ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 767–200, –300, and –300F series airplanes. This AD requires repetitive inspections for fatigue cracking and corrosion of the upper link E:\FR\FM\01OCR1.SGM 01OCR1 Federal Register / Vol. 74, No. 189 / Thursday, October 1, 2009 / Rules and Regulations fuse pin of the nacelle struts, and related investigative and corrective actions if necessary. This AD also provides terminating action for the repetitive inspections. This AD results from two reports of cracked upper link fuse pins. We are issuing this AD to prevent fatigue cracking or corrosion of the upper link fuse pin, which could result in failure of the fuse pin and consequent reduced structural integrity of the nacelle strut and possible separation of the strut and engine from the airplane during flight.

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 767–200, –300, and –300F series airplanes. That NPRM was published in the Federal Register on January 12, 2009 (74 FR 1155). That NPRM proposed to require repetitive inspections for fatigue cracking and corrosion of the upper link fuse pin of VerDate Nov<24>2008 17:06 Sep 30, 2009 Jkt 217001 the nacelle struts, and related investigative and corrective actions if necessary. That NPRM also proposed to provide terminating action for the repetitive inspections. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Support for the AD Boeing concurs with the content of the NPRM. Air Transport Association (ATA) on behalf of its members Delta Airlines and United Airlines (UAL) agrees with the intent of the NRPM, and provides the following recommendations from its members. Request to Add a Note of Clarification Delta asks that we revise the NPRM to include a note in the AD which specifies that the upper link inspections can be done with the pylon and/or engine in any position. Delta states that Boeing Alert Service Bulletin 767– 54A0074, Revision 1, dated April 24, 2008, specifies doing a visual inspection with ‘‘the fuse pin in place, without engine removal and strut removal.’’ Delta notes that there are times when engines or pylons are removed for other reasons, and it would prefer not to wait until the engine and strut are reinstalled. Delta states that the procedures specified in Boeing Alert Service Bulletin 767–54A0074, Revision 1, dated April 24, 2008, allow fuse pin inspections with the engines and pylons in any position. Delta adds that related service information, Boeing Telex 1– 1154785301, dated January 21, 2009 (released after the NPRM was issued), specifies that the upper link inspections can be done with the pylon and/or engine in any position. We agree with the commenter’s request. For the reasons provided by Delta, we have included a new Note 1 after paragraph (f) of this AD to specify that the upper link inspections can be done with the pylon and/or engine in any position. Request to Define ‘‘References’’ Delta asks that we revise the NPRM to include a note to clarify that the ‘‘References’’ column in the table in Figure 2 of Boeing Alert Service Bulletin 767–54A0074, Revision 1, dated April 24, 2008, should be treated as ‘‘refer to’’ material (which is information that provides guidance for using related procedures), as defined in Note 9 of paragraph 3.A. of that service bulletin. Delta points out that the procedures in Boeing Telex 1–1154785301, dated January 21, 2009, specify that the PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 50693 airplane maintenance manual (AMM) and standard operating procedures manual (SOPM) are identified in the ‘‘References’’ column of that table as ‘‘refer to’’ material so that operator equivalent procedures may be used. We agree that the material in the ‘‘References’’ column in the table in Figure 2 of Boeing Alert Service Bulletin 767–54A0074, Revision 1, dated April 24, 2008, refers to the procedures in the specified manuals and should be treated as guidance for using related procedures. However, to add a note to this AD could be confusing because none of the paragraphs in the AD refer to the procedures in those manuals. Therefore, we have made no change to the AD in this regard. Request to Add a Note Clarifying Application of Primer Delta asks that we revise the NPRM to include a note to clarify that reapplication of primer in accordance with Steps 4.b.(1) and 4.b.