AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 727–100 and 727–200 

series airplanes. This AD requires 

repetitive internal and external high 

frequency eddy current, mid frequency 

eddy current, low frequency eddy 

current, and magneto optic imaging 

inspections to detect cracks, corrosion, 

delamination, and materials loss in the 

lower fastener row of the lower skin and 

the upper fastener row of the upper 

skin, and corrective actions if necessary. 

This AD results from a report of 

decompression in a Boeing Model 737 

airplane at flight level 290. We are 

issuing this AD to detect and correct 

scratches and excessive reduction in 

material thickness from excessive blendout or corrosion, which could lead to 

premature cracking in the lap joint. 

Such cracking could adversely affect the 

structural integrity of the airplane. 

DATES: This AD is effective April 28, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 28, 2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Boeing Model 727–100 and 727– 

200 series airplanes. That NPRM was 

published in the Federal Register on 

October 17, 2008 (73 FR 61747). That 

NPRM proposed to require repetitive 

internal and external high frequency 

eddy current, mid frequency eddy 

mstockstill on PROD1PC66 with RULES

12242 Federal Register / Vol. 74, No. 55 / Tuesday, March 24, 2009 / Rules and Regulations 

current, low frequency eddy current, 

and magneto optic imaging inspections 

to detect cracks, corrosion, 

delamination, and materials loss in the 

lower fastener row of the lower skin and 

the upper fastener row of the upper 

skin, and corrective actions if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. The 

commenter, Boeing, supports the 

NPRM. 

Clarification of Paragraph (f)(1) of This 

AD 

We have revised paragraph (f)(1) of 

this AD to clarify the exception to the 

compliance times in Boeing Alert 

Service Bulletin 727–53A0223, dated 

March 28, 2002. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 73 

airplanes of U.S. registry. We also 

estimate that it would take 56 work 

hours per product to comply with this 

AD. The average labor rate is $80 per 

work hour. Based on these figures, we 

estimate the cost of this AD to the U.S. 

operators to be $327,040, or $4,480 per 

product, per inspection cycle. 

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 

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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2009–06–10 Boeing: Amendment 39–15846. 

Docket No. FAA–2008–1103; Directorate 

Identifier 2008–NM–048–AD. 

Effective Date 

(a) This airworthiness directive (AD) is 

effective April 28, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Boeing Model 727– 

100 and 727–200 series airplanes, certificated 

in any category; as identified in Boeing Alert 

Service Bulletin 727–53A0223, dated March 

28, 2002. 

Unsafe Condition 

(d) This AD results from a report of 

decompression in a Boeing Model 737 

airplane at flight level 290. We are issuing 

this AD to detect and correct scratches and 

excessive reduction in material thickness 

from excessive blend-out or corrosion, which 

could lead to premature cracking in the lap 

joint. Such cracking could adversely affect 

the structural integrity of the airplane. 

Compliance 

(e) Comply with this AD within the 

compliance times specified, unless already 

done. 

Inspections and Corrective Actions 

(f) Except as provided by paragraphs (f)(1), 

(f)(2), and (f)(3) of this AD: At the applicable 

compliance times and repeat intervals listed 

in paragraph 1.E., ‘‘Compliance,’’ of Boeing 

Alert Service Bulletin 727–53A0223, dated 

March 28, 2002 (‘‘the service bulletin’’), do 

repetitive internal and external high 

frequency eddy current, mid frequency eddy 

current, low frequency eddy current, and 

magneto optic imaging inspections to detect 

cracks, corrosion, delamination, and 

materials loss in the lower fastener row of the 

lower skin and the upper fastener row of the 

upper skin, and corrective actions by 

accomplishing all the applicable actions 

specified in the Accomplishment 

Instructions of the service bulletin. The 

applicable corrective actions must be done 

before further flight. 

(1) Paragraph 1.E. of Boeing Alert Service 

Bulletin 727–53A0223, dated March 28, 

2002, has the table column titled, ‘‘Airplane 

Flight Cycles at time of SB release.’’ While 

the service bulletin refers to the flight cycles 

accumulated on the airplane at the ‘‘time of 

SB release,’’ this AD specifies the flight 

cycles accumulated on the airplane ‘‘as of the 

effective date of this AD.’’ 

