Airworthiness Directives; Goodyear Tire and Rubber Company Flight 
Eagle Tires, 34X9.25-16 18PR 210MPH, Part Number 348F83-2

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Goodyear Tire and Rubber Company (Goodyear) Flight 
Eagle tires, 34X9.25-16 18PR 210MPH, Part Number (P/N) 348F83-2, that 
are installed on aircraft. This AD requires you to inspect these tires 
to determine if they are within a certain serial number range and 
replace any tires within this serial number range. This AD is the 
result of several instances of main landing gear (MLG) tire tread 
separations on Gulfstream aircraft. The actions specified by this AD 
are intended to remove these tires from service to prevent the 
potential of these tires experiencing tread separations during 
operation. These tread separations could result in structural damage to 
the aircraft, including damage to the flaps, engine nacelles, and wheel 
wells.

DATES: This AD becomes effective on September 24, 2001.
    The FAA must receive any comments on this rule on or before October 
12, 2001.

ADDRESSES: Submit comments in triplicate to FAA, Central Region, Office 
of the Regional Counsel, Attention: Rules Docket No. 2001-CE-27-AD, 901 
Locust, Room 506, Kansas City, Missouri 64106.

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA has received reports of four incidents of main landing gear 
(MLG) tire tread separations on Gulfstream aircraft. Two of these 
incidents occurred during takeoff, and the other two are being 
investigated.
    Goodyear has identified a batch of Flight Eagle tires, 34X9.25-16 
18PR 210MPH, Part Number (P/N) 348F83-2, that are susceptible to the 
tire tread separations. The serial numbers of this batch are 0168xxxx 
through 0185xxxx. This consists of approximately 300 tires.
    These tires are installed on, but not limited to, the following 
aircraft:

What Are the Consequences if the Condition Is Not Corrected?

    Tire tread separations, if not prevented, could result in 
structural damage to the aircraft. This includes damage to the flaps, 
engine nacelles, and wheel wells.

Is There Service Information That Applies to This Subject?

    Goodyear has issued Service Bulletin GY SB 2001-32-006, dated July 
28, 2001. In addition, Gulfstream Aerospace Corporation has issued 
Alert Customer Bulletins #28 (GII/GIIB), #14 (GIII), and #28 (GIV), all 
dated July 31, 2001.
    These bulletins provide information that relates to removing the 
affected tires from service.

The FAA's Determination and an Explanation of the Provisions of 
This AD

What Has FAA Decided?

    After examining the circumstances and reviewing all available 
information related to the subject above, we have determined that:

--The unsafe condition referenced in this document exists or could 
develop on type design aircraft equipped with certain Goodyear Flight 
Eagle tires, 34X9.25-16 18PR 210MPH, P/N 348F83-2, serial numbers 
0168xxxx through 0185xxxx;
--These tires should be removed from service; and
--AD action should be taken in order to correct this unsafe condition

What Would This AD Require?

    This AD requires you to inspect all of these tires to determine if 
they are within the affected serial number range and replace any tires 
within this serial number range.

Will I Have the Opportunity to Comment Prior to the Issuance of the 
Rule?

    Because the unsafe condition described in this document could 
result in structural damage to the aircraft, including damage to the 
flaps, engine nacelles, and wheel wells, FAA finds that notice and 
opportunity for public prior comment are impracticable. Therefore, good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

How Do I Comment on This AD?

    Although this action is in the form of a final rule and was not 
preceded by notice and opportunity for public comment, we invite your 
comments on the rule. You may submit whatever written data, views, or 
arguments you choose. You need to include the rule's docket number and 
submit your comments in triplicate to the address specified under the 
caption ADDRESSES. We will consider all comments received on or before 
the closing date specified above. We may amend this rule in light of 
comments received. Factual information that supports your ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether we need to take additional rulemaking 
action.

Are There Any Specific Portions of the AD I Should Pay Attention to?

    The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. You may examine all comments we 
receive before and after the closing date of the rule in the Rules 
Docket. We will file a report in the Rules Docket that summarizes each 
FAA contact with the public that concerns the substantive parts of this 
AD.
    We are reviewing the writing style we currently use in regulatory 
documents, in response to the Presidential memorandum of June 1, 1998. 
That memorandum requires federal agencies to communicate more clearly 
with the public. We are interested in your comments on whether the 
style of this document is clear, and any other suggestions you might 
have to improve the clarity of FAA communications that affect you. You 
can get more information about the Presidential memorandum and the 
plain language initiative at http://www.plainlanguage.gov.

How Can I Be Sure FAA Receives My Comment?

    If you want us to acknowledge the receipt of your comments, you 
must include a self-addressed, stamped postcard. On the postcard, write 
``Comments to Docket No. 2001-CE-27-AD.'' We will date stamp and mail 
the postcard back to you.

Regulatory Impact

Does This AD Impact Various Entities?

    These regulations 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. Therefore, FAA has determined that this 
final rule does not have federalism implications under Executive Order 
13132.

Does This AD Involve a Significant Rule or Regulatory Action?

    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and is not a significant regulatory action under 
Executive Order 12866. It has been determined further that this action 
involves an emergency regulation under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979). If it is determined that 
this emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the Rules Docket (otherwise, an evaluation is 
not required). A copy of it, if filed, may be obtained from the Rules 
Docket.

    (e) Can I comply with this AD in any other way? You may use an 
alternative method of compliance or adjust the compliance time if:
    (1) Your alternative method of compliance provides an equivalent 
level of safety; and
    (2) The Manager, Chicago Aircraft Certification Office, approves 
your alternative. Send your request through an FAA Principal 
Maintenance Inspector, who may add comments and then send it to the

    Note: This AD applies to any aircraft with a tire installed as 
identified in paragraph (a) of this AD, regardless of whether the 
aircraft has been modified, altered, or repaired in the area subject 
to the requirements of this AD. For aircraft that have been 
modified, altered, or repaired so that the performance of the 
requirements of this AD is affected, the owner/operator must request 
approval for an alternative method of compliance in accordance with 
paragraph (e) of this AD. The request should include an assessment 
of the effect of the modification, alteration, or repair on the 
unsafe condition addressed by this AD; and, if you have not 
eliminated the unsafe condition, specific actions you propose to 
address it.

    (f) Where can I get information about any already-approved 
alternative methods of compliance? Contact Roy Boffo, Aerospace 
Engineer, FAA, Chicago Aircraft Certification Office, 2300 E. Devon

CFR 21.197 and 21.199) to operate your airplane to a location where 
you can accomplish the requirements of this AD.
