ACTION: Notice of proposed rulemaking (NPRM). WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 767 airplanes. The existing AD currently requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, and corrective actions if necessary. This proposed AD would expand the inspection area to include the vertical inner chord at STA 1809.5. This proposed AD results from reported fatigue cracking in the vertical inner chord and the forward outer chord while doing the detailed inspection of the horizontal inner chord at STA 1809.5. We are proposing this AD to detect and correct fatigue cracking in the bulkhead structure at STA 1809.5 and the vertical inner chord at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane. DATES: We must receive comments on this proposed AD by March 25, 2010. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

PO 00000 Frm 00024 Fmt 4702 Sfmt 4702 Discussion On November 9, 2006, we issued AD 2006–24–04, Amendment 39–14833 (71 FR 68432, November 27, 2006), for all Model 767 airplanes. That AD requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, and corrective actions if necessary. That AD resulted from fatigue cracks found in the forward outer chord and horizontal inner chord at STA 1809.5. We issued that AD to detect and correct cracking in the bulkhead structure at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane. Actions Since Existing AD Was Issued Since we issued AD 2006–24–04, an operator reported fatigue cracking in the vertical inner chord found while doing the detailed inspection of the horizontal inner chord required by that AD. A surface HFEC inspection was done to confirm the crack. The crack was found on the right side of the structure at a fastener hole near buttock line (BL) 28.5, water line (WL) 257, common to both the horizontal and vertical inner chord. The vertical inner chord crack was found on an airplane with 28,234 total flight cycles. Relevant Service Information AD 2006–24–04 refers to Boeing Alert Service Bulletin 767–53A0131, dated March 30, 2006, as the appropriate source of service information for the required actions. We have reviewed Boeing Alert Service Bulletin 767– 53A0131, Revision 1, dated March 12, 2009. Revision 1 adds a surface HFEC inspection for the vertical inner chord, and clarifies the procedures for inspecting the horizontal inner chord. The service bulletin specifies a compliance time of before 15,000 total flight cycles or within 6,000 flight cycles after the previous PARTS 1–4 inspection, whichever occurs first, for the surface HFEC inspection for the vertical inner chord. The service bulletin also specifies a repeat interval 6,000 flight cycles thereafter for the surface HFEC inspection for the vertical inner chord. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to develop on other airplanes of the same type design. For this reason, we are proposing this AD, which would supersede AD 2006– E:\FR\FM\08FEP1.SGM 08FEP1 6155 Federal Register / Vol. 75, No. 25 / Monday, February 8, 2010 / Proposed Rules 24–04 and retain the requirements of the existing AD. This proposed AD would also require accomplishing the new actions specified in the revised service bulletin described previously. Change to Paragraph (i) of the Existing AD We have revised paragraph (i) of the existing AD to clarify that the modification of a forward outer chord may be done in accordance with Steps 4.A through 4.C and 4.G through 4.P of Repair 9, dated April 15, 2006, of Chapter 53–80–08 of the Boeing 767– 200 Structural Repair Manual (SRM), Document D634T201; Boeing 767–300 SRM, Document D634T210; Boeing 767–300F SRM, Document D634T215; or Boeing 767–400 SRM, Document D634T225; as applicable. For a horizontal inner chord, modification may be done in accordance with Steps 4.A, 4.B, and 4.F through 4.P of Repair 10, dated April 15, 2006, of Chapter 53– 80–08 of the Boeing 767–200 SRM, Document D634T201; Boeing 767–300 SRM, Document D634T210; Boeing 767–300F SRM, Document D634T215; or Boeing 767–400 SRM, Document D634T225; as applicable. Change to Paragraph (j)(3) of the Existing AD Boeing Commercial Airplanes has received an Organization Designation Authorization (ODA), which replaces their previous designation as a Delegation Option Authorization (DOA) holder. We have revised paragraph (j)(3) of the existing AD (paragraph (n)(3) of this AD) to delegate the authority to approve an alternative method of compliance for any repair required by this AD to the Boeing Commercial Airplanes ODA. Costs of Compliance There are about 975 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Repetitive inspections of STA 1805.5 (required by AD 2006–24–04). Inspection of inner chord (new proposed action). WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS Jkt 220001 Number of U.S.-registered airplanes Cost per airplane $960 per inspection cycle. $160 per inspection cycle. $80 None ........ 2 Regulatory Findings We have 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 that the proposed regulation: 11:50 Feb 05, 2010 Parts 12 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. VerDate Nov<24>2008 Average labor rate per hour Work hours Action $80 None ........ 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); 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to all Model 767 airplanes. The existing AD 
currently requires repetitive detailed and high frequency eddy current 
(HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking, 
and corrective actions if necessary. This proposed AD would expand the 
inspection area to include the vertical inner chord at STA 1809.5. This 
proposed AD results from reported fatigue cracking in the vertical 
inner chord and the forward outer chord while doing the detailed 
inspection of the horizontal inner chord at STA 1809.5. We are 
proposing this AD to detect and correct fatigue cracking in the 
bulkhead structure at STA 1809.5 and the vertical inner chord at STA 
1809.5, which could result in failure of the bulkhead structure for 
carrying the flight loads of the horizontal stabilizer, and consequent 
loss of controllability of the airplane.

