Airworthiness Directives; Diamond 

Aircraft Industries Powered Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Diamond Aircraft Industries Model H– 

36 ‘‘DIMONA’’ powered sailplanes. 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 report has been received of a failed air 

brake control system torsion tube on a 

Diamond (formerly Hoffman) H 36 powered 

sailplane. The results of the subsequent 

investigation show that the failure was due 

to corrosion damage. 

This condition, if not detected and 

corrected, may lead to failure of the air brake 

control system in flight, resulting in reduced 

control of the aeroplane. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD is effective November 

23, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 23, 2011.

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 August 8, 2011 (76 FR 

48047). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A report has been received of a failed air 

brake control system torsion tube on a 

Diamond (formerly Hoffman) H 36 powered 

sailplane. The results of the subsequent 

investigation show that the failure was due 

to corrosion damage. 

This condition, if not detected and 

corrected, may lead to failure of the air brake 

control system in flight, resulting in reduced 

control of the aeroplane. 

To address this unsafe condition, Diamond 

published Mandatory Service Bulletin (MSB) 

36–105, containing instructions to test and 

inspect the air brake control system torsion 

tube for corrosion damage and, depending on 

findings, the application of anticorrosive 

agent to the inside of the torsion tube, or 

replacement of the torsion tube with a 

serviceable part. 

For the reasons described above, this new 

AD requires repetitive tests and inspections 

of the air brake control system torsion tube 

and applicable corrective actions, depending 

on findings. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (76 

FR 48047, August 8, 2011) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 9 

products of U.S. registry. We also 

estimate that it will take about 4.5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will about $172 per 

product. 

Based on these figures, we estimate 

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

be $4,990.50, or $554.50 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 5 work-hours and require parts 

costing $275, for a cost of $700 per 


sroberts on DSK5SPTVN1PROD with RULES
64794 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Rules and Regulations 

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 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 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

(3) 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

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 (76 FR 

48047, August 8, 2011), 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.

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–21–16 Diamond Aircraft Industries: 

Amendment 39–16839; Docket No. FAA– 

2011–0811; Directorate Identifier 2011– 

CE–026–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective November 23, 2011. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Diamond Aircraft

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

April 25, 2011 (76 FR 22830). That 

supplemental NPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

Cracks have been found on seats [with] 

backrest links P/N (part number) 90–000200– 

104–1 and 90–000200–104–2. These cracks 

can significantly affect the structural integrity 

of seat backrests. 

Failure of the backrest links could result 

in injury to an occupant during 

emergency landing conditions. The 

required actions include a general visual 

inspection for cracking of backrest links; 

replacement with new, improved links 

if cracking is found; and eventual 

replacement of all links with new, 

improved links. You may obtain further
