FR 2021-01850

The document from the Federal Register proposes a new airworthiness directive by the Federal Aviation Administration (FAA) aimed at certain ATR-GIE Avions de Transport Régional Model ATR72-212A airplanes. This is a regulatory action initiated due to concerns over safety following reports of electrical control faults caused by chafing damage on electrical harnesses. The directive mandates specific modifications to aircraft components to mitigate potential hazards. The public has until April 8, 2021, to submit comments on this proposal.

General Summary

The FAA's proposed airworthiness directive seeks to address safety concerns related to specific models of ATR airplanes. These concerns were raised due to reports of engine electrical control faults linked to damage on electrical harnesses, which pose risks of short circuits and fires. The directive requires operators to modify electrical harness routes and the installation of de-icing pipe couplings. This adjustment aims to prevent future incidents that could compromise aircraft safety. The directive aligns with a similar directive from the European Union Aviation Safety Agency (EASA), indicating international collaboration on aviation safety standards.

Significant Issues and Concerns

One of the prominent issues highlighted in the document is the use of technical jargon and specific regulatory references, such as "ATA Code 92" and "EASA AD 2020-0227." For stakeholders who are not aviation specialists, deciphering these terms without a glossary might be challenging. Additionally, the procedures for submitting comments or accessing related documents are noted to be complex, potentially hindering public engagement.

The document also outlines compliance and approval requirements in detail, which may appear daunting to those unfamiliar with FAA and EASA processes. Simplifying these sections could enhance understanding and compliance.

Furthermore, the section discussing the costs associated with complying with the directive lacks detailed financial information, which could provide better transparency regarding the financial implications for stakeholders.

Impact on the Public

In broad terms, the proposed directive underscores a commitment to aviation safety, an issue that affects all who travel by air. While the proposed rule may not be directly impactful for the general public, it plays a critical role in maintaining safety standards, thereby indirectly ensuring the safety of air travelers.

Impact on Specific Stakeholders

Aircraft operators and manufacturers, particularly those operating the ATR72-212A model, are the primary stakeholders directly impacted by this proposal. They are required to implement the specified modifications, which may involve technical adjustments and associated costs. Nevertheless, addressing these safety concerns proactively can prevent more severe consequences, such as accidents, which could result in greater financial and reputational losses.

The directive also affects regulators and safety agencies by requiring coordination and oversight to ensure that modifications are carried out efficiently, keeping industry standards aligned internationally.

Overall, while the proposed directive carries immediate implications primarily for certain aviation stakeholders, its broader objective serves public interest by aiming to enhance overall safety in the aviation industry.