DATES: We must receive comments on this proposed AD by March 25, 2010.

Discussion

    On November 9, 2006, we issued AD 2006-24-04, Amendment 39-14833 
(71 FR 68432, November 27, 2006), for all Model 767 airplanes. That AD 
requires repetitive detailed and high frequency eddy current (HFEC) 
inspections of the station (STA) 1809.5 bulkhead for cracking, and 
corrective actions if necessary. That AD resulted from fatigue cracks 
found in the forward outer chord and horizontal inner chord at STA 
1809.5. We issued that AD to detect and correct cracking in the 
bulkhead structure at STA 1809.5, which could result in failure of the 
bulkhead structure for carrying the flight loads of the horizontal 
stabilizer, and consequent loss of controllability of the airplane.

Actions Since Existing AD Was Issued

    Since we issued AD 2006-24-04, an operator reported fatigue 
cracking in the vertical inner chord found while doing the detailed 
inspection of the horizontal inner chord required by that AD. A surface 
HFEC inspection was done to confirm the crack. The crack was found on 
the right side of the structure at a fastener hole near buttock line 
(BL) 28.5, water line (WL) 257, common to both the horizontal and 
vertical inner chord. The vertical inner chord crack was found on an 
airplane with 28,234 total flight cycles.

Relevant Service Information

    AD 2006-24-04 refers to Boeing Alert Service Bulletin 767-53A0131, 
dated March 30, 2006, as the appropriate source of service information 
for the required actions. We have reviewed Boeing Alert Service 
Bulletin 767-53A0131, Revision 1, dated March 12, 2009. Revision 1 adds 
a surface HFEC inspection for the vertical inner chord, and clarifies 
the procedures for inspecting the horizontal inner chord. The service 
bulletin specifies a compliance time of before 15,000 total flight 
cycles or within 6,000 flight cycles after the previous PARTS 1-4 
inspection, whichever occurs first, for the surface HFEC inspection for 
the vertical inner chord. The service bulletin also specifies a repeat 
interval 6,000 flight cycles thereafter for the surface HFEC inspection 
for the vertical inner chord.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to develop on other airplanes of the 
same type design. For this reason, we are proposing this AD, which 
would supersede AD 2006-

[[Page 6155]]

24-04 and retain the requirements of the existing AD. This proposed AD 
would also require accomplishing the new actions specified in the 
revised service bulletin described previously.

Change to Paragraph (i) of the Existing AD

    We have revised paragraph (i) of the existing AD to clarify that 
the modification of a forward outer chord may be done in accordance 
with Steps 4.A through 4.C and 4.G through 4.P of Repair 9, dated April 
15, 2006, of Chapter 53-80-08 of the Boeing 767-200 Structural Repair 
Manual (SRM), Document D634T201; Boeing 767-300 SRM, Document D634T210; 
Boeing 767-300F SRM, Document D634T215; or Boeing 767-400 SRM, Document 
D634T225; as applicable. For a horizontal inner chord, modification may 
be done in accordance with Steps 4.A, 4.B, and 4.F through 4.P of 
Repair 10, dated April 15, 2006, of Chapter 53-80-08 of the Boeing 767-
200 SRM, Document D634T201; Boeing 767-300 SRM, Document D634T210; 
Boeing 767-300F SRM, Document D634T215; or Boeing 767-400 SRM, Document 
D634T225; as applicable.

Change to Paragraph (j)(3) of the Existing AD

    Boeing Commercial Airplanes has received an Organization 
Designation Authorization (ODA), which replaces their previous 
designation as a Delegation Option Authorization (DOA) holder. We have 
revised paragraph (j)(3) of the existing AD (paragraph (n)(3) of this 
AD) to delegate the authority to approve an alternative method of 
compliance for any repair required by this AD to the Boeing Commercial 
Airplanes ODA.

Costs of Compliance

    There are about 975 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this proposed AD.

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 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 that the 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); 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