(2) of the Accomplishment Instructions of Boeing Alert Service Bulletin 767–54A0074, Revision 1, dated April 24, 2008, is necessary only to touch up bare areas of the fuse pin. Delta states that paragraph 3.B, Step 4.b., of the Accomplishment Instructions of Boeing Alert Service Bulletin 767–54A0074, Revision 1, dated April 24, 2008, specifies applying two coats of Boeing Material Specification (BMS) 10–11 primer after each inspection if no cracks are found during the inspection. Delta notes that the procedure does not specify ‘‘touching up primer’’ but rather applying two coats each time. Delta adds that since the repeat inspection interval is much shorter, the fuse pin will have ten coats of primer built up over the next ten years, and asserts that the inspection cannot be done through ten coats of primer. Delta points out that Boeing has confirmed in Boeing Telex 1–1154785301, dated January 21, 2009, that two coats of primer are required only to touch up bare areas on the fuse pin. We agree that clarification is necessary for the reasons provided by Delta. We have included a new Note 2 after paragraph (f) of this AD to specify that two coats of primer are necessary only to touch up bare areas of the fuse pin. Request to Provide Credit for Inspections Done Using Previous Service Information UAL asks that operators be given credit for inspections done before the effective date of the AD in accordance with Boeing Service Bulletin 767–54– 0074, dated March 27, 1997. UAL notes E:\FR\FM\01OCR1.SGM 01OCR1 50694 Federal Register / Vol. 74, No. 189 / Thursday, October 1, 2009 / Rules and Regulations that paragraph (h) of the NPRM provides credit for the replacement of fuse pins done in accordance with Boeing Service Bulletin 767–54–0074, dated March 27, 1997, but does not provide credit for the inspections, even though the procedures in the original issue and Revision 1 of the service bulletin are the same. We agree with the commenter. We have confirmed that inspections done before the effective date of this AD in accordance with Boeing Service Bulletin 767–54–0074, dated March 27, 1997, are acceptable for compliance with the inspection requirements of paragraph (f) of this AD. However, we point out that Boeing Service Bulletin 767–54–0074, dated March 27, 1997, allows the use of operator’s equivalent procedures, which Boeing Service Bulletin 767–54–0074, Revision 1, dated April 24, 2008, does not allow. Therefore, we have revised paragraph (h) of this AD to give credit for inspections done before the effective date of this AD in accordance with Boeing Service Bulletin 767–54–0074, dated March 27, 1997, provided that the inspection was not done using operator’s equivalent procedures. mstockstill on DSKH9S0YB1PROD with RULES Request to Clarify Certain Language in Paragraph (h) of the NPRM UAL suggests that paragraph (h) of the NPRM be revised to clarify the meaning of ‘‘corresponding requirements.’’ UAL states that paragraph (h) of the NPRM specifies that replacement of the fuse pins in accordance with Boeing Service Bulletin 767–54–0074, dated March 27, 1997, is acceptable for compliance with the ‘‘corresponding requirements’’ of this AD. UAL notes that the phrase ‘‘for compliance with the ‘corresponding requirements’ of this AD’’ is very vague. We agree that clarification is necessary for the reasons provided by the commenter. We have changed paragraph (h) of this AD to refer to paragraph (f) of this AD for the inspections and paragraph (g) of this AD for the modification. Request to Extend Grace Period Aeroflot asks that we increase the grace period for the inspections so that operators can prepare for accomplishment of the requirements in the AD. Aeroflot states that it is convenient to plan the work with common access SC-Checks, and adds that the NPRM gives a simple C-Check preparation period. Aeroflot states that this work has an economic impact with the time used in preparation and gaining access. We do not agree with the commenter’s request. In developing an appropriate compliance time for this AD, we considered not only the safety VerDate Nov<24>2008 17:06 Sep 30, 2009 Jkt 217001 implications, but the manufacturer’s recommendations, and the practical aspect of accomplishing the actions within an interval of time that corresponds to typical scheduled maintenance for affected operators. However, under the provisions of paragraph (i) of this AD, we may consider requests for adjustments to the compliance time if data are submitted to substantiate that such an adjustment would provide an acceptable level of safety. 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 354 airplanes of U.S. registry. We also estimate that it will take 4 work-hours per product to comply with this AD. The average labor rate is $80 per workhour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $113,280, or $320 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 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 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 PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 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.

corrective actions if necessary. This AD also provides terminating 
action for the repetitive inspections. This AD results from two reports 
of cracked upper link fuse pins. We are issuing this AD to prevent 
fatigue cracking or corrosion of the upper link fuse pin, which could 
result in failure of the fuse pin and consequent reduced structural 
integrity of the nacelle strut and possible separation of the strut and 
engine from the airplane during flight.

