Airworthiness Directives; FiberglasTechnik Rudolf Lindner GmbH & Co. 

KG Gliders 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Fiberglas-Technik Rudolf Lindner 

GmbH & Co. KG Models G103 TWIN 

ASTIR, G103 TWIN II, and G103A 

TWIN II ACRO gliders. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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 a broken bell-crank 

installed in the air brake control system. 

We are issuing this AD to require 

actions to address the unsafe condition 

on these products. 

DATES: This AD is effective December 4, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of December 4, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to add an AD that would apply 

to all Fiberglas-Technik Rudolf Lindner 

GmbH & Co. KG Models G103 TWIN 

ASTIR, G103 TWIN II, and G103A 

TWIN II ACRO gliders. The NPRM was 

published in the Federal Register on 

August 10, 2015 (80 FR 47871). The 

NPRM proposed to correct an unsafe 

condition for the specified products and 

was based on mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country. The MCAI states: 

A report was received concerning a broken 

bell-crank, installed in the air brake control 

circuit approximately 1.4 m outside the wing 

root rib of a GROB G 103 Twin II sailplane. 

Preliminary investigation results revealed 

additional cases of cracks on the same part, 

installed in the air brake control systems of 

the early Twin II type design. 

The same bell-cranks are also installed at 

the same location in the control systems of 

other models belonging to the same type 

design (see list of affected models under 

Applicability). 

This condition, if not detected and 

corrected, could lead to failure of the air 

brake system, possibly resulting in reduced 

control of the sailplane. 

To address this potential unsafe condition, 

Fiberglas-Technik issued Technische 

Mitteilung (TM)/Service Bulletin (SB) TM– 

G08/SB–G08 (one document) and Anweisung 

(A)/Instructions (I) A/I–G08 (one document) 

to provide instructions for a check of the air 

brake locking forces, the inspection of the 

bell-crank and, if cracks are found, 

replacement of the bell-crank. 

Additionally, TM–G07/SB–G07 (one 

document) and A/I–G07 (one document) 

provide instructions for the installation of 

inspection openings in the wing of GROB G 

103 TWIN II and G 103 A TWIN II ACRO 

sailplanes to facilitate the inspection of the 

bell-crank. (For the TWIN ASTIR and TWIN 

ASTIR TRAINER sailplanes, such an opening 

is required by LBA AD 92–190/2 (GROB SB 

315–45/2.) This installation is optional for 

sailplanes not exceeding the original 

intended life limit. 

For the reason described above, this AD 

requires a check of the air brake locking 

forces, an inspection for cracks in the air 

brake control unit and, if cracks are found, 

replacement of the affected flight control 

system parts. This AD is a temporary 

measure and further AD action may follow. 

The MCAI can be found in the AD 

docket on the Internet at http://

www.regulations.gov/

#!documentDetail;D=FAA-2015-3300- 

0003. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request Credit for Certain Inspections 

Done Before AD Was Issued 

William Tisdale requested that the AD 

give credit for inspections that were 

done following Fiberglas-Technik 

Rudolf Lindner Service Bulletin (SB– 

G08), Edition April 24, 2015; and 

Fiberglas-Technik Rudolf Lindner 

Anweisung (English translation: 

Instructions), (A/I–G08), Ausgabe 

(English translation: Edition) April 24, 

2015, within the year before the AD 

being issued as meeting the initial 

inspection requirement for both the 

tension and crack inspection. 

We infer that the commenter made 

this request in order to prevent 

duplication of work already done. 

We agree with the commenter. In 

paragraph (f) of this AD, the first 

sentence reads, ‘‘Unless already done, 

do the following actions:.’’ This 

sentence gives compliance credit to 

owners/operators of the affected gliders 

for actions required by this AD that have 

already been done before the effective 

date of this AD, if done following the 

service information required by this AD. 

Because the requested change is 

already part of this AD, we have not 

changed the final rule AD action based 

on this comment. 

Request to Use Lighted Borescope To 

Inspect the Bell-Crank 

William Tisdale requested the use of 

a lighted borescope from either the wing 

rib root or access through the spoiler 

box push rod opening to inspect the 

bell-crank. 

