AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to certain McDonnell 

Douglas transport category airplanes. 

That AD currently requires, among other 

things, revision of an existing program 

of structural inspections. This new AD 

requires implementation of a program of 

structural inspections of baseline 

structure to detect and correct fatigue 

cracking in order to ensure the 

continued airworthiness of these 

airplanes as they approach the 

manufacturer’s original fatigue design 

life goal. This AD results from a 

significant number of these airplanes 

approaching or exceeding the design 

service goal on which the initial type 

certification approval was predicated. 

We are issuing this AD to detect and 

correct fatigue cracking that could 

compromise the structural integrity of 

these airplanes. 

DATES: This AD becomes effective 

November 29, 2006. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 29, 2006. 

The incorporation of a certain other 

publication, as listed in the regulations, 

was approved previously by the Director 

of the Federal Register as of July 24, 

1996 (61 FR 31009, June 19, 1996).

Discussion 

The FAA issued a notice of 

supplemental notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 96–13–03, amendment 

39–9671 (61 FR 31009, June 19, 1996). 

The existing AD applies to all 

McDonnell Douglas Model DC–9–10, 

–20, –30, –40, –50, and C–9 (military) 

series airplanes. (Since the issuance of 

that AD, the FAA has revised the 

applicability of the existing AD to 

identify model designations as 

published in the most recent type 

certificate data sheet for the affected 

models.) That supplemental NPRM was 

published in the Federal Register on 

March 7, 2006 (71 FR 11328). That 

supplemental NPRM proposed to 

require implementation of a program of 

structural inspections of baseline 

structure to detect and correct fatigue 

cracking in order to ensure the 

continued airworthiness of these 

airplanes as they approach the 

manufacturer’s original fatigue design 

life goal. 

mstockstill on PROD1PC61 with RULES

Federal Register / Vol. 71, No. 206 / Wednesday, October 25, 2006 / Rules and Regulations 62381 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the supplemental 

NPRM or on the determination of the 

cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

There are about 710 McDonnell 

Douglas transport category airplanes 

worldwide of the affected design. This 

AD will affect about 477 airplanes of 

U.S. registry, or 26 U.S. airline 

operators. 

The recurring inspection costs, as 

required by AD 96–13–03, take 362 

work hours per airplane, at an average 

labor rate of $65 per work hour. Based 

on these figures, the estimated cost of 

the currently required actions is 

$11,223,810, or $23,530 per airplane, 

per inspection cycle. 

The incorporation of the revised 

procedures in this AD action will 

require approximately 20 additional 

work hours per operator to accomplish, 

at an average labor rate of $65 per work 

hour. Based on these figures, the cost to 

the 26 affected U.S. operators to 

incorporate these revised procedures 

into the SID program is estimated to be 

$33,800, or $1,300 per operator. 

Additionally, the number of required 

work hours for each inspection (and the 

Supplemental Inspection Document 

(SID) program), as indicated above, is 

presented as if the accomplishment of 

those actions were to be conducted as 

‘‘stand alone’’ actions. However, in 

actual practice, these actions for the 

most part will be accomplished 

coincidently or in combination with 

normally scheduled airplane 

inspections and other maintenance 

program tasks. Further, any costs 

associated with special airplane 

scheduling are expected to be minimal. 

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.

Note 4: Requests for approval of any PSE 

repair that would affect the FAA-approved 

maintenance inspection program that is 

required by this AD should include a damage 

tolerance assessment for that PSE. 

New Requirements of This AD 

Revision of the Maintenance Inspection 

Program 

(h) Within 12 months after the effective 

date of this AD, incorporate a revision into 

the FAA-approved maintenance inspection 

program that provides for inspection(s) of the 

PSEs, in accordance with Boeing Report L26–

008, ‘‘DC–9 All Series, Supplemental 

Inspection Document (SID),’’ Volume I, 

Revision 6, dated November 2002. Unless 

otherwise specified, all further references in 

this AD to the ‘‘SID’’ are to Revision 6, dated 

November 2002. 

Non-Destructive Inspections (NDIs) 

(i) For all PSEs listed in Section 2 of 

Volume I of the SID, perform an NDI for 

fatigue cracking of each PSE in accordance 

with the NDI procedures specified in Section 

2 of Volume II, Revision 6, dated November 

2004, of the SID, at the times specified in 

paragraph (i)(1), (i)(2), or (i)(3) of this AD, as 

applicable. 

