The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for Bombardier Model DHC–8– 100/–200/–300 series airplanes modified by Avmax Aviation Services Inc. In lieu of the requirements of 14 CFR 25.1353(c)(1) through (c)(4) at Amendment 25–51, all rechargeable lithium batteries and battery systems on Model DHC–8–100/–200/–300 airplanes, as modified by Avmax Aviation Services Inc., must be designed and installed as follows: 1. Safe cell temperatures and pressures must be maintained during any foreseeable charging or discharging condition and during any failure of the charging or battery monitoring system not shown to be extremely remote. The rechargeable lithium battery installation must preclude explosion in the event of those failures. 2. Design of the rechargeable lithium batteries must preclude the occurrence of self-sustaining, uncontrolled increases in temperature or pressure. 3. No explosive or toxic gases emitted by any rechargeable lithium battery in normal operation, or as the result of any failure of the battery charging system, monitoring system, or battery installation which is not shown to be extremely remote, may accumulate in hazardous quantities within the airplane. 4. Installations of rechargeable lithium batteries must meet the requirements of § 25.863(a) through (d). 5. No corrosive fluids or gases that may escape from any rechargeable lithium battery may damage surrounding structure or any adjacent systems, equipment, or electrical wiring of the airplane in such a way as to cause a major or more-severe failure condition, in accordance with § 25.1309(b) and applicable regulatory guidance. 6. Each rechargeable lithium battery installation must have provisions to prevent any hazardous effect on structure or essential systems caused by the maximum amount of heat the battery can generate during a short circuit of the battery or of its individual cells. 7. Lithium battery installations must have a system to control the charging rate of the battery automatically, designed to prevent battery overheating or overcharging, and, asabaliauskas on DSK3SPTVN1PROD with RULES ■ VerDate Sep<11>2014 17:30 Jul 22, 2016 Jkt 238001 a. A battery-temperature sensing and over-temperature warning system with a means for automatically disconnecting the battery from its charging source in the event of an over-temperature condition, or, b. A battery-failure sensing and warning system with a means for automatically disconnecting the battery from its charging source in the event of battery failure. 8. Any rechargeable lithium battery installation, the function of which is required for safe operation of the airplane, must incorporate a monitoring and warning feature that will provide an indication to the appropriate flight crewmembers whenever the state-ofcharge of the batteries has fallen below levels considered acceptable for dispatch of the airplane. 9. The instructions for continued airworthiness required by § 25.1529 must contain maintenance requirements to assure that the battery is sufficiently charged at appropriate intervals specified by the battery manufacturer and the equipment manufacturer that contain the rechargeable lithium battery or rechargeable lithium battery system. This is required to ensure that rechargeable lithium batteries and rechargeable lithium battery systems will not degrade below specified ampere-hour levels sufficient to power the airplane systems for intended applications. The instructions for continued airworthiness must also contain procedures for the maintenance of batteries in spares storage to prevent the replacement of batteries with batteries that have experienced degraded charge retention ability or other damage due to prolonged storage at a low state of charge. Replacement batteries must be of the same manufacturer and part number as approved by the FAA. Precautions should be included, in the instructions for continued airworthiness maintenance instructions, to prevent mishandling of the rechargeable lithium battery and rechargeable lithium battery systems, which could result in shortcircuit, or other unintentional impact damage caused by dropping batteries or other destructive means that could result in personal injury or property damage. Note 1: The term ‘‘sufficiently charged’’ means that the battery will retain enough of a charge, expressed in ampere-hours, to ensure that the battery cells will not be damaged. A battery cell may be damaged by lowering the charge below a point where the battery experiences a reduction in the ability to charge and retain a full charge. This reduction would be greater than the PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 48321 reduction that may result from normal operational degradation. Note 2: These special conditions are not intended to replace § 25.1353(c) in the certification basis of Bombardier Model DHC–8–100/–200/–300 series airplanes. These special conditions apply only to rechargeable lithium batteries and lithium battery systems and their installations on Bombardier Model DHC–8–100/–200/–300 series airplanes, as modified by Avmax. The requirements of § 25.1353(c) remain in effect for batteries and battery installations on Bombardier Model DHC–8–100/–200/–300 series airplanes that do not use lithium batteries.

SUPPLEMENTARY INFORMATION: Discussion On January 14, 2013, we issued AD 2013–02–02, Amendment 39–17323 (78 VerDate Sep<11>2014 17:30 Jul 22, 2016 Jkt 238001 FR 5712, January 28, 2013), (‘‘AD 2013– 02–02’’) for all CFM56–3, CFM56–3B, and CFM56–3C turbofan engines modified by Supplemental Type Certificate SE00034EN, with certain HPT disks, installed. AD 2013–02–02 required removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. AD 2013–02–02 resulted from a report of a forging process error during manufacture of these HPT disks. We issued AD 2013– 02–02 to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane. Actions Since AD 2013–02–02 Was Issued Since we issued AD 2013–02–02, we received reports that certain HPT disk S/Ns GLKBAA9307, GLKBAA9335, GLKBAA9404, GLKBAA9407, and GLKBAA9409, in AD 2013–02–02 and in certain Pratt & Whitney service information are incorrect. The correct S/ Ns are: GKLBAA9307, GKLBAA9335, GKLBAA9404, GKLBAA9407, and GKLBAA9409. Related Service Information Under 1 CFR Part 51 We reviewed Pratt & Whitney Corp. Special Instruction No. 6F–12, Revision A, dated May 17, 2016. The Special Instruction describes procedures for reducing the maximum life limit for affected HPT disks. 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. FAA’s Determination We are issuing 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. AD Requirements This AD requires removal from service of affected HPT disks at certain recalculated reduced maximum life limits. FAA’s Justification and Determination of the Effective Date No domestic operators use this product. Therefore, we find that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2012–1289; Directorate Identifier 2012– NE–43–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 0 engines installed on airplanes of U.S. registry. We also estimate that it will take about 61 hours per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $0 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $0. 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 E:\FR\FM\25JYR1.SGM 25JYR1 Federal Register / Vol. 81, No. 142 / Monday, July 25, 2016 / Rules and Regulations 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 to the extent that it justifies making a regulatory distinction, 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

