SUPPLEMENTARY INFORMATION: pmangrum on DSK3VPTVN1PROD with PROPOSALS-1 Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2013–0547; Directorate Identifier 2013– NM–028–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each VerDate Mar<15>2010 14:53 Jul 17, 2013 Jkt 229001 substantive verbal contact we receive about this proposed AD. Discussion As described in FAA Advisory Circular 120–104 (https://www.faa.gov/ documentLibrary/media/ Advisory_Circular/120-104.pdf), several programs have been developed to support initiatives that will ensure the continued airworthiness of aging airplane structure. The last element of those initiatives is the requirement to establish a LOV of the engineering data that support the structural maintenance program under 14 CFR 26.21. This AD is the result of an assessment of the previously established programs by Boeing during the process of establishing the LOV for Boeing Model 727 series airplanes. The action specified in this proposed AD is necessary to complete certain programs to ensure the continued airworthiness of aging airplane structure and to support an airplane reaching its LOV. We have received reports of cracks in the pressure floor of the main landing gear (MLG) wheel wells. Three operators reported cracks from 25 to 48 inches long, resulting in rapid decompression of the airplane. Twenty-four operators reported 67 airplanes with cracks up to two inches located in the reinforcing beads on both sides of the frame. This fatigue cracking, if not corrected, could result in rapid loss of cabin pressurization. Relevant Service Information We reviewed Boeing Service Bulletin 727–53A0124, Revision 3, dated November 30, 1989. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for Docket No. FAA–2013–0547. ‘‘Preventive Modification,’’ of the Accomplishment Instructions of the service information described previously. The phrase ‘‘related investigative actions’’ is used in this proposed AD. ‘‘Related investigative actions’’ are follow-on actions that: (1) Are related to the primary actions, and (2) are actions that further investigate the nature of any condition found. Related investigative actions in an AD could include, for example, inspections. In addition, the phrase ‘‘corrective actions’’ is used in this proposed AD. ‘‘Corrective actions’’ are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs. Differences Between the Proposed AD and the Service Information Prior to accomplishing the preventive modification, this proposed AD would require a one-time inspection of the pressure floor for cracks in both the right and left main wheel wells, and corrective actions if necessary, in lieu of the repetitive inspections specified in Boeing Service Bulletin 727–53A0124, Revision 3, dated November 30, 1989. The repetitive inspections are addressed by AD 91–22–08, Amendment 39–8068 (56 FR 57233, November 8, 1991). Additionally, the applicability of this proposed AD is different than the effectivity described in Boeing Service Bulletin 727–53A0124, Revision 3, dated November 30, 1989. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Explanation of Compliance Time The compliance time for the modification specified in this proposed AD for addressing WFD was established to ensure that discrepant structure is modified before WFD develops in airplanes. Standard inspection techniques cannot be relied on to detect WFD before it becomes a hazard to flight. We will not grant any extensions of the compliance time to complete any AD-mandated service bulletin related to WFD without extensive new data that would substantiate and clearly warrant such an extension. Proposed AD Requirements This proposed AD would require a one-time eddy current inspection, penetrant inspection, or detailed inspection for cracking of the pressure floor of both main wheel wells as described in Part I, ‘‘Inspection,’’ of the Accomplishment Instructions of the service information described previously, and related investigative and corrective actions if necessary; and would also require accomplishing the modification specified in Part III, Related Rulemaking AD 90–06–09, Amendment 39–6488 (55 FR 8370, March 7, 1990), requires accomplishing the preventive modification specified in Boeing Alert Service Bulletin 727–53A0124, Revision 2, dated May 2, 1975, for airplane line numbers 1 through 1102 inclusive. AD 91–22–08, Amendment 39–8068 (56 FR 57233, November 8, 1991), requires compliance with the inspection and repair, if necessary specified in Boeing Service Bulletin 727–53A0124, Revision PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 E:\FR\FM\18JYP1.SGM 18JYP1 Federal Register / Vol. 78, No. 138 / Thursday, July 18, 2013 / Proposed Rules 3, dated November 30, 1989, for airplane line numbers 1 through 1832 inclusive, but does not require the preventive modification. Costs of Compliance We estimate that this proposed AD affects 94 airplanes of U.S. registry. 42897 We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Inspection and Modification .... 222 work-hours × $85 per hour = $18,870 ............................ We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Authority for This Rulemaking The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 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. pmangrum on DSK3VPTVN1PROD with PROPOSALS-1 Regulatory Findings We 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 this 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), (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.