(1) For airplanes that have less than threequarters of the fatigue life threshold (3⁄4Nth) 

as of the effective date of the AD: Perform an 

NDI for fatigue cracking no earlier than onehalf of the threshold (1⁄2Nth) but prior to 

reaching three-quarters of the threshold 

(3⁄4Nth), or within 60 months after the 

effective date of this AD, whichever occurs 

later. Inspect again prior to reaching the 

threshold (Nth) or DNDI/2, whichever occurs 

later, but no earlier than (3⁄4Nth). Thereafter, 

after passing the threshold (Nth), repeat the 

inspection for that PSE at intervals not to 

exceed DNDI/2. 

(2) For airplanes that have reached or 

exceeded three-quarters of the fatigue life 

threshold (3⁄4Nth), but less than the threshold 

(Nth), as of the effective date of the AD: 

Perform an NDI prior to reaching the 

threshold (Nth), or within 18 months after the 

effective date of this AD, whichever occurs 

later. Thereafter, after passing the threshold 

(Nth), repeat the inspection for that PSE at 

intervals not to exceed DNDI/2. 

(3) For airplanes that have reached or 

exceeded the fatigue life threshold (Nth) as of 

the effective date of the AD: Perform an NDI 

within 18 months after the effective date of 

this AD. Thereafter, repeat the inspection for

Discrepant Findings 

(j) If any discrepancy (e.g., a PSE cannot be 

inspected as specified in Volume II of the SID 

or does not match rework, repair, or 

modification description in Volume I of the 

SID) is detected during any inspection 

required by paragraph (i) of this AD, 

accomplish the action specified in paragraph 

(j)(1) or (j)(2) of this AD, as applicable. 

(1) If a discrepancy is detected during any 

inspection performed prior to 3⁄4Nth or Nth: 

The area of the PSE affected by the 

discrepancy must be inspected prior to Nth or 

within 18 months of the discovery of the 

discrepancy, whichever is later, in 

accordance with a method approved by the 

Manager, Los Angeles ACO, FAA. 

(2) If a discrepancy is detected during any 

inspection performed after Nth: The area of 

the PSE affected by the discrepancy must be 

inspected prior to the accumulation of an 

additional DNDI/2, measured from the last 

non-discrepant inspection finding, or within 

18 months of the discovery of the 

mstockstill on PROD1PC61 with RULES

Federal Register / Vol. 71, No. 206 / Wednesday, October 25, 2006 / Rules and Regulations 62383 

discrepancy, whichever occurs later, in 

accordance with a method approved by the 

Manager of the Los Angeles ACO. 

Reporting Requirements 

(k) All negative, positive, or discrepant 

(discrepant finding examples are described in 

paragraph (j) of this AD) findings of the 

inspections accomplished under paragraph 

(i) of this AD must be reported to Boeing, at 

the times specified in, and in accordance 

with the instructions contained in, Section 4 

of Volume I, Revision 6, of the SID. 

Information collection requirements 

contained in this regulation have been 

approved by the Office of Management and 

Budget (OMB) under the provisions of the 

Paperwork Reduction Act (44 U.S.C. 3501 et 

seq.) and have been assigned OMB Control 

Number 2120–0056. 

Corrective Actions 

(l) Any cracked structure of a PSE detected 

during any inspection required by paragraph 

(i) of this AD must be repaired before further 

flight in accordance with a method approved 

by the Manager, Los Angles ACO, or by using 

a method approved in accordance with 

procedures specified in paragraph (p) of this 

AD. Accomplish follow-on actions described 

in paragraphs (l)(1), (l)(2), and (l)(3) of this 

AD, at the times specified. 

(1) Within 18 months after repair, perform 

a damage tolerance assessment (DTA) that 

defines the threshold for inspection of the 

repair and submit the assessment for 

approval. 

(2) Before reaching 75% of the repair 

threshold as determined in paragraph (l)(1) of 

this AD, submit the inspection methods and 

repetitive inspection intervals for the repair 

for approval. 

(3) Before the repair threshold, as 

determined in paragraph (l)(1) of this AD, 

incorporate the inspection method and 

repetitive inspection intervals into the FAAapproved structural maintenance or 

inspection program for the airplane. 

