concern with the affected Airbus Helicopter models. The FAA has determined that this unsafe condition is likely to exist or develop on other products of the same type design, warranting the issuance of the AD.

AD Requirements

Operators are required to comply with the actions specified in EASA AD 2024–0028–E, which has been incorporated by reference into the FAA’s AD. This includes specific inspections and maintenance procedures to address the identified safety issue. Operators must ensure compliance with the requirements outlined in the EASA AD to maintain the airworthiness of the helicopters.

Service Information

Operators are advised to refer to the service information provided in EASA AD 2024–0028–E for detailed instructions on compliance. This service information also specifies sending an affected T/R blade along with certain information to Airbus Helicopters. Compliance with the service information is essential to ensure the continued safe operation of the helicopters.

Interim Action

The FAA considers this AD to be an interim action to address the immediate safety concerns. Further rulemaking may be considered in the future to address any additional issues that may arise. Operators are urged to comply with the AD requirements promptly to prevent any potential safety hazards.

Effective Date

The FAA has determined that immediate adoption of this AD is necessary to address the identified safety concerns. Operators are required to comply with the AD requirements as soon as possible to ensure the continued airworthiness of the affected Airbus Helicopter models.

Overall, the FAA’s issuance of this AD underscores the importance of addressing safety concerns promptly to ensure the continued safe operation of aircraft. Operators are encouraged to review the AD requirements carefully and take the necessary actions to ensure compliance and the safety of their helicopters.

The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) that requires immediate action for certain helicopters due to a safety concern regarding Tail Rotor (T/R) blades. The FAA found that the risk to the flying public justifies the need for this AD without prior public comments. Section 553(d) of the Administrative Procedure Act (APA) allows agencies to make rules effective in less than thirty days upon finding good cause, which is the case with this AD.

The unsafe condition identified in the AD pertains to cracked T/R blades, which are critical to the control of a helicopter. The FAA has no information on how quickly a cracked T/R blade may lead to failure, and the affected blades are installed on high-usage helicopters, increasing the likelihood of failure. Due to these safety concerns, the FAA has determined that immediate action is necessary, with compliance required before further flight or within a short timeframe for certain helicopters.

The FAA has also found good cause to make this AD effective in less than 30 days, citing the urgency of the safety issue as the primary reason. The rapid propagation of a cracked T/R blade to failure poses a significant risk to helicopter operations, necessitating swift action to address the problem.

In terms of compliance costs, the FAA estimates that this AD affects 363 helicopters of U.S. registry. The estimated costs of compliance include labor costs for inspecting and replacing affected T/R blades. Inspecting an affected T/R blade assembly for cracks takes up to 3 work-hours and parts cost approximately $50, with potential costs of up to $3,050 per helicopter. Replacing a T/R blade takes approximately 3 work-hours and parts cost approximately $4,900, with an estimated cost of $5,155 per T/R blade.

The FAA’s authority to issue this rulemaking is derived from Title 49 of the United States Code, which outlines the FAA’s mandate to ensure aviation safety. This AD falls within the scope of the FAA’s authority to address unsafe conditions that may arise in civil aircraft.

In conclusion, the FAA’s issuance of this AD underscores the agency’s commitment to ensuring the safety of helicopter operations. By taking swift and decisive action, the FAA aims to mitigate the risks associated with cracked T/R blades and protect the flying public..

the latest trends in sustainable fashion.

Sustainable fashion has been gaining popularity in recent years as consumers become more conscious of the impact their clothing choices have on the environment. From eco-friendly materials to ethical production practices, there are many ways that fashion brands are incorporating sustainability into their designs.

One of the latest trends in sustainable fashion is the rise of circular fashion. Circular fashion is a concept that focuses on creating clothing that can be recycled, upcycled, or composted at the end of its life cycle. This means that instead of ending up in a landfill, your old clothes can be repurposed into new garments or materials, reducing waste and minimizing the environmental impact of the fashion industry.

Another trend in sustainable fashion is the use of eco-friendly materials. Many fashion brands are now using organic cotton, hemp, bamboo, and recycled materials in their designs. These materials are not only better for the environment, but they also tend to be more durable and better for your skin than traditional fabrics.

Ethical production practices are also becoming more important in the world of sustainable fashion. Many brands are now working with factories that pay fair wages and provide safe working conditions for their employees. By supporting these brands, consumers can feel good knowing that their clothes were made in an ethical and sustainable way.

Overall, the latest trends in sustainable fashion are all about reducing waste, protecting the environment, and supporting ethical practices. By choosing to invest in sustainable fashion, consumers can make a positive impact on the world while still looking stylish and on-trend. So next time you’re shopping for clothes, consider choosing sustainable options – your wardrobe and the planet will thank you for it..
