Airworthiness Directives; Grob-Werke 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for GrobWerke Model G115EG airplanes. 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 cracks in the elevator trim 

tab arms on several Grob G 115 

airplanes, which could result in failure 

of the part and consequent loss of 

control. We are issuing this AD to 

require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective May 23, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 23, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on January 15, 2013 (78 FR 

2910). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

On several Grob G 115 aeroplanes, elevator 

trim tab arms Part Number (P/N) 115E–3758 

have been found cracked, from a rear 

mounting hole (either L/H or R/H) to the rear 

edge of the trim tab arm. 

This condition, if not detected and 

corrected, could lead to further crack 

propagation, possibly resulting in failure of 

the part and consequent loss of control of the 

aeroplane. 

For the reasons described above, this AD 

requires repetitive inspections of the elevator 

trim tab arm to detect cracks and, if detected, 

replacement of the part with a serviceable 

part. 

This AD also provides an optional 

terminating action for the repetitive 

inspections. 

The Model G115EG airplane is the 

only airplane type-certificated in the 

United States with the same part 

numbers and similar configuration as 

the airplane model described in the 

MCAI. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 2910, January 15, 2013) 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 (78 FR 2910, 

January 15, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 2910, 

January 15, 2013). 

Costs of Compliance 

We estimate that this AD will affect 0 

products of U.S. registry. We also 

estimate that it would take about 3 

work-hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $372 

per product. 

Based on these figures, we estimate 

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

be $627 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. 


TKELLEY on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 75 / Thursday, April 18, 2013 / Rules and Regulations 23113 

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; 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 adding 

the following new AD: 

2013–08–04 Grob-Werke: Amendment 39– 

17421; Docket No. FAA–2013–0013; 

Directorate Identifier 2012–CE–046–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective May 23, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to GROB–WERKE G115EG 

airplanes, all serial numbers, certificated in 

any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 55: Stabilizers. 

(e) Reason 

This AD was prompted by the discovery of 

cracks in the elevator trim tab arms on 

several Grob G 115 airplanes, which could 

result in failure of the part and consequent 

loss of control. The Model G115EG airplane 

is the only airplane type-certificated in the 

United States with the same part numbers 

and similar configuration as the airplane 

model described in the MCAI. We are issuing 

this proposed AD to detect cracks and 

prevent the part from failing. 

(f) Actions and Compliance 

Unless already done, do the following 

actions following Grob Aircraft Service 

Bulletin No. MSB1078–186/3, dated August 

3, 2012. 

(1) Within the next 50 hours time-inservice (TIS) after May 23, 2013 (the effective 

date of this AD) and repetitively thereafter at 

intervals not to exceed 200 hours TIS, inspect 

both left hand (L/H) and right hand (R/H) 

elevator trim tab arms, part number (P/N) 

115E–3758, using a nondestructive testing 

(NDT) method such as a dye-penetrant or 

eddy-current that is beyond just a visual 

inspection. 

(2) If during any inspection required in 

paragraph (f)(1) of this AD a crack is found, 

before further flight, replace the affected 

elevator trim tab arm with P/N 115E–3758/ 

1. The replacement of an elevator trim tab 

arm with P/N 115E–3758/1 will terminate the 

repetitive inspection requirement for that 

trim tab arm. Replacement of both R/H and 

L/H trim tab arms with P/N 115E–3758/1 will 

terminate the repetitive requirement in 

paragraph (f)(1) of this AD. 

(3) Replacement at any time of an elevator 

trim tab arm with P/N 115E–3758/1 will 

terminate the repetitive requirement in 

paragraph (f)(1) of this AD for that elevator 

trim tab arm. Replacement of both R/H and 

L/H trim tab arms with P/N 115E–3758/1 will 

terminate the repetitive requirement in 

paragraph (f)(1) of this AD. 

(g) Credit for Actions Accomplished in 

Accordance With Previous Service 

Information 

This AD provides credit for the actions 

required in this AD if already done before the 

effective date of this AD following Grob 

Aircraft Service Bulletin No. MSB1078–186/ 

2, dated March 28, 2012; Grob Aircraft 

Service Bulletin No. MSB1078–186/1, dated

SUPPLEMENTARY INFORMATION:

Discussion 

On October 22, 2012, at 77 FR 64439, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 to include an AD that would apply 

to Bell Model 430 helicopters. That 

NPRM proposed to require replacing 

certain components of the air data 

system. The proposed requirements 

were intended to correct the published 

Vne and to correct the indicated 

airspeed. 

The Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD No. 

CF–2005–30, dated August 3, 2005, to 

correct an unsafe condition for the Bell 

Model 430 helicopters. Discrepancies in 

the processing and display of air data 

were revealed when testing at low 

temperatures to minus 40 degrees 

Centigrade (¥40°C). The TCCA advises 

that modification to the instrumentation 

is required to reflect the Vne airspeed 

values tested at temperatures to ¥40°C. 

The TCCA states ‘‘This modification 

affects the software in the Vne 

Overspeed Warning computer (required 

for Category A operations) and in the 

AFCS [Automatic Flight Control 

System] Air Data Computer.’’ TCAA 

issued AD CF–2005–30 to require the 

procedures in Bell Alert Service 

Bulletin (ASB) No. 430–05–35, dated 

June 21, 2005, for replacing the affected 

instruments. Bell also issued ASB No. 

430–01–22, dated April 30, 2001 (ASB 

430–01–22), which provided a 

temporary Rotorcraft Flight Manual 

Supplement and placards with 

information on airspeed corrections. 

TCCA did not issue an AD to mandate 

the provisions of ASB 430–01–22. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we did not receive any comments on the 

NPRM (77 FR 64439, October 22, 2012). 

FAA’s Determination 

These helicopters have been approved 

by the TCCA and are approved for 

operation in the United States. Pursuant 

to our bilateral agreement with Canada, 

TCCA has notified us of the unsafe 

condition described in the Canadian 

AD. 

We are issuing this AD because we 

evaluated all information provided by 

TCCA and determined the unsafe 

condition exists and is likely to exist or 

develop on other helicopters of the same 

type designs and that air safety and the 

public interest require adopting the AD 

requirements as proposed. 

Differences Between This AD and the 

TCCA AD 

We do not use the compliance date of 

July 31, 2007. 

Costs of Compliance 

We estimate that this AD will affect 

52 helicopters of U.S. registry. We 

estimate that operators may incur the 

following costs in order to comply with 

this AD: 

• $680 to replace the overspeed 

warning computer, pilot and copilot 

airspeed indicators, Vne converter, and 

AFCS air data computer adapter module 

for each helicopter, assuming 8 work 

hours for each helicopter at an average 

labor rate of $85 per work hour, and 

• $46,074 per helicopter for the 

required parts.
