We are superseding Airworthiness Directive (AD) 2012-17-13, which applied to certain The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. For certain airplanes, AD 2012-17- 13 required using redefined flight cycle counts; determining the type of material of the horizontal stabilizer, rear spar, and upper and lower chords on the inboard and outboard ends of the rear spar; repetitively inspecting for cracking of the horizontal stabilizer components; and repairing or replacing the chord, or modifying chord segments made of 7079 aluminum, if necessary. For all airplanes, AD 2012-17-13 required inspecting certain structurally significant items, and repairing discrepancies if necessary. This new AD adds a requirement to replace all chord segments made of 7079 aluminum with new, improved chord segments made of 7075 aluminum. This AD was prompted by a determination that all chord segments made of 7079 aluminum must be replaced with new, improved chord segments made of 7075 aluminum. We are issuing this AD to detect and correct stress corrosion and potential early fatigue cracking in the horizontal stabilizer, which could result in reduced structural integrity of the horizontal stabilizer.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-17-13, 
which applied to certain The Boeing Company Model 707 airplanes, and 
Model 720 and 720B series airplanes. For certain airplanes, AD 2012-17-
13 required using redefined flight cycle counts; determining the type 
of material of the horizontal stabilizer, rear spar, and upper and 
lower chords on the inboard and outboard ends of the rear spar; 
repetitively inspecting for cracking of the horizontal stabilizer 
components; and repairing or replacing the chord, or modifying chord 
segments made of 7079 aluminum, if necessary. For all airplanes, AD 
2012-17-13 required inspecting certain structurally significant items, 
and repairing discrepancies if necessary. This new AD adds a 
requirement to replace all chord segments made of 7079 aluminum with 
new, improved chord segments made of 7075 aluminum. This AD was 
prompted by a determination that all chord segments made of 7079 
aluminum must be replaced with new, improved chord segments made of 
7075 aluminum. We are issuing this AD to detect and correct stress 
corrosion and potential early fatigue cracking in the horizontal 
stabilizer, which could result in reduced structural integrity of the 
horizontal stabilizer.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-17-13, Amendment 39-17176 (77 FR 55681, 
September 11, 2012) (``AD 2012-17-13''). AD 2012-17-13 applied to 
certain The Boeing Company Model 707 airplanes, and Model 720 and 720B 
series airplanes. The NPRM published in the Federal Register on July 
30, 2015 (80 FR 45453) (``the NPRM''). The NPRM was prompted by a 
determination that all chord segments made of 7079 aluminum must be 
replaced with new, improved chord segments made of 7075 aluminum. The 
NPRM proposed to continue to require, for certain airplanes, using 
redefined flight cycle counts, determining the type of material of the 
horizontal stabilizer, rear spar, and upper and lower chords on the 
inboard and outboard ends of the rear spar; repetitively inspecting for 
cracking of the horizontal stabilizer components; and repairing or 
replacing the chord, or modifying chord segments made from 7079 
aluminum, if necessary. The NPRM also proposed to continue to require, 
for all airplanes, inspecting certain structurally significant items, 
and repairing discrepancies if necessary. The NPRM proposed to add a 
requirement to replace all chord segments made of 7079 aluminum with 
new, improved chord segments made of 7075 aluminum. We are issuing this 
AD to detect and correct stress corrosion and potential early fatigue 
cracking in the horizontal stabilizer, which could compromise the 
structural integrity of the stabilizer.

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.

