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 certain 

the Boeing Company Model 777–200, 

–200LR, and –300ER series airplanes. 

This AD was prompted by a report from 

the manufacturer indicating that the 

lowered ceiling support structure of 

Section 41, in airplanes incorporating 

the overhead space utilization (OSU) 

option, was found to be under-strength 

when subjected to a 9.0 g forward load. 

This AD requires installing new 

structural members, tie rod(s), and 

attach fittings on the left and right sides 

of the lowered ceiling support structure. 

We are issuing this AD to prevent the 

forward lowered ceiling panels and 

support structure from becoming 

dislodged during a 9.0 g forward load 

and consequent injury to personnel or 

interference with an emergency 

evacuation. 

DATES: This AD is effective July 30, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 30, 2012.

SUPPLEMENTARY INFORMATION: 


erowe on DSK2VPTVN1PROD with RULES
37794 Federal Register / Vol. 77, No. 122 / Monday, June 25, 2012 / Rules and Regulations 

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. That 

NPRM published in the Federal 

Register on November 30, 2011 (76 FR 

74012). That NPRM proposed to require 

installing new structural members in 

and new tie rod(s) and attach fittings on 

the left and right sides of the lowered 

ceiling support structure. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (76 FR 74012, 

November 30, 2011) and the FAA’s 

response to each comment. 

Request to Include Latest Revision of 

Service Information 

United Airlines, Air France, and 

Boeing requested that we revise the 

proposed rule (76 FR 74012, November 

30, 2011) to reflect the latest revision of 

the service information in this AD. 

We agree. Boeing has issued Boeing 

Special Attention Service Bulletin 777– 

25–0482, Revision 1, dated February 21, 

2012. This service bulletin was revised 

due to minor changes to correct 

hardware and location for its 

installation. We have changed this final 

rule to reference Boeing Special 

Attention Service Bulletin 777–25– 

0482, Revision 1, dated February 21, 

2012, and changed total task hours in 

the Costs of Compliance section of this 

AD from 19 hours to 23 hours to 

account for the revised labor hours. 

Paragraph (h) of this final rule has also 

been added to give credit for actions 

performed before the effective date of 

this AD using Boeing Special Attention 

Service Bulletin 777–25–0482, dated 

February 24, 2011. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

74012, November 30, 2011) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 74012, 

November 30, 2011). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 4 

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 

Install ceiling support structure members, fittings, and tie rods.23 work-hours × $85 per hour = $1,955 ........ $13,329 $15,284 $61,136 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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.

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.

Airworthiness Directives; Dassault

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain Dassault Aviation Model 

FALCON 7X airplanes. That AD 

currently requires revising the 

Abnormal Procedures and Limitations 

sections of the Dassault F7X Airplane 

Flight Manual. This new AD requires a 

test of the power distribution control 

units (PDCU) cards and generator 

control units (GCU) cards to detect 

faulty components, and if any faulty 

components are found, replacing any 

affected PDCU or GCU card. This AD 

was prompted by a determination that 

additional actions are necessary to 

address the identified unsafe condition. 

We are issuing this AD to detect and 

correct a leakage failure mode of 

transient voltage suppression (TVS) 

diodes used on PDCU cards or GCU 

cards in the primary power distribution 

boxes (PPDB), which, in combination 

with other system failures, could lead to 

loss of controllability of the airplane. 

DATES: This AD becomes effective July 

30, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of July 30, 2012.

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. That 

NPRM was published in the Federal 

Register on March 15, 2012 (77 FR 

15293), and proposed to supersede AD 

AD 2010–18–03, Amendment 39–16416 

(75 FR 51931, August 24, 2010). 

On August 11, 2010, we issued AD 

2010–18–03, Amendment 39–16416 (75 

FR 51931, August 24, 2010). That AD 

required actions intended to address an 

unsafe condition on certain Dassault 

Aviation Model FALCON 7X airplanes. 

The preamble of AD 2010–18–03 

explains that we consider the 

requirements of that AD ‘‘interim 

action’’ and are considering further 

rulemaking to mandate inspection 

(testing) of the PDCU and GCU cards 

and replacement of faulty cards, as 

required by European Aviation Safety
