The FAA will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion The FAA received reports of two inflight shutdowns due to oil leaking from the connection between the LP10 tube and the fuel oil cooler. This condition, if not addressed, could result in failure of the LP10 oil tube, engine fire and damage to the airplane. Related Service Information Under 1 CFR Part 51 The FAA reviewed PW Service Bulletin (SB) PW SB PW1000–A–79– 00–0004–00B–930A–D, dated March 20, 2019, and PW SB PW1000–A–79–00– 0011–00A–930A–D, dated March 20, 2019. PW SB PW1000–A–79–00–0004– 00B–930A–D describes procedures for modification or replacement of the FOC on PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G–A model turbofan engines. PW SB PW1000–A– 79–00–0011–00A–930A–D describes procedures for modification or replacement of the FOCs on PW1519G, PW1521G, PW1521GA, PW1521G–3, PW1524G, PW1524G–3, PW1525G, and PW1525G–3 model turbofan engines. 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. Other Related Service Information The FAA reviewed PW SB PW SB PW1000–A–79–00–0005–00B–930A–D, dated January 25, 2019; PW SB PW1000–A–79–00–0012–00A–930A–D, dated January 25, 2019; PW SB PW1000–A–79–00–0007–00B–930A–D, dated March 29, 2019, and PW SB PW1000G–A–79–00–0013–00A–930A– D, dated March 29, 2019. These service bulletins describe procedures for inspections of the FOC for gaps as well as replacement of the FOC and the LP10 oil supply tube to prevent oil leaks. FAA’s Determination The FAA is 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 initial and repetitive gap inspections of the LP10 oil supply tube and the FOC and, if a gap is found, replacement of these parts. This proposed AD would further require removal and replacement of these parts at the next engine shop visit. Costs of Compliance The FAA estimates that this proposed AD affects 18 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Perform gap inspection ................................... Replace FOC .................................................. Replace LP 10 line ......................................... 2 work-hours × $85 per hour = $170 ............. 5 work-hours × $85 per hour = $425 ............. 2.5 work-hours × $85 per hour = $212.50 ..... khammond on DSKBBV9HB2PROD with PROPOSALS 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 VerDate Sep<11>2014 16:20 Sep 09, 2019 Jkt 247001 Parts cost 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 $0 69,000 1,125 Cost per product $170 69,425 1,337.50 Cost on U.S. operators $3,060 1,249,650 24,075 applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. Regulatory Findings The FAA 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: E:\FR\FM\10SEP1.SGM 10SEP1 Federal Register / Vol. 84, No. 175 / Tuesday, September 10, 2019 / Proposed Rules (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.

25, 2019; PW SB PW1000-A-79-00-0007-00B-930A-D, dated March 29, 2019, 
and PW SB PW1000G-A-79-00-0013-00A-930A-D, dated March 29, 2019. These 
service bulletins describe procedures for inspections of the FOC for 
gaps as well as replacement of the FOC and the LP10 oil supply tube to 
prevent oil leaks.

FAA's Determination

    The FAA is 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 initial and repetitive gap 
inspections of the LP10 oil supply tube and the FOC and, if a gap is 
found, replacement of these parts. This proposed AD would further 
require removal and replacement of these parts at the next engine shop 
visit.

Costs of Compliance

    The FAA estimates that this proposed AD affects 18 engines 
installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with 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.
    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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    The FAA 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:

[[Page 47447]]

    (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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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):

Pratt & Whitney: Docket No. FAA-2019-0596; Product Identifier 2019-
NE-22-AD.

(a) Comments Due Date

    The FAA must receive comments by October 25, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Pratt & Whitney (PW) PW1519G, PW1521G, 
PW1521GA, PW1524G, PW1525G, PW1521G-3, PW1524G-3, PW1525G-3, 
PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A model turbofan 
engines.

(d) Subject

    Joint Aircraft System Component (JASC) Code 7261, Turbine Engine 
Oil System.

(e) Unsafe Condition

    This AD was prompted by reports of two in-flight shutdowns due 
to oil leaking from the connection between the LP10 oil supply tube 
and the fuel oil cooler (FOC). The FAA is issuing this AD to prevent 
failure of the LP10 oil supply tube, engine fire and damage to the 
airplane. The unsafe condition, if not addressed, could result in 
engine fire and damage to the airplane.

(f) Compliance

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

(g) Required Actions

    (1) Within 300 engine cycles from the effective date of this AD, 
perform an initial gap inspection with a 0.001 inch feeler gauge 
between the LP10 oil supply tube, part number (P/N) 5312624-01, and 
the FOC, P/N 5306769.
    (i) If any gap is found, remove the LP10 oil supply tube and the 
FOC and replace with parts eligible for installation prior to 
further flight.
    (ii) If no gap is found, repeat this inspection every 850 engine 
cycles since the previous inspection.
    (2) At the next shop visit after the effective date of this AD, 
remove the LP10 oil supply tube, P/N 5312624-01, and the FOC, P/N 
5306769, and replace with parts eligible for installation.

(h) Terminating Action

    Removal of the affected LP10 oil supply tube and the FOC per the 
requirements of paragraphs (g)(1)(i) or (g)(2) of this AD 
constitutes terminating action for the inspections required by 
paragraph (g)(1) of this AD.

(i) Definition

    (1) For the purpose of this AD, an ``engine shop visit'' is the 
induction of an engine into the shop for maintenance involving the 
separation of pairs of major mating engine case flanges, except 
separation of engine flanges solely for the purposes of 
transportation of the engine without subsequent maintenance does not 
constitute an engine shop visit.
    (2) For the purpose of this AD, an LP10 tube eligible for 
installation is any LP10 tube with a P/N other than P/N 5312624-01.
    (3) For the purpose of this AD, a FOC eligible for installation 
is one with a P/N other than P/N 5306769 or an FOC modified per PW 
SB PW1000G-A-79-00-0004-00B-930A-D or PW SB PW1000G-A-79-00-0011-
00A-930A-D, both dated March 20, 2019.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO 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. You may email your 
request to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager
