ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directives (AD) 2000–23– 

26, AD 2018–14–11, and AD 2019–13– 

04, which applied to ATR–GIE Avions 

de Transport Re ́gional Model ATR72 

airplanes. AD 2019–13–04 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

maintenance instructions and 

airworthiness limitations. This AD 

requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations; as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

incorporated by reference. This AD was 

prompted by a determination that new 

or more restrictive airworthiness 

limitations are necessary. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 31, 

2021. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0173, dated August 5, 2020 (EASA 

AD 2020–0173) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all ATR–GIE 

Avions de Transport Re ́gional Model 

ATR72 airplanes. 

Airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued after December 12, 2019 must 

comply with the airworthiness 

limitations specified as part of the 

approved type design and referenced on 

the type certificate data sheet; this AD 

therefore does not include those 

airplanes in the applicability. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2019–13–04, 

Amendment 39–19677 (84 FR 35028, 

July 22, 2019) (AD 2019–13–04). AD 

2019–13–04 applied to certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR72 airplanes. The NPRM published 

in the Federal Register on November 2, 

2020 (85 FR 69272). 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 

fatigue cracking and damage in 

principal structural elements, which 

could result in reduced structural 

integrity of the airplane. See the MCAI 

for additional background information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Clarification of Affected Airplanes 

The applicability of the proposed AD 

identified the affected airplanes as 

Model ATR72 airplanes. The FAA has 

revised the applicability of this AD to 

identify model designations as 

published in the most recent type 

certificate data sheet for the affected 

models. For ATR72 airplanes, the type 

certificate data sheet designations are as 

follows: Model ATR72–101, –102, –201, 

–202, –211, –212, and –212A airplanes. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule with the change described 

previously and 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. 

The FAA also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this final rule. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0173 describes new 

or more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires ATR ATR72 

Time Limits Document, Revision 16, 

dated January 30, 2018, which the 

Director of the Federal Register 


khammond on DSKJM1Z7X2PROD with RULES
11104 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Rules and Regulations 

approved for incorporation by reference 

as of August 26, 2019 (84 FR 35028, July 

22, 2019). 

This material 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 23 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2019–13–04 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. In the past, 

the agency has estimated that this action 

takes 1 work-hour per airplane. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 727 series 

airplanes. This AD was prompted by a 

determination that excessive sealant 

coating on internal wing Structural 

Significant Items (SSIs) may not reveal 

cracks during inspections required by 

AD 98–11–03 R1. This AD requires 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate inspections that will give no 

less than the required damage tolerance 

rating (DTR) for certain SSIs of the wing. 

This AD also requires repetitive 

inspections for cracking of the affected 

SSIs and repair if necessary. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 31, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 31, 2021.

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 all The Boeing Company Model 

727 airplanes. The NPRM published in 

the Federal Register on November 27, 

2020 (85 FR 75969). The NPRM was 

prompted by a determination that 

excessive sealant coating on internal 

wing SSIs may not reveal cracks during 

inspections required by AD 98–11–03 

R1, Amendment 39–10983 (64 FR 989, 

January 7, 1999) (AD 98–11–03 R1). The 

NPRM proposed to require revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

inspections that will give no less than 

the required DTR for certain SSIs of the 

wing. The NPRM also proposed to 

require repetitive inspections for 

cracking of the affected SSIs and repair 

if necessary. 

The FAA is issuing this AD to address 

excessive sealant coating on internal 

wing SSIs that may prevent the 

detection of cracks during inspections. 

This condition, if not addressed, could 

result in propagation of structural cracks 

that could lead to the inability of a wing 

SSI to sustain limit load and result in 

loss of control of the airplane. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA has considered 

the comment received. Boeing indicated 

its support for the NPRM. 

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
