Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 727 airplanes. 

This AD was prompted by reports of 

cracks on the elevator rear spar stiffener 

assembly. This AD requires repetitive 

detailed inspections for cracking of the 

elevator rear spar stiffener assembly, 

and corrective actions if necessary. We 

are issuing this AD to detect and correct 

cracking of the elevator rear spar 

stiffener assembly, which could 

adversely affect elevator structural 

stiffness, which could lead to elevator 

vibration and possible interference with 

the tab control rod. These conditions 

could result in flutter and consequent 

loss of control of the airplane. 

DATES: This AD is effective August 26, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of August 26, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. The 

NPRM published in the Federal 

Register on April 11, 2013 (78 FR 

21569). The NPRM proposed to require 


ehiers on DSK2VPTVN1PROD with RULES
Federal Register / Vol. 78, No. 140 / Monday, July 22, 2013 / Rules and Regulations 43771 

repetitive detailed inspections for 

cracking of the elevator rear spar 

stiffener assembly. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

Supportive Comments 

Boeing stated that it supports the 

NPRM (78 FR 21569, April 11, 2013). 

FedEx stated that the requirements 

proposed in the NPRM (78 FR 21569, 

April 11, 2013) would fit within the 

planned scheduled maintenance check 

and not impact fleet availability or spantime of the planned scheduled 

maintenance check. 

Conclusion 

We reviewed the relevant data, 

considered the comments 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 (78 FR 

21569, April 11, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 21569, 

April 11, 2013). 

Costs of Compliance 

We estimate that this AD affects 98 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Inspection .......... 5 work-hours × $85 per hour = $425 per inspection cycle.None ................. $425 per inspection 

cycle.

$41,650 per inspection 

cycle 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need this replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement .... 7 work-hours × $85 per hour = $595 .............................................................................. Unknown ........... $595 

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), 

(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

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 airworthiness 

directive (AD): 

2013–14–03 The Boeing Company: 

Amendment 39–17508 ; Docket No. FAA– 

2013–0299; Directorate Identifier 2012– 

NM–072–AD. 

(a) Effective Date 

This AD is effective August 26, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all The Boeing 

Company Model 727, 727C, 727–100, 727– 

100C, 727–200, and 727–200F series 

airplanes, certificated in any category. 

(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 55, Stabilizers. 

(e) Unsafe Condition 

This AD was prompted by reports of cracks 

on the elevator rear spar stiffener assembly. 

We are issuing this AD to detect and correct 

cracking of the elevator rear spar stiffener 

assembly, which could adversely affect 

elevator structural stiffness, which could lead 

to elevator vibration and possible 

interference with the tab control rod. These 

conditions could result in elevator flutter and 

consequent loss of control of the airplane.

SUPPLEMENTARY INFORMATION: 

History 

On October 26, 2012, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to modify the Las Vegas, NV, Class B 

airspace area (77 FR 65332). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal. 

By letter dated December 7, 2012, the 

Aircraft Owners and Pilots Association 

(AOPA) requested that the FAA extend 

the comment period for at least 30 days. 

AOPA stated that the original comment 

period encompassed two Federal 

holiday periods and that no comments 

had been posted to the docket as of the 

date of their letter. The FAA determined 

that reopening of the comment period 

was consistent with the public interest. 

On January 14, 2013, the FAA published 

in the Federal Register a notice 

reopening the comment period until 

February 13, 2013 (78 FR 2646). 

The Aircraft Owners and Pilots 

Association (AOPA) and six individuals 

responded to the NPRM comment 

periods. The FAA considered all 


ehiers on DSK2VPTVN1PROD with RULES
