The FAA wants to make sure certain special helicopters are safe by adding a smart device that stops a rope from accidentally unwinding too much when lifting things. They are asking people to tell them what they think about these ideas by April 25, 2025.
Summary AI
The Federal Aviation Administration (FAA) is proposing special conditions for certain Sikorsky helicopters, specifically models S-61A, S-61L, and S-61N, which are being modified by Carson Helicopters, Inc. These modifications involve installing a helicopter hoist with an overload protection device (OLPD), a feature not covered by current safety regulations. The special conditions are designed to ensure the helicopters meet necessary safety standards, addressing a new design that improves safety by preventing the hoist cable from unspooling and posing dangers to the aircraft and crew. The FAA seeks public comments on these proposed changes by April 25, 2025.
Abstract
This action proposes special conditions for a supplemental type certificate (STC) to install a helicopter hoist equipped with an overload protection device (OLPD) on Sikorsky Model S-61A, S-61L, and S-61N (including those modified by STC No. SH640NE, which shortens the S-61N by 50 inches) helicopters. These helicopters, as modified by Carson Helicopters, Inc. (Carson), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category rotorcraft. This design feature is an OLPD installed in the hoist. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The Federal Aviation Administration (FAA) has proposed special conditions tailored for specific Sikorsky helicopter models, namely the S-61A, S-61L, and S-61N. These helicopters are undergoing modifications by Carson Helicopters, Inc., which include the addition of a helicopter hoist equipped with a novel overload protection device (OLPD). This device is not yet covered under existing safety regulations. The FAA's proposal seeks to ensure these helicopters meet necessary safety standards in light of this new design feature, with public comments invited by April 25, 2025.
General Summary
The proposed changes highlight the FAA's initiative to address safety concerns related to novel helicopter equipment not covered by existing regulations. The primary goal is to enhance the safety of these helicopters by introducing specific conditions for the OLPD, which aims to prevent the hoist cable from inadvertently unspooling and causing potential hazards. This proposal affects including, but not limited to, the maximum load the device can hold and under what conditions it will activate.
Significant Issues and Concerns
One of the key concerns is the use of extensive technical jargon and acronyms, such as OLPD, STC, and AML. Without clear definitions, the document may not be easily accessible to those outside the aviation industry—including many of the general public. Such terminology could be a barrier to understanding the implications and details of the proposed conditions.
Another notable issue is the lack of a cost analysis associated with implementing these special conditions. Without understanding the financial implications, stakeholders may find it challenging to assess the economic viability or logistical burdens the changes could impose.
Additionally, the document references external sources that are not freely accessible, such as the SAE AS6342 standard. This limits transparency, as stakeholders may find it difficult to access necessary information without incurring additional costs.
Furthermore, there is minimal explanation as to why Carson Helicopters, Inc., has been chosen for these design modifications, raising potential concerns about whether the selection process is equitable or if there are underlying biases.
The technical complexity of the requirements for the OLPD's operation and activation could also pose interpretation challenges for those without specific engineering expertise, potentially leading to misunderstandings about compliance requirements.
Impact on the Public and Specific Stakeholders
For the general public, particularly those flying in or near such helicopters, the proposed safety enhancements could offer peace of mind, knowing that measures are being put in place to prevent incidents that might endanger the aircraft and its occupants. However, the technical nature of these conditions and the inherent difficulty in accessing detailed information might make it harder for the average person to fully understand these benefits.
For specific stakeholders, such as manufacturers and aviation companies, this proposal could significantly impact operations. While safety improvements are beneficial, the cost and effort required to meet these new conditions could present operational challenges or require significant changes to existing practices. The lack of clarity around cost implications complicates any strategic planning these stakeholders must undertake to implement the required changes.
Overall, while the FAA's focus on safety is commendable, ensuring transparency, accessibility, and clear communication will be crucial in successfully integrating these special conditions into aviation practices.
Issues
• The document uses technical jargon and acronyms such as OLPD, STC, and AML without providing clear definitions for readers unfamiliar with the subject matter, making it difficult for the general public to understand.
• The document does not provide a cost analysis or estimation of potential spending related to the implementation of the special conditions, leaving it unclear if there is any wasteful spending or financial implications.
• There is no discussion on why Carson Helicopters, Inc., or any associated organization, was selected for this design modification, raising questions about whether the process favors particular organizations.
• The document includes references to external documents and sources (e.g. SAE AS6342) that require purchase or are not immediately accessible to the public, limiting transparency and understanding for those who do not have access to these resources.
• The complexity of the technical requirements regarding the OLPD's functionality and activation might be difficult for stakeholders to interpret without specific engineering knowledge.
• There is insufficient information on how the FAA plans to monitor compliance with these special conditions post-implementation, which might raise concerns regarding accountability and enforcement.
