The FAA made a new rule for some airplanes because a part used to help them fly straight might have wrong information on it. They need to check and fix this to keep everyone safe.
Summary AI
The Federal Aviation Administration (FAA) issued a new rule affecting certain Airbus SAS airplanes based on reports of incorrect information about trimmable horizontal stabilizer actuators (THSAs). This rule mandates contacting Collins Aerospace for updated certificates and potentially replacing the affected parts to ensure safety. The FAA has implemented this rule without the usual public comment period due to the immediate safety concern, requiring compliance to prevent potential aircraft control problems. Public comments are still welcome until March 28, 2025.
Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes; Model A330-200, -200 Freighter, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of trimmable horizontal stabilizer actuators (THSAs) being delivered to operators having erroneous information (accumulated life) in the authorized release certificate. This AD requires contacting Collins Aerospace for amended authorized release certificates for the affected parts and replacing the affected parts if necessary, and prohibits the installation of affected parts, 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.

The Federal Aviation Administration (FAA) has issued a new ruling affecting several models of Airbus SAS airplanes, including models from the A318 to the A340 series. This directive, or AD, responds to reports of trimmable horizontal stabilizer actuators (THSAs) being delivered with incorrect information regarding their accumulated life on authorized release certificates. The ruling mandates contacting Collins Aerospace for updated certificates and potentially replacing parts to ensure continued airworthiness and safety. This directive becomes effective in late February 2025, yet public comments are invited until March 28, 2025.
Significant Issues and Concerns
Several significant issues arise from this document. First, the requirement to contact Collins Aerospace for amended certificates lacks clarity on what amendments are necessary and the expected timeline for completing this process. This lack of detail could lead to delays and confusion for operators trying to comply.
Another area of concern is the absence of cost estimates for the potential replacement of parts deemed necessary by this directive. Without financial estimates, operators could face budgeting challenges, as they have to prepare for potential expenditures without prior notice.
Moreover, the document's decision to implement the directive without a preliminary public comment period may create operational challenges. Operators who are unprepared for immediate compliance may find it difficult to adapt in such a short timeframe. This raises concerns about whether the FAA has sufficiently justified using an immediate rule implementation without allowing public commentary, which is typically part of such processes.
Lastly, there is complexity within the document, particularly in sections detailing procedural exceptions and compliance requirements. Such complexity may necessitate legal interpretation, posing a barrier to understanding for those without a specialized background.
Impact on the General Public
For the general public, this directive is paramount to maintaining flight safety and ensuring that aircraft components are reliable and comply with regulations. However, the immediate adoption of the rule highlights a concerning scenario that affected planes could potentially share the skies with passenger flights, necessitating swift action to mitigate risks.
Impact on Specific Stakeholders
For airlines and aircraft operators, the directive imposes an undeniably urgent requirement to act. Having to potentially replace parts and amend certificates quickly may lead to logistical and financial burdens, especially if costs are unforeseeable. Operators must also navigate complex compliance terms and perhaps adjust ongoing flight schedules and operations.
Conversely, for regulatory bodies, this directive reinforces their commitment to aviation safety and response efficiency. Also, parts manufacturers could experience increased demand as operators move to replace non-compliant parts swiftly.
Overall, while the directive serves a critical safety function, it simultaneously introduces questions and hurdles that could impose challenges upon operators due to its rapid implementation and lack of preparatory guidance. The directive's impact resonates with the necessity for proactive and coordinated industry response to avoid compromising aviation safety.
Issues
• The document mentions contacting Collins Aerospace for amended authorized release certificates, but there is no clarity on what the amendment involves or the specific timeframe for this process.
• No cost estimates are provided for the on-condition replacement of parts, which can pose budgeting challenges for operators.
• The AD is effective in less than 30 days without prior notice or comment period, which may cause operational challenges for operators unprepared for immediate compliance.
• The language used to specify procedural exceptions and compliance in paragraph (h) appears complex and may be difficult to understand without thorough legal interpretation.
• The document lacks a detailed explanation or simpler language explanation regarding why certain aircraft models are covered under the AD while others, notably not certificated by the FAA, are excluded.
• The document assumes stakeholders can easily access materials due to 'normal course of business' without considering potential accessibility barriers or costs to acquire such materials.
• There is potential ambiguity in the use of terms such as 'serviceable part' which, based on changes specified in the document, may cause confusion without further clarification.
• The immediate adoption of the rule without public comment due to 'good cause' needs clearer justification regarding the specific risk factors and why public comment is 'impracticable'.
• The list of government entities to be contacted is extensive and offers multiple points of potential failure for communication if not properly managed by the operators.
