AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2017–08– 

09 for DG Flugzeugbau GmbH Models 

DG–500MB gliders that are equipped 

with a Solo 2625 02 engine modified 

with a fuel injection system following 

the instructions of Solo Kleinmotoren 

GmbH Technische Mitteilung (TM)/ 

Service Bulletin (SB) 4600–3 ‘‘Fuel 

Injection System’’ and identified as Solo 

2625 02i. This proposed AD results from 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country to 

identify and correct an unsafe condition 

on an aviation product. The MCAI 

describes the unsafe condition as the 

potential of an in-flight shut-down and 

engine fire due to failure of the 

connecting stud for the two fuel injector 

mounts of the engine redundancy 

system on gliders equipped with a Solo 

2625 02i engine. This proposed AD adds 

the DG Flugzeugbau GmbH Model DG– 

1000M glider equipped with Solo 2625 

02i engines to the applicability. We are 

issuing this proposed AD to require 

actions to address the unsafe condition 

on these products.

Discussion 

We issued AD 2017–08–09, 

Amendment 39–18858 (82 FR 18694; 

April 21, 2017) (‘‘AD 2017–08–09’’). 

That AD required actions intended to 

address an unsafe condition on DG 

Flugzeugbau GmbH Model DG–500MB 

gliders and was based on mandatory 

continuing airworthiness information 

(MCAI) originated by the European 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Community. That 

MCAI is EASA AD No.: 2014–0269, 

dated December 11, 2014 (referred to 

after this as ‘‘the MCAI’’). 

Since we issued AD 2017–08–09, the 

FAA has now type certificated the DG 

Flugzeugbau GmbH Model DG–1000M 

glider and that glider model is equipped 

with a Solo 2625 02i engine. 

You may examine the MCAI on the 

internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2018–0014.

daltland on DSKBBV9HB2PROD with PROPOSALS
Federal Register / Vol. 83, No. 10 / Tuesday, January 16, 2018 / Proposed Rules 2089 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 6 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $67 per product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $912, or $152 per 

product. 

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. 

We are 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to small airplanes, gliders, 

balloons, airships, domestic business jet 

transport airplanes, and associated 

appliances to the Director of the Policy 

and Innovation Division. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Amendment 39–18858 (82 FR 

18694; April 21, 2017), and adding the 

following new AD: 

DG Flugzeugbau GmbH: Docket No. FAA– 

2018–0014; Product Identifier 2017–CE– 

044–AD. 

(a) Comments Due Date 

We must receive comments by March 2, 

2018. 

(b) Affected ADs 

This AD replaces AD 2017–08–09, 

Amendment 39–18858 (82 FR 18694; April 

21, 2017) (‘‘AD 2017–08–09’’). 

(c) Applicability 

This AD applies to DG Flugzeugbau GmbH 

DG–500MB and DG–1000M gliders, all serial 

numbers, certificated in any category, that 

are: 

(1) Equipped with a Solo 2625 02 engine 

modified with a fuel injection system 

following the instructions of Solo 

Kleinmotoren GmbH Service Bulletin (SB)/ 

Technische Mitteilung (TM) 4600–3 ‘‘Fuel 

Injection System’’ and identified as Solo 

2625 02i; or 

(2) equipped with a Solo 2625 02i engine 

at manufacture. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 72: Engine. 

(e) Reason 

This proposed AD results from mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and address an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as the 

potential of an in-flight shut-down and 

engine fire resulting in loss of control due to 

failure of the connecting stud for the two fuel 

injector mounts of the engine redundancy 

system on gliders equipped with a Solo 2625 

02i engine. We are issuing this AD to prevent 

such failure that could lead to the potential 

of an in-flight shut-down and engine fire and 

result in loss of control and to include 

recently FAA type-certificated DG 

Flugzeugbau GmbH Model DG–1000M 

gliders equipped with Solo 2625 02i engines. 

(f) Actions and Compliance 

(1) For DG Flugzeugbau GmbH Model DG– 

500MB gliders: Unless already done, within 

the next 60 days after May 26, 2017 (the 

effective date of AD 2017–08–09), modify the

Kleinmotoren GmbH Technische Mitteilung 

(English translation: Service Bulletin), Nr. 

4600–5, Ausgabe 2 (English translation: Issue 

2), dated December 12, 2014, stating ‘‘the 

actions have to be accomplished by a 

certified maintenance organization and must 

be released by certifying staff,’’ is not 

applicable to this AD. 

Note 1 to paragraph (f) of this AD: This 

service information contains German to 

English translation. The EASA used the 

English translation in referencing the 

document. For enforceability purposes, we 

will refer to the Solo Kleinmotoren service 

information as it appears on the document.

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2014–02– 

01, which applies to certain 

Bombardier, Inc., Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702), 

Model CL–600–2D15 (Regional Jet 

Series 705), and Model CL–600–2D24 

(Regional Jet Series 900) airplanes. AD 

2014–02–01 requires repetitive 

inspections of the rudder travel limiter 

(RTL) return springs and primary 

actuator, and corrective actions if 

necessary; and replacement of certain 

RTL return springs. Since we issued AD 

2014–02–01, we received reports that 

when installing the RTL return springs, 

the RTL limiter arm assembly lug can 

become deformed. This proposed AD 

would require an inspection of the RTL 

return springs for signs of chafing; an 

inspection of the casing of the primary 

actuator for signs of chafing or missing 

paint; replacement of the RTL return 

springs; and an inspection of the lugs of 

the RTL limiter arm assembly for cracks, 

and modification or replacement, as 

applicable; and applicable corrective 

actions. This proposed AD would also 

add airplanes to the applicability. We 

are proposing this AD to address the 

unsafe condition on these products. 

DATES: We must receive comments on 

this proposed AD by March 2, 2018.