(2) Where paragraph 1.E., ‘‘Compliance,’’ of 

the service bulletin specifies ‘‘Initial 

Inspection Threshold From SB Rel Upper 

and Lower Skin,’’ this AD requires 

compliance within the specified compliance 

times after the effective date of this AD. 

(3) Where paragraph 1.E., ‘‘Compliance,’’ of 

the service bulletin specifies ‘‘Repeat every 

* * *,’’ this AD requires compliance at 

intervals not to exceed the specified flight 

cycles or years. 

No Reporting 

(g) Although Boeing Alert Service Bulletin 

727–53A0223, dated March 28, 2002, 

specifies to submit information to the 

manufacturer, this AD does not include that 

requirement. 

Alternative Methods of Compliance 

(AMOCs) 

(h)(1) The Manager, Seattle Aircraft 

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. Send information to ATTN:

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 767–200 and 767–300 

series airplanes. This AD requires 

detailed inspections of the aft pressure 

bulkhead for damage, mid-frequency 

eddy current (MFEC) and low frequency 

eddy current (LFEC) inspections of 

radial web lap splices, tear strap splices, 

and super tear strap splices for cracking, 

and corrective actions if necessary. This 

AD results from analysis that indicates 

fatigue cracks of the web lap splice, tear 

strap splice, or super tear strap splice of 

the aft bulkhead are expected to occur 

on certain Boeing Model 767–200 and 

767–300 series airplanes. We are issuing 

this AD to detect and correct fatigue 

cracks of the aft pressure bulkhead, 

which could result in rapid 

decompression of the passenger 

compartment and possible damage or 

interference with airplane control 

systems that penetrate the bulkhead, 

and consequent loss of controllability of 

the airplane. 

DATES: This AD is effective April 28, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 28, 2009.

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Boeing Model 767–200 and 767–

published in the Federal Register on 

August 21, 2008 (73 FR 49366). That 

NPRM proposed to require detailed 

inspections of the aft pressure bulkhead 

for damage, mid-frequency eddy current 

(MFEC) and low frequency eddy current 

(LFEC) inspections of radial web lap 

splices, tear strap splices, and super tear 

strap splices for cracking, and corrective 

actions if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Refer to AD 2003–18–10 

Boeing and United Airlines ask that 

we refer to AD 2003–18–10, amendment 

39–13301 (68 FR 53503, September 11, 

2003) in the AD. 

Boeing states that AD 2003–18–10 

requires a revision of the Boeing 767 

Maintenance Planning Data (MPD) 

Document D622T001–9 to incorporate 

the October 2002 revision, and 

Appendix B of the Boeing 767 MPD 

Document D622T001 to incorporate the 

December 2002 revision, for Model 767 

line numbers 1–895. Boeing adds that 

the inspection requirements of Boeing 

Alert Service Bulletin 767–53A0147, 

dated August 16, 2007, supersede the 

Boeing 767 MPD Document D622T001– 

9 and Document D622T001, Appendix 

B, inspections for Structural Significant 

Items (SSI) 53–80–I01B, C, D, and E. 

Boeing concludes that the NPRM affects 

the requirements of AD 2003–18–10 and 

asks that a reference to that AD be 

added to the ‘‘Affected ADs’’ paragraph 

of the NPRM. 

United Airlines (UAL) states that a 

reference to AD 2003–18–10 should be 

included because paragraph 1.F. of 

Boeing Alert Service Bulletin 767– 

53A0147, dated August 16, 2007, states 

that the Accomplishment Instructions 

‘‘are approved as an alternative method 

of compliance (AMOC) to the 

inspections of SSI 53–80–I01B, C, D, 

and E of Boeing 767 MPD Document 

D622T001–9 and Appendix B of Boeing 

767 MPD Document D622T001 as 

required by paragraph (d) of 

Airworthiness Directive (AD) 2003–18– 

10.’’ In addition, due to the AD-related 

SSIs, UAL states that the NPRM should 

include the SSI numbers specified in 

Boeing Alert Service Bulletin 767– 

53A0147, dated August 16, 2007.
