Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for all Extra Aerobatic Aircraft GmbH (Extra) Model EXTRA NG airplanes. This proposed AD was prompted by reports of the canopy opening or detaching in flight because of a partially or improperly locked canopy. This proposed AD would require replacing the canopy placards and revising the Limitations Section of the Pilot Operating Handbook/ Airplane Flight Manual (POH/AFM). The FAA is proposing this AD to address the unsafe condition on these products.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Doug 
Rudolph, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2025-0156, dated July 21, 2025 (EASA AD 2025-0156) (also 
referred to as the MCAI), to correct an unsafe condition on Extra 
Aerobatic Aircraft GmbH Model EXTRA NG airplanes, all serial numbers. 
The MCAI states that there are reports of canopies opening or detaching 
during flight. Further investigation determined that, in most cases, 
the root cause was a partially or improperly locked canopy. This 
condition, if not detected and corrected, could result in canopy 
separation, possibly leading to damage to the airplane structure, loss 
of control of the airplane, or injuries to people on the ground.
    To address the unsafe condition, the MCAI requires replacing the 
canopy placards and revising the Limitations Section by adding 
reference to new canopy placards in the POH/AFM. This can be 
accomplished by incorporating Revision 16 or later of the Extra 
Aerobatic Aircraft GmbH POH/AFM.
    You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under 
Docket No. FAA-2025-5386.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EXTRA Aerobatic Aircraft GmbH Service Bulletin No. 
SB-NG-1-24, Issue A, dated December 19,

[[Page 57169]]

2024. This material specifies procedures for revising the Limitations 
Section of the POH/AFM to include the newly mandated placard. 
Compliance shall be accomplished by incorporating Revision 16 or later 
approved revisions of the POH/AFM. 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.

FAA's Determination

    These products have been approved by the civil aviation authority 
of another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, that authority has notified the FAA of the unsafe condition 
described in the MCAI and material referenced above. The FAA is issuing 
this NPRM after determining that the unsafe condition described 
previously is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the material already described. This proposed AD also requires 
revising the Limitations Section of the existing POH/AFM.
    The owner/operator (pilot) holding at least a private pilot 
certificate may revise the existing POH/AFM, as applicable, for your 
airplane and must enter compliance with the applicable paragraph of 
this proposed AD into the airplane maintenance records in accordance 
with 14 CFR 43.9(a) and 91.417(a)(2)(v).

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 30 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.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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

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:

Extra Aerobatic Aircraft GmbH: Docket No. FAA-2025-5386; Project 
Identifier MCAI-2025-01227-A.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by January 26, 2026.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Extra Aerobatic Aircraft GmbH Model EXTRA NG 
airplanes, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 1100, Placards and 
Markings

(e) Unsafe Condition

    This AD was prompted by reports of the canopy opening or 
detaching in flight because of a partially or improperly locked 
canopy. The FAA is issuing this AD to detect and address placards/
design that did not provide adequate positive canopy locking or 
confirmation. The unsafe condition, if not addressed, could result 
in canopy separation, possibly leading to damage to the airplane 
structure, loss of control of the airplane, or injuries to people on 
the ground.

(f) Compliance

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

(g) Required Actions

    (1) For airplanes without canopy placard part number (P/N) EX-
01106.01-Canopy installed, within 3 months or 25 hours time-in-
service, whichever occurs first after the effective date of this AD, 
replace the affected canopy placards at the front and rear canopy 
handles in accordance with the INSTRUCTIONS, steps 1 and 2, in EXTRA 
Aerobatic Aircraft GmbH Service Bulletin No. SB-NG-1-24, Issue A, 
dated December 19, 2024 (EXTRA SB-NG-1-24).
    (2) Before next flight, after the replacement of the affected 
canopy placards required by paragraph (g)(1) of this AD, revise the 
Limitations Section of the existing pilot's operating handbook/
airplane flight manual (POH/AFM) to include canopy placard P/N EX-
01106.01-Canopy in accordance with the

[[Page 57170]]

INSTRUCTIONS, step 3, in EXTRA SB-NG-1-24. The owner/operator 
(pilot) holding at least a private pilot certificate may revise the 
existing POH/AFM for your airplane and must enter compliance with 
the applicable paragraph of this AD into the airplane maintenance 
records in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v).
    (3) Amending the existing POH/AFM by incorporating a later POH/
AFM revision that includes information identical to that required by 
paragraph (g)(2) is an acceptable method to comply with the 
requirements of paragraph (g)(2) of this AD.

(h) Installation Prohibition

    As of the effective date of this AD, do not replace any canopy 
placard with a placard that is not P/N EX-01106.01-Canopy.

(i) Alternative Methods of Compliance (AMOCs)

    The Manager, International Validation 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 International Validation Branch, send
