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 the 

products listed above. 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: 

During a maintenance inspection, cracks 

were found on the centre section of fuselage 

frame 19. The investigation on the root cause 

is still in progress. Fuselage frame 19 

supports the rear side of the main landing 

gear (MLG). This condition, if not corrected, 

could cause collapse of frame 19, leading to 

subsequent collapse of a MLG. 

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 April 16, 2007. 

ADDRESSES: You may send comments by 

any of the following methods: 

• DOT Docket Web Site: Go to

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. This streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This proposed AD references the 

MCAI and related service information 

that we considered in forming the 

engineering basis to correct the unsafe 

condition. The proposed AD contains 

text copied from the MCAI and for this 

reason might not follow our plain 

language principles. 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–27295; Directorate Identifier 

2007–CE–013–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal 

information you provide. We will also 

post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No: 

2007–0028, dated February 5, 2007 

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

correct an unsafe condition for the 

specified products. The MCAI states: 

During a maintenance inspection, cracks 

were found on the centre section of fuselage 

frame 19. The investigation on the root cause 

is still in progress. Fuselage frame 19 

supports the rear side of the main landing 

gear (MLG). This condition, if not corrected, 

could cause collapse of frame 19, leading to 

subsequent collapse of a MLG. 

The MCAI requires: 

Since an unsafe condition has been 

identified that may exist or develop on other 

aircraft of the type design, this Airworthiness 

Directive (AD) requires a visual inspection of 

the affected fuselage frame and, if 

discrepancies are found, reporting the results 

to the TC holder. This is considered to be an 

interim action. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

DORNIER LUFTFAHRT GmbH has 

issued Dornier 228 RUAG Alert Service 

Bulletin No. ASB–228–266, dated 

December 1, 2006. 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 


erjones on PRODPC74 with PROPOSALS
Federal Register / Vol. 72, No. 51 / Friday, March 16, 2007 / Proposed Rules 12575 

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 

Based on the service information, we 

estimate that this proposed AD would 

affect about 19 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $9,120, or $480 per 

product. 

In addition, this proposed AD may 

require follow-on actions. We have no 

way of determining the cost of those 

follow-on actions or 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, 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. The FAA amends § 39.13 by adding 

the following new AD: 

DORNIER LUFTFAHRT GmbH: Docket No. 

FAA–2007–27295; Directorate Identifier 

2007–CE–013–AD. 

Comments Due Date 

(a) We must receive comments by April 16, 

2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dornier 228–100, 

Dornier 228–101, Dornier 228–200, Dornier 

228–201, Dornier 228–202, and Dornier 228–

212 airplanes, all serial numbers, certificated 

in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 53: Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During a maintenance inspection, cracks 

were found on the centre section of fuselage 

frame 19. The investigation on the root cause 

is still in progress. Fuselage frame 19 

supports the rear side of the main landing 

gear (MLG). This condition, if not corrected, 

could cause collapse of frame 19, leading to 

subsequent collapse of a MLG. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) For all airplanes, within 25 hours timein-service (TIS) after the effective date of this 

AD, visually inspect the affected fuselage 

frame 19 using the instructions in Dornier 

228 RUAG Alert Service Bulletin No. ASB–

228–266, dated December 1, 2006. 

(2) If any crack is found during the 

inspection required in paragraph (f)(1) of this 

AD, before further flight, contact RUAG 

Aerospace Services GmbH, Dornier 228 

Customer Support, P.O. Box 1253, 82231 

Wessling, Germany; telephone: +49–(0)8153–

30–2280; fax: +49–(0)8153–30–3030; e-mail: 

customersupport.dornier228@ruag.com for 

FAA-approved repair instructions and 

incorporate the repair on the airplane. 

Note 1: This is considered interim action. 

The State of Design and DORNIER 

LUFTFAHRT GmbH are looking at a possible 

repetitive inspection program and/or 

modification program to address this 

condition for the long-term. In the meantime, 

the FAA recommends that you incorporate 

the above inspection into your regular 

maintenance program. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

(1) The MCAI requires different 

compliance times for airplanes operated in 

different conditions. The FAA is not able to 

enforce compliance times based on airplane 

operations since there is no way of 

determining the amount of operations in 

different conditions. To ensure the unsafe 

condition is addressed adequately and 

timely, we are requiring the inspection for all 

airplanes at 25 hours TIS. 

(2) The MCAI allows flight with known 

cracks provided they do not exceed a certain 

limit. FAA policy does not allow flight with 

cracks in primary structure. Since the 

fuselage is considered primary structure, we 

are mandating repair before further flight 

after any crack is found. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. 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 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et.seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency Airworthiness Directive 

2006–0053–E, dated February 22, 2006 

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

correct an unsafe condition for the 

specified products. The MCAI states: 

It has been revealed that the control surface 

balancing procedure in the web and CD/DVD 

versions of the SAAB 2000 SRM (structural 

repair manual) Chapter 51–60–00, Control 

Surface Balancing Procedure is incorrect. The 

incorrect Calculation formula (pages 1, 4 and 

7) was incorporated in Revision 21 of the 

SRM dated April 01/05 and was distributed 

in 4 July 2005 on the CD/DVD issue Apr. 01/ 

05. 

In the incorrect formula, an ‘‘x’’

(multiplication) has been replaced with a ‘‘+’’

(addition) when the data was converted in 

the system and if this formula is followed, 

you may receive a result outside of the 

allowed tolerance. 

Incorrect balance, outside the tolerance of 

the aileron control surface, may lead to 

vibrations that in [the] worst case can result 

in flutter. 

The hard copy of the manual, SAAB 2000 

SRM, is correct.
