PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 28893 Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2018– 0242, dated October 8, 2018 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During accomplishment of maintenance on an M28 05 military version airplane, torn pieces of thermo-shrinkable tubes were found in the header section of the main fuel tank. These tubes are installed on electrical harnesses located in the fuel tanks and serve as marking and protection devices against mechanical damage during manufacturing and servicing. Pieces of these tubes may travel with the fuel flow and may block the jet pump or reduce its performance, particularly in the centre-wing fuel tank, in which the jet pump is the only way of further transfer of fuel to the engine. Subsequent investigation determined that degradation of the tube material was caused by a manufacturing deficiency, leading to insufficient material resistance against mechanical damage when a tube is located in a fuel. This condition, if not detected and corrected, could lead to reduced fuel supply to the engines, inability to use all the fuel in fuel tanks and reduced available engine power, resulting in reduced aeroplane performance. To address this potentially unsafe condition, PZL identified the batch of aeroplanes that are potentially equipped with thermo-shrinkable tubes having this manufacturing defect, and issued the [service bulletin] SB providing inspection and replacement instructions. For the reasons described above, this [EASA] AD requires a one-time inspection of the electrical harnesses located in the fuel tanks and, depending on findings, replacement of the affected harness. Polskie Zaklady Lotnicze Sp. z o.o. informed us the potential for damage to the thermo-shrinkable tubes does not progress with time. Therefore, we determined repetitive inspections are not required. You may examine the MCAI on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0473. Related Service Information Under 1 CFR Part 51 Polskie Zaklady Lotnicze Sp. z o.o. has issued Service Bulletin No. E/ 12.141/2018, dated May 15, 2018. The service information contains procedures for inspecting the thermo-shrinkable tubes on the electrical harnesses in the center and outer wing fuel tanks for damage and replacing any electrical harness with damaged thermoshrinkable tubes. This service information is reasonably available E:\FR\FM\14MYP1.SGM 14MYP1 28894 Federal Register / Vol. 85, No. 94 / Thursday, May 14, 2020 / Proposed Rules 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 and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is proposing this AD because it evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance The FAA estimates that this proposed AD would affect 15 products of U.S. registry. The FAA also estimates that it would take about 3 work-hours per product to comply with the basic inspection requirement of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, the FAA estimates the cost of the proposed AD on U.S. operators to be $3,825, or $255 per product. In addition, the FAA estimates that any necessary follow-on replacement action would take about 60 work-hours and require parts costing $5,000, for a cost of $10,100 per electrical harness. The FAA has no way of determining the number of products that may need these actions. jbell on DSKJLSW7X2PROD 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 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. VerDate Sep<11>2014 16:27 May 13, 2020 Jkt 250001 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: (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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

This proposed AD would require tap inspecting the abrasion strip within 10 hours time-in-service (TIS) and thereafter before the first flight of each day until the abrasion strip has accumulated 700 hours TIS since installation. This proposed AD is prompted by reports that leading edge abrasion strips manufactured by HTC are departing the MR blades during flight. An investigation determined that the abrasion strips were manufactured from electroformed nickel, have a chord length of 1.25 inch, and are delaminating from the MR blade before departing from the helicopter. HTC has determined that a repetitive tap inspection of the abrasion strips should be performed on all blades with abrasion strips that have less than 700 hours TIS to detect any voids, including blistering, bubbling, or lifting of the abrasion strip. Identical looking electroformed nickel abrasion strips with a chord length of 1.25 inch manufactured by other repair stations have not departed in flight and therefore are not the subject of this proposed AD. If the manufacturer of the installed abrasion strip is unknown, this proposed AD would apply to the strip. FOR FURTHER INFORMATION CONTACT: Airworthiness Directives; MD Helicopters Inc.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2018-0242, dated October 8, 2018 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    During accomplishment of maintenance on an M28 05 military 
version airplane, torn pieces of thermo-shrinkable tubes were found 
in the header section of the main fuel tank. These tubes are 
installed on electrical harnesses located in the fuel tanks and 
serve as marking and protection devices against mechanical damage 
during manufacturing and servicing. Pieces of these tubes may travel 
with the fuel flow and may block the jet pump or reduce its 
performance, particularly in the centre-wing fuel tank, in which the 
jet pump is the only way of further transfer of fuel to the engine. 
Subsequent investigation determined that degradation of the tube 
material was caused by a manufacturing deficiency, leading to 
insufficient material resistance against mechanical damage when a 
tube is located in a fuel.
    This condition, if not detected and corrected, could lead to 
reduced fuel supply to the engines, inability to use all the fuel in 
fuel tanks and reduced available engine power, resulting in reduced 
aeroplane performance.
    To address this potentially unsafe condition, PZL identified the 
batch of aeroplanes that are potentially equipped with thermo-
shrinkable tubes having this manufacturing defect, and issued the 
[service bulletin] SB providing inspection and replacement 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the electrical harnesses located in the fuel 
tanks and, depending on findings, replacement of the affected 
harness.

