Federal Register / Vol. 78, No. 41 / Friday, March 1, 2013 / Proposed Rules 13843 

the pressure P within the tank varies in 

accordance with the formula: 

P = KrgL 

Where 

P = fuel pressure at each point within the 

tank. 

r = typical fuel density. 

g = acceleration due to gravity. 

L = a reference distance between the point of 

pressure and the tank farthest boundary 

in the direction of loading. 

K = 4.5 for the forward loading condition for 

those parts of fuel tanks outside the 

fuselage pressure boundary. 

K = 9 for the forward loading condition for 

those parts of fuel tanks within the 

fuselage pressure boundary, or that form 

part of the fuselage pressure boundary. 

K = 1.5 for the aft loading condition. 

K = 3.0 for the inboard and outboard loading 

conditions for those parts of fuel tanks 

within the fuselage pressure boundary, 

or that form part of the fuselage pressure 

boundary. 

K = 1.5 for the inboard and outboard loading 

conditions for those parts of fuel tanks 

outside the fuselage pressure boundary. 

K = 6 for the downward loading condition. 

K = 3 for the upward loading condition. 

(2) For those parts of wing fuel tanks 

near the fuselage or near the engines, 

the greater of the fuel pressures 

resulting from paragraphs (d)(2)(i) and 

(d)(2)(ii) of this section must be used: 

(i) The fuel pressures resulting from 

paragraph (d)(1) of this section, and 

(ii) The lesser of the two following 

conditions: 

(A) Fuel pressures resulting from the 

accelerations as specified in 

§ 25.561(b)(3) considering the fuel tank 

full of fuel at maximum fuel density. 

Fuel pressures based on the 9.0g 

forward acceleration may be calculated 

using the fuel static head equal to the 

streamwise local chord of the tank. For 

inboard and outboard conditions, an 

acceleration of 1.5g may be used in lieu 

of 3.0g as specified in § 25.561(b)(3), 

and 

(B) Fuel pressures resulting from the 

accelerations as specified in 

§ 25.561(b)(3) considering a fuel volume 

beyond 85% of the maximum 

permissible volume in each tank using 

the static head associated with the 85% 

fuel level. A typical density of the 

appropriate fuel may be used. For 

inboard and outboard conditions, an 

acceleration of 1.5g may be used in lieu 

of 3.0g as specified in § 25.561(b)(3). 

(3) Fuel tank internal barriers and 

baffles may be considered as solid 

boundaries if shown to be effective in 

limiting fuel flow. 

(4) For each fuel tank and 

surrounding airframe structure, the 

effects of crushing and scraping actions 

with the ground should not cause the 

spillage of enough fuel, or generate 

temperatures that would constitute a 

fire hazard under the conditions 

specified in § 25.721(b). 

(5) Fuel tank installations must be 

such that the tanks will not rupture as 

a result of an engine pylon or engine 

mount or landing gear, tearing away as 

specified in § 25.721(a) and (c).

■ 8. Revise § 25.994 to read as follows: 

§ 25.994 Fuel system components. 

Fuel system components in an engine 

nacelle or in the fuselage must be 

protected from damage that could result 

in spillage of enough fuel to constitute 

a fire hazard as a result of a wheels-up 

landing on a paved runway under each 

of the conditions prescribed in 

§ 25.721(b).

Circular No. 11–2A, Notice of Proposed 

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

The FAA is proposing an amendment 

to Title 14 Code of Federal Regulations 

(14 CFR) Part 71 by modifying Class E 

airspace extending upward from 700 

feet above the surface at Bend 

Municipal Airport, Bend, OR. 

Additional airspace is needed to 

accommodate Area Navigation (RNAV) 

Global Positioning System (GPS) 

standard instrument approaches and 

departures at the Airport. This action is 

necessary for the safety and 

management of aircraft departing and 

arriving under IFR operations at Bend 

Municipal airport. The geographic 

coordinates of the airport would also be 

updated. Class E airspace designations 

are published in paragraph 6005 of FAA 

Order 7400.9W, dated August 8, 2012, 

and effective September 15, 2012, which 

is incorporated by reference in 14 CFR 

Part 71.1. The Class E Class E airspace 

designations are published in paragraph 

6005, of FAA Order 7400.9W, dated 

August 8, 2012, and effective September 

15, 2012, which is incorporated by 

reference in 14 CFR 71.1. The Class E 

airspace designation listed in this 

document will be published 

subsequently in this Order. 

The FAA has determined this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore, this proposed regulation; (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) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified this proposed rule, when 

promulgated, would not have a 

significant economic impact on a 

substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

Section 106, describes the authority for 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the agency’s 

authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

modify controlled airspace at Bend 

Municipal Airport, OR. 

This proposal will be subject to an 

environmental analysis in accordance 

with FAA Order 1050.1E, 

‘‘Environmental Impacts: Policies and 

Procedures’’ prior to any FAA final 

regulatory action.
