SUMMARY;The FAA is adopting a new

airworthines:; directive (AD] for aU

Boeing Model 757 airplane~. This AD

requires revising the Airw,orthiness

Limitation~ (AWLs) section of the

InstructiDIlS for Continued

Airworthiness by incorporating new

Iimitation~ for fuel tank systems to

satisfy Special Federal Aviation

Regulation No, 88 requirement:;. This

AD also requires the initial in:;plJction of

certilin repetiti ve AWL inspections to

phase-in those in:;pectiOlls, and repair if

necA~sary. Thi:; AD re~ulls from a design

review of the fucl tank systems, We are

issuing this AD to prevent the potential

for ignition sources Inside fuel tanks

caused by latent failures, alterations,

repairs, 01'maintenance actions, which,

in combination with flammable fuel

vapors, could result iu a fuel tank

explosion and COll5equent loss ofths

ilirplane.

DATES:This AD becomes effective June

SUPPLEMENTARYINFORMATION:

Di~cu~~ion

The FAA issued a supplemental

notice of pl'Oposed rulemaking [NPRM)

to amend 14 CFR part 39 to include an

AD that '.vould apply to all Boeing

Model 757 airplanes, Thn\ supplemental

NPRM 1NaspublishAd in the f"ederal

Register on August 1. 2007 (72. FR

41963J, Thill supplemental NPRM

proposed to require revising the

Airworthiness Limitations [AWLs]

section of the Instructions for ContInued

Airworthiness (ICA) by incorporating

new limitations for fuel tank systems to

sati~fy Special Federal Aviation

Regulation No. 88 requirements. That

supplemental NPRIvl also proposed to

require the initial inspection of certain

repetitive inspections sper.ified in the

AWLs to phase-in thos!:! inspeclion~,

and repair ifnece~sary. That

supplemental NPRM also proposed to

revise the original NPRM by aligning the

compliance time for revising the AWLs

section with the compliance date of the

special maintenance program

requirement:;, updating the listing of

applicable airplane maintenance

manuals ill Appendix 1, and clarifying

certain actions,

Actions Since Supplemental NPRM

Was Issued

Since we issued the supplemental

NPRIvl, Boeing has issued Temporary

Revision [TRJ 09-008. dated March

2008. Boeing TR 09-008 is published as

Section 9 of the Boeing 757

MaintenallCe Planning Document (MPD)

Document, D622N001-9, Revision

March 2008 [hereflfter referred to as

"Revi,ion March 2008 of the M!'i)"),

The supplemental NPRM referred to

Revision March 2006 of the MPD as the

appropriate source of :;orvice

information [or ilccompLishing the

proposed actions. Revision Man:h 2008

of the MPD, among other aclir)lls.

includes the following changes:

G Removes the repetitive task intervnl

of 36,000 flight cycles from AWLs No.

28-AWL-0J, No. 28-AWL-03, and No.

28-AWL-14.

o Revi~es the ta~k description for

AWL No. 2B-AWL-Ql to harmonize it

with AWL No. 26-AWL-02 by removing

references to certain station numburs.

o Revises AWL No, 28-A WL-03 to

renect the new maximum loop

resistance values associilted with the

lightning pl'Otllction of the

unpressurlzed fuel quantity indicatiog

system [FQIS) wile bundle installations.

Accordingly, we hilve revised

paragraphs (fl, [g). and (h) of this AD to

refer to Revision March 2008 of the

MPD. We also have added a new

paragraph (j) to this /\0 specifying that

actions done before the effective date of

this AD in accordance 1Nith RlJvisions

March 2006 thl'Ough November 2U07 of

the MPD ilre acceptable for cOI!lpiiance

with the corresponding re4uirements of

paragraphs [g) and (hl of this AD.

We also have removed reference to

:J6,000 lolal flight cycles from Table 1 of

this AD and revised the initial threshold

for accomplishing AWLs No. 28-AWL01. No. 28-AWL-03, and No. 28-AWL14 to within 120 months since the date

of issuance of the original slandard

airworthiness certificate or the dale of

issuance of the origina.l flxport

[:ertificate of airwort!lina,s,
Federal Register I Vol. 73, No. 90 !Thursday, May B, 2008/RulGS and Regulations 25975

Operators should note that we have

revised paragraph (g) of this AD to

mquire illcorpl)rating Daly 1\WLs No,

28-AWL-Ol through No. 28-AWL-24

inclusive. AWL No. 28-AWL-25 was

added in Revision October 2006 of the

MPD, and AWL No. 28-AWL-26 was

added in Revision January 2007 of the

MPD, However, as an optiona.! ac.:tion,

operators may incorporate those AWLs

as specified in paragrnph (g) of this AD,

We have issued a separate NPRM

[Docket No, FAA-2007-28598) that, in

part, propo~es to incorporate AWLs No.

28-AWL-20 and No, 2fl-AWL-26 into

the 1\WLs section of the leA. That

NPKM was publish8d in the Federal

Register ouJuly 9. 2007 (72 PR 37UZ).

We have illso issued AD 2008-05-03,

amendment 39-15415 (73 FR 130fll,

Man:h 12, 2008) tbil\, in part, requires

revising theAWL~ ~ectioll of the lCA to

incorporate AWLs No. 2(1-1\WL-23. No.

28-AWL-24. and No. 28-AWL-25.

