SUPPLEMENTARY INFORMATION: sradovich on DSK3GMQ082PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain The Boeing Company Model 707–300, 707–300B, and 707– 300C series airplanes; and certain Model 727C, 727–100C, and 727–200F series airplanes. The NPRM published in the Federal Register on March 28, 2013 (78 FR 18922) (‘‘the NPRM’’). The NPRM was prompted by a report indicating that a cam latch on the MCD broke during flight. The NPRM proposed to require performing repetitive inspections of the MCD cam latches; VerDate Sep<11>2014 15:57 Dec 02, 2016 Jkt 241001 replacing cam latches, certain bolts, and door hinge fittings; performing related investigative and corrective actions, if necessary; and rigging the MCD. We are issuing this AD to detect and correct discrepancies of the cam latches, latch pins, and latch pin cross bolts, which could reduce the structural integrity of the MCD, and result in potential loss of the cargo door and rapid decompression of the airplane. Actions Since the NPRM Was Issued Since we issued the NPRM, we have reviewed Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015 (for Model 707–300, 707–300B, and 707–300C series airplanes); and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015 (for Model 727C, 727–100C, and 727–200F series airplanes). (We referred to Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012; and Boeing Alert Service Bulletin 727–52A0150, dated January 30, 2012; as the appropriate sources of service information for accomplishing the actions specified in the NPRM.) Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015; clarify the inspection conditions and the corrective actions for certain conditions. Certain inspections of the cam latches and latch pins were changed from detailed inspections to general visual inspections. Also, a detailed inspection of mating parts and immediately adjacent cam latches and latch pins for any cracks or any gouges in critical areas was added to certain corrective actions specified in the service information. Also, the corrective actions for latch pin extensions that are between 0.84 and 0.89 inch or between 0.91 and 0.94 inch were changed. Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015; specify replacement of any discrepant latch pin and a detailed inspection of the mating cam latch for any cracks or gouges in lieu of the repetitive detailed inspections described in Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012; and Boeing Alert Service Bulletin 727–52A0150, dated January 30, 2012. Explanation of Certain Changes to This AD In light of the issuance of the revised service information discussed previously, we have revised paragraphs PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 87413 (c), (g), and (h) of this AD to refer to Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015. We have also added new paragraph (l) of this AD to give credit for doing actions before the effective date of this AD using Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012; and Boeing Alert Service Bulletin 727–52A0150, dated January 30, 2012. In addition, we have removed the Optional Terminating Action, which was paragraph (m) in the proposed AD, and moved that information into paragraph (g)(2) of this AD to align with the revised service information. We have redesignated subsequent paragraphs accordingly. In addition, since certain inspections and conditions were revised in Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727– 52A0150, Revision 1, dated November 5, 2015; we have revised the description of the actions required by this AD to correspond with the terminology used in Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015. As a result, certain paragraphs in the proposed AD have been rearranged, and the corresponding paragraph identifiers have been redesignated in this AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Action in the NPRM paragraph paragraph paragraph paragraph paragraph paragraph paragraph paragraph (g) ............ (h) ............ (i) ............. (j) ............. (k) ............ (l) ............. (m) ........... (n) ............ Corresponding requirement in this AD paragraph paragraph paragraph paragraph paragraph paragraph paragraph paragraph (g)(1). (g)(2). (h). (h). (k). (i). (g)(2). (j). We have also revised the Costs of Compliance section in this final rule to reflect the number of work-hours specified in Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015. We have also included the costs for the repetitive inspections required before the MCD rigging check as well as replacement of the alloy cross bolts; these costs were inadvertently omitted from the NPRM. In addition, we have included the costs for the concurrent actions in Boeing E:\FR\FM\05DER1.SGM 05DER1 87414 Federal Register / Vol. 81, No. 233 / Monday, December 5, 2016 / Rules and Regulations 707/720 Service Bulletin 3477, Revision 2, dated April 15, 1993; and Boeing Service Bulletin 727–52–0142, Revision 2, dated April 15, 1993. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. FedEx Express had no objection to the NPRM. sradovich on DSK3GMQ082PROD with RULES Request for Clarification of Requirements Boeing stated that it was difficult to align the requirements proposed in paragraphs (g), (h), (i), (j) and (l) of the proposed AD with the actions described in Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012; and Boeing Alert Service Bulletin 727– 52A0150, dated January 30, 2012. Boeing commented that it is not clear which requirements in the proposed AD go with which section of table 1 and table 2 in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 727– 52A0150, dated January 30, 2012. Boeing expressed concern that the proposed AD does not include all of the items in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 727– 52A0150, dated January 30, 2012. Boeing suggested that the proposed AD be rewritten so operators are not confused with unclear compliance requirements, which might cause situations of non-compliance. Boeing also requested that paragraphs (h)(1), (h)(2), (h)(3)(i), and (h)(3)(ii) of the proposed AD be rewritten to improve clarity because words were omitted that might lead to confusion or misinterpretation of the requirements in the proposed AD. We agree that the description of the parts to be inspected and the required tasks should be consistent throughout this final rule and should match what is described in the Boeing service information. With the exception of paragraph (l)(2) of this AD, we are requiring only actions that are described in Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015. We have revised paragraphs (g), (h), (i), and (j) of this AD accordingly. For clarity we have moved the ‘‘Concurrent Actions’’ paragraph of the proposed AD (paragraph (l) of the proposed AD) before the ‘‘Exceptions to VerDate Sep<11>2014 15:57 Dec 02, 2016 Jkt 241001 Service Information Specifications’’ paragraph (paragraph (k) of the proposed AD). In this AD, the ‘‘Concurrent Actions’’ paragraph is redesignated as paragraph (i) of this AD. Request To Revise Intervals for Repetitive Inspections The United States Air Force Joint STARS (Joint STARS) program stated that its concern is that the NPRM addresses only airplanes that are frequently used to haul cargo. For operators that do not haul cargo and typically only open the MCD for Ccheck inspections, the general visual inspections required every 330 flight cycles or 150 days is excessive. This commenter stated that these repetitive inspections do not fit into the current Joint STARS maintenance program and would result in airplane downtime and additional cost. This commenter noted that detailed inspections every 3,000 flight cycles or 24 months, and high frequency eddy current (HFEC) inspections every 6,000 flight cycles or 48 months, would fit into its current maintenance schedule and not cause a significant impact. We agree that the required intervals for repetitive inspections may not be appropriate for some operators because they infrequently use the cargo door. However, we disagree with revising the intervals for the repetitive inspections required by this AD. We need to evaluate the requests for different inspection intervals on a case-by-case basis, based on the operator and its use of the MCD. Operators may request a change in the intervals for the repetitive inspections by following the procedures in paragraph (m) of this AD and requesting approval of an alternative method of compliance. We also note that the FAA has limited oversight of public aircraft operations (PAO). The government entity conducting the PAO is responsible for oversight of the operations, including aircraft airworthiness. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 727–52A0150, Revision 1, dated November 5, 2015. This service information describes procedures for doing a general visual inspection for broken or missing cam latches, latch pins, and latch pin cross bolts; torqueing the cross bolts in the latch pins; measuring the extension of the latch pins; replacing all alloy steel cross bolts through the latch pins with CRES cross bolts; doing a general visual inspection of all cam latches for lip deformation; doing a HFEC or magnetic particle inspection of cam latch 1 and cam latch 2 for cracks and replacing all cracked or broken parts; checking the rig of the MCD and re-rigging as applicable; and doing related investigative and corrective actions. This service information also describes procedures for doing repetitive inspections for certain conditions specified in the service information, which terminate after the MCD rigging is done as specified in this service information. This service information also describes procedures for doing MCD post-rigging inspections and corrective actions. These service bulletins are distinct because they apply to different airplane models. We also reviewed Boeing 707/720 Service Bulletin 3477, Revision 2, dated April 15, 1993; and Boeing Service Bulletin 727–52–0142, Revision 2, dated April 15, 1993. This service information describes procedures for doing general a general visual inspection of the hinge fittings and the cam latches on the MCD, and related investigative and corrective actions. These service bulletins are distinct because they apply to different airplane models. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 18 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\05DER1.SGM 05DER1 Federal Register / Vol. 81, No. 233 / Monday, December 5, 2016 / Rules and Regulations 87415 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspection/torque/measurement ...........

We estimate the following costs to do any necessary related investigative actions and certain replacements that will be required based on the results of the inspections. We have no way of determining the number of aircraft that might need these actions: ON-CONDITION COSTS Action Labor cost Related investigative actions ..................................... Replacement of broken/missing parts ....................... Concurrent replacement 1 .......................................... Up to 3 work-hours × $85 per hour = $255 ............. 1 work-hour × $85 per hour = $85 per latch/pin ..... 26 work-hours × $85 = $2,210 ................................ 1 The $0 $0 $15,324 Up to $255. $85 per latch/pin. $17,534. concurrent replacement of parts is required by AD 91–22–04, Amendment 39–8064 (56 FR 55223, October 25, 1991). 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 sradovich on DSK3GMQ082PROD with RULES Cost per product Parts cost 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: VerDate Sep<11>2014 15:57 Dec 02, 2016 Jkt 241001 (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), (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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model FALCON 7X airplanes. The NPRM published in the Federal Register on April 13, 2016 (81 FR 21770) (‘‘the NPRM’’). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 87417 Directive 2015–0216, dated October 28, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X airplanes. The MCAI states: Several rear fuselage tanks of the Falcon 7X were assembled on the production line with a lateral panel, which had been excessively chemically-milled in some areas. Investigation results determined that the remaining thickness is insufficient to meet the certification requirements. Dassault Aviation identified the individual aeroplanes that are potentially affected by this production deficiency. Due to this reduced thickness, the risk of damaging and puncturing a fuel tank wall panel as a result of a high energy lightning strike is increased. This condition, if not detected and corrected, could lead to loss of electrical power and/or other essential functions, possibly resulting in reduced control of the aeroplane or ignition of a fuel tank. To address this potential unsafe condition, Dassault Aviation published Service Bulletin (SB) 7X–245 to provide inspection and repair instructions. For the reasons described above, this [EASA] AD requires a one-time inspection of the fuel tank wall panels and, depending on findings, accomplishment of a repair. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 5466. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Dassault Service Bulletin 7X–245, dated June 8, 2015. The service information describes procedures for measuring fuel tank panel thickness, and repair if necessary. E:\FR\FM\05DER1.SGM 05DER1

