SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Schempp-Hirth 

Flugzeugbau GmbH Model Ventus-2a 

and Ventus-2b gliders. The NPRM 

published in the Federal Register on 

December 6, 2021 (86 FR 68937). The 

NPRM was prompted by 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 2020–0063, dated March 18, 

2020 (referred to after this as ‘‘the 

MCAI’’), to address an unsafe condition 

on Schempp-Hirth Flugzeugbau GmbH 

Models Ventus-2a, Ventus-2b, Ventus2c, Ventus-2cM, and Ventus-2cT gliders. 

The MCAI states: 

Severe corrosion has been found on the 

inboard flaperon actuation push rod of some 

sailplanes. Subsequent investigation 

determined that, when water ballast is 

dumped in flight, some water may be sucked 

into the wing upper side and enter the wing 

via the flaperon push rod. Intruding water 

may cause corrosion especially on the ball 

bearing connecting the flaperon push rod to 

the bell crank inside the wing. 

This condition, if not detected an[d] 

corrected, could lead to hard steering (when 

the ball bearing is damaged) or increased 

play (when the ball bearing has failed), 

possibly resulting in reduced control of the 

(powered) sailplane. 

To address this potential unsafe condition, 

Schempp-Hirth Flugzeugbau GmbH issued 

the [technical note] TN to provide inspection 

and replacement instructions. 

For the reason described above, this 

[EASA] AD requires repetitive inspections of 

the affected parts, as identified in the TN, 

and, depending on findings, replacement 

with serviceable parts. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

1019. 

In the NPRM, the FAA proposed to 

require compliance with the version of 

the TN (revision 2) identified in the 

MCAI. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Changes Made to This AD 

After the NPRM was issued, the FAA 

received a copy of Schempp-Hirth 

Flugzeugbau GmbH Working 

Instructions for Technical Note No. 

349–42/825–57, Revision 4, dated 

August 31, 2020. This revision of the TN 

provides clarification regarding the 

inspection area and instructions 

(including specifying that the mount is 

an affected part that must be inspected), 

the types of corrosion, and repair 

methods and instructions. This revision 

of the service information does not 

require additional work, because it does 

not impose any substantive changes to 

the procedures in revision 2. 

As a result, the FAA has revised 

paragraph (g) of this AD to specify that 

the mount is an affected part that must 

be inspected and to require compliance 

with Schempp-Hirth Flugzeugbau 

GmbH Working Instructions for 

Technical Note No. 349–42/825–57, 

Revision 4, dated August 31, 2020. The 

FAA has also added paragraph (h) of 

this AD to provide credit for work done 

before the effective date of the AD using 


khammond on DSKJM1Z7X2PROD with RULES
12560 Federal Register / Vol. 87, No. 44 / Monday, March 7, 2022 / Rules and Regulations 

Schempp-Hirth Flugzeugbau GmbH 

Working Instructions for Technical Note 

No. 349–42/825–57, Revision 2, dated 

February 24, 2020; or Schempp-Hirth 

Flugzeugbau GmbH Working 

Instructions for Technical Note No. 

349–42/825–57, Revision 3, dated 

March 31, 2020. Lastly, the FAA has 

revised the preamble of this final rule 

accordingly. 

Conclusion 

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 referenced above. The FAA 

reviewed the relevant data and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for the changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Schempp-Hirth 

Flugzeugbau GmbH Working 

Instructions for Technical Note No. 

349–42/825–57, Revision 4, dated 

August 31, 2020. This service 

information contains procedures for 

inspecting the pushrod, joint head, 

mount, and bell crank of the flaperon 

control of the wings for corrosion or 

other damage, and replacing or servicing 

(repair) if necessary. 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. 

Other Related Service Information 

The FAA also reviewed SchemppHirth Flugzeugbau GmbH Technical 

Note No. 349–42/825–57, Revision 4, 

dated August 31, 2020. This service 

information specifies inspecting the 

pushrod, joint head, mount, and bell 

crank of the flaperon control of the 

wings by following Schempp-Hirth 

Flugzeugbau GmbH Working 

Instructions for Technical Note No. 

349–42/825–57, Revision 4, dated 

August 31, 2020. 

Differences Between This AD and the 

MCAI 

The MCAI applies to Schempp-Hirth 

Flugzeugbau GmbH Model Ventus-2c, 

Ventus-2cM, and Ventus-2cT gliders, 

and this AD does not because they do 

not have an FAA type certificate. 

Costs of Compliance 

The FAA estimates that this AD 

affects 33 gliders of U.S. registry. The 

FAA also estimates that it would take 

about 1 work-hour per glider to comply 

with the inspection required by this AD. 

Based on these figures, the FAA 

estimates the inspection cost of this AD 

on U.S. operators to be $2,805 or $85 

per glider, per inspection cycle. 

In addition, the FAA estimates that 

each repair or replacement action 

required by this AD would take up to 8 

work-hours and require parts costing up 

to $800. Based on these figures, the FAA 

estimates the repair or replacement cost 

of this AD on U.S. operators to be up to 

$1,480 per glider. 

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 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.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 787–8, 787–9, and 787–10 

airplanes. The NPRM published in the 

Federal Register on October 6, 2021 (86 

FR 55538). The NPRM was prompted by 

significant changes, including new or 

more restrictive requirements, made to 

the AWLs related to fuel tank ignition 

prevention and the nitrogen generation 

system. In the NPRM, the FAA proposed 

to require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

The FAA is issuing this AD to address 

ignition sources inside the fuel tanks 

and increased flammability exposure of 

the fuel tanks caused by latent failures, 

alterations, repairs, or maintenance 

actions, which could result in a fuel
