Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain aviation tires installed on various transport category airplanes. This proposed AD would require a one-time inspection of the nosewheel tires to determine if they are within a designated serial number range, and replacement if necessary. This proposed AD results from reports of tread separations and tread-area bulges on the nosewheel tires. We are proposing this AD to prevent tread separation from a nosewheel tire during takeoff or landing, which could result in compromised nosewheel steering or ingestion of separated tread by an engine, and consequent reduced controllability of the airplane on the runway or in the air.

DATES:

We must receive comments on this proposed AD by June 19, 2006.

Discussion

We have received reports of tread separations and tread-area bulges on certain Goodyear Aviation nosewheel tires that are within a designated serial number range. Investigation revealed that the nosewheel tires have poor adhesion properties, which could cause tread loss during takeoff or landing. This condition, if not corrected, could result in compromised nosewheel steering or ingestion of separated tread by an engine, and consequent reduced controllability of the airplane on the runway or in the air.

Relevant Service Information

We have reviewed Goodyear Aviation Service Bulletin SB-2005-32-004, Revision 5, dated December 22, 2005. The service bulletin describes procedures for inspecting the nosewheel tires for the affected serial numbers, and for replacing affected tires. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition.

We have also reviewed the following Gulfstream Alert Customer Bulletins. These Alert Customer Bulletins, all dated October 12, 2005, are additional sources of service information for identifying the affected serial numbers and replacing the tires if necessary. Start Printed Page 25988

FAA's Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in the Goodyear Aviation service information described previously, except as discussed under “Differences Between the Proposed AD and the Service Information.”

Differences Between the Proposed AD and the Service Information

Although the Goodyear Aviation service bulletin specifies a compliance time of 14 days for replacing affected tires, this proposed AD would require a compliance time of 60 days for doing the replacement. Most have complied with the proposed requirements, and the majority of the affected tires have been removed from service. Therefore, a compliance time of 60 days would ensure that the remainder of the tires are removed from service within a time that does not compromise safety.

Although the Goodyear Aviation service bulletin specifies to return tires to the manufacturer, this proposed AD would not require that action.

Explanation of Service Bulletin Revisions

This proposed AD would give credit to operators for previous accomplishment of the original release of Goodyear Aviation Service Bulletin SB-2005-32-004, dated October 11, 2005, but not for accomplishment of revisions 1 through 4 of the service bulletin. Revisions 1 through 4 of the service bulletin were internal to Goodyear and were not released to operators.

Costs of Compliance

There are about 1,282 Gulfstream airplanes and about 104 Bombardier airplanes that use the affected tires in the worldwide fleet. This proposed AD would affect about 1,035 Gulfstream airplanes, and about 104 Bombardier airplanes of U.S. registry. The proposed inspection for the affected serial numbers would take about 1 work hour per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $91,120, or $80 per airplane.

Authority for This Rulemaking

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 rulemaking action.

Regulatory Findings

We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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.

For the reasons discussed above, I certify that the proposed regulation:

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 regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