Note 6: For the purposes of this AD, we 

anticipate that submissions of the DTA of the 

repair, if acceptable, should be approved 

within six months after submission. 

Note 7: Advisory Circular AC 25.1529–1, 

‘‘Instructions for Continued Airworthiness of 

Structural Repairs on Transport Airplanes,’’

dated August 1, 1991, is considered to be 

additional guidance concerning the approval 

of repairs to PSEs. 

Inspection for Transferred Airplanes 

(m) Before any airplane that has exceeded 

the fatigue life threshold (Nth) can be added 

to an air carrier’s operations specifications, a 

program for the accomplishment of the 

inspections required by this AD must be 

established per paragraph (m)(1) or (m)(2) of 

this AD, as applicable. 

(1) For airplanes that have been inspected 

in accordance with this AD, the inspection of 

each PSE must be accomplished by the new 

operator in accordance with the previous 

operator’s schedule and inspection method, 

or the new operator’s schedule and 

inspection method, at whichever time would 

result in the earlier accomplishment date for 

that PSE inspection. The compliance time for 

accomplishment of this inspection must be 

measured from the last inspection 

accomplished by the previous operator. After 

each inspection has been performed once, 

each subsequent inspection must be 

performed in accordance with the new 

operator’s schedule and inspection method. 

(2) For airplanes that have not been 

inspected in accordance with this AD, the 

inspection of each PSE required by this AD 

must be accomplished either prior to adding 

the airplane to the air carrier’s operations 

specification, or in accordance with a 

schedule and an inspection method approved 

by the Manager, Los Angeles ACO. After each 

inspection has been performed once, each 

subsequent inspection must be performed per 

the new operator’s schedule. 

Inspections Accomplished Before the 

Effective Date of This AD 

(n) Inspections accomplished prior to the 

effective date of this AD in accordance with 

Boeing Report No. L26–008, ‘‘DC–9 All Series 

Supplemental Inspection Document (SID),’’

Volume I, Revision 6, dated November 2002, 

are acceptable for compliance with the 

requirements of paragraph (i) of this AD. 

Acceptable for Compliance 

(o) Boeing Report MDC 91K0263, ‘‘DC–9/ 

MD–80 Aging Aircraft Repair Assessment 

Program Document,’’ Revision 1, dated 

October 2000, provides inspection/ 

replacement programs for certain repairs to 

the fuselage pressure shell. These repairs and 

inspection/replacement programs are 

considered acceptable for compliance with 

the requirements of paragraphs (i), (l), and 

(m) of this AD for repairs subject to that 

document. 

Alternative Methods of Compliance 

(AMOCs) 

(p)(1) The Manager, Los Angles ACO, has 

the authority to approve AMOCs for this AD, 

if requested in accordance with the 

procedures found in 14 CFR 39.19. 

(2) Before using any AMOC approved in

Memphis/Shelby County Area Second 

10-Year Maintenance Plan for the 

Carbon Monoxide National Ambient Air 

Quality Standard 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Direct final rule. 

SUMMARY: EPA is approving a revision to 

the Tennessee State Implementation 

Plan (SIP) submitted in final form on 

May 17, 2006. The SIP revision provides 

the second 10-year maintenance plan for 

the Memphis/Shelby County Carbon 

Monoxide (CO) Maintenance Area. The 

second 10-year maintenance plan 

includes a new motor vehicle emission 

budget (MVEB) for CO for the year 2017. 

EPA is approving this SIP revision, 

including the new 2017 MVEB for CO, 

because it satisfies the requirement of 

the Clean Air Act (CAA) for the second 

10-year maintenance plan for the 

Memphis/Shelby County Area. 

In addition, in this rulemaking, EPA 

is providing information on its 

transportation conformity adequacy 

determination for the new MVEB for the 

year 2017 that is contained in the 

second 10-year CO maintenance plan for 

the Memphis/Shelby County Area. 

DATES: This rule is effective on 

December 26, 2006 without further 

notice, unless EPA receives adverse 

comments by November 24, 2006. If we 

receive such comments, we will publish 

a timely withdrawal in the Federal 

Register to notify the public that this 

direct final rule will not take effect.