Therefore. we have added a new

paragraph {kJto this AD specifying that

incorporating AWLs No, 28-A WL-23,

No, 28-AWL--24, and No, 28-A WL-25

in accordance with paragraph (g) of this

AD terminates the a.ction required by

paragraph (h)(Z) of AD 200S-Q6-03.

Other Changes Marle to This AD

We have reviseu paragraph (h) of this

AD tD clarify iliat the actions identified

in T<Jble 1 of this AD must be done at

the compLiance time spec:ifisd in that

table, Also, for standardization

purposes. we have revised this r\D in

the following ways:

Q We have addeda new paragraph (i)

to this AD to specify that no alternative

inspections, inspection intervals, or

critical design configuration control

limitations (CDCCLs) lllay be used

unless they are part of ~ later approvl-Jd

revision of Revisioll March 2008 of the

MPD, or unless they are appruved as an

alternative method of compliance

(AMOCj, Inclusion of this paragraph ill

the AD is inteIld~d to ensure that the

AD-mandated auwol'thiness limitations

changes are treated the same a~ the

airworthiness limitations issued with

the original type certificate.

• We have revi~ed Note 1 of thIs AD

to clarify that an operator must request

approval fo!' an AMOC if the operator

cannot accomplish the proposed

inspections because an airplane has

been previously modified, altered. or

r8paired in the areas addres~ed by the

proposed inspections .

• We have revised paragraph (h) of

thi~ AD to specify that accomplishing

the applicllble AWLs in Table 1 of this

AD as part of an FAA-approved

maintenance program before the

applicable compliance time constitutes

compliance with the applicable

requiremeIlts of that paragraph,

Q We have deleted Appendix 1 from

this AD, since Revision March 2008 of

the MPD aheady contains most of the

updated information that is listed in

Appendix 1 of the NPRM.

Cumrnell!s

We provided the public the

opportunity to participate in the

development ofthi~ AD, We have

considered the comments received.

Request To Extend lbc Task Intervals

for Certain AWI. Inspections

KLM Royal Dutr.h Airlines, on behalf

or several operators, req uests !lwt we

review a 45-pflge proposal to align

certain airworthiness limitation item

(ALl) intervals with the applicahle

maintenance significant item (MS!) and

enhanced zonal analysis procedure

(EZAP) intervals for Moclel 737, 747,

757,757, and 777 airplanes, The

recommendations in that proposal

ensure that the ALl intervals align with

the maintenance schl1dules of the

uperators, Among other changes, the

proposal recommends extending certain

AWL inspection intervals from 10 yearsl

35,000 flight cycles to 12 years for

Model 757 ail'planes.

We disagree \Nith KLM's request to

extend certain AWL inspection intervals

to 12 years. However, as stated

previously. we have deleted the 36,000-

total-night-cycle parameter from Table 1

of this AD to correspond with the task

intervals specified in Revision March

2008 of the MPD. In developing an

appwpriate compliance time for this

acuon. we considered the urgency

Ilssociated with the subject unsafe

condition and the practical aspect of

accomplishing the required actions

withil] a period of time that corresponds

10 the normal scheduled maintenance

for most affected operators. HO\Never,

according to the provisions of paragraph

(I) of this AD, we might approve

requests to adjust the compliance time

ifthe reqlwst includes data that prove

that the new compliance lime would

provide an acceptable level of ~afsty.

Request To Revise the Loop Resistance

Values for AWL No. 2B-AWL-03

Boeing stEltes that tbe loop resistance

values for AWL No. 28-AWL--03

specified in Revision Marcb 2006 of the

MFD are going to be revised, since those

values are relevant for production

airplanes. Boeing also states that the

revised values will be more

representative of the expected values for

in·service airplallss. BoeIng points out

th~t, ilccording to paragraph (h) of the

supplemental NPRM, the revised values

should be able to be used in accordance

with a later revision of the MPD if the

revision is approved by the Seattle

Aircraft Certification Office [ACO),

FAA

We agree that operators may use the

revis8d loop resistance value~ for AWL

No, 28_AWL_03 in accordance witb

Revision March 2008 of th8 MPD. As

stated previously, we have revised tbis

AD accordingly.

Request To Revise Note 1

!:loeing requests that we revi~e Note 1

of the supplemental NPRM to clarify the

need for an AMOC. Boeing states thilt

the cunent wOlding is diffic.:ult to

[ollow, and that the note is meant to

inform opsrators th"t an AMOC to the

required MPD AV,'Ls might be required

if an operator has previously modified.

altered, or repaired the areas addressed

by the lirnitatiom. Boeing requests that

we revise Note 1 as follows:

Q Add the \,vords "according to

paragraph (g)" at the end of the first

sentence.

o Replace the words "revision to"

with "deviation from" in the last

sentence.

Q Delete the 'Nords "[g) or" and "as

applicable" from the last seutence.

hs stated prsviously. we have

simplified the language in Note 1 of this

AD for standardization willl other

similar ADs. The language the

commenter requests that we change

does not appear in the revised note.

Therefore, no additional change to this

AD is necessary in this regard.

Condusion

We have carefully reviewed the

available datil, including the comments

received, and determined that air safety

and the public interest require adopting

the AD with the changes described

previously. We>have determined that

these changes will neither increase the

ecouomic burden un any operator nor

increase the scope of tile AD.

Costs of Compliance

There are about 990 a.irplanes of the

affected design in the worldwide fle>el.

The following table provides the

estimated costs, Ht an aVel'age labor rate
