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 defective starter solenoid. 

We are issuing this proposed AD to 

require actions to address the unsafe 

condition on these products.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2014– 

0212, dated September 19, 2014 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for certain 

Grob-Werke Models G115EG and G120A 

airplanes. The MCAI states: 

An operator of a G 115E aeroplane 

experienced a total loss of electrical power in 

flight. The root cause was found to be a 

defective starter solenoid causing an internal 

short circuit, which resulted in breakdown of 

the system voltage. 

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 Service Bulletin 

(SB) MSB1078–196 for G 115 aeroplanes and 

SB MSB1121–144 for G 120 aeroplanes to 

provide instructions for inspection and 

corrective action. 

For the reason described above, this AD 

requires a one-time inspection of the starter 

solenoid and, depending on the findings, 

replacement of the starter. 

A technical solution is currently under 

development and further AD action may 

follow. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2014–0848. 

Relevant Service Information 

GROB Aircraft has issued Service 

Bulletin No. MSB1078–196 and Service 

Bulletin No. MSB1121–144, both dated 

July 14, 2014. The actions described in 

this service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This 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. 

Interim Action 

We consider this proposed AD 

interim action. GROB Aircraft is 

currently working on a final technical 

solution to resolve the unsafe condition. 

If final action is later identified, we 

might consider further rulemaking. 

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 4 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 205 / Thursday, October 23, 2014 / Proposed Rules 63341 

Based on these figures, we estimate 

the cost of this proposed AD on U.S. 

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

product. 

In addition, we estimate that any 

necessary follow-on actions would 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 these actions. 

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 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

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. Amend § 39.13 by adding the 

following new AD: 

Grob-Werke: Docket No. FAA–2014–0848; 

Directorate Identifier 2014–CE–031–AD. 

(a) Comments Due Date 

We must receive comments by December 8, 

2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to GROB–WERKE Model 

G115EG airplanes, all serial numbers through 

82323/E, and Model G120A airplanes, all 

serial numbers through 85063, certificated in 

any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 80: Starting. 

(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 defective 

starter solenoid. We are issuing this AD to 

detect and correct defective starter solenoids, 

which could cause an internal short circuit 

and could result in reduced control. 

(f) Actions and Compliance 

Unless already done, do the actions in 

paragraphs (f)(1) and (f)(2) of this AD: 

(1) Within the next 30 days after the 

effective date of this AD, inspect the starter 

following the Accomplishment Instructions 

in GROB Aircraft Service Bulletin No. 

MSB1078–196, dated July 14, 2014, or GROB 

Aircraft Service Bulletin No. MSB1121–144, 

dated July 14, 2014, as applicable. 

(2) If any damage is found on the starter 

during the inspection required in paragraph 

(f)(1) of this AD, before further flight, replace 

the starter with a serviceable part. Do the 

replacement following the Accomplishment 

Instructions in GROB Aircraft Service 

Bulletin No. MSB1078–196, dated July 14, 

2014, or GROB Aircraft Service Bulletin No. 

MSB1121–144, dated July 14, 2014, as 

applicable. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. Send information to

329–4090; email: karl.schletzbaum@faa.gov. 

Before using any approved AMOC on any 

airplane to which the AMOC applies, notify 

your appropriate principal inspector (PI) in 

the FAA Flight Standards District Office 

(FSDO), or lacking a PI, your local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they