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to certain The Boeing Company 
Model 707-300, 707-300B, and 707-300C series airplanes; and certain 
Model 727C, 727-100C, and 727-200F series airplanes. The NPRM published 
in the Federal Register on March 28, 2013 (78 FR 18922) (``the NPRM''). 
The NPRM was prompted by a report indicating that a cam latch on the 
MCD broke during flight. The NPRM proposed to require performing 
repetitive inspections of the MCD cam latches; replacing cam latches, 
certain bolts, and door hinge fittings; performing related 
investigative and corrective actions, if necessary; and rigging the 
MCD. We are issuing this AD to detect and correct discrepancies of the 
cam latches, latch pins, and latch pin cross bolts, which could reduce 
the structural integrity of the MCD, and result in potential loss of 
the cargo door and rapid decompression of the airplane.

Actions Since the NPRM Was Issued

    Since we issued the NPRM, we have reviewed Boeing 707 Alert Service 
Bulletin A3536, Revision 1, dated September 16, 2015 (for Model 707-
300, 707-300B, and 707-300C series airplanes); and Boeing Alert Service 
Bulletin 727-52A0150, Revision 1, dated November 5, 2015 (for Model 
727C, 727-100C, and 727-200F series airplanes). (We referred to Boeing 
707 Alert Service Bulletin A3536, dated February 6, 2012; and Boeing 
Alert Service Bulletin 727-52A0150, dated January 30, 2012; as the 
appropriate sources of service information for accomplishing the 
actions specified in the NPRM.)
    Boeing 707 Alert Service Bulletin A3536, Revision 1, dated 
September 16, 2015; and Boeing Alert Service Bulletin 727-52A0150, 
Revision 1, dated November 5, 2015; clarify the inspection conditions 
and the corrective actions for certain conditions. Certain inspections 
of the cam latches and latch pins were changed from detailed 
inspections to general visual inspections. Also, a detailed inspection 
of mating parts and immediately adjacent cam latches and latch pins for 
any cracks or any gouges in critical areas was added to certain 
corrective actions specified in the service information.
    Also, the corrective actions for latch pin extensions that are 
between 0.84 and 0.89 inch or between 0.91 and 0.94 inch were changed. 
Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 
16, 2015; and Boeing Alert Service Bulletin 727-52A0150, Revision 1, 
dated November 5, 2015; specify replacement of any discrepant latch pin 
and a detailed inspection of the mating cam latch for any cracks or 
gouges in lieu of the repetitive detailed inspections described in 
Boeing 707 Alert Service Bulletin A3536, dated February 6, 2012; and 
Boeing Alert Service Bulletin 727-52A0150, dated January 30, 2012.

