ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus Defense and Space S.A. Model 

CN–235, CN–235–100, CN–235–200, 

and CN–235–300 airplanes and Model 

C–295 airplanes. This AD was prompted 

by cracks found on certain left- and 

right-hand stringers in a certain area of 

the fuselage. This AD requires repetitive 

inspections for cracking or broken rivets 

of certain left- and right-hand stringers 

and surrounding structure, and repair if 

necessary, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective March 30, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 30, 2021.

SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0159, dated July 16, 2020 (EASA 

AD 2020–0159) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Airbus Defense 

and Space S.A. Model CN–235, CN– 

235–100, CN–235–200, and CN–235– 

300 airplanes and Model C–295 

airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus Defense and Space 

S.A. Model CN–235, CN–235–100, CN– 

235–200, and CN–235–300 airplanes 

and Model C–295 airplanes. The NPRM 

published in the Federal Register on 

November 10, 2020 (85 FR 71583). The 

NPRM was prompted by cracks found 

on certain left- and right-hand stringers 

in a certain area of the fuselage. The 

NPRM proposed to require repetitive 

inspections for cracking or broken rivets 

of certain left- and right-hand stringers 

and surrounding structure, and repair if 

necessary, as specified in an EASA AD. 

The FAA is issuing this AD to address 

such cracking in the stringers, 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. 

Conclusion 

The FAA reviewed the relevant data 

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 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0159 describes 

procedures for repetitive detailed visual 

(DET) or high frequency eddy current 

inspections of the stringer P0a and P0a’ 

at the riveted line of the attachment to 

the gusset and along the stringer head, 

in particular at the area of the last 

attachment of the gusset to the stringer 

in the midpoint between frame (FR) 43 

and FR44, repetitive DET inspections 

for fatigue cracks of the fuselage skin, 

along the stringers’ footprint and 

surrounding structure and the 

attachment of the gusset to the FR43; 

repetitive DET inspections for fatigue 

cracks of the actuator bracket on FR43, 

along the radius of the vertical nerves, 

inner lug holes, and attachment holes of 

the bracket to FR43; repetitive DET 

inspections for fatigue cracks or broken 

rivets in the web and joint clips to skin 

and stringer of both sides of the frame 

between stringer P1d and P1d’ (two 

stringers for each side from the central 

stringer P0a); repetitive DET inspections 

for fatigue cracks or broken rivets of the 

gussets, along the flange which joins 

FR43; and repair of any cracking or 

broken rivets. 

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. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking then. 

Costs of Compliance 

The FAA estimates that this AD 

affects 8 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $1,360 

The FAA has received no definitive 

data that enables providing cost 

estimates for the on-condition action 

specified in this 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. 

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: 

10742 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 

(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.

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

2021–02–18 Airbus Defense and Space S.A. 

(Formerly Known as Construcciones 

Aeronauticas, S.A.): Amendment 39– 

21401; Docket No. FAA–2020–1020; 

Project Identifier MCAI–2020–00988–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective March 30, 2021.

Model C–295 airplanes, certificated in any 

category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Reason 

This AD was prompted by cracks found on 

certain left- and right-hand stringers in the

FAA is issuing this AD to address such 

cracking in the stringers, which could result 

in reduced structural integrity of the 

airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and

the effective date of this AD, whichever 

occurs later,’’ this AD requires using a 

compliance time of within 300 FH after the 

effective date of this AD. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2020–0159 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Other FAA AD Provisions 

The following provisions also apply to this 

AD:

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 Large Aircraft 

Section, International Validation Branch, 

send it to the attention of the person 

identified in paragraph (k) of this AD. 

Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any 

approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the responsible 

Flight Standards Office.
