SUPPLEMENTARY INFORMATION:
khammond on DSKJM1Z7X2PROD with RULES
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 serial-numbered Polskie
Zaklady Lotnicze Sp. z o.o. Model PZL
M28 05 airplanes. The NPRM published
in the Federal Register on May 14, 2020
(85 FR 28893). The NPRM proposed to
correct an unsafe condition for the
specified products and was based on
MCAI originated by the European Union
Aviation Safety Agency (EASA), which
is the Technical Agent for the Member
States of the European Union. EASA
issued AD No. 2018–0242, dated
October 8, 2018 (referred to after this as
‘‘the MCAI’’), which 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.
VerDate Sep<11>2014
15:54 Nov 02, 2020
Jkt 253001
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 the FAA the potential for
damage to the thermo-shrinkable tubes
does not progress with time. Therefore,
the FAA 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.
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.
Support for the NPRM
An individual commenter supported
the NPRM.
Request To Change the Cost of
Compliance
Another individual commenter
requested the FAA increase the
estimated number of labor hours in the
cost of compliance. The commenter
stated the number of hours should be
increased from 3 to at least 44 to 48,
based on the time and personnel needed
to open the center wing panels, properly
shore the engines, open the tank covers,
perform the inspection, and complete
the close up. The commenter further
stated that this would not include costs
for any de-fueling, de-puddling, refueling, or leak checks that may need to
be done.
The FAA disagrees. The cost analysis
in AD rulemaking actions typically
includes only the costs associated with
complying with the AD. In the NPRM,
the FAA estimated 3 work hours to
perform the inspection and 60 work
hours, if necessary, to replace the
harness, based on information from the
design approval holder. The compliance
time for this AD allows the operator do
this inspection at the same time as other
maintenance when the airplane has
been prepared for other tasks. No
changes were made to the proposed AD
based on this comment.

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.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Polskie Zaklady
Lotnicze Sp. z o.o. 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
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 will
affect 15 products of U.S. registry. The
FAA also estimates that it will take
about 3 work-hours per product to
comply with the inspection requirement
of this AD. The average labor rate is $85
per work-hour.
Based on these figures, the FAA
estimates the cost of the 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 will 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 airplanes 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
E:\FR\FM\03NOR1.SGM

Federal Register / Vol. 85, No. 213 / Tuesday, November 3, 2020 / Rules and Regulations
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 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.

Member States of the European Union. EASA issued AD No. 2018-0242,
dated October 8, 2018 (referred to after this as ``the MCAI''), which
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 the FAA the potential
for damage to the thermo-shrinkable tubes does not progress with time.
Therefore, the FAA determined repetitive inspections are not required.

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.
Support for the NPRM
An individual commenter supported the NPRM.
Request To Change the Cost of Compliance
Another individual commenter requested the FAA increase the
estimated number of labor hours in the cost of compliance. The
commenter stated the number of hours should be increased from 3 to at
least 44 to 48, based on the time and personnel needed to open the
center wing panels, properly shore the engines, open the tank covers,
perform the inspection, and complete the close up. The commenter
further stated that this would not include costs for any de-fueling,
de-puddling, re-fueling, or leak checks that may need to be done.
The FAA disagrees. The cost analysis in AD rulemaking actions
typically includes only the costs associated with complying with the
AD. In the NPRM, the FAA estimated 3 work hours to perform the
inspection and 60 work hours, if necessary, to replace the harness,
based on information from the design approval holder. The compliance
time for this AD allows the operator do this inspection at the same
time as other maintenance when the airplane has been prepared for other
tasks. No changes were made to the proposed AD based on this comment.
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.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Polskie Zaklady Lotnicze Sp. z o.o. 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. 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 will affect 15 products of U.S.
registry. The FAA also estimates that it will take about 3 work-hours
per product to comply with the inspection requirement of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the cost of the 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 will 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 airplanes 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
[[Page 69498]]
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 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.

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):
2020-22-12 Polskie Zaklady Lotnicze Sp. z o.o: Amendment 39-21308;
Docket No. FAA-2020-0473; Project Identifier 2018-CE-058-AD.
(a) Effective Date
This AD is effective December 8, 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.