Explanation of Certain Changes to This AD

    In light of the issuance of the revised service information 
discussed previously, we have revised paragraphs (c), (g), and (h) of 
this AD to refer to Boeing 707 Alert Service Bulletin A3536, Revision 
1, dated September 16, 2015; and Boeing Alert Service Bulletin 727-
52A0150, Revision 1, dated November 5, 2015. We have also added new 
paragraph (l) of this AD to give credit for doing actions before the 
effective date of this AD using Boeing 707 Alert Service Bulletin 
A3536, dated February 6, 2012; and Boeing Alert Service Bulletin 727-
52A0150, dated January 30, 2012. In addition, we have removed the 
Optional Terminating Action, which was paragraph (m) in the proposed 
AD, and moved that information into paragraph (g)(2) of this AD to 
align with the revised service information. We have redesignated 
subsequent paragraphs accordingly.
    In addition, since certain inspections and conditions were revised 
in Boeing 707 Alert Service Bulletin A3536, Revision 1, dated September 
16, 2015; and Boeing Alert Service Bulletin 727-52A0150, Revision 1, 
dated November 5, 2015; we have revised the description of the actions 
required by this AD to correspond with the terminology used in Boeing 
707 Alert Service Bulletin A3536, Revision 1, dated September 16, 2015; 
and Boeing Alert Service Bulletin 727-52A0150, Revision 1, dated 
November 5, 2015. As a result, certain paragraphs in the proposed AD 
have been rearranged, and the corresponding paragraph identifiers have 
been redesignated in this AD, as listed in the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                            Corresponding requirement in

paragraph (l).............................  paragraph (i).
paragraph (m).............................  paragraph (g)(2).
paragraph (n).............................  paragraph (j).
------------------------------------------------------------------------

    We have also revised the Costs of Compliance section in this final 
rule to reflect the number of work-hours specified in Boeing 707 Alert 
Service Bulletin A3536, Revision 1, dated September 16, 2015; and 
Boeing Alert Service Bulletin 727-52A0150, Revision 1, dated November 
5, 2015. We have also included the costs for the repetitive inspections 
required before the MCD rigging check as well as replacement of the 
alloy cross bolts; these costs were inadvertently omitted from the 
NPRM. In addition, we have included the costs for the concurrent 
actions in Boeing

[[Page 87414]]

707/720 Service Bulletin 3477, Revision 2, dated April 15, 1993; and 
Boeing Service Bulletin 727-52-0142, Revision 2, dated April 15, 1993.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.
    FedEx Express had no objection to the NPRM.

