AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Compass mismatch (up to loss of heading 

information) were reported by operators, due 

to ferro-magnetic masses (like the telescopic 

Tow-Bar) stowed in the baggage 

compartment. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

March 31, 2011. 

On March 31, 2011, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

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 November 3, 2010 (75 FR 

67639). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Compass mismatch (up to loss of heading 

information) were reported by operators, due 

to ferro-magnetic masses (like the telescopic 

Tow-Bar) stowed in the baggage 

compartment. A limitation was added to the 

approved Airplane Flight Manual, stating 

that the towing bar P/N 01–1227–0000 or 

similar ferromagnetic masses are prohibited 

to be carried in the baggage compartment. 

We require the incorporation of Piaggio 

Aero Industries S.p.A. and Piaggio Aero 

Industries (Piaggio) Temporary Change 

No. 7, into the Pilot’s Operating 

Handbook and EASA Approved 

Airplane Flight Manual Rep. 6591, 

issued: February 24, 2009, and 

Temporary Change No. 11 into the 

EASA Approved Airplane Flight 

Manual Rep. 180–MAN–0010–01100, 

issued: February 24, 2009, and 

installation of a placard. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Comment Issue: Study Relocation of 

Magnetic Flux Valves 

James Wright stated that investigation 

into the feasibility of relocating the 

magnetic flux valves to an area less 

susceptible to magnetic interference 

may be a better course of action. We 

infer that the commenter requests that 

we withdraw the AD action and relocate 

the magnetic flux valves to an area less 

susceptible to magnetic interference. 

We do not agree with the commenter. 

The current airplane flight manual 

limitation stipulates: 

The towing bar TRONAIR p/n 01–1227– 

0000 or other ferromagnetic masses with 

comparable mass and length are prohibited to 

be carried in the baggage compartment. 

Additionally, Piaggio evaluated the 

possibility of relocating the flux valve 

and concluded it should remain in its 

current location. Piaggio confirmed that 

a new tow bar made of aluminum is 

available and can be used on Model 

PIAGGIO P–180 airplanes. 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 76, No. 37 / Thursday, February 24, 2011 / Rules and Regulations 10225 

We are not changing the final rule AD 

action based on this comment. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

100 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $50 per 

product. 

Based on these figures, we estimate 

the cost of this AD to the U.S. operators 

to be $13,500 or $135 per product. 

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 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 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); and 

(3) 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 

9 a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Airworthiness Directives; The Boeing 

Company Model 757 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. That AD 

currently requires sealing the fasteners 

on the front and rear spars inside the 

left and right main fuel tanks and on the 

rear spar and lower panel of the center 

fuel tank. That AD also requires 

inspections of the wire bundle support 

installations to verify if certain clamps 

are installed and if Teflon sleeving 

covers the wire bundles inside the left 

and right equipment cooling system 

bays, on the left and right rear spars, 

and on the left and right front spars; and 

corrective actions if necessary. This new 

AD also requires sealing the additional 

fasteners on the rear spar inside the left 

and right main fuel tanks. This AD was 

prompted by a fuel system review 

conducted by the manufacturer. We 

have received reports from the 

manufacturer that additional fasteners 

in the main fuel tanks must be sealed for 

lightning strike protection. We are 

issuing this AD to detect and correct 

improper wire bundle support 

installation and sleeving and to prevent 

improperly sealed fasteners in the main 

and center fuel tanks from becoming an 

ignition source, in the event of a fault 

current or lightning strike, which could 

result in a fuel tank explosion and 

consequent loss of the airplane. 

DATES: This AD is effective March 31, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of March 31, 2011.
