Airworthiness Directives; Diamond 

Aircraft Industries Powered Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Diamond Aircraft Industries Model H– 

36 ‘‘DIMONA’’ powered sailplanes. This 

proposed AD results from 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 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. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by September 22, 

2011. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2011– 

0110, dated June 16, 2011 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 


emcdonald on DSK2BSOYB1PROD with PROPOSALS
48048 Federal Register / Vol. 76, No. 152 / Monday, August 8, 2011 / Proposed Rules 

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. 

Relevant Service Information 

Diamond Aircraft Industries GmbH 

has issued Service Bulletin No. MSB 

36–105/1, dated May 2, 2011, and Work 

Instruction WI–MSB 36–105, dated 

April 21, 2011. The actions described in 

this service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of the 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. 

Differences Between This Proposed 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 proposed 

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 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 9 products of U.S. registry. 

We also estimate that it would take 

about 4.5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $172 per 

product. 

Based on these figures, we estimate 

the cost of the proposed 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 would take 

about 5 work-hours and require parts 

costing $275, for a cost of $700 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); 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 proposed AD and placed it in the 

AD docket.

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. The FAA amends § 39.13 by adding 

the following new AD: 

Diamond Aircraft Industries: Docket No. 

FAA–2011–0811; Directorate Identifier 

2011–CE–026–AD. 

Comments Due Date 

(a) We must receive comments by 

September 22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Diamond Aircraft 

Industries Model H–36 ‘‘DIMONA’’ powered 

sailplanes, all serial numbers, certificated in 

any category. 

Subject 

(d) Air Transport Association of America

Reason 

(e) The mandatory continuing 

airworthiness information (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

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to Model L–1011–385–1, L– 

1011–385–1–14, and L–1011–385–1–15 

airplanes. The existing AD currently 

requires implementation of a 

Supplemental Inspection Document 

(SID) program of structural inspections 

to detect fatigue cracking, and repair, if 

necessary, to ensure continued 

airworthiness of these airplanes as they 

approach the manufacturer’s original 

fatigue design life goal. Since we issued 

that AD, an evaluation by the 

manufacturer of usage and flight data 

provided additional information about 

certain Structurally Significant Details 

(SSDs) where fatigue damage is likely to 

occur. This proposed AD would add 

airplanes to the applicability, change 

certain inspection thresholds, add three 

new SSDs, and remove an SSD that has 

been addressed by a different AD. We 

are proposing this AD to prevent fatigue 

cracking that could compromise the 

structural integrity of these airplanes. 

DATES: We must receive comments on 

this proposed AD by September 22, 

2011. 

ADDRESSES: You may send comments by 

any of the following methods:
