SUPPLEMENTARY INFORMATION: jbell on DSKJLSW7X2PROD with RULES Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would VerDate Sep<11>2014 16:02 May 15, 2020 Jkt 250001 apply to certain The Boeing Company Model 727, 727C, 727–100, 727–100C, 727–200, and 727–200F series airplanes. The NPRM published in the Federal Register on January 17, 2020 (85 FR 2914). The NPRM was prompted by reports of nuisance stick shaker activation while the airplane accelerated to cruise speed at the top of climb. The NPRM was also prompted by an investigation of those reports that revealed that the AOA sensor vanes could not prevent the build-up of ice, causing the AOA sensor vanes to become immobilized, which resulted in nuisance stick shaker activation. The NPRM proposed to require a general visual inspection of the AOA sensors for certain AOA sensors, and replacement of affected AOA sensors. The FAA is issuing this AD to address ice buildup in the AOA sensor faceplate and vane, which may immobilize the AOA sensor vanes, and could result in inaccurate or unreliable AOA sensor data being transmitted to airplane systems and consequent loss of controllability of the airplane. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Boeing, Richard Rodriguez, and Shaun Felix indicated support for the NPRM. Request To Reduce the Compliance Time An anonymous commenter supported the intent of the NPRM, but the FAA infers that the commenter requests that the FAA reduce the proposed compliance time from 2,750 flight hours or 36 months, whichever occurs first, to 12 months. The commenter stated the time period feels too slow. The commenter also stated repairing a piece of technology from 1963 in 12 months should not be insurmountable. Richard Rodriguez also commented that the compliance time is excessive compared to the 12-month compliance time for other models. The FAA infers the commenter is requesting the compliance time be shortened to 12 months. The FAA does not agree with the request to shorten the compliance time. After considering all the available information, the FAA has determined PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 29599 that the compliance time, as proposed, represents an appropriate interval of time in which the required actions can be performed in a timely manner within the affected fleet, while still maintaining an adequate level of safety. In developing an appropriate compliance time, the FAA considered the safety implications, parts availability, and normal maintenance schedules for timely accomplishment of the inspection and applicable replacements. Furthermore, other models affected by this unsafe condition are subject to AD 2019–24–18, Amendment 39–21007 (84 FR 71778, December 30, 2019) (‘‘AD 2019–24–18’’), which requires compliance within 36 months or at the applicable time specified in the applicable service information, whichever occurs first. The compliance time in AD 2019–24–18 is consistent with the compliance time in this AD. The FAA has not changed the AD in this regard. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing 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 The FAA reviewed Boeing Alert Service Bulletin 727–34A0247, Revision 1, dated October 1, 2019, which the Director of the Federal Register approved for incorporation by reference as of February 3, 2020 (84 FR 71778, December 30, 2019). 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 The FAA estimates that this AD affects 1 airplane of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\18MYR1.SGM 18MYR1 29600 Federal Register / Vol. 85, No. 96 / Monday, May 18, 2020 / Rules and Regulations ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Parts cost Cost per product Inspection ................... Replacement .............. 1 work-hour × $85 per hour = $85 ................. Up to 3 work-hours × $85 per hour = Up to $255. $0 ............................... Up to $54,000 ............ $85 ............................. Up to $54,255 ............ 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. The FAA is 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) Will not affect intrastate aviation in Alaska, 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.

SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0271, dated October 30, 2019 (‘‘EASA AD 2019–0271’’) (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all 328 Support Services GmbH Model 328–300 airplanes. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all 328 Support Services GmbH Model 328–300 airplanes. The NPRM published in the Federal Register on February 12, 2020 (85 FR 7897). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in an EASA AD. The FAA is issuing this AD to address the potential failure of parts, which could lead to reduced control of the airplane; and to address the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. See the MCAI for additional background information. Examining the AD Docket Comments The FAA gave the public the opportunity to participate in developing this final rule.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain The Boeing Company Model 727, 727C, 727-100, 727-100C, 727-200, 
and 727-200F series airplanes. This AD was prompted by reports of 
nuisance stick shaker activation while the airplane accelerated to 
cruise speed at the top of climb. This AD was also prompted by an 
investigation of those reports that revealed that the angle of attack

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain The Boeing 
Company Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F 
series airplanes. The NPRM published in the Federal Register on January 
17, 2020 (85 FR 2914). The NPRM was prompted by reports of nuisance 
stick shaker activation while the airplane accelerated to cruise speed 
at the top of climb. The NPRM was also prompted by an investigation of 
those reports that revealed that the AOA sensor vanes could not prevent 
the build-up of ice, causing the AOA sensor vanes to become 
immobilized, which resulted in nuisance stick shaker activation. The 
NPRM proposed to require a general visual inspection of the AOA sensors 
for certain AOA sensors, and replacement of affected AOA sensors.
    The FAA is issuing this AD to address ice buildup in the AOA sensor 
faceplate and vane, which may immobilize the AOA sensor vanes, and 
could result in inaccurate or unreliable AOA sensor data being 
transmitted to airplane systems and consequent loss of controllability 
of the airplane.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment. Boeing, 
Richard Rodriguez, and Shaun Felix indicated support for the NPRM.

