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.

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): 

• 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. 

• 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. 

• 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. 

• 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.

This material is reasonably available 

because the interested parties have

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 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 189 / Monday, September 30, 2024 / Rules and Regulations 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: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Revise glider maintenance manual (Group 1 and 

Group 2 gliders).

1 work-hour × $85 per 

hour = $85.

$0 85 8,585. 

Perform operational check of the free play adjustment of the automatic elevator hook-up (Group 1 

and Group 2 gliders).

1 work-hour × $85 per 

hour = $85.

0 85 8,585. 

Replace the elevator pushrod end (Group 1 gliders) 2 work-hours × $85 per 

hour = $170.

100 270 7,020 (26 gliders). 

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: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace the elevator roller with a new one and adjust free play (Group 

1 and Group 2 gliders).

2 work-hours × $85 per hour = 

$170.

150 320 

Replace the elevator pushrod end (Group 2 gliders) ................................ 2 work-hours × $85 per hour = 

$170.

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.