DATES: This AD is effective November 5, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 5, 
2009.

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 767-200, -300, and -300F series airplanes. That 
NPRM was published in the Federal Register on January 12, 2009 (74 FR 
1155). That NPRM proposed to require repetitive inspections for fatigue 
cracking and corrosion of the upper link fuse pin of the nacelle 
struts, and related investigative and corrective actions if necessary. 
That NPRM also proposed to provide terminating action for the 
repetitive inspections.

Comments

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

Support for the AD

    Boeing concurs with the content of the NPRM. Air Transport 
Association (ATA) on behalf of its members Delta Airlines and United 
Airlines (UAL) agrees with the intent of the NRPM, and provides the 
following recommendations from its members.

Request to Add a Note of Clarification

    Delta asks that we revise the NPRM to include a note in the AD 
which specifies that the upper link inspections can be done with the 
pylon and/or engine in any position. Delta states that Boeing Alert 
Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008, 
specifies doing a visual inspection with ``the fuse pin in place, 
without engine removal and strut removal.'' Delta notes that there are 
times when engines or pylons are removed for other reasons, and it 
would prefer not to wait until the engine and strut are reinstalled. 
Delta states that the procedures specified in Boeing Alert Service 
Bulletin 767-54A0074, Revision 1, dated April 24, 2008, allow fuse pin 
inspections with the engines and pylons in any position. Delta adds 
that related service information, Boeing Telex 1-1154785301, dated 
January 21, 2009 (released after the NPRM was issued), specifies that 
the upper link inspections can be done with the pylon and/or engine in 
any position.
    We agree with the commenter's request. For the reasons provided by 
Delta, we have included a new Note 1 after paragraph (f) of this AD to 
specify that the upper link inspections can be done with the pylon and/
or engine in any position.

Request to Define ``References''

    Delta asks that we revise the NPRM to include a note to clarify 
that the ``References'' column in the table in Figure 2 of Boeing Alert 
Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008, should 
be treated as ``refer to'' material (which is information that provides 
guidance for using related procedures), as defined in Note 9 of 
paragraph 3.A. of that service bulletin. Delta points out that the 
procedures in Boeing Telex 1-1154785301, dated January 21, 2009, 
specify that the airplane maintenance manual (AMM) and standard 
operating procedures manual (SOPM) are identified in the ``References'' 
column of that table as ``refer to'' material so that operator 
equivalent procedures may be used.
    We agree that the material in the ``References'' column in the 
table in Figure 2 of Boeing Alert Service Bulletin 767-54A0074, 
Revision 1, dated April 24, 2008, refers to the procedures in the 
specified manuals and should be treated as guidance for using related 
procedures. However, to add a note to this AD could be confusing 
because none of the paragraphs in the AD refer to the procedures in 
those manuals. Therefore, we have made no change to the AD in this 
regard.

Request to Add a Note Clarifying Application of Primer

    Delta asks that we revise the NPRM to include a note to clarify 
that re-application of primer in accordance with Steps 4.b.(1) and 
4.b.(2) of the Accomplishment Instructions of Boeing Alert Service 
Bulletin 767-54A0074, Revision 1, dated April 24, 2008, is necessary 
only to touch up bare areas of the fuse pin. Delta states that 
paragraph 3.B, Step 4.b., of the Accomplishment Instructions of Boeing 
Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 2008, 
specifies applying two coats of Boeing Material Specification (BMS) 10-
11 primer after each inspection if no cracks are found during the 
inspection. Delta notes that the procedure does not specify ``touching 
up primer'' but rather applying two coats each time. Delta adds that 
since the repeat inspection interval is much shorter, the fuse pin will 
have ten coats of primer built up over the next ten years, and asserts 
that the inspection cannot be done through ten coats of primer. Delta 
points out that Boeing has confirmed in Boeing Telex 1-1154785301, 
dated January 21, 2009, that two coats of primer are required only to 
touch up bare areas on the fuse pin.
    We agree that clarification is necessary for the reasons provided 
by Delta. We have included a new Note 2 after paragraph (f) of this AD 
to specify that two coats of primer are necessary only to touch up bare 
areas of the fuse pin.

