Airworthiness Directives; the Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2010–03– 

05 for all the Boeing Company Model 

747–200C and –200F series airplanes. 

AD 2010–03–05 required, for the upper 

chords of the upper deck floor beam of 

section 41, an inspection for cracking of 

certain fastener holes, and corrective 

action if necessary; and repetitive 

replacements of the upper chords, straps 

(or angles), and radius fillers of certain 

upper deck floor beams and, for any 

replacement that is done, inspections 

for cracking, and corrective actions if 

necessary. This new AD adds repetitive 

inspections of the upper chords of the 

upper deck floor beam of Section 42, 

repetitive replacements of the upper 

chords, post-replacement inspections, 

and corrective actions if necessary. This 

new AD also adds post-replacement 

inspections for section 41 and reduces 

certain compliance times. This AD was 

prompted by a determination that the 

upper deck floor beams are subject to 

widespread fatigue damage (WFD), the 

existing inspection program is not 

sufficient to maintain an acceptable 

level of safety, and the upper chords of 

the upper deck floor beam of section 42 

are subject to the unsafe condition. We 

are issuing this AD to detect and correct 

cracking of the upper chords and straps 

(or angles) of the floor beams, which 

could lead to failure of the floor beams 

and consequent loss of controllability, 

rapid decompression, and loss of 

structural integrity of the airplane. 

DATES: This AD is effective November 7, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 7, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2010–03–05, 

Amendment 39–16188 (75 FR 5692, 

February 4, 2010). AD 2010–03–05 

applied to all The Boeing Company 

Model 747–200C and –200F series 

airplanes. The NPRM published in the 

Federal Register on May 28, 2014 (79 

FR 30486). The NPRM was prompted by 

a determination that the upper deck 

floor beams are subject to WFD, the 

existing inspection program is not 

sufficient to maintain an acceptable 

level of safety, and the upper chords of 

the upper deck floor beams in section 42 

are subject to the identified unsafe 

condition. The NPRM proposed to add 

post-replacement inspections for section 

41 and reduce certain compliance times. 

The NPRM also proposed to add 

repetitive inspections of the upper 

chords of the upper deck floor beams in 

section 42, repetitive replacements of 

the upper chords, post-replacement 

inspections, and corrective action if 

necessary. We are issuing this AD to 

detect and correct cracking of the upper 

chords and straps (or angles) of the floor 

beams, which could lead to failure of 

the floor beams and consequent loss of 

controllability, rapid decompression, 

and loss of structural integrity of the 

airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Boeing stated that it concurs with the 

contents of the NPRM (79 FR 30486, 

May 28, 2014). 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

30486, May 28, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 30486, 

May 28, 2014). 

Costs of Compliance 

We estimate that this AD affects 25 

airplanes of U.S. registry.

We have received no definitive data

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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

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 

removing Airworthiness Directive (AD) 

2010–03–05, Amendment 39–16188 (75 

FR 5692, February 4, 2010), and adding 

the following new AD: 

2014–20–07 The Boeing Company: 

Amendment 39–17980; Docket No. 

FAA–2014–0283; Directorate Identifier 

2012–NM–183–AD. 

(a) Effective Date 

This AD is effective November 7, 2014. 

(b) Affected ADs 

This AD replaces AD 2010–03–05, 

Amendment 39–16188 (75 FR 5692, February 

4, 2010). 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 747–200C and –200F series 

airplanes, certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Unsafe Condition 

This AD was prompted by a determination 

that the upper deck floor beams are subject 

to widespread fatigue damage (WFD), the 

existing inspection program is not sufficient 

to maintain an acceptable level of safety, and 

upper chords of the upper deck floor beam 

of section 42 are subject to the unsafe 

condition. We are issuing this AD to detect 

and correct cracking of the upper chords and 

straps (or angles) of the floor beams, which 

could lead to failure of the floor beams and 

consequent loss of controllability, rapid 

decompression, and loss of structural 

integrity of the airplane.

compliance times specified, unless already 

done.

(o) Alternative Methods of Compliance 

(AMOCs) 

(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. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or local Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the ACO, send it to the 

attention of the persons identified in 

paragraph (p)(1) of this AD. Information may 

be emailed to: 9-ANM-Seattle-ACO-AMOCRequests@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/

certificate holding district office. 

(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 the 

Boeing Commercial Airplanes Organization 

Designation Authorization (ODA) that 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.