    Polskie Zaklady Lotnicze Sp. z o.o. informed us the potential for 
damage to the thermo-shrinkable tubes does not progress with time. 
Therefore, we determined repetitive inspections are not required. You 
may examine the MCAI on the internet at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2020-0473.

Related Service Information Under 1 CFR Part 51

    Polskie Zaklady Lotnicze Sp. z o.o. has issued Service Bulletin No. 
E/12.141/2018, dated May 15, 2018. The service information contains 
procedures for inspecting the thermo-shrinkable tubes on the electrical 
harnesses in the center and outer wing fuel tanks for damage and 
replacing any electrical harness with damaged thermo-shrinkable tubes.

course of business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with this State of Design Authority, 
it has notified the FAA of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is proposing this AD 
because it evaluated all information and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 15 products of 
U.S. registry. The FAA also estimates that it would take about 3 work-
hours per product to comply with the basic inspection requirement of 
this proposed AD. The average labor rate is $85 per work-hour.
    Based on these figures, the FAA estimates the cost of the proposed 
AD on U.S. operators to be $3,825, or $255 per product.
    In addition, the FAA estimates that any necessary follow-on 
replacement action would take about 60 work-hours and require parts 
costing $5,000, for a cost of $10,100 per electrical harness. The FAA 
has no way of determining the number of products that may need these 
actions.

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

    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:
    (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.

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):

Polskie Zaklady Lotnicze Sp. z o.o.: Docket No. FAA-2020-0473; 
Product Identifier 2018-CE-058-AD.

(a) Comments Due Date

    The FAA must receive comments by June 29, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Polskie Zaklady Lotnicze Sp. z o.o. Model PZL 
M28 05 airplanes, serial numbers AJE00301 through AJE00343, and 
AJE00345 through AJE00347, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 28: Fuel Tank.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as defective 
thermo-shrinkable tubes installed on the electrical harnesses 
located in the fuel tanks. The FAA is issuing this AD to prevent 
broken pieces of the thermo-shrinkable tubes from blocking the jet 
pump, reducing fuel supply to the engines, and resulting in the 
inability to use all the fuel in the fuel tanks. This condition 
could lead to reduced engine power and airplane performance.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) and (2) of this AD:
    (1) Within the next 200 hours time-in-service (TIS) after the 
effective date of this AD or within the next 8 months after the 
effective date of this AD, whichever occurs first:
    (i) Inspect each electrical wire harness in the center wing and 
the left-hand and right-hand outer wing fuel tanks for cracking, 
tears, and seizing of the thermo-shrinkable tubes in accordance with 
paragraphs II.1 through 2 a) of the Procedure for Bulletin Execution 
section in Polskie Zaklady Lotnicze Sp. z o.o. Service Bulletin No. 
E/12.141/2018, dated May 15, 2018.
    (ii) If there is a tear or any cracking in or any seizing of an 
electrical wire harness thermo-shrinkable tube, before further 
flight, replace the harness in accordance with section II. a) 
Replacement of harness KL8 (KP), II. b) Replacement of Harness KL9 
(KP9), or II. c) Replacement of harness KL10 (KP10), as applicable, 
of the Procedure for Bulletin Execution in Polskie Zaklady Lotnicze 
Sp. z o.o. Service Bulletin No. E/12.141/2018, dated May 15, 2018.
    (2) As of the effective date of this AD, do not install any 
electrical wire harness part number 28.14.7205.073.000, 
28.14.7205.074.000, 28.14.7205.075.000, 28.14.7205.076.000, 
28.14.7205.077.000, or 28.14.7205.078.000, that has more than zero 
hours TIS on any airplane, unless it has passed the inspection 
required by paragraph (f)(1)(i) of this AD.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Small Airplane Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Send information to ATTN: Doug