We infer that the commenter wants us 

to incorporate into the AD an allowance 

to use a lighted borescope to do the 

inspection of the bell-crank installed in 

the air brake control system. 

We agree with the commenter about 

using a lighted borescope for the 

inspection from the wing rib root as it 

is already allowed in Fiberglas-Technik 

Rudolf Lindner Service Bulletin (SB– 

G08), Edition April 24, 2015; and 

Fiberglas-Technik Rudolf Lindner 

Anweisung (English translation: 

Instructions), (A/I–G08), Ausgabe 

(English translation: Edition) April 24, 

2015. In the service information it 

states, ‘‘This inspection is done using an 

endoscope or small camera working 


Lhorne on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 80, No. 210 / Friday, October 30, 2015 / Rules and Regulations 66791 

through the wing root rib or using a 

mirror when working through an 

inspecting opening.’’ An endoscope 

consists of an optical system with a high 

intensity light source and is sometimes 

referred to as a borescope. 

We disagree with the commenter with 

using a lighted borescope to do the 

inspection by accessing the area through 

the spoiler box push rod opening since 

this procedure is not specified in the 

required service information. The 

commenter may request an alternative 

method of compliance (AMOC) for this 

process. The request, including all 

substantiating data, may be submitted 

following 14 CFR 39.19 as specified in 

paragraph (g)(1) of this AD. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (80 FR 

47871, August 10, 2015) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 47871, 

August 10, 2015). 

Related Service Information Under 1 

CFR Part 51 

We reviewed Fiberglas-Technik 

Rudolf Lindner Service Bulletin (SB– 

G08), Edition April 24, 2015; and 

Fiberglas-Technik Rudolf Lindner 

Anweisung/(English translation: 

Instructions), (A/I–G08), Ausgabe 

(English translation: Edition) April 24, 

2015. The service information describes 

procedures for inspecting the air brake 

locking forces; inspecting the bell-crank; 

and, if cracks are found during the 

inspections, replacing the bell-crank. 

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 of 

the AD. 

Interim Action 

We consider this AD interim action. 

The design approval holder is working 

toward a terminating action for the 

repetitive inspections. We may take 

further AD action in the future. 

Costs of Compliance 

We estimate that this AD will affect 

106 products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $18,020, or $170 per product. 

In addition, we estimate that any 

necessary follow-on actions will be as 

follows: 

• Replacement of bell-crank will take 

about 5 work-hours per product. 

Required parts will cost about $566 for 

a total of $991 per product. 

• Installation of optional inspection 

openings will take about 15 work-hours 

per product. Required parts will cost 

about $1,004 for a total of $2,279 per 

product. 

We have no way of determining the 

number of products that may need these 

actions. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to the FAA at 800 

Independence Ave. SW., Washington, 

DC 20591. ATTN: Information 

Collection Clearance Officer, AES–200. 

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. 

Regulatory Findings 

We 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 this AD: 

(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.

(e) Reason 

This AD was prompted by 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 a broken 

bell-crank installed in the air brake control 

system. We are issuing this AD to detect and 

correct a broken bell-crank which could lead 

to failure of the air brake system, possibly 

resulting in reduced control. 

(f) Actions and Compliance 

Unless already done, do the following 

actions: 

(1) Within 30 days after December 4, 2015 

(the effective date of this AD) and repetitively 

thereafter at intervals not to exceed 12 

months, inspect the locking forces of the air 

brake control unit, and, if any discrepancy is 

found, before further flight, correct the 

locking forces. Do the inspection and 

correction of any discrepancy following the 

instructions of Fiberglas-Technik Rudolf 

Lindner Service Bulletin (SB–G08), Edition 

April 24, 2015; and Fiberglas-Technik Rudolf 

Lindner Anweisung (English translation:

translation: Edition) April 24, 2015. 

Note 2 to paragraph (f)(2) of this AD: In 

the lower wing surface inspection, openings 

near the bell-crank may be installed to 

simplify the inspection and make a possible 

replacement of the bell-crank possible. This 

optional installation is described in GROB 

Luft Und Raumfahrt Service Bulletin 315–45/ 

2, dated December 21, 1995; and FiberglasTechnik Rudolf Lindner Service Bulletin 

(SB–G07), Edition April 24, 2015.
