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 certain GROB–WERKE Models 

G115EG and G120A airplanes. That 

NPRM was published in the Federal 

Register on February 26, 2015 (80 FR 

10423), and proposed to supersede AD 

2014–26–04, Amendment 39–18055 (80 

FR 155, January 5, 2015). 

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: 

An operator of a G 115E aeroplane 

experienced a total loss of electrical power in 

flight. The investigation found that a 

defective starter solenoid had caused an 

internal short circuit which resulted in 

breakdown of the system voltage. 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 80, No. 91 / Tuesday, May 12, 2015 / Rules and Regulations 27073 

This condition, if not detected and 

corrected, could result in reduced control of 

the aeroplane. 

To address this potential unsafe condition, 

GROB Aircraft AG issued Mandatory Service 

Bulletin (MSB) MSB1078–196 for G 115 

aeroplanes and MSB 1121–144 for G 120 

aeroplanes to provide instructions for 

inspection and corrective action. 

Consequently, EASA issued AD 2014–0212 

to require a one-time inspection of the starter 

solenoid and, depending on findings, 

replacement of the starter. In addition, for G 

115E aeroplanes, installation of a placard was 

required. 

More recently, GROB Aircraft AG 

developed a modification to avoid loss of 

electrical power in case of electrical shortage 

in the starter solenoid, which was published 

in revised GROB MSB1078–196/1 and 

MSB1121–144/1. 

Prompted by this development, EASA 

issued AD 2015–0010, retaining the 

requirements of EASA AD 2014–0212, which 

was superseded, and required installation of 

a starter relay. 

Since that AD was issued, operator 

comments have indicated the existence of a 

logistical problem, resulting in the 

unnecessary grounding of aeroplanes. 

For the reason described above, this AD is 

revised to amend paragraph (3), extending 

the compliance time for modification. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov/

#!documentDetail;D=FAA-2015-0415- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 10423, February 26, 2015) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data 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 

10423, February 26, 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 10423, 

February 26, 2015). 

Relevant Service Information Under 1 

CFR Part 51 

We reviewed GROB Aircraft Service 

Bulletin No. MSB1078–196, dated July 

14, 2014; GROB Aircraft Service 

Bulletin No. MSB1078–196/1, dated 

December 1, 2014; GROB Aircraft 

Service Bulletin No. MSB1121–144, 

dated July 14, 2014; and GROB Aircraft 

Service Bulletin No. MSB1121–144/3, 

dated February 20, 2015. The service 

information describes procedures for 

inspecting the starter solenoid, 

replacing damaged starters, and 

installing a starter relay. This 

information is reasonably available at 

http://www.regulations.gov by searching 

for and locating Docket No. FAA–2015– 

0415, or you may see ADDRESSES for 

other ways to access this service 

information. 

Costs of Compliance 

We estimate that this AD will affect 6 

products of U.S. registry. We also 

estimate that it will take about 4 workhours per product to comply with the 

basic starter inspection requirement of 

this AD. The average labor rate is $85 

per work-hour. 

Based on these figures, we estimate 

the cost of this inspection on U.S. 

operators to be $2,040, or $340 per 

product. 

In addition, we estimate that any 

necessary starter replacements will take 

about 4 work-hours and require parts 

costing $600, for a cost of $940 per 

product. We have no way of 

determining the number of products 

that may need this replacement. 

We also estimate that it will take 

about 20 work-hours per product to 

comply with the starter relay 

installation requirement of this AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $1,000 

per product. 

Based on these figures, we estimate 

the cost of this proposed installation on 

U.S. operators to be $16,200, or $2,700 

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. 

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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0415; or in person at the Docket 

Management Facility between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Office (telephone (800) 647– 

5527) is in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.
