Airworthiness Directives; Boeing Model 737-400, -500, -600, -700, 
-700C, -800, and -900 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Boeing Model 737-400, -500, -600, -700, -700C, -800, and -900 series 
airplanes. This AD requires an inspection to determine the part and 
serial numbers of the windshield wiper motors for the pilot's and first 
officer's windshields, and doing applicable corrective actions. This AD 
results from two reports that the left and right windshield wipers 
stopped working in flight. We are issuing this AD to prevent

[[Page 71542]]

failure of the windshield wipers in wet weather, which could result in 
decreased visibility for the flightcrew.

DATES: This AD is effective December 30, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 30, 
2008.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
certain Boeing Model 737-400, -500, -600, -700, -700C, -800, and -900 
series airplanes. That NPRM was published in the Federal Register on 
February 8, 2008 (73 FR 7492). That NPRM proposed to require an 
inspection to determine the part and serial numbers of the windshield 
wiper motors for the pilot's and first officer's windshields, and the 
applicable corrective action.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request for Clarification of Certain Language

    Boeing asks that the language in Note 1 of the NPRM, which 
specifies ``determining the windshield wiper motor has been previously 
replaced,'' be changed for clarification to ``determining whether the 
power module replacement has been previously accomplished.'' Boeing 
states that the list included as part of Rosemount Aerospace Service 
Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006, provides 
information for determining whether the power module has been replaced 
with a properly soldered module.
    We agree that the language in Note 1 of the AD should be clarified 
because the part description is different in Boeing Alert Service 
Bulletin 737-30A1059, dated September 10, 2007, and Boeing Service 
Bulletin 737-30A1057, Revision 1, dated October 31, 2007 (referred to 
in the AD as the appropriate sources of service information for 
accomplishing the specified actions), and Rosemount Aerospace Service 
Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006 (referred to as 
an additional source of service information for determining the part 
and serial numbers of the windshield wiper motors). Boeing Alert 
Service Bulletin 737-30A1059, dated September 10, 2007, and Boeing 
Service Bulletin 737-30A1057, Revision 1, dated October 31, 2007, 
specify replacing the windshield wiper motor, and Rosemount Aerospace 
Service Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006, 
specifies replacing the power module of the windshield wiper motor. We 
disagree with using Boeing's suggested wording, which could result in 
confusion since the Boeing service bulletins specify replacing the 
motor instead of replacing the power module. We have changed Note 1 for 
clarification to include the description specified in Rosemount 
Aerospace Service Bulletin 2313M-347/2313M-348-30-01, dated June 30, 
2006.

Request for Credit for Previously Accomplished Actions

    Boeing also asks that we change paragraph (h) of the NPRM to 
include credit for Model 737-400 and -500 series airplanes on which the 
actions specified in Boeing Alert Service Bulletin 737-30A1059, dated 
September 10, 2007, were done before the effective date of the AD. 
Boeing states that Boeing Alert Service Bulletin 737-30A1059, dated 
September 10, 2007, provides instructions for corrective action for 
those airplanes.
    We acknowledge and agree with Boeing's intent that credit should be 
given for actions done before the effective date of the AD. However, we 
do not agree to include credit for using the original issue of the 
service bulletin to do the actions specified in paragraph (h) of the 
AD. Boeing Alert Service Bulletin 737-30A1059, dated September 10, 
2007, is already referred to in paragraph (f) of this AD as the 
appropriate source of service information for accomplishing the 
inspection and corrective actions for Model 737-400 and -500 series 
airplanes. Paragraph (e) of the AD specifies that compliance with the 
AD before the effective date (comply within the compliance times 
specified unless already done) meets the requirements of the AD. We 
have made no change to the AD in this regard.

