Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–100, 

747–100B, 747–100B SUD, 747–200B, 

747–200C, 747–200F, 747–300, 747– 

400, 747–400D, 747–400F, 747SR, and 

747SP series airplanes. This proposed 

AD was prompted by several reports of 

chafing of the wire bundles inside the 

electrical conduit of the forward and aft 

boost pumps of the numbers 1 and 4 

main fuel tanks due to high vibration. 

These wire bundles can chafe through 

the wire sleeving into the insulation, 

exposing the wire conductors. This 

proposed AD would require replacing 

the wire bundles inside the electrical 

conduit of the forward and aft boost 

pumps of the numbers 1 and 4 main fuel 

tanks with new, improved wire bundles 

inserted into conduit liners. We are 

proposing this AD to prevent chafing of 

the wire bundles and subsequent arcing 

between the wiring and the electrical 

conduit creating an ignition source in 

the fuel tanks, which could result in a 

fire and consequent fuel tank explosion. 

DATES: We must receive comments on 

this proposed AD by June 15, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2015–0935; Directorate Identifier 2014– 

NM–243–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received several reports of 

chafing of the wire bundles inside the 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 80, No. 84 / Friday, May 1, 2015 / Proposed Rules 24851 

electrical conduit of the forward and aft 

boost pumps of the numbers 1 and 4 

main fuel tanks due to high vibration. 

These wire bundles can chafe through 

the wire sleeving into the insulation, 

exposing the wire conductors. These 

conditions, if not prevented, could 

result in arcing between the wiring and 

the electrical conduit creating an 

ignition source in the fuel tanks, which 

could result in a fire and consequent 

fuel tank explosion. 

Related AD 

AD 2011–15–03, Amendment 39– 

16750 (76 FR 41659, July 15, 2011), 

superseded AD 97–26–07, Amendment 

39–10250 (62 FR 65352, December 12, 

1997), and continues to require 

repetitive inspections to detect damage 

of the sleeving and wire bundles of the 

boost pumps of the numbers 1 and 4 

main fuel tanks, and of the auxiliary 

tank jettison pumps (if installed); 

replacement of any damaged sleeving 

with new sleeving; and repair or 

replacement of any damaged wires with 

new wires. For airplanes on which any 

burned wires are found, AD 2011–15–03 

also continues to require an inspection 

to detect damage of the conduit, and 

replacement of any damaged conduit 

with a serviceable conduit. AD 2011– 

15–03 reduced the initial compliance 

time and repetitive inspection interval 

in AD 97–26–07. AD 2011–15–03 was 

prompted by fleet information 

indicating that the repetitive inspection 

interval in AD 97–26–07 was too long 

because excessive chafing of the 

sleeving continued to occur much 

earlier than expected between 

scheduled inspections. Accomplishing 

the replacement specified in this 

proposed AD would terminate the 

repetitive inspections required by 

paragraph (n) of AD 2011–15–03. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin 747–28A2306, dated October 2, 

2014. The service information describes 

procedures for replacing the wire 

bundles of the electrical conduit inside 

the electrical conduit of the forward and 

aft boost pumps of the numbers 1 and 

4 main fuel tanks. This service 

information is reasonably available at 

http://www.regulations.gov by searching 

for and locating Docket No. FAA–2015– 

0935. Or see ADDRESSES for other ways 

to access this service information. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information identified 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 176 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Replacement ...................... Up to 53 work-hours × $85 per hour = $4,505 ............ $4,600 Up to $9,105 ......... Up to $1,602,480. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

The Boeing Company: Docket No. FAA– 

2015–0935; Directorate Identifier 2014– 

NM–243–AD. 

(a) Comments Due Date

(d) Subject 

Air Transport Association (ATA) of 

America Code 28, Fuel. 

(e) Unsafe Condition 

This AD was prompted by several reports 

of chafing of the wire bundles inside the 

electrical conduit of the forward and aft boost 

pumps of the numbers 1 and 4 main fuel 

tanks due to high vibration. These wire 

bundles can chafe through the wire sleeving 

into the insulation, exposing the wire 

conductors. We are issuing this AD to 

prevent chafing of the wire bundles and 

subsequent arcing between the wiring and 

the electrical conduit creating an ignition 

source in the fuel tanks, which could result 

in a fire and consequent fuel tank explosion. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Replacement 

Within 60 months after the effective date

the electrical conduit of the forward and aft 

boost pumps of the numbers 1 and 4 main 

fuel tanks with new, improved wire bundles 

inserted into conduit liners, in accordance 

with the Accomplishment Instructions of 

Boeing Alert Service Bulletin 747–28A2306, 

dated October 2, 2014. Accomplishing the 

replacement required by this paragraph 

terminates the repetitive inspections required 

by paragraph (n) of AD 2011–15–03, 

Amendment 39–16750 (76 FR 41659, July 15, 

2011). 

(h) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle Aircraft 

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or local Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the ACO, send it to the 

attention of the person identified in 

paragraph (i)(1) of this AD. Information may 

be emailed to: 9-ANM-Seattle-ACO-AMOCRequests@faa.gov. 

(2) Before using any approved AMOC, 

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

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directives (ADs) 2001–18– 

06 and 2008–22–16, which apply to 

certain General Electric Company (GE) 

CT58 turboshaft engines. ADs 2001–18– 

06 and 2008–22–16 require 

recalculating the lives of life-limited 

rotating parts using a Repetitive HeavyLift (RHL) multiplying factor and 

removal from service of parts that 

exceed the recalculated cyclic or hourly 

life limit. This proposed AD would 

consolidate ADs 2001–18–06 and 2008– 

22–16, and further reduce the life 

capability of certain parts. We are 

proposing this AD to prevent failure of 

life-limited rotating parts, uncontained 

part release, damage to the engine, and 

damage to the aircraft. 

DATES: We must receive comments on 

this proposed AD by June 30, 2015.