Request to Provide Credit for Inspections Done Using Previous Service 
Information

    UAL asks that operators be given credit for inspections done before 
the effective date of the AD in accordance with Boeing Service Bulletin 
767-54-0074, dated March 27, 1997. UAL notes

[[Page 50694]]

that paragraph (h) of the NPRM provides credit for the replacement of 
fuse pins done in accordance with Boeing Service Bulletin 767-54-0074, 
dated March 27, 1997, but does not provide credit for the inspections, 
even though the procedures in the original issue and Revision 1 of the 
service bulletin are the same.
    We agree with the commenter. We have confirmed that inspections 
done before the effective date of this AD in accordance with Boeing 
Service Bulletin 767-54-0074, dated March 27, 1997, are acceptable for 
compliance with the inspection requirements of paragraph (f) of this 
AD. However, we point out that Boeing Service Bulletin 767-54-0074, 
dated March 27, 1997, allows the use of operator's equivalent 
procedures, which Boeing Service Bulletin 767-54-0074, Revision 1, 
dated April 24, 2008, does not allow. Therefore, we have revised 
paragraph (h) of this AD to give credit for inspections done before the 
effective date of this AD in accordance with Boeing Service Bulletin 
767-54-0074, dated March 27, 1997, provided that the inspection was not 
done using operator's equivalent procedures.

Request to Clarify Certain Language in Paragraph (h) of the NPRM

    UAL suggests that paragraph (h) of the NPRM be revised to clarify 
the meaning of ``corresponding requirements.'' UAL states that 
paragraph (h) of the NPRM specifies that replacement of the fuse pins 
in accordance with Boeing Service Bulletin 767-54-0074, dated March 27, 
1997, is acceptable for compliance with the ``corresponding 
requirements'' of this AD. UAL notes that the phrase ``for compliance 
with the `corresponding requirements' of this AD'' is very vague.
    We agree that clarification is necessary for the reasons provided 
by the commenter. We have changed paragraph (h) of this AD to refer to 
paragraph (f) of this AD for the inspections and paragraph (g) of this 
AD for the modification.

Request to Extend Grace Period

    Aeroflot asks that we increase the grace period for the inspections 
so that operators can prepare for accomplishment of the requirements in 
the AD. Aeroflot states that it is convenient to plan the work with 
common access SC-Checks, and adds that the NPRM gives a simple C-Check 
preparation period. Aeroflot states that this work has an economic 
impact with the time used in preparation and gaining access.
    We do not agree with the commenter's request. In developing an 
appropriate compliance time for this AD, we considered not only the 
safety implications, but the manufacturer's recommendations, and the 
practical aspect of accomplishing the actions within an interval of 
time that corresponds to typical scheduled maintenance for affected 
operators. However, under the provisions of paragraph (i) of this AD, 
we may consider requests for adjustments to the compliance time if data 
are submitted to substantiate that such an adjustment would provide an 
acceptable level of safety. 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 354 airplanes of U.S. registry. We 
also estimate that it will take 4 work-hours per product to comply with 
this AD. 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 
$113,280, or $320 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 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

    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.

    Note 1: The upper link inspections can be done with the pylon 
and/or engine in any position.


    Note 2: In paragraph 3.B, Steps 4.b.(1)(a) and 
4.b.(2)(b)2){a{time}  of the Accomplishment Instructions of Boeing 
Alert Service Bulletin 767-54A0074, Revision 1, dated April 24, 
2008, the procedures specify to apply two layers of Boeing Material 
Specification (BMS) 10-11 primer to the inside surface of the fuse 
pin if no crack indication is found. However, two layers of primer 
are only necessary to touch up bare areas on the fuse pin if no 
crack indication is found.