Requests To Clarify Requirements for Maintenance Record Review and Re-
Identifying the Wiper Motor Part Number

    Southwest Airlines (SWA), KLM Fleet Services, and Airtran Airways 
request clarification of the review of airplane maintenance records and 
reidentification of the wiper motor part number, as specified in 
paragraph (f) of the NPRM.
    SWA asks why the wiper motor must be re-identified while on the 
airplane since the review of airplane maintenance records is acceptable 
in lieu of an on-airplane inspection of the wiper motor part number and 
serial number. SWA also notes that the referenced service information 
requires operators to re-identify the part number of a wiper motor that 
has been determined to be in good and acceptable working condition. SWA 
states that re-identifying the part number would be more efficient and 
convenient if it could be done at the manufacturing facility during 
maintenance when the motor is removed for another reason.
    KLM states that it is unclear if it is still mandatory to re-
identify the wiper motor part number within the 60-month compliance 
time after reviewing the maintenance records, knowing that the wiper 
motor serial numbers are outside the affected modification range 
specified in Rosemount Aerospace Service Bulletin 2313M-347/2313M-348-
30-01, dated June 30, 2006. KLM adds that intensive work is necessary 
if the wiper motor must be re-identified even if it is not affected.
    AirTran reiterates the views of SWA and KLM and adds that units 
with replaced modules have eliminated the unsafe condition described in 
the NPRM. AirTran states that the wiper

[[Page 71543]]

motors are located in a difficult location to view or access, and they 
cannot be re-identified while installed. AirTran notes that gaining 
access to the airplane, removing the wiper motor, re-identifying the 
motor, and re-installing the motor is an undue burden on the airlines, 
since the re-identification does not improve the safety of the 
airplane. AirTran suggests that the final rule specify that, for 
airplanes having a wiper motor module that has been replaced, as 
indicated in Appendix A of Rosemount Aerospace Service Bulletin 2313M-
347/2313M-348-30-01, dated June 30, 2006, the part number may be 
changed at the next shop visit, as opposed to changing the part number 
in service.
    We agree with the commenters' concerns. Operators may review the 
maintenance records to comply with the AD during the 60-month 
compliance time proposed in the NPRM, as long as applicable corrective 
actions are also done in that time. In light of the comments provided, 
we have determined that, in this case, if the wiper motor is not 
affected by the requirements of the AD, re-identifying the wiper motor 
part number is not necessary to ensure an acceptable level of safety. 
Operators should not be required to remove and replace a part if it is 
deemed to be an acceptable part. We have added this clarification to 
paragraph (f) of this AD accordingly.

Request for Clarification of Wiper Motor Replacement Requirement

    SWA asks that the wiper motor replacement be required only if the 
part number and serial number cannot be read or are listed in Appendix 
A of Rosemount Aerospace Service Bulletin 2313M-347/2313M-348-30-01, 
dated June 30, 2006, with the ``Module Completed'' column marked as 
``No'' (as specified in Steps 1.a. and 1.d., Section 3.B.--Work 
Instructions) of Boeing Service Bulletin 737-30A1057, Revision 1, dated 
October 31, 2007.
    We agree with SWA. The procedures specified in Steps 1.a. and 1.d. 
(and in Steps 2.a. and 2.d.) of the Work Instructions already specify 
replacement of the wiper motor if the part number and serial number 
cannot be read or are listed in Appendix A of Rosemount Aerospace 
Service Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006, with 
the ``Module Completed'' column marked as ``No''. The procedures in 
Steps 1.b. and 1.c. of the Work Instructions specify re-identification 
of the part if the part number and serial number are not listed in 
Appendix A or are listed in Appendix A of Rosemount Aerospace Service 
Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006, with the 
``Module Completed'' column marked as ``Yes.'' The replacement is 
required only if it meets the conditions specified in Boeing Service 
Bulletin 737-30A1057, Revision 1, dated October 31, 2007, Steps 1.a. 
and 1.d. (or Steps 2.a. and 2.d.), of the Work Instructions. Therefore, 
we have made no change to the AD in this regard.

Request To Clarify Certain Part Numbers in Paragraphs (g) and (i) of 
the NPRM

    Air Transport Association (ATA) on behalf of its member Delta 
Airlines states that the part numbers specified in paragraphs (g) and 
(i) of the NPRM have variations (P/N 2313M347-3 or P/N 2313M348-3), 
which should be noted in those paragraphs.
    We agree with the commenters because the part numbers are the same, 
the variation is only in the dashes; therefore we have added those 
alternate part numbers to paragraphs (g) and (i) of this AD for 
clarification.

