ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model DC–9–10, 

DC–9–30, and DC–9–40 series airplanes. 

This AD was prompted by an evaluation 

by the design approval holder (DAH) 

indicating that the aft pressure bulkhead 

web area is subject to widespread 

fatigue damage (WFD). This AD requires 

modifying the aft pressure bulkhead. 

The modification includes inspecting 

for cracks around the rivet holes, and 

repair of any cracking. We are issuing 

this AD to prevent fatigue cracking of 

the aft pressure bulkhead, which could 

result in reduced structural integrity of 

the airplane. 

DATES: This AD is effective January 31, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 31, 2014.

SUPPLEMENTARY INFORMATION: 


tkelley on DSK3SPTVN1PROD with RULES
78704 Federal Register / Vol. 78, No. 249 / Friday, December 27, 2013 / Rules and Regulations 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM published in the Federal 

Register on September 11, 2013 (78 FR 

55662). The NPRM proposed to require 

modifying the aft pressure bulkhead. 

The modification includes inspecting 

for cracks around the rivet holes, and 

repair of any cracking. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 55662, September 11, 2013) or on the 

determination of the cost to the public. 

Change Made to this AD 

We have revised the service 

information citations throughout this 

final rule to correctly identify the 

manufacturer name specified on the 

service information. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

with the change described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

55662, September 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 55662, 

September 11, 2013). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Costs of Compliance 

We estimate that this AD affects 6 

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 

Modification (includes inspection) ................... 542 work-hours × $85 per hour = $46,070 .... $4,680 $50,750 $304,500 

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 

Air transportation, Aircraft, Aviation

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2010–24– 

07 for all Airbus Model A318 series 

airplanes, Model A319 series airplanes, 

Model A320 series airplanes, and Model 

A321 series airplanes. AD 2010–24–07 

required repetitive inspections of the 

80VU rack lower lateral fittings for 

damage, repetitive inspections of the 

80VU rack lower central support for 

cracking, and corrective action if 

necessary. AD 2010–24–07 also 

specified optional terminating action for 

the repetitive inspections. This new AD 

reduces the inspection compliance time, 

adds an inspection of the upper fittings 

and shelves of the 80VU rack, and adds 

airplanes to the applicability. This AD 

was prompted by reports of worn lower 

lateral fittings of the 80VU rack. We are 

issuing this AD to detect and correct 

damage or cracking of the 80VU fittings 

and supports, which could lead to 

possible disconnection of the cable 

harnesses to one or more computers, 

and if occurring during a critical phase 

of flight, could result in reduced control 

of the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on May 14, 2013 (78 FR 28152), 

and proposed to supersede AD 2010– 

24–07, Amendment 39–16526 (75 FR 

75878, December 7, 2010). The NPRM 

proposed to correct an unsafe condition 

for the specified products. The 

European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0134, 

dated July 18, 2012 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Damage to the lower lateral fittings of the 

80VU rack, typically elongated holes, 

migrated bushes, and/or missing bolts have 

been reported on in-service aeroplanes. The 

80VU rack contains computers for flight 

controls, communication and radionavigation. In addition, damage to the lower