Request for Clarification of Requirements

    Boeing stated that it was difficult to align the requirements 
proposed in paragraphs (g), (h), (i), (j) and (l) of the proposed AD 
with the actions described in Boeing 707 Alert Service Bulletin A3536, 
dated February 6, 2012; and Boeing Alert Service Bulletin 727-52A0150, 
dated January 30, 2012. Boeing commented that it is not clear which 
requirements in the proposed AD go with which section of table 1 and 
table 2 in paragraph 1.E., ``Compliance,'' of Boeing Alert Service 
Bulletin 727-52A0150, dated January 30, 2012. Boeing expressed concern 
that the proposed AD does not include all of the items in paragraph 
1.E., ``Compliance,'' of Boeing Alert Service Bulletin 727-52A0150, 
dated January 30, 2012. Boeing suggested that the proposed AD be 
rewritten so operators are not confused with unclear compliance 
requirements, which might cause situations of non-compliance.
    Boeing also requested that paragraphs (h)(1), (h)(2), (h)(3)(i), 
and (h)(3)(ii) of the proposed AD be rewritten to improve clarity 
because words were omitted that might lead to confusion or 
misinterpretation of the requirements in the proposed AD.
    We agree that the description of the parts to be inspected and the 
required tasks should be consistent throughout this final rule and 
should match what is described in the Boeing service information. With 
the exception of paragraph (l)(2) of this AD, we are requiring only 
actions that are described in Boeing 707 Alert Service Bulletin A3536, 
Revision 1, dated September 16, 2015; and Boeing Alert Service Bulletin 
727-52A0150, Revision 1, dated November 5, 2015. We have revised 
paragraphs (g), (h), (i), and (j) of this AD accordingly.
    For clarity we have moved the ``Concurrent Actions'' paragraph of 
the proposed AD (paragraph (l) of the proposed AD) before the 
``Exceptions to Service Information Specifications'' paragraph 
(paragraph (k) of the proposed AD). In this AD, the ``Concurrent 
Actions'' paragraph is redesignated as paragraph (i) of this AD.

Request To Revise Intervals for Repetitive Inspections

    The United States Air Force Joint STARS (Joint STARS) program 
stated that its concern is that the NPRM addresses only airplanes that 
are frequently used to haul cargo. For operators that do not haul cargo 
and typically only open the MCD for C-check inspections, the general 
visual inspections required every 330 flight cycles or 150 days is 
excessive. This commenter stated that these repetitive inspections do 
not fit into the current Joint STARS maintenance program and would 
result in airplane downtime and additional cost. This commenter noted 
that detailed inspections every 3,000 flight cycles or 24 months, and 
high frequency eddy current (HFEC) inspections every 6,000 flight 
cycles or 48 months, would fit into its current maintenance schedule 
and not cause a significant impact.
    We agree that the required intervals for repetitive inspections may 
not be appropriate for some operators because they infrequently use the 
cargo door. However, we disagree with revising the intervals for the 
repetitive inspections required by this AD. We need to evaluate the 
requests for different inspection intervals on a case-by-case basis, 
based on the operator and its use of the MCD. Operators may request a 
change in the intervals for the repetitive inspections by following the 
procedures in paragraph (m) of this AD and requesting approval of an 
alternative method of compliance.
    We also note that the FAA has limited oversight of public aircraft 
operations (PAO). The government entity conducting the PAO is 
responsible for oversight of the operations, including aircraft 
airworthiness.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing 707 Alert Service Bulletin A3536, Revision 1, 
dated September 16, 2015; and Boeing Alert Service Bulletin 727-
52A0150, Revision 1, dated November 5, 2015. This service information 
describes procedures for doing a general visual inspection for broken 
or missing cam latches, latch pins, and latch pin cross bolts; 
torqueing the cross bolts in the latch pins; measuring the extension of 
the latch pins; replacing all alloy steel cross bolts through the latch 
pins with CRES cross bolts; doing a general visual inspection of all 
cam latches for lip deformation; doing a HFEC or magnetic particle 
inspection of cam latch 1 and cam latch 2 for cracks and replacing all 
cracked or broken parts; checking the rig of the MCD and re-rigging as 
applicable; and doing related investigative and corrective actions. 
This service information also describes procedures for doing repetitive 
inspections for certain conditions specified in the service 
information, which terminate after the MCD rigging is done as specified 
in this service information. This service information also describes 
procedures for doing MCD post-rigging inspections and corrective 
actions. These service bulletins are distinct because they apply to 
different airplane models.
    We also reviewed Boeing 707/720 Service Bulletin 3477, Revision 2, 
dated April 15, 1993; and Boeing Service Bulletin 727-52-0142, Revision 
2, dated April 15, 1993. This service information describes procedures 
for doing general a general visual inspection of the hinge fittings and 
the cam latches on the MCD, and related investigative and corrective 
actions. These service bulletins are distinct because they apply to 
different airplane models.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

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),
    (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.
