in accordance with AD 2017–15–06: Before 

the MLG accumulates 900 flight cycles since 

the last inspection or within 150 flight cycles 

after the effective date of this AD, whichever 

occurs later, and thereafter at intervals not to 

exceed 900 flight cycles. 

(ii) For airplanes that have not been 

inspected in accordance with AD 2017–15– 

06: Before the MLG accumulates 8,000 flight 

cycles since first installation on an airplane 

or within 50 flight cycles after the effective 

date of this AD, whichever occurs later, and 

thereafter at intervals not to exceed 900 flight 

cycles. 

(2) If any crack is found during any 

inspection required by paragraph (g)(1) of 

this AD, before further flight, replace the 

MLG with an airworthy MLG and continue 

the inspections as required by paragraph 

(g)(1) of this AD. 

(3) The compliance times in paragraphs 

(g)(1)(i) and (ii) of this AD are presented in 

flight cycles (landings). If the number of total 

flight cycles is unknown, for purposes of this 

AD, the number of flight cycles is the hours 

time-in-service (TIS) accumulated on the 

airplane multiplied by 0.75. For example:

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 75–23–03, 

Amendment 39–2414 (40 FR 50706, 

October 31, 1975) (AD 75–23–03). AD 

75–23–03 applied to all Alexander 

Schleicher Model Ka2B, Ka 6, Ka 6 B, 

Ka 6 BR, Ka 6 C, Ka 6 CR, K 7, K 8, and 

AS–K 13 gliders. AD 75–23–03 required 

visually inspecting the glue joint 

between the elevator nose rib number 1 

and the nose plywood skin and 

replacing the glue joint if insufficient 

glue adhesion was found. 

The NPRM published in the Federal 

Register on March 28, 2022 (87 FR 

17204). The NPRM was prompted by 

AD 2021–0230, dated October 14, 2021 

(referred to after this as ‘‘the MCAI’’), 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union. The MCAI states: 

An occurrence was reported of structural 

failure of an elevator during winch launching 

of a K 7 sailplane. Subsequent investigation 

results determined that the occurrence was 

due to damaged glue of the elevator’s rib No. 

1. 

This condition, if not detected and 

corrected, could affect the structural integrity 

of an elevator, possibly resulting in reduced 

control of the aeroplane. 

To address this potential unsafe condition, 

Schleicher issued the glued joint inspection 

TN [Technical Note], as defined in this 

[EASA] AD, to provide inspection 

instructions and LBA Germany issued AD 

72–7 (later revised) to require those actions. 

Since that [LBA Germany] AD was issued, 

additional similar occurrences were reported 

of structural elevator failure, also on 

(powered) sailplanes originally not affected 

by LBA 72–7/3. Prompted by this 

development, Schleicher issued the 

applicable TN, providing inspections 

instructions for all (powered) sailplanes 

having an elevator of a similar design and 

making the inspections dependent also on 

the number of take-offs. 

For the reason described above, this 

[EASA] AD supersedes LBA Germany AD 

72–7/3 [dated December 13, 1989] and 

requires repetitive inspections of the elevator 

and, depending on findings, accomplishment 

of applicable corrective action(s). 

In the NPRM, the FAA proposed to 

require repetitively inspecting the glue 

joint between elevator rib number 1 and 

the plywood skin and repairing if 

necessary. In the NPRM, the FAA also 

proposed to add Model K 8 B gliders to 

the applicability. The FAA is issuing 

this AD to prevent structural failure of 

an elevator, which could lead to loss of 

glider control.

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0293. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These products have been approved 

by the 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, 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 the AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. This AD is adopted as 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Alexander 

Schleicher GmbH & Co. 

Segelflugzeugbau Appendix 01–2021, 

Flight and Operating Manual, dated 

March 1, 2021. This service information 

specifies procedures for protecting the 

glider from moisture and repetitively 

inspecting the glue joint between 

elevator rib number 1 and the plywood 

skin. 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. 

Differences Between This AD and the 

MCAI 

The MCAI applies to Model ASK 16, 

ASK 16B, ASK 18, ASK 18 B, K 8 C, and 

Ka 6/0 gliders, and this AD does not 

because they do not have an FAA type 

certificate. 

This AD includes the Model Ka2B 

glider whereas the MCAI does not. 

Although the technical notes required 

by the MCAI specify to report findings 

of damage to the manufacturer, this AD 

does not require that action. 

Costs of Compliance 

The FAA estimates that this AD 

affects 83 gliders of U.S. registry. The 

FAA also estimates that it will take 4 

work-hours per glider to inspect the 

glue joint at elevator rib number 1 and 

requires parts costing $50. The average 

labor rate is $85 per work-hour. 

Based on these figures, the FAA 

estimates the cost on U.S. operators to 

be $32,370 or $390 per glider, per 

inspection cycle. 

The FAA estimates that replacing the 

glue joint, if necessary, takes 8 workhours and requires parts costing $250 

for an estimated cost of $930 per glider. 

The FAA has no way of determining the 

number of gliders that may need this 

action. 

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 has determined that 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.
