AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2008–08– 

25 that applied to certain The Boeing 

Company Model 747–400 and 747–400F 

series airplanes. AD 2008–08–25 

required installing drains and drain 

tubes to eliminate water accumulation 

in the drip shield above the M826 

cardfile in the main equipment center. 

This new AD requires installing 

modified drain tubes, relocating wire 

bundle routing, installing a new drip 

shield and drip shield deflectors, and 

replacing insulation blankets. For 

certain airplanes, this new AD also 

concurrently requires sealing the drain 

slot, installing spuds, and installing 

drain tubes. This AD was prompted by 

reports of continued water damage to 

diode fire card 285U0072–1 in the M826 

automatic fire overheat logic test system 

cardfile following a false FWD CARGO 

FIRE message, with no change in 

frequency, which resulted in an air turn 

back. We are issuing this AD to prevent 

water from exiting over the edge of the 

existing drip shield and contaminating 

electrical components in the M826 

cardfile, which could result in an 

electrical short and potential loss of 

several functions essential for safe 

flight. 

DATES: This AD is effective May 2, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of May 2, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2008–08–25, 

Amendment 39–15479 (73 FR 21240, 

April 21, 2008). AD 2008–08–25 applied 

to certain The Boeing Company Model 

747–400 and 747–400F series airplanes. 

The NPRM published in the Federal 

Register on September 6, 2012 (77 FR 

54854). The NPRM was prompted by 

reports of continued water damage to 

diode fire card 285U0072–1 in the M826 

automatic fire overheat logic test system 

cardfile following a false FWD CARGO 

FIRE message, with no change in 

frequency, which resulted in an air turn 

back. The NPRM proposed to require 

installing drain tubes, relocating wire 

bundle routing, installing a new drip 

shield and drip shield deflectors, and 

replacing insulation blankets. For 

certain airplanes, the NPRM also 

proposed to concurrently require sealing 

the drain slot, installing spuds, and 

installing drain tubes. We are issuing 

this AD to prevent water from exiting 

over the edge of the existing drip shield 

and contaminating electrical 

components in the M826 cardfile, which 

could result in an electrical short and 

potential loss of several functions 

essential for safe flight. 

Relevant Service Information 

Since we issued the NPRM (77 FR 

54854, September 6, 2012), we have 

reviewed Boeing Alert Service Bulletin 

747–25A3580, Revision 2, dated May 

13, 2013. We referred to Boeing Alert 

Service Bulletin 747–25A3580, Revision 

1, dated July 14, 2011, as an appropriate 

source of service information for 

accomplishing certain actions specified 

in the NPRM. 

Boeing Alert Service Bulletin 747– 

25A3580, Revision 2, dated May 13, 

2013, among other changes, revises line 

number 1087 to 1332 for group 1 

airplanes to account for airplanes that 

had the drain tubes installed in 

production, adds figures to account for 

actions required by certain groups, adds 

brackets and rivets, and changes certain 

part numbers of certain brackets. 

Boeing Alert Service Bulletin 747– 

25A3581, Revision 2, dated September 

11, 2012, among other things, clarifies 

wire routing, allows for trimming of 

parts, and adds parts to the top kit. 

We have added a new paragraph (i) to 

this final rule to allow for credit for 


tkelley on DSK3SPTVN1PROD with RULES
17404 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Rules and Regulations 

actions required by paragraph (g) of this 

AD, if those actions were performed 

before the effective date of this AD using 

Boeing Alert Service Bulletin 747– 

25A3580, Revision 1, dated July 14, 

2011, which is not incorporated by 

reference in this AD. We have 

redesignated subsequent paragraphs 

accordingly. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 54854, 

September 6, 2012) and the FAA’s 

response to each comment. 

Request To Use Latest Service 

Information 

United Parcel Service (UPS) and 

Boeing requested that we revise the 

NPRM (77 FR 54854, September 6, 

2012) to replace Boeing Alert Service 

Bulletin 747–25A3581, Revision 1, 

dated June 30, 2011, with Boeing Alert 

Service Bulletin 747–25A3581, Revision 

2, dated September 11, 2012. UPS 

explained that Boeing Alert Service 

Bulletin 747–25A3581, Revision 2, 

dated September 11, 2012, revises the 

effectivity, and includes changes, 

corrections, and clarifications to the 

work instructions. UPS reasoned that in 

order to avoid additional efforts of 

applying for, approving, and 

documenting alternative methods of 

compliance for using Boeing Alert 

Service Bulletin 747–25A3581, Revision 

2, dated September 11, 2012, we should 

instead revise the NPRM to incorporate 

Boeing Alert Service Bulletin 747– 

25A3581, Revision 2, dated September 

11, 2012, which, according to Boeing, 

would change paragraphs (c)(2), (g), and 

(h) of the NPRM. 

We partially agree. We disagree with 

the request to change paragraphs (c)(2) 

and (h) of this AD. Boeing Alert Service 

Bulletin 747–25A3581, Revision 2, 

dated September 11, 2012, adds one 

new airplane to the effectivity and 

would require resubmittal of the NPRM 

(77 FR 54854, September 6, 2012) for 

public comment on this change, which 

would delay the publication of this final 

rule. To delay this action would be 

inappropriate, since we have 

determined that an unsafe condition 

exists and that the required actions must 

be conducted to ensure continued 

safety. We might consider further 

rulemaking at a later time to address the 

additional airplane. However, we do 

agree to revise paragraph (g) of this AD 

by also referring to Boeing Alert Service 

Bulletin 747–25A3581, Revision 2, 

dated September 11, 2012, as an 

appropriate method of compliance for 

the actions required by paragraph (g) of 

this AD. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this 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 (77 FR 

54854, September 6, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 54854, 

September 6, 2012). 

Costs of Compliance 

We estimate that this AD affects 38 

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 

Installation, relocation, and replacement.Up to 23 work-hours × $85 per 

hour = $1,955.

Up to $8,887 ............... Up to $10,842 ............. Up to $411,996. 

Concurrent installation .................... 8 work-hours × $85 per hour = 

680.

$1,801 ......................... $2,481 ......................... $94,278. 

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 

We have 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 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.
