ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas transport category airplanes. This AD requires an initial ultrasonic inspection for cracks of the studbolts of the inboard and outboard hinge fittings of the left and right outboard flaps of the wings. Based on the inspection results, this AD also requires doing repetitive ultrasonic inspections, replacing upper and/or lower studbolts with new or serviceable studbolts, doing a detailed inspection for corrosion of the upper studbolts, doing a magnetic particle inspection for E:\FR\FM\09FER1.SGM 09FER1 6670 Federal Register / Vol. 71, No. 27 / Thursday, February 9, 2006 / Rules and Regulations part 39 to include an AD that would apply to certain McDonnell Douglas Model DC–10–10, DC–10–10F, DC–10– 15, DC–10–30, DC–10–30F (KC–10A and KDC–10), DC–10–40, DC–10–40F, MD–10–10F, MD–10–30F, MD–11, and MD–11F airplanes. That NPRM was published in the Federal Register on September 22, 2005 (70 FR 55598). That NPRM proposed to require an initial ultrasonic inspection for cracks of the studbolts of the inboard and outboard hinge fittings of the left and right outboard flaps of the wings. Based on the inspection results, that NPRM also proposed to require doing repetitive ultrasonic inspections, replacing upper and/or lower studbolts with new or serviceable studbolts, doing a detailed inspection for corrosion of the upper studbolts, doing a magnetic particle inspection for cracks of studbolts, and changing the protection treatment; as applicable. cracks of studbolts, and changing the protection treatment; as applicable. This AD results from reports of corrosion and failures of the upper and lower studbolts of the outboard flaps inboard and outboard hinge fittings. We are issuing this AD to prevent corrosion and subsequent cracking of studbolts, which could result in failure of the flap hinge fittings and their possible separation from the wing rear spar, and consequent reduced controllability of the airplane. DATES: This AD becomes effective March 16, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of March 16, 2006.

FOR FURTHER INFORMATION CONTACT: Maureen Moreland, Aerospace Engineer, Airframe Branch, ANM–120L, FAA, Los Angeles Aircraft Certification Office, 3960 Paramount Boulevard, Lakewood, California 90712–4137; telephone (562) 627–5238; fax (562) 627–5210. SUPPLEMENTARY INFORMATION: Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. 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 Request To Consider Parts Availability One commenter requests that we consider parts availability before setting an effective date for the AD. The commenter states that there are no kits available to do the proposed replacement. The commenter also states that most quantities of studbolts are minimal (less than 50 available) with additional orders coming in from suppliers in the first half of 2006. We agree to consider parts availability, but do not agree that there is a shortage of parts. The AD specifies several options for continued operation with existing studbolts that are found not to be cracked. Options include installing new bolts with increased corrosion protections; treating existing studbolts with corrosion protection in accordance with a method approved by us; and replacing the studbolts with equivalent studbolts with follow-on repetitive inspections. In addition, the airplane manufacturer has informed us that they have developed corrosion protection methodologies and will pursue approval from us once the final rule is issued. We will support this effort. The airplane manufacturer also has informed us that they are scheduled to receive studbolts in March of 2006 to support the required replacement of failed studbolts. For operators that initiate a program to replace all the studbolts as terminating action, the airplane manufacturer recommends placing a specific purchase order for the part numbers and quantities of studbolts required, along with a time frame that supports their replacement program. In light of these findings, we have determined that no change to the final rule is necessary. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Clarification of Replacement In paragraph (j)(4) of the NPRM, we inadvertently omitted the reference to the service bulletin. We have revised that paragraph to include the phrase ‘‘in accordance with the service bulletin.’’ 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 594 airplanes of the affected design in the worldwide fleet. This AD will affect about 297 U.S.registered Model DC–10–10, DC–10– 10F, DC–10–15, DC–10–30, DC–10–30F (KC–10A and KDC–10), DC–10–40, DC– 10–40F, MD–10–10F, and MD–10–30F airplanes; and 69 Model MD–11 and –11F airplanes. cprice-sewell on PROD1PC66 with RULES ESTIMATED COSTS FOR REQUIRED ACTIONS Action Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.-registered airplanes Fleet cost Initial ultrasonic inspection ...................... 16 $65 None ....................... $1,040 366 $380,640 VerDate Aug<31>2005 12:39 Feb 08, 2006 Jkt 208001 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 E:\FR\FM\09FER1.SGM 09FER1 Federal Register / Vol. 71, No. 27 / Thursday, February 9, 2006 / Rules and Regulations 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.

ACTION: Final rule; request for comments. cprice-sewell on PROD1PC66 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Rolls Royce plc (RR) RB211 Trent 500 series turbofan engines. This AD requires initial and repetitive borescope inspections of the high pressure-andintermediate pressure (HP–IP) turbine oil vent tubes and bearing chambers for coking and carbon buildup and VerDate Aug<31>2005 12:39 Feb 08, 2006 Jkt 208001 replacing the vent tubes if necessary. This AD results from a report of an RB211 Trent 700 series engine that experienced a disk shaft separation, overspeed of the IP turbine rotor, and multiple blade release of IP turbine blades. Since the design arrangement in the Trent 500 series engines is similar to that of the Trent 700 series engines, the same failure could occur in the Trent 500 series engines. We are issuing this AD to prevent internal oil fires caused by coking and carbon buildup, that could result in uncontained engine failure and damage to the airplane.