Request To Reduce the Compliance Time

    An anonymous commenter supported the intent of the NPRM, but the 
FAA infers that the commenter requests that the FAA reduce the proposed 
compliance time from 2,750 flight hours or 36 months, whichever occurs 
first, to 12 months. The commenter stated the time period feels too 
slow. The commenter also stated repairing a piece of technology from 
1963 in 12 months should not be insurmountable. Richard Rodriguez also 
commented that the compliance time is excessive compared to the 12-
month compliance time for other models. The FAA infers the commenter is 
requesting the compliance time be shortened to 12 months.
    The FAA does not agree with the request to shorten the compliance 
time. After considering all the available information, the FAA has 
determined that the compliance time, as proposed, represents an 
appropriate interval of time in which the required actions can be 
performed in a timely manner within the affected fleet, while still 
maintaining an adequate level of safety. In developing an appropriate 
compliance time, the FAA considered the safety implications, parts 
availability, and normal maintenance schedules for timely 
accomplishment of the inspection and applicable replacements. 
Furthermore, other models affected by this unsafe condition are subject 
to AD 2019-24-18, Amendment 39-21007 (84 FR 71778, December 30, 2019) 
(``AD 2019-24-18''), which requires compliance within 36 months or at 
the applicable time specified in the applicable service information, 
whichever occurs first. The compliance time in AD 2019-24-18 is 
consistent with the compliance time in this AD. The FAA has not changed 
the AD in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing 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

    The FAA reviewed Boeing Alert Service Bulletin 727-34A0247, 
Revision 1, dated October 1, 2019, which the Director of the Federal 
Register approved for incorporation by reference as of February 3, 2020 
(84 FR 71778, December 30, 2019). 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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2020-06-19 The Boeing Company: Amendment 39-19888; Docket No. FAA-
2019-1072; Product Identifier 2019-NM-181-AD.

(a) Effective Date

    This AD is effective June 22, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 727, 727C, 727-100, 
727-100C, 727-200, and 727-200F series airplanes, certificated in 
any category, variable numbers QB065, QD191, QD192, QD402, QD403, 
QD407, and QD410.

(d) Subject

    Air Transport Association (ATA) of America Code 34, Navigation.

(e) Unsafe Condition

    This AD was prompted by reports of nuisance stick shaker 
activation while the airplane accelerated to cruise speed at the top 
of climb. This AD was also prompted by an investigation of those 
reports that revealed that the angle of attack (AOA) (also known as 
angle of airflow) sensor vanes could not prevent the build-up of 
ice, causing the AOA sensor vanes to become immobilized, which 
resulted in nuisance stick shaker activation. The FAA is issuing 
this AD to address ice buildup in the AOA sensor faceplate and vane, 
which may immobilize the AOA sensor vanes, and could result in 
inaccurate or unreliable AOA sensor data being transmitted to 
airplane systems and consequent loss of controllability of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified in paragraph (h) of this AD: Within 36 
months after the effective date of this AD or at the applicable 
times specified in paragraph 1.E., ``Compliance,'' of Boeing Alert 
Service Bulletin 727-34A0247, Revision 1, dated October 1, 2019, 
whichever occurs first, do all applicable actions identified as 
``RC'' (required for compliance) in, and in accordance with, the 
Accomplishment Instructions of Boeing Alert Service Bulletin 727-
34A0247, Revision 1, dated October 1, 2019.

(h) Exceptions to Service Information Specifications

    Where Boeing Alert Service Bulletin 727-34A0247, Revision 1, 
dated October 1, 2019, uses the phrase ``the original issue date of 
this service bulletin,'' this AD requires using ``the effective date 
of this AD.''

(i) Credit for Previous Actions

    This paragraph provides credit for the actions specified in 
paragraph (g) of this AD, if those actions were performed before the 
effective date of this AD using Boeing Alert Service Bulletin 727-
34A0247, dated January 2, 2019.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles ACO Branch, FAA, has the authority 
to approve AMOCs for this AD, if requested using the procedures 
found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your 
request to your principal inspector or local Flight Standards 
District Office, as appropriate. If sending information directly to 
the manager of the certification office, send it to the attention of 
the person identified in paragraph (k)(1) of this AD. Information 
may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Los 
Angeles ACO Branch, FAA, to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) Except as specified by paragraph (h) of this AD: For service 
information that contains steps that are labeled as Required for 
Compliance (RC), the provisions of paragraphs (j)(4)(i) and (ii) of 
this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC

[[Page 29601]]

requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
