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.

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. rmajette on PROD1PC67 with PROPOSALS 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.

GV, Number 24. G500, Number 5; and G550, Number 5. 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 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety.

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.

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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

Transport Category Airplanes: Docket No. FAA-2006-24667; Directorate 
Identifier 2006-NM-009-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by June 19, 
2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Goodyear Aviation Tires, Part Number 
217K22-1, identified in Goodyear Aviation Service Bulletin SB-2005-
32-004, Revision 5, dated December 22, 2005; installed on various 
transport category airplanes, certificated in any category, 
including but not limited to Bombardier Model BD-700-1A10 and BD-
700-1A11 airplanes; and Gulfstream Model G-1159, G-1159A, G-1159B, 
G-IV, GIV-X, GV, and GV-SP series airplanes.

Unsafe Condition

    (d) This AD results from reports of tread separations and tread-
area bulges on the nosewheel tires. We are issuing this AD to 
prevent tread separation from nosewheel tires 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.

[[Page 25989]]

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspection to Determine Serial Number, and Replacement

    (f) Within 60 days after the effective date of this AD: Inspect 
the nosewheel tires to determine whether an affected serial number 
(S/N) is installed, in accordance with the Accomplishment 
Instructions of Goodyear Aviation Service Bulletin SB-2005-32-004, 
Revision 5, dated December 22, 2005; and, except as provided by 
paragraph (g) of this AD, replace any tire with an affected S/N 
before further flight in accordance with the Accomplishment 
Instructions of the service bulletin.

    Note 1: The Gulfstream Alert Customer Bulletins listed in Table 
1 of this AD are additional sources of service information for 
identifying the affected serial numbers and replacing the tires as 
applicable.

Special Flight Permit

    (g) A special flight permit may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) for one flight to operate the airplane to a 
location where the requirements of this AD can be accomplished, 
provided no bulge is present on the tire with the affected S/N.

Parts Installation

    (h) After the effective date of this AD, no person may install 
on any airplane a nosewheel tire that has an S/N in the affected 
range identified in the Accomplishment Instructions of Goodyear 
Aviation Service Bulletin SB-2005-32-004, Revision 5, dated December 
22, 2005.

No Parts Return

    (i) Although Goodyear Aviation Service Bulletin SB-2005-32-004, 
Revision 5, dated December 22, 2005, specifies to return tires to 
the manufacturer, this AD does not require that action.