SUPPLEMENTARY INFORMATION: The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom (UK) recently notified us that an unsafe condition might exist on RR RB211 Trent 500 Series turbofan engines. The CAA advises that a previous service incident in a Trent 700 engine indicates that carbon restriction in the vent tube can cause overpressurization of the HP–IP bearing chamber leading to oil ejection from the PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 6673 rear of the chamber. If this oil spray ignites, the fire can cause an IPT shaft failure, leading to overspeed and uncontained failure of the IPT disc. Since the design arrangement in the Trent 500 engines is similar to that of the Trent 700 engines, the same failure could occur in the Trent 500 series engines. We are issuing this AD to prevent internal oil fires caused by coking and carbon buildup, that could result in uncontained engine failure and damage to the airplane. Relevant Service Information We have reviewed and approved the technical contents of RR Alert Service Bulletin (ASB) RB.211–72–AE836, Revision 1, dated October 5, 2005. That ASB describes procedures for initial and repetitive borescope inspection and assessment of the HP–IP turbine oil vent tubes and bearing chamber. The CAA classified this service bulletin as mandatory and issued AD No. G–2005– 0029, dated October 4, 2005, in order to ensure the airworthiness of these RR Trent 500 series engines in the U.K. Bilateral Airworthiness Agreement These RB211 Trent 500 series turbofan engines are manufactured in the U.K. and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, the CAA kept the FAA informed of the situation described above. We have examined the findings of the CAA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. FAA’s Determination and Requirements of This AD Although no airplanes that are registered in the United States use these engines, the possibility exists that the engines could be used on airplanes that are registered in the United States in the future. The unsafe condition described previously is likely to exist or develop on other RR RB211 Trent 500 series turbofan engines of the same type design. This AD requires initial and repetitive borescope inspections of the HP–IP turbine bearing oil vent tubes and bearing chambers for coking and carbon buildup; and replacement of the tubes if necessary. We are issuing this AD to prevent internal oil fires from coking and carbon buildup that could cause uncontained engine failure and damage to the E:\FR\FM\09FER1.SGM 09FER1

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain McDonnell Douglas transport category airplanes. This AD 
requires an initial ultrasonic inspection for cracks of the studbolts 
of the inboard and outboard hinge fittings of the left and right 
outboard flaps of the wings. Based on the inspection results, this AD 
also requires doing repetitive ultrasonic inspections, replacing upper 
and/or lower studbolts with new or serviceable studbolts, doing a 
detailed inspection for corrosion of the upper studbolts, doing a 
magnetic particle inspection for

[[Page 6670]]

cracks of studbolts, and changing the protection treatment; as 
applicable. This AD results from reports of corrosion and failures of 
the upper and lower studbolts of the outboard flaps inboard and 
outboard hinge fittings. We are issuing this AD to prevent corrosion 
and subsequent cracking of studbolts, which could result in failure of 
the flap hinge fittings and their possible separation from the wing 
rear spar, and consequent reduced controllability of the airplane.

DATES: This AD becomes effective March 16, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 16, 
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 McDonnell 
Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-
10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and 
MD-11F airplanes. That NPRM was published in the Federal Register on 
September 22, 2005 (70 FR 55598). That NPRM proposed to require an 
initial ultrasonic inspection for cracks of the studbolts of the 
inboard and outboard hinge fittings of the left and right outboard 
flaps of the wings. Based on the inspection results, that NPRM also 
proposed to require doing repetitive ultrasonic inspections, replacing 
upper and/or lower studbolts with new or serviceable studbolts, doing a 
detailed inspection for corrosion of the upper studbolts, doing a 
magnetic particle inspection for cracks of studbolts, and changing the 
protection treatment; as applicable.

Comments

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

Request To Consider Parts Availability

    One commenter requests that we consider parts availability before 
setting an effective date for the AD. The commenter states that there 
are no kits available to do the proposed replacement. The commenter 
also states that most quantities of studbolts are minimal (less than 50 
available) with additional orders coming in from suppliers in the first 
half of 2006.
    We agree to consider parts availability, but do not agree that 
there is a shortage of parts. The AD specifies several options for 
continued operation with existing studbolts that are found not to be 
cracked. Options include installing new bolts with increased corrosion 
protections; treating existing studbolts with corrosion protection in 
accordance with a method approved by us; and replacing the studbolts 
with equivalent studbolts with follow-on repetitive inspections.
    In addition, the airplane manufacturer has informed us that they 
have developed corrosion protection methodologies and will pursue 
approval from us once the final rule is issued. We will support this 
effort. The airplane manufacturer also has informed us that they are 
scheduled to receive studbolts in March of 2006 to support the required 
replacement of failed studbolts. For operators that initiate a program 
to replace all the studbolts as terminating action, the airplane 
manufacturer recommends placing a specific purchase order for the part 
numbers and quantities of studbolts required, along with a time frame 
that supports their replacement program.
    In light of these findings, we have determined that no change to 
the final rule is necessary.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Clarification of Replacement

    In paragraph (j)(4) of the NPRM, we inadvertently omitted the 
reference to the service bulletin. We have revised that paragraph to 
include the phrase ``in accordance with the service bulletin.''

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 594 airplanes of the affected design in the 
worldwide fleet. This AD will affect about 297 U.S.-registered Model 
DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), 
DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F airplanes; and 69 Model 
MD-11 and -11F airplanes.

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.
