AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 747–100, 747–100B, 747– 

100B SUD, 747–200B, 747–200C, 747– 

200F, 747–300, 747–400, 747SR, and 

747SP series airplanes. This AD requires 

inspecting for skin cracks at the shear 

tie end fastener locations of the fuselage 

frames, and repairing cracks if 

necessary. This AD results from a widespread fatigue damage assessment of 

Model 747 airplanes. We are issuing this 

AD to detect and correct cracks in the 

fuselage skin that can propagate and 

grow, resulting in a loss of structural 

integrity and a sudden decompression 

of the airplane during flight. 

DATES: This AD is effective April 20, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 20, 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 747–100, 747– 

100B, 747–100B SUD, 747–200B, 747– 

200C, 747–200F, 747–300, 747–400, 

747SR, and 747SP series airplanes. That 

NPRM was published in the Federal 

Register on October 8, 2008 (73 FR 

58901). That NPRM proposed to require 

inspecting for skin cracks at the shear 

tie end fastener locations of the fuselage 

frames, and repairing cracks if 

necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Boeing concurs with the contents of the 

NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments 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 147 

airplanes of U.S. registry. We also 

estimate that it takes 30 work-hours for 

the detailed inspection, or 49 work 

hours for the HFEC inspection, 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 $352,800 or $576,240, or $2,400 or 

$3,920 per product. 

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 

11014 Federal Register / Vol. 74, No. 49 / Monday, March 16, 2009 / Rules and 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: 

2009–06–02 Boeing: Amendment 39–15838. 

Docket No. FAA–2008–1072; Directorate 

Identifier 2008–NM–109–AD. 

Effective Date 

(a) This airworthiness directive (AD) is 

effective April 20, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Boeing Model 747– 

100, 747–100B, 747–100B SUD, 747–200B, 

747–200C, 747–200F, 747–300, 747–400, 

747SR, and 747SP series airplanes, 

certificated in any category; as identified in 

Boeing Alert Service Bulletin 747–53A2682, 

dated May 8, 2008. 

Unsafe Condition 

(d) This AD results from a wide-spread 

fatigue damage assessment of Model 747 

airplanes. We are issuing this AD to detect 

and correct cracks in the fuselage skin that 

can propagate and grow, resulting in a loss 

of structural integrity and sudden 

decompression of the airplane during flight. 

Compliance 

(e) Comply with this AD within the 

compliance times specified, unless already 

done. 

Inspections/Repair 

(f) Except as provided by paragraphs (g) 

and (h) of this AD: At the applicable 

compliance times specified in paragraph 1.E. 

of Boeing Alert Service Bulletin 747– 

53A2682, dated May 8, 2008 (‘‘the service 

bulletin’’), do an external detailed inspection 

or external high frequency eddy current 

inspection for skin cracks at the shear tie end 

fastener locations of the fuselage frames, and 

repair any skin cracks before further flight, by 

accomplishing all of the applicable actions 

specified in the Accomplishment 

Instructions of the service bulletin. Repeat 

the applicable inspection thereafter at the 

applicable interval specified in paragraph 

1.E. of the service bulletin. 

Exceptions to the Service Bulletin 

(g) Where paragraph 1.E. of Boeing Alert 

Service Bulletin 747–53A2682, dated May 8, 

2008, specifies counting the compliance time 

from ‘‘* * * the date on this service 

bulletin,’’ this AD requires counting the 

compliance time from the effective date of 

this AD. 

(h) If any crack is found in a structural 

repair manual skin repair during any 

inspection required by paragraph (f) of this 

AD, and Boeing Alert Service Bulletin 747– 

53A2682, dated May 8, 2008, specifies to 

contact Boeing for repair: Before further 

flight, repair using a method approved in 

accordance with the procedures specified in 

paragraph (i) of this AD. 

Alternative Methods of Compliance 

(AMOCs) 

(i)(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: Ivan 

Li, Aerospace Engineer, Airframe Branch, 

ANM–120S, FAA, Seattle Aircraft 

Certification Office, 1601 Lind Avenue, SW., 

Renton, Washington 98057–3356; telephone 

(425) 917–6437; fax (425) 917–6590. 

(2) To request a different method of 

compliance or a different compliance time 

for this AD, follow the procedures in 14 CFR 

39.19. Before using any approved AMOC on 

any airplane to which the AMOC applies, 

notify your principal maintenance inspector 

(PMI) or principal avionics inspector (PAI), 

as appropriate, or lacking a principal 

inspector, your local Flight Standards District 

Office. The AMOC approval letter must 

specifically reference this AD. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair 

required by this AD, if it is approved by an 

Authorized Representative for the Boeing 

Commercial Airplanes Delegation Option 

Authorization Organization who has been 

authorized by the Manager, Seattle ACO, to 

make those findings. For a repair method to 

be approved, the repair must meet the 

certification basis of the airplane, and the 

approval must specifically refer to this AD.