Request To Clarify Certain Language in Paragraph (i) of the Proposed AD

    Boeing asked that we clarify the description of the affected 
components specified in paragraph (i) of the proposed AD, which is a 
restatement of paragraph (i) of AD 2012-17-13. Boeing stated that the 
intent of paragraph (i) of AD 2012-17-13 was to specify the inspection 
requirements for rear spar upper inboard chord segments made from 7075 
aluminum. Boeing added that the restatement in paragraph (i) of the 
proposed AD specifies, ``For all airplanes with horizontal stabilizer 
components made from 7075 . . .'' and noted that this description could 
apply to any chord segment, not just the inboard upper. Boeing asked 
that the description be clarified to specify ``any horizontal 
stabilizer with a rear spar upper inboard chord segment made from 7075 
aluminum, as determined during the inspection required by paragraph (h) 
of this AD.''
    We agree to clarify paragraph (i) of this AD. The inspection 
required by paragraph (i) of this AD must be done on upper chords made 
from 7075 aluminum that are on the inboard end of the rear spar, as 
specified in Boeing 707 Alert Service Bulletin A3515, dated December 
19, 2007; and Boeing 707 Alert Service Bulletin A3515, Revision 1, 
dated October 10, 2014; which are the appropriate sources of service 
information for accomplishing the required actions. We have revised 
paragraph (i) of this AD to clarify the inspection requirements. No 
additional action is necessary for operators that have already complied 
with paragraph (i) of this AD.

Request To Clarify Certain Language in Paragraph (j) of the Proposed AD

    Boeing also asked that we clarify the language in the restatement 
of actions specified in paragraph (j) of the proposed AD in order to 
specify that the inspections in paragraph (i) of the proposed AD can 
only be deferred for 4,000 flight cycles if the upper inboard chord is 
replaced with a new chord. Boeing stated that changing paragraph (i) of 
the proposed AD ensures that it is clear that the inspection can only 
be deferred for 4,000 flight cycles if the upper inboard chord is 
replaced.
    We agree with the commenter for the reason provided. We have 
changed paragraph (j) of this AD to specify ``For airplanes on which 
the rear spar upper inner chord is replaced with a new chord . . . :''

Request To Clarify Certain Language in Paragraph (q) of the Proposed AD

    Boeing also asked that we clarify the language in the new actions 
specified in paragraph (q) of the proposed AD. Boeing stated that 
paragraph (j) of the proposed AD states when to resume the inspections 
after the chord is replaced. Boeing added that paragraph (i) of the 
proposed AD states the type of inspection and the repetitive inspection 
interval. Therefore, Boeing stated that paragraph (q) of the proposed 
AD should point to paragraph (i) of the proposed AD.
    We agree to clarify paragraph (q) of this AD. As noted above, 
paragraph (j) of the this AD specifies inspecting the new chord within 
4,000 flight cycles after the chord replacement, as required by 
paragraph (i) of this AD, and repeating the inspections thereafter at 
the times specified in paragraph (i) of this AD. Therefore, we have 
included similar language in paragraph (q) of this AD.

Request To Clarify Service Information References

    In addition, Boeing asked that we include 707 in the title for 
``Boeing Service Bulletin 3381,'' as identified in paragraphs (k) and 
(l) of the proposed AD, to be consistent with all the other service 
information references in the NPRM.
    We agree with the commenter for the reasons provided. We have 
changed the service information references in paragraphs (k)(3)(i) and 
(l) of this AD to specify ``Boeing 707 Service Bulletin 3381.''
    Boeing also asked that we change the semi-colon (located between 
the service information references) in paragraph (k)(3)(ii) of the 
proposed AD to a comma, because it breaks up the sentence in an 
unintended way.
    We do not agree to change the semi-colon in paragraph (k)(3)(ii) of 
this AD. In ADs, we use a semi-colon to separate service information 
references, except in cases where the semi-colon between service 
information might cause confusion, e.g., a sentence that already uses 
semi-colons between text other than the service information. The semi-
colon in paragraph (k)(3)(ii) of this AD does not change the intent of 
that paragraph. We have not changed this AD in this regard.

Conclusion

    We reviewed the available data 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.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing 707 Alert Service Bulletin A3515, Revision 1, 
dated October 10, 2014. The service

[[Page 23588]]

information describes procedures for incorporating a new cycle counting 
procedure, determining the material for the horizontal stabilizer rear 
spar chord segment, inspecting for stress corrosion cracking and 
fatigue cracking, repair, and replacing all chord segments made of 7079 
aluminum with new, improved chord segments made of 7075 aluminum. 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 10 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

1 The parts for the modification could cost up to $2.28 million per airplane, depending on whether only one
  operator is ordering the parts or multiple operators. The parts cost will go down if multiple operators order
  parts at the same time.
2 The number of chords which must be replaced on each specific airplane varies.

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 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.