The MCAI states: Large aeroplane incidents and accidents have occurred because of fuel tank low level situations, or because of fuel starvation, resulting in one or several engine(s) flameout. The results of the investigation into an ATR 72 accident in August 2005 have shown that overruling standard operational procedures and maintenance practices have led to this kind of occurrence.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 727-200 and 727-200F series airplanes. 
This proposed AD is intended to complete certain mandated programs 
intended to support the airplane reaching its limit of validity (LOV) 
of the engineering data that support the established structural 
maintenance program. This proposed AD would require a one-time 
inspection for cracking of the pressure floor of both main wheel wells, 
and related investigative and corrective actions if necessary; and 
would require modifying the pressure floor of both main wheel wells. We 
are proposing this AD to prevent fatigue cracking in the pressure floor 
of the main wheel wells, which could lead to rapid loss of cabin 
pressurization.

DATES: We must receive comments on this proposed AD by September 3, 
2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    As described in FAA Advisory Circular 120-104 (https://www.faa.gov/documentLibrary/media/Advisory_Circular/120-104.pdf), several programs 
have been developed to support initiatives that will ensure the 
continued airworthiness of aging airplane structure. The last element 
of those initiatives is the requirement to establish a LOV of the 
engineering data that support the structural maintenance program under 
14 CFR 26.21. This AD is the result of an assessment of the previously 
established programs by Boeing during the process of establishing the 
LOV for Boeing Model 727 series airplanes. The action specified in this 
proposed AD is necessary to complete certain programs to ensure the 
continued airworthiness of aging airplane structure and to support an 
airplane reaching its LOV.
    We have received reports of cracks in the pressure floor of the 
main landing gear (MLG) wheel wells. Three operators reported cracks 
from 25 to 48 inches long, resulting in rapid decompression of the 
airplane. Twenty-four operators reported 67 airplanes with cracks up to 
two inches located in the reinforcing beads on both sides of the frame. 
This fatigue cracking, if not corrected, could result in rapid loss of 
cabin pressurization.

Relevant Service Information

    We reviewed Boeing Service Bulletin 727-53A0124, Revision 3, dated 
November 30, 1989. For information on the procedures and compliance 
times, see this service information at https://www.regulations.gov by 
searching for Docket No. FAA-2013-0547.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require a one-time eddy current inspection, 
penetrant inspection, or detailed inspection for cracking of the 
pressure floor of both main wheel wells as described in Part I, 
``Inspection,'' of the Accomplishment Instructions of the service 
information described previously, and related investigative and 
corrective actions if necessary; and would also require accomplishing 
the modification specified in Part III, ``Preventive Modification,'' of 
the Accomplishment Instructions of the service information described 
previously.
    The phrase ``related investigative actions'' is used in this 
proposed AD. ``Related investigative actions'' are follow-on actions 
that: (1) Are related to the primary actions, and (2) are actions that 
further investigate the nature of any condition found. Related 
investigative actions in an AD could include, for example, inspections.
    In addition, the phrase ``corrective actions'' is used in this 
proposed AD. ``Corrective actions'' are actions that correct or address 
any condition found. Corrective actions in an AD could include, for 
example, repairs.

Differences Between the Proposed AD and the Service Information

    Prior to accomplishing the preventive modification, this proposed 
AD would require a one-time inspection of the pressure floor for cracks 
in both the right and left main wheel wells, and corrective actions if 
necessary, in lieu of the repetitive inspections specified in Boeing 
Service Bulletin 727-53A0124, Revision 3, dated November 30, 1989. The 
repetitive inspections are addressed by AD 91-22-08, Amendment 39-8068 
(56 FR 57233, November 8, 1991). Additionally, the applicability of 
this proposed AD is different than the effectivity described in Boeing 
Service Bulletin 727-53A0124, Revision 3, dated November 30, 1989.

Explanation of Compliance Time

    The compliance time for the modification specified in this proposed 
AD for addressing WFD was established to ensure that discrepant 
structure is modified before WFD develops in airplanes. Standard 
inspection techniques cannot be relied on to detect WFD before it 
becomes a hazard to flight. We will not grant any extensions of the 
compliance time to complete any AD-mandated service bulletin related to 
WFD without extensive new data that would substantiate and clearly 
warrant such an extension.

Related Rulemaking

    AD 90-06-09, Amendment 39-6488 (55 FR 8370, March 7, 1990), 
requires accomplishing the preventive modification specified in Boeing 
Alert Service Bulletin 727-53A0124, Revision 2, dated May 2, 1975, for 
airplane line numbers 1 through 1102 inclusive. AD 91-22-08, Amendment 
39-8068 (56 FR 57233, November 8, 1991), requires compliance with the 
inspection and repair, if necessary specified in Boeing Service 
Bulletin 727-53A0124, Revision

[[Page 42897]]

3, dated November 30, 1989, for airplane line numbers 1 through 1832 
inclusive, but does not require the preventive modification.

Costs of Compliance

    We estimate that this proposed AD affects 94 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection and Modification........  222 work[dash]hours x $85            $2,906         $21,776      $2,046,944
                                      per hour = $18,870.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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 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 this 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),
    (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.