Request To Correct Typographical Error in Rosemount Service Bulletin

    ATA on behalf of its member Delta Airlines states that Rosemount 
Aerospace Service Bulletin 2313M-347/2313M-348-30-01, dated June 30, 
2006, has a typographical error in Appendix A as follows: For Model 
Number 2313M-348-3, serial number (S/N) ``M252'' should be S/N 
``M0252.'' Delta adds that this determination was made in cooperation 
with Rosemount.
    Based on the information provided by the commenter, and 
confirmation from Rosemount Aerospace, we agree that the serial number 
specified in Appendix A of Rosemount Aerospace Service Bulletin 2313M-
347/2313M-348-30-01, dated June 30, 2006, is incorrect. We have added a 
new Note 2 to this AD to clarify the correct serial number as follows: 
For Model Number 2313M-348-3, S/N ``M252'' should be S/N ``M0252.'' We 
have been informed that Rosemount Aerospace Service Bulletin 2313M-347/
2313M-348-30-01, dated June 30, 2006, is being revised and the correct 
serial number will be included in the revision.

Request To Clarify Certain Requirements in Boeing Service Bulletin

    ATA on behalf of its member Delta Airlines states that Boeing 
Service Bulletin 737-30A1057, dated October 6, 2006, referred to an 
incorrect airplane maintenance manual (AMM) section for the Windshield 
Wiper Motor System Operational Test. In addition, that service bulletin 
did not provide wiper motor condition information in the Work 
Instructions. That information was provided only in the Compliance 
section of Boeing Service Bulletin 737-30A1057, dated October 6, 2006.
    We infer that the commenters are asking that paragraph (h) of the 
NPRM be revised to note these corrections; we agree with the 
commenters. There were mistakes in Boeing Service Bulletin 737-30A1057, 
dated October 6, 2006, which were corrected in Boeing Service Bulletin 
737-30A1057, Revision 1, dated October 31, 2007 (referred to in the AD 
as the appropriate source of service information for accomplishing the 
actions). The commenter states that it identified and incorporated the 
changes, which resulted in the issuance of Boeing Service Bulletin 737-
30A1057, Revision 1, dated October 31, 2007. The AMM section specified 
accomplishing the operational test in Boeing Alert Service Bulletin 
737-30A1057, dated October 6, 2006, is AMM 30-42-21/501; the correct 
AMM section specified for accomplishing the operational test in Boeing 
Service Bulletin 737-30A1057, Revision 1, dated October 31, 2007, is 
AMM 30-42-00/501. We have clarified paragraph (h) of this AD to refer 
to Boeing Service Bulletin 737-30A1057, Revision 1, dated October 31, 
2007, to ensure that the mistakes in the original issue of the service 
bulletin have been addressed.

Request To Extend Compliance Time

    ATA on behalf of its member American Airlines (AAL) notes concern 
with the 60-month compliance time specified for accomplishing the 
actions specified in the NPRM. AAL states that its standard maintenance 
interval is 72 months; therefore, a 60-month compliance time could 
unnecessarily drive up out-of-service time and related costs. AAL 
recommends that we extend the compliance time to 72 months to align 
with industry standard material review board task intervals.
    We do not agree to extend the compliance time. In developing an 
appropriate compliance time for this action, we considered the urgency 
associated with the subject unsafe condition, the availability of 
required parts, and the practical aspect of accomplishing the required 
actions within a period of time that corresponds to the normal 
scheduled maintenance for most affected operators. In light of these 
items, we have determined that a 60-month compliance time is 
appropriate. However, under the provisions of paragraph (j) of the AD, 
we will consider requests to adjust the compliance time if sufficient 
data are submitted to substantiate that the new

[[Page 71544]]

compliance time would provide an acceptable level of safety. We have 
made no change to the AD in this regard.

Request To Allow an Alternative Method for Part Number Marking

    SWA asks that another method of part marking be included in the 
NPRM. SWA asks why ``classification RO'' (Rubber Stamp Only per 
BAC5307) must be used to change the part number on the wiper motor. SWA 
asks that the NPRM allow another form of acceptable marking for the 
part number, such as permanent marker.
    We agree that any permanent method of part marking is acceptable. 
We have added a new Note 3 to this AD to clarify that any permanent 
method is acceptable.

