Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain aviation tires installed on various transport category airplanes. That NPRM was published in the Federal Register on May 3, 2006 (71 FR 25987). That NPRM proposed to require a one-time inspection of the nosewheel E:\FR\FM\06SER1.SGM 06SER1 52424 Federal Register / Vol. 71, No. 172 / Wednesday, September 6, 2006 / Rules and Regulations tires to determine if they are within a designated serial number range, and replacement if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the NPRM Two commenters, both private citizens, state that they support the NPRM. jlentini on PROD1PC65 with RULES Requests To Revise Cost Estimate The same commenters request that we revise the cost estimate in the NPRM. Both commenters state that in their experience the inspection to determine the serial number of the tire would take much less time than the one hour given for that action in the NPRM. The commenters state that the inspection should take only 10 to 15 minutes. One commenter points out that the removal and replacement of the affected tires would take 1 to 2 hours, depending on the current status of the airplane and other variables. We partially agree. We agree that the inspection may take less than 1 hour. We disagree that it is necessary to change the cost estimate for the inspection to 10 to 15 minutes rather than 1 hour. We provide these estimates in order to give airplane operators notice of the costs they are likely to incur to do the actions specifically required by the AD. To account for the worst-case cost for each operator, we generally round dollar and hour figures to the next-highest value. We also disagree with the request to change the cost estimate to include the replacement cost. The replacement is an ‘‘on condition’’ action, and may or may not be required for a given airplane. The cost figures discussed in NPRMs represent only the time necessary to perform the specific actions actually required by the AD; in this case, the inspection. These figures also do not typically include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions. We have not changed the final rule in this regard. Requests To Revise Compliance Time The same commenters both request that we revise the compliance time for doing the inspection from 60 days to 30 days. The commenters point out that Goodyear Aviation Service Bulletin SB– 2005–32–004, Revision 5, dated December 22, 2005 (referred to in the VerDate Aug<31>2005 16:42 Sep 05, 2006 Jkt 205001 NPRM as the appropriate source of service information for accomplishing the actions), recommends a compliance time of 14 days, which leads one commenter to believe that this is a serious problem and should be a safety concern for Gulfstream and Bombardier owners. One commenter says that even though the NPRM states that most operators have already complied with the service bulletin, that does not mean it is time to ease up on the others’ safety. The other commenter points out that it doesn’t take long to inspect the tire and determine the serial number. The commenters both cite serious aviation accidents related to blown tires, and state that the potential serious consequences also justify a shorter compliance time. We acknowledge the commenters’ concerns. However, we do not agree with the request to revise the compliance time. In developing an appropriate compliance time, we considered the safety implications, parts availability, and normal maintenance schedules. Further, the manufacturer agreed with the proposed compliance time, and now reports that of the 142 affected tires, 25 have been returned in accordance with the instructions in Goodyear Aviation Service Bulletin SB– 2005–32–004, Revision 5. We also note that Gulfstream reports 90 percent compliance and Bombardier reports 82 percent compliance as of the closing date for comments on the NPRM. In addition, if we were to shorten the compliance time, it would be necessary for us to issue a supplemental NPRM to solicit additional public comment on the new, shorter compliance time. The additional time for comment would add at least 45 days to the total time it will take for the NPRM to become a final rule and thereby add 45 days more before the tires would be required to be inspected. Therefore, we have not changed the final rule in this regard. Explanation of Additional Service Information Bombardier has informed us that it has issued two service bulletins that give additional service information for identifying the affected serial numbers and replacing the tires as applicable. We have reviewed and added the following service bulletins to Note 1 of the final rule: Bombardier Alert Service Bulletins A700–32–019 and A700–1A11–32–007, both dated November 2, 2005. Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. 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 AD will affect about 1,035 Gulfstream airplanes, and about 104 Bombardier airplanes of U.S. registry. The inspection for the affected serial numbers takes 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 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 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. 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 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.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain aviation tires installed on various transport category 
airplanes. This AD requires a one-time inspection of the nosewheel 
tires to determine if they are within a designated serial number range, 
and replacement if necessary. 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 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: This AD becomes effective October 11, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of October 11, 
2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at https://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain aviation tires 
installed on various transport category airplanes. That NPRM was 
published in the Federal Register on May 3, 2006 (71 FR 25987). That 
NPRM proposed to require a one-time inspection of the nosewheel

[[Page 52424]]

tires to determine if they are within a designated serial number range, 
and replacement if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Support for the NPRM

    Two commenters, both private citizens, state that they support the 
NPRM.

