The FAA made a new rule to make sure certain planes have emergency escape hatch doors that open easily, so everyone can get out safely in an emergency. They checked the planes because some hatches were hard to open, and now they need to fix them with the right parts to keep everyone safe.
Summary AI
The Federal Aviation Administration (FAA) has issued a new rule to address safety concerns related to the emergency escape hatch on certain ATR model airplanes. The rule was prompted by a report that the hatch was difficult to open due to incorrect parts being used. This could impede a flightcrew's ability to evacuate in an emergency. The rule mandates inspections and corrective actions to fix any discrepancies, thereby ensuring these planes are safe for operation.
Abstract
The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by a report that a flight deck emergency escape hatch was difficult to open due to the hose ends being connected to the hatch with incorrect parts and/or installed collars with a too- small diameter that would not permit the drain hose to slide inside. This AD requires inspection of the flight deck emergency escape hatch drain hose for discrepancies and applicable corrective actions, and prohibits accomplishment of maintenance actions using the instructions of certain maintenance tasks, 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 rule concerning certain ATR model airplanes, specifically the ATR42 and ATR72. This regulatory action has been prompted by a safety issue involving the emergency escape hatch located on the flight deck of these aircraft. There were reports that the hatch was difficult to open due to improper parts used in its assembly, which could become problematic during an emergency evacuation.
General Summary of the Document
The document outlines an airworthiness directive (AD) mandating inspections and necessary corrective actions for the escape hatch to ensure it functions correctly. This directive is intended to rectify any improperly installed parts that might obstruct the hatch's operation, ensuring the flightcrew can evacuate quickly in an emergency.
Significant Issues or Concerns
One of the significant concerns is the document's lack of specific details regarding the cost of compliance. The FAA indicates it does not have sufficient information to estimate how many aircraft might require part replacements. This lack of clarity could leave operators uncertain about the financial implications of this directive.
Another point to consider is the use of technical language, particularly concerning the specific parts involved, like "zip-tie/ty-rap." The document assumes familiarity with such terms, which might not be the case for all stakeholders or affected parties, potentially leading to misunderstandings about what constitutes a discrepancy.
The process for operators to obtain Alternative Methods of Compliance (AMOCs) is also briefly mentioned without detailed guidance, which might create confusion for those seeking compliance alternatives.
Additionally, the document heavily relies on references to materials not directly included within the text, such as the European Union Aviation Safety Agency (EASA) directive. This approach requires stakeholders to access multiple sources to gather all necessary information, which could be an obstacle to smooth and timely compliance.
Impact on the Public
For the broader public, this new rule could enhance travel safety by ensuring that emergency escape procedures on ATR aircraft are not compromised by incorrect assembly. Passengers aboard these aircraft can have greater confidence in the safety measures in place regarding emergency egress.
Impact on Specific Stakeholders
Aircraft operators and maintenance personnel are directly affected by this rule. While the directive aims to rectify a critical safety issue, the lack of cost clarity could pose economic challenges for operators, particularly if the necessary replacements turn out to be extensive and not covered by warranty.
Manufacturers, on the other hand, may find themselves under pressure to supply compliant parts and technical guidance more expediently to meet the new regulatory requirements. Ensuring that clear and understandable maintenance procedures are widely disseminated will be crucial to avoid potential safety lapses.
Despite these challenges, the directive positively insists on higher safety standards, which could serve as a precautionary measure to align maintenance practices with broader aviation safety goals.
Overall, while this FAA rule takes a significant step towards addressing a vital safety issue, the degree of technical language, information references, and cost implications present areas that require attention to ensure clear, accessible, and economically viable enforcement.
Issues
• The document does not specify the exact cost of compliance or cost of replacement parts, indicating the FAA has no way of determining how many aircraft will need replacements. This could lead to an incomplete understanding of the economic impact on operators.
• The language used in the section describing the inspection and corrective actions for discrepancies is technical and may be difficult for non-experts to understand, such as referencing 'zip-tie/ty-rap' without further clarification for a lay audience.
• The process for obtaining Alternative Methods of Compliance (AMOCs) is briefly mentioned but not detailed, which might leave operators unclear about how to proceed with compliance alternatives.
• The document frequently references materials incorporated by reference (like EASA AD 2024-0090) without including them directly, requiring separate access by stakeholders, which could complicate comprehension and compliance.
• There is no mention of the environmental impact assessment related to this airworthiness directive or how the rule could affect sustainability practices within aviation maintenance.
• The document lacks a detailed explanation of the possible consequences if the unsafe condition (difficult hatch opening) goes unaddressed, aside from 'possibly resulting in personal injury.' More explicit potential risks might clarify the urgency and necessity more effectively.