Request To Change Parts Installation Paragraph

    WestJet asks that paragraph (i) of the NPRM (Parts Installation) be 
changed as follows: ``As of the effective date of this AD, no person 
may install on any aircraft a Rosemount Aerospace windshield wiper 
motor having P/N 2313M-347-3 or P/N 2313M-348-3 that has a serial 
number that is listed in Rosemount Aerospace Service Bulletin 2313M-
347/2313M-348-30-01.'' WestJet states that windshield wiper motors 
having P/N 2313M-347-3 and P/N 2313M-348-3 with serial numbers outside 
of the affected modification range, that have not yet been ``re-
labeled'' per Rosemount Aerospace Service Bulletin 2313M-347/2313M-348-
30-01, dated June 30, 2006, may be installed on any aircraft. WestJet 
adds that this change would allow operators to install a ``mechanically 
serviceable'' part (that has not yet been ``re-labeled'') on an 
aircraft.
    We do not agree to change paragraph (h) of the AD. Common industry 
practice is to control part configuration by part number, not by serial 
number. While we already agreed that it is not necessary to remove 
parts from the airplane just to revise the part numbers, we do not 
agree that it is acceptable to install the subject replacement parts 
without revising the part number. Ensuring that only parts with correct 
part numbers are installed on the airplane is an important part of 
maintaining configuration control and safe operation of the fleet. We 
have made no change to the AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We also determined that 
these changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 767 airplanes of U.S. registry. We 
also estimate that it takes about 1 work-hour per product to comply 
with the inspection. The average labor rate is $80 per work-hour. Based 
on these figures, we estimate the cost of this AD to the U.S. operators 
to be $61,360 or $80 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 airplane 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

    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), 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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.

windshield wipers stopped working in flight. We are issuing this AD 
to prevent failure of the windshield wipers in wet weather, which 
could result in decreased visibility for the flightcrew.

Compliance

    (e) Comply with this AD within the compliance times specified, 
unless already done.

Inspection and Corrective Actions if Necessary

    (f) Except as provided by paragraph (g) of this AD: Within 60 
months after the effective date of this AD, inspect to determine the 
part number and serial number of the windshield wiper motors for the 
pilot's and first officer's windshields, and do all applicable 
corrective actions, by accomplishing all of the applicable actions 
specified in the Accomplishment Instructions of Boeing Alert Service 
Bulletin 737-30A1059, dated September 10, 2007 (for Model 737-400 
and -500 series airplanes); or Boeing Service Bulletin 737-30A1057, 
Revision 1, dated October 31, 2007 (for Model 737-600, -700,

[[Page 71545]]

-700C, -800, and -900 series airplanes); as applicable. A review of 
airplane maintenance records is acceptable in lieu of the inspection 
required by paragraph (f) of this AD if the part number and serial 
number of the windshield wiper motors can be conclusively determined 
from that review. Following the inspection or records review, as 
applicable, for any windshield wiper motor that is found not to be 
affected by the requirements of this AD, re-identifying the part 
number is not required.

    Note 1: Boeing Alert Service Bulletin 737-30A1059, dated 
September 10, 2007; and Boeing Service Bulletin 737-30A1057, 
Revision 1, dated October 31, 2007; refer to Rosemount Aerospace 
Service Bulletin 2313M-347/2313M-348-30-01, dated June 30, 2006, as 
an additional source of service information for determining whether 
the windshield wiper motor (identified in the Rosemount service 
bulletin as the ``power module'') has been previously replaced and 
for changing the part number.


    Note 2: Appendix A of Rosemount Aerospace Service Bulletin 
2313M-347/2313M-348-30-01, dated June 30, 2006, identifies an 
incorrect serial number for Model Number 2313M-348-3. Serial number 
M252'' should be M0252.


    Note 3: Rosemount Aerospace Service Bulletin 2313M-347/2313M-
348-30-01, dated June 30, 2006, specifies marking affected parts 
with an approved opaque material per BAC5307, classification RO, 
with an approved permanent marking material; however, for the 
purposes of this AD, any permanent method of part marking is 
acceptable.