Requests To Revise Cost Estimate

    The same commenters request that we revise the cost estimate in the 
NPRM. Both commenters state that in their experience the inspection to 
determine the serial number of the tire would take much less time than 
the one hour given for that action in the NPRM. The commenters state 
that the inspection should take only 10 to 15 minutes. One commenter 
points out that the removal and replacement of the affected tires would 
take 1 to 2 hours, depending on the current status of the airplane and 
other variables.
    We partially agree. We agree that the inspection may take less than 
1 hour. We disagree that it is necessary to change the cost estimate 
for the inspection to 10 to 15 minutes rather than 1 hour. We provide 
these estimates in order to give airplane operators notice of the costs 
they are likely to incur to do the actions specifically required by the 
AD. To account for the worst-case cost for each operator, we generally 
round dollar and hour figures to the next-highest value.
    We also disagree with the request to change the cost estimate to 
include the replacement cost. The replacement is an ``on condition'' 
action, and may or may not be required for a given airplane. The cost 
figures discussed in NPRMs represent only the time necessary to perform 
the specific actions actually required by the AD; in this case, the 
inspection. These figures also do not typically include incidental 
costs, such as the time required to gain access and close up, planning 
time, or time necessitated by other administrative actions.
    We have not changed the final rule in this regard.

Requests To Revise Compliance Time

    The same commenters both request that we revise the compliance time 
for doing the inspection from 60 days to 30 days. The commenters point 
out that Goodyear Aviation Service Bulletin SB-2005-32-004, Revision 5, 
dated December 22, 2005 (referred to in the NPRM as the appropriate 
source of service information for accomplishing the actions), 
recommends a compliance time of 14 days, which leads one commenter to 
believe that this is a serious problem and should be a safety concern 
for Gulfstream and Bombardier owners. One commenter says that even 
though the NPRM states that most operators have already complied with 
the service bulletin, that does not mean it is time to ease up on the 
others' safety. The other commenter points out that it doesn't take 
long to inspect the tire and determine the serial number. The 
commenters both cite serious aviation accidents related to blown tires, 
and state that the potential serious consequences also justify a 
shorter compliance time.
    We acknowledge the commenters' concerns. However, we do not agree 
with the request to revise the compliance time. In developing an 
appropriate compliance time, we considered the safety implications, 
parts availability, and normal maintenance schedules. Further, the 
manufacturer agreed with the proposed compliance time, and now reports 
that of the 142 affected tires, 25 have been returned in accordance 
with the instructions in Goodyear Aviation Service Bulletin SB-2005-32-
004, Revision 5. We also note that Gulfstream reports 90 percent 
compliance and Bombardier reports 82 percent compliance as of the 
closing date for comments on the NPRM. In addition, if we were to 
shorten the compliance time, it would be necessary for us to issue a 
supplemental NPRM to solicit additional public comment on the new, 
shorter compliance time. The additional time for comment would add at 
least 45 days to the total time it will take for the NPRM to become a 
final rule and thereby add 45 days more before the tires would be 
required to be inspected. Therefore, we have not changed the final rule 
in this regard.

Explanation of Additional Service Information

    Bombardier has informed us that it has issued two service bulletins 
that give additional service information for identifying the affected 
serial numbers and replacing the tires as applicable. We have reviewed 
and added the following service bulletins to Note 1 of the final rule: 
Bombardier Alert Service Bulletins A700-32-019 and A700-1A11-32-007, 
both dated November 2, 2005.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the change described previously. 
We have determined that this change will neither increase the economic 
burden on any operator nor increase the scope of the AD.

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 AD 
will affect about 1,035 Gulfstream airplanes, and about 104 Bombardier 
airplanes of U.S. registry. The inspection for the affected serial 
numbers takes 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 
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 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.
    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 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

2006-18-08 Transport Category Airplanes: Amendment 39-14746. Docket 
No. FAA-2006-24667; Directorate Identifier 2006-NM-009-AD.

Effective Date

    (a) This AD becomes effective October 11, 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, G-IV-X, G-V, and G-V-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 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.

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 (S/N), and Replacement

    (f) Within 60 days after the effective date of this AD: Inspect 
the nosewheel tires to determine whether an affected 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: Bombardier Alert Service Bulletins A700-32-019 and A700-
1A11-32-007, both dated November 2, 2005; and the Gulfstream alert
