Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

The FAA adopts a new airworthiness directive (AD) for certain Extra Flugzeugproduktions-und Vertriebs-GmbH (EXTRA) Models EA-300, EA-300S, EA-300L, and EA-300/200 airplanes. This AD requires you to seal with firewall sealant the gaps between the bottom fuselage cover (belly fairing) and the firewall and repeat the sealing procedure whenever you install the bottom fuselage cover (belly fairing). This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent fuel from flowing behind the firewall in the case of a fuel leak. This could result in an in-flight fire, which could cause loss of the airplane and crew.

DATES:

This AD becomes effective on July 18, 2005.

As of July 18, 2005, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.

Discussion

What events have caused this AD? The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority for Germany, recently notified FAA that an unsafe condition may exist on certain Extra Flugzeugproduktions-und Vertriebs-GmbH (EXTRA) Models EA-300, EA-300S, EA-300L, and EA-300/200 airplanes. The LBA reports an incident of a fire in the engine compartment on one of the affected airplanes due to a leaking gascolator. Evidence showed that the spilled fuel had leaked down the firewall and through the non-sealed connections between the firewall and the bottom fuselage cover (belly fairing). The fire in the engine compartment spread to the cabin and resulted in loss of the airplane.

What is the potential impact if FAA took no action? A fuel leak behind the firewall could result in an in-flight fire, which could cause loss of the airplane and crew.

Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Extra Flugzeugproduktions-und Vertriebs-GmbH (EXTRA) Models EA-300, EA-300S, EA-300L, and EA-300/200 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on April 1, 2005 (70 FR 16771). The NPRM proposed to require you to seal with firewall sealant the gaps between the bottom fuselage cover (belly fairing) and the firewall and whenever you install the bottom fuselage cover (belly fairing).

Comments

Was the public invited to comment? We provided the public the opportunity to participate in developing this AD. We received no comments on the proposal or on the determination of the cost to the public.

Conclusion

What is FAA's final determination on this issue? We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:

—Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and

—Do not add any additional burden upon the public than was already proposed in the NPRM. Start Printed Page 32991

Changes to 14 CFR Part 39—Effect on the AD

How does the revision to 14 CFR part 39 affect this AD? On July 10, 2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.

Costs of Compliance

How many airplanes does this AD impact? We estimate that this AD affects 199 airplanes in the U.S. registry.

What is the cost impact of this AD on owners/operators of the affected airplanes? We estimate the following costs to seal with firewall sealant the gaps between the bottom fuselage cover (belly fairing) and the firewall:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
1 work hour × $65 per hour = $65$140$205$205 × 199 = $40,795

Authority for This Rulemaking

What authority does FAA have for issuing this rulemaking action? Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.

We are issuing this rulemaking under the authority described in Subtitle VII, part A, subpart III, section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this AD.

Regulatory Findings

Will this AD impact various entities? We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

Will this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this AD:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “Docket No. FAA-2005-20588; Directorate Identifier 2005-CE-11-AD” in your request.