    On January 14, 2013, we issued AD 2013-02-02, Amendment 39-17323 
(78 FR 5712, January 28, 2013), (``AD 2013-02-02'') for all CFM56-3, 
CFM56-3B, and CFM56-3C turbofan engines modified by Supplemental Type 
Certificate SE00034EN, with certain HPT disks, installed. AD 2013-02-02 
required removal from service of certain high-pressure turbine (HPT) 
disks manufactured by Global Material Solutions of Pratt & Whitney, at 
reduced maximum life limits. AD 2013-02-02 resulted from a report of a 
forging process error during manufacture of these HPT disks. We issued 
AD 2013-02-02 to prevent uncontained release of multiple turbine 
blades, damage to the engine, and damage to the airplane.

Actions Since AD 2013-02-02 Was Issued

    Since we issued AD 2013-02-02, we received reports that certain HPT 
disk S/Ns GLKBAA9307, GLKBAA9335, GLKBAA9404, GLKBAA9407, and 
GLKBAA9409, in AD 2013-02-02 and in certain Pratt & Whitney service 
information are incorrect. The correct S/Ns are: GKLBAA9307, 
GKLBAA9335, GKLBAA9404, GKLBAA9407, and GKLBAA9409.

Related Service Information Under 1 CFR Part 51

    We reviewed Pratt & Whitney Corp. Special Instruction No. 6F-12, 
Revision A, dated May 17, 2016. The Special Instruction describes 
procedures for reducing the maximum life limit for affected HPT disks. 
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.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires removal from service of affected HPT disks at 
certain recalculated reduced maximum life limits.

FAA's Justification and Determination of the Effective Date

    No domestic operators use this product. Therefore, we find that 
notice and opportunity for prior public comment are unnecessary and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2012-1289; Directorate Identifier 2012-NE-43-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 0 engines installed on airplanes 
of U.S. registry. We also estimate that it will take about 61 hours per 
engine to comply with this AD. The average labor rate is $85 per hour. 
Required parts cost about $0 per engine. Based on these figures, we 
estimate the cost of this AD on U.S. operators to be $0.

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

[[Page 48323]]

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 to the extent 
that it justifies making a regulatory distinction, 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (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 removing airworthiness directive (AD) 
2013-02-02, Amendment 39-17323 (78 FR 5712, January 28, 2013), (``AD 
2013-02-02''), and adding the following new AD:

2016-14-10 CFM International, S.A. Turbofan Engines Modified by 
Supplemental Type Certificate SE00034EN: Amendment 39-18591; Docket 
No. FAA-2012-1289; Directorate Identifier 2012-NE-43-AD.

(a) Effective Date

    This AD is effective August 9, 2016.

(b) Affected ADs

    This AD supersedes AD 2013-02-02.

(c) Applicability

    This AD applies to CFM International, S.A. CFM56-3, CFM56-3B, 
and CFM56-3C turbofan engines, modified by Supplemental Type 
Certificate SE00034EN, with a high-pressure turbine (HPT) disk, part 
number (P/N) 880026, serial number (S/N) GKLBAA9307, GKLBAA9335, 
GKLBAA9404, GKLBAA9407, or GKLBAA9409, installed.

(d) Unsafe Condition

    This AD was prompted by reports that certain HPT disk serial 
numbers in AD 2013-02-02 and in certain Pratt & Whitney service 
information are incorrect. We are issuing this AD to prevent 
uncontained release of multiple turbine blades, damage to the 
engine, and damage to the airplane.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) For CFM56-3, CFM56-3B, and CFM56-3C turbofan engines 
operating to 20,100 lbs maximum takeoff (MTO) thrust, remove the HPT 
disk from service on or before accumulating 8,000 cycles-since-new 
(CSN).
    (2) For CFM56-3B and CFM56-3C turbofan engines operating to 
22,100 lbs MTO thrust, remove the HPT disk from service on or before 
accumulating 8,000 CSN.
    (3) For CFM56-3C turbofan engines operating to 23,500 lbs MTO 
thrust, remove the HPT disk from service on or before accumulating 
4,000 CSN.
    (4) For HPT disks that have been used in multiple models or 
thrust installations, use the formula in the ADDED DATA section of 
Pratt & Whitney Special Instruction 6F-12, Revision A, dated May 17, 
2016 to calculate the remaining life on the disk.

(f) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, FAA, may approve AMOCs 
for this AD. Use the procedures found in 14 CFR 39.19 to make your 
request. You may email your request to: ANE-AD-AMOC@faa.gov.
