(Type Certificate Previously Held by 

Stemme GmbH & Co. KG) Gliders 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Stemme AG (type certificate previously 

held by Stemme GmbH & Co. KG) Model 

Stemme S 12 gliders. This AD was 

prompted by mandatory continuing 

airworthiness information (MCAI) 

issued by the aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI identifies the unsafe 

condition as a deviation in the 

construction of the connection of the 

inner wing to the outer wing, resulting 

in a wrong positioning of the glass-fiber 

reinforced plastic (GFRP) blocks. This 

AD requires inspecting the left-hand 

(LH) and right-hand (RH) outer wing 

spars for correct positioning of the GFRP 

blocks and, if incorrect positioning is 

found, repairing of the reinforcement 

blocks. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective July 26, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 26, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA 

Emergency AD 2022–0101–E, dated 

June 2, 2022 (referred to after this as 

‘‘the MCAI’’), to address an unsafe 

condition on certain serial-numbered 

Stemme AG Model Stemme S12 

powered sailplanes (gliders). The MCAI 

states: 

An occurrence was reported by the 

production line of the Stemme S12 of finding 

a deviation in the construction of the 

connection of the inner wing to the outer 

wing, resulting in a wrong positioning of the 

glass-fibre reinforced plastic (GFRP) blocks in 

the outer wing spar. 

This condition, if not corrected, could lead 

to loss of structural integrity at the joint 

(connection) between the outer wing and 

inner wing, possibly resulting in rupture of 

the affected wing, with consequent loss of 

control of the sailplane. 

To address this potential unsafe condition, 

Stemme identified the sailplanes possibly 

affected by this unintended production 

deviation and issued the SB [service 

bulletin], as defined in this [EASA] AD, to 

provide instructions to determine the 

(correct) positioning of the GFRP blocks in 

the outer wing spars. 

For the reasons described above, this 

[EASA] AD requires a one-time inspection of 

each affected part and, depending on 

findings, accomplishment of applicable 

corrective action(s). 

This [EASA] AD is considered to be an 

interim action and further AD action may 

follow. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0809. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Stemme 

Procedural Instruction P320–912060, 

Revision 00, dated May 20, 2022. This 

service information specifies procedures 

for inspecting the LH and RH outer wing 

spars for correct positioning of the GFRP 

reinforcement blocks, including sealing 

the inspection holes. 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 ADDRESSES. 

Other Related Service Information 

The FAA also reviewed Stemme 

Service Bulletin P062–980060, Revision 

00, dated May 20, 2022. This service 

information specifies inspecting the LH 

and RH outer wing spars for correct 

positioning of the GFRP reinforcement 

blocks by following Stemme Procedural 

Instruction P320–912060, Revision 00, 

dated May 20, 2022. This service 

information also prohibits operation and 

informing Stemme AG if incorrect 

positioning is found. 

FAA’s Determination 

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 issuing 

this AD because it has determined the 

unsafe condition described previously is 

likely to exist or develop on other 

products of the same type design. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the service 

information already described, except as 

discussed under ‘‘Differences Between 

this AD and the MCAI.’’ 

Differences Between This AD and the 

MCAI 

The MCAI specifies contacting 

Stemme for approved corrective action 

instructions, and this AD requires using 

a repair method approved by the FAA, 

EASA, or Stemme AG’s Design 

Organization Approval. 

Interim Action 

The FAA considers this AD to be an 

interim action. The design approval 

holder is currently developing a 

modification that will address the 

unsafe condition identified in this AD. 

Once this modification is developed, 

approved, and available, the FAA might 

consider additional rulemaking. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because loss of structural integrity 

between the inner and outer wing 

sections could cause a sudden rupture 

of the affected wing and consequent loss 

of glider control. Therefore, the 

inspection and any necessary repair 

must be accomplished before further 

flight. Accordingly, notice and 

opportunity for prior public comment 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 87, No. 131 / Monday, July 11, 2022 / Rules and Regulations 41051 

are impracticable and contrary to the 

public interest pursuant to 5 U.S.C. 

553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Comments Invited 

The FAA invites you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2022–0809 

and Project Identifier MCAI–2022– 

00711–G’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the final 

rule, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this final rule 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this final rule. 

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 AD 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 AD, 

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 AD. Submissions containing CBI 

should be sent to Jim Rutherford, 

Aviation Safety Engineer, General 

Aviation & Rotorcraft Section, 

International Validation Branch, FAA, 

901 Locust, Room 301, Kansas City, MO 

64106. Any commentary that the FAA 

receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because FAA 

has determined that it has good cause to 

adopt this rule without prior notice and 

comment, RFA analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 21 gliders of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

glider 

Cost on U.S. 

operators 

Inspect reinforcement blocks .............................. 2 work-hours × $85 per hour = $170 ................. $100 $270 $5,670 

The FAA estimates the following 

costs to replace reinforcement blocks on 

both sides, if required based on the 

results of the inspection. The FAA has 

no way of determining the number of 

gliders that might need this action: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per glider 

Replace both reinforcement blocks .............................. 16 work-hours × $85 per hour = $1,360 ...................... $1,000 $2,360 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.
