Airworthiness Directives; DG Aviation GmbH (Type Certificate 
Previously Held by DG Flugzeugbau GmbH) 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 DG Aviation GmbH (type certificate previously held by DG 
Flugzeugbau GmbH) Model DG-400 gliders and all Model DG-500 Elan Orion, 
DG-500 Elan Trainer, DG-500/20 Elan, DG-500/22 Elan, DG-500M, DG-500MB, 
DG-800A, DG-800B, DG-808C, DG-1000M, DG-1000S, and DG-1000T gliders. 
This AD was prompted by a report of a broken rod end at the upper end 
of the elevator pushrod in the fin (vertical tail) of a DG Aviation 
GmbH Model DG-300 glider. Depending on the glider model, this AD 
requires revising your existing glider maintenance manual to 
incorporate new procedures for elevator control circuit free play 
adjustment, performing an operational check of the free play adjustment 
of the automatic elevator hook-up, accomplishing corrective actions as 
required, and replacing the elevator pushrod end with a new part. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective October 15, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 15, 
2024.

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 2024-0126, dated July 2, 2024 (EASA AD 2024-0126) (also 
referred to as the MCAI), to correct an unsafe condition on the 
following DG Aviation GmbH sailplanes (gliders):
    <bullet> Model DG-100G, DG-100G ELAN, DG-200, DG-200/17, DG-200/
17C, DG-300, DG-300 ELAN, DG-300 Club ELAN, DG-300 ELAN ACRO, DG-300 
Club ELAN ACRO, DG-400, DG-600, DG-600/18, DG-600M, and DG-600/18 M 
sailplanes and powered sailplanes, all serial numbers except those 
equipped with l'Hotellier connections of the elevator control.
    <bullet> Model DG-500/22 ELAN, DG-500 ELAN Trainer, DG-500/20 ELAN, 
DG-500 ELAN ORION, DG-500 M, and DG-500 MB sailplanes and powered 
sailplanes, all serial numbers.
    <bullet> Model DG-800 A, DG-800 B, DG-808C, DG-800 LA, DG-800 S, 
and DG-808 S sailplanes and powered sailplanes all serial numbers.
    <bullet> Model DG-1000S, DG-1000T, DG-1000M, and DG-1000E 
sailplanes and powered sailplanes, all serial numbers.
    The MCAI states an occurrence was reported of a broken rod end at 
the upper end of the elevator pushrod in the fin of a Model DG-300 
sailplane. It was determined that the elevator play adjustment screw 
was screwed in too far, which caused jamming of the roller inside the 
funnel. Even with higher force, the roller could not be moved up to the 
front of the funnel; therefore, each time, when rigging and during 
normal operation, a bending force affected the rod end, causing fatigue 
failure. Further investigation revealed that a significant number of 
certain sailplane models were operated with the elevator play 
adjustment screw screwed in too far. It was also determined that 
because of its location, the elevator pushrod end damage could not be 
detected using visual or non-destructive testing to identify fatigue 
cracks. This condition, if not detected and corrected, could lead to 
loss of pitch control of the (powered) sailplane. Due to the similarity 
of design, all DG sailplanes in the applicability of the MCAI (if 
equipped with automatic hook-up) could be affected by the unsafe 
condition.
    The MCAI requires a one-time operational check of the free play 
adjustment of the automatic elevator hook-up and, depending on the 
findings, replacement of the affected parts, and for a certain group of 
(powered) sailplanes, mandatory replacement of the rod end. The MCAI 
also requires following revised applicable Maintenance Manual tasks.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2316.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed the following material that specifies revising 
your existing glider maintenance manual and specifies procedures for 
accomplishing an operational check of the free play of the automatic 
elevator hook-up and installing new elevator pushrod ends and new 
elevator rollers and adjusting the free play, as applicable. These 
documents are distinct since they apply to different glider models.

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 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 and material referenced above. The FAA is issuing this AD 
after determining that 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 
material already described, except as discussed under ``Differences 
Between this AD and the MCAI.''

Differences Between This AD and the MCAI

    The MCAI applies to Model DG-100G, DG-100G ELAN, DG-200, DG-200/17, 
DG-200/17C, DG-300, DG-300 ELAN, DG-300 Club ELAN, DG-300 ELAN ACRO, 
DG-300 Club ELAN ACRO, DG-600, DG-600/18, DG-600M, DG-600/18 M, DG-800 
LA, DG-800 S, DG-808 S, and DG-1000E gliders, but this AD does not 
because these models do not have an FAA type certificate.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(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 forgoing notice and comment prior to adoption of this rule 
because operating a glider with the elevator play adjustment screw 
screwed in too far could lead to a loss of pitch control of the glider 
and loss of the ability to control the glider in flight or during 
landing. The FAA has determined that certain gliders will need an 
operational check within 3 months and immediate action if any 
discrepancy is found and certain other

[[Page 79427]]

gliders will need replacement of an affected part within 3 months after 
the effective date of this AD. This compliance time is shorter than the 
time necessary for the public to comment and for publication of the 
final rule.
    Accordingly, notice and opportunity for prior public comment are 
impracticable and contrary to the public interest pursuant to 5 U.S.C. 
553(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 forgo notice and 
comment.

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 the 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 101 gliders of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

    The FAA estimates the following costs to do any necessary elevator 
roller replacement (both Group 1 and Group 2 gliders) or elevator rod 
replacement (Group 2 gliders) that would be required based on the 
results of the operational check. The agency has no way of determining 
the number of gliders that might need these replacements:

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.
