Airworthiness Directives; The Boeing 

Company Model MD–11 and MD–11F 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

a one-time inspection to detect damage 

of the wire assemblies of the tail tank 

fuel system, a wiring change, and 

corrective actions if necessary. This AD 

also requires, for certain airplanes, a 

general visual inspection for correct 

installation of the self-adhering hightemperature electrical insulation tape; 

installation of a wire assembly support 

bracket and routing wire assembly; 

changing wire supports; and installation 

of a wire protection bracket. This AD 

was prompted by fuel system reviews 

conducted by the manufacturer. We are 

issuing this AD to detect and correct a 

potential of ignition sources inside fuel 

tanks, which, in combination with 

flammable vapors, could result in a fuel 

tank fire or explosion, and consequent 

loss of the airplane. 

DATES: This AD is effective February 16, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of February 16, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 to include an 

airworthiness directive (AD) that would 

apply to the specified products. That 

SNPRM published in the Federal 

Register on November 17, 2010 (75 FR 

70150). The original NPRM (75 FR 

12464, March 16, 2010) proposed to 

require a one-time inspection to detect 

damage of the wire assemblies of the tail 

tank fuel system, a wiring change, and 

corrective actions if necessary. The 

SNPRM proposed to revise the original 

NPRM by adding, for certain airplanes, 

a general visual inspection for correct 

installation of the self-adhering hightemperature electrical insulation tape; 

installation of a wire assembly support 

bracket and routing wire assembly; 

changing wire supports; and installation 

of a wire protection bracket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

FedEx supports the SNPRM. 

Explanation of Change Made to the AD 

We have revised this AD to identify 

the legal name of the manufacturer as 

published in the most recent type 

certificate data sheet for the affected 

airplane models. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes and the change described 

previously. We have determined that 

these minor changes: 

• Are consistent with the intent that 

was proposed in the SNPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the SNPRM. 

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 110 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

mstockstill on DSKH9S0YB1PROD with RULES

1984 Federal Register / Vol. 76, No. 8 / Wednesday, January 12, 2011 / Rules and Regulations 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. operators 

Inspection of tail tank fuel system wire assembly.1 work-hour × $85 per hour = $85 ................. $0 $85 $9,350. 

Inspection of electrical insulation tape ........... 1 work-hour × $85 per hour = $85 ................. 0 85 $9,350. 

Change wire supports .................................... 3 work-hours × $85 per hour = $255 ............. 9 264 Up to $29,040. 

We estimate the following costs to do 

any necessary installations and repairs 

that would be required based on the 

results of the inspection. We have no 

way of determining the number of 

aircraft that might need these 

installations and repairs. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Installation/repair .................................................... Up to 23 work-hours × $85 per hour = $1,955 ...... $11,829 Up to $13,784. 

Adjust tape installation ........................................... 1 × $85 per hour = $85 .......................................... 0 $85. 

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.

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

This AD results from mandatory 

continuing airworthiness information 

(MCAI) issued by an airworthiness 

authority of another country to identify 

and correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as 

Subsequent to accidents involving Fuel 

Tank System explosions in flight * * * and 

on ground, * * * Special Federal Aviation 

Regulation 88 (SFAR88) * * * required a 

safety review of the aircraft Fuel Tank 

System * * *. 

* * * * * 

Fuel Airworthiness Limitations are items 

arising from a systems safety analysis that 

have been shown to have failure mode(s) 

associated with an ‘unsafe condition’ * * *. 

These are identified in Failure Conditions for 

which an unacceptable probability of ignition 

risk could exist if specific tasks and/or 

practices are not performed in accordance 

with the manufacturers’ requirements. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

February 16, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

August 4, 2010 (75 FR 46864), and 

proposed to supersede AD 2006–12–18, 

Amendment 39–14644 (71 FR 34801, 

June 16, 2006). That NPRM proposed to 

require revising the airplane flight 

manual (AFM); revising the 

Airworthiness Limitation (AWL) 

section; doing a resistance check, 

inspection, and jumper installation; and 

revising the AWL section. The MCAI 

states:
