          - 14 CFR Part 39
          - [Docket No. FAA-2009-0261 Directorate Identifier 2009-CE-017-AD; Amendment 39-15943; AD 2009-13-04]

# AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

# ACTION:

Final rule.

# SUMMARY:

We are adopting a new airworthiness directive (AD) for the products listed above. 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:

Excessive wear on a guide pin of a power lever has been detected during inspections. The total loss of the pin could cause loss of the flight idle stop and lead to inadvertent activation of the beta mode in flight. The inadvertent activation of beta mode in flight can result in loss of control of the airplane.

We are issuing this AD to require actions to correct the unsafe condition on these products.

# DATES:

This AD becomes effective July 24, 2009.

On July 24, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

# ADDRESSES:

                        You may examine the AD docket on the Internet at                         *http://www.regulations.gov*                         or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590.

# 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 NPRM was published in the                     **Federal Register**                     on April 23, 2009 (74 FR 18477). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:                

Excessive wear on a guide pin of a power lever has been detected during inspections. The total loss of the pin could cause loss of the flight idle stop and lead to inadvertent activation of the beta mode in flight. The inadvertent activation of beta mode in flight can result in loss of control of the airplane.

For the reasons described above, this new EASA Airworthiness Directive (AD) introduces a repetitive detailed inspection of the guide pins of the power and condition levers and requires the replacement of the pins that exceed the allowable wear-limits.
      ( print page 29117)    

## Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM 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

Based on the service information, we estimate that this AD will affect 17 products of U.S. registry. We also estimate that it will take about 20 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $10 per product.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $27,370 or $1,610 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.

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, 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.

## 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 

2. The FAA amends § 39.13 by adding the following new AD: 

**2009-13-04 Dornier Luftfahrt GmbH:**                             Amendment 39-15943; Docket No. FAA-2009-0261; Directorate Identifier 2009-CE-017-AD.                        

## Effective Date

(a) This airworthiness directive (AD) becomes effective July 24, 2009.

## Affected ADs

(b) None.

## Applicability

(c) This AD applies to Models 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 76: Engine Controls.

## Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

Excessive wear on a guide pin of a power lever has been detected during inspections. The total loss of the pin could cause loss of the flight idle stop and lead to inadvertent activation of the beta mode in flight. The inadvertent activation of beta mode in flight can result in loss of control of the airplane.

For the reasons described above, this new EASA Airworthiness Directive (AD) introduces a repetitive detailed inspection of the guide pins of the power and condition levers and requires the replacement of the pins that exceed the allowable wear-limits.

## Actions and Compliance

(f) Do the following actions per the instructions in RUAG Aerospace Defence Technology Dornier 228 Alert Service Bulletin ASB-228-279, dated December 19, 2008:

                            (1)                             *Initial Inspection:*                             Unless already done within the last 1,200 hours time-in-service (TIS) as of July 24, 2009 (the effective date of this AD), inspect upon accumulating 9,600 hours on the guide pins of the power and condition levers or within the next 100 hours TIS after July 24, 2009 (the effective date of this AD), whichever occurs later.                        

                            (2)                             *Repetitive Inspections:*                             Inspect within 1,200 hours since the last inspection required by paragraph (f)(1) of this AD and thereafter at intervals not to exceed 1,200 hours TIS.                        

                            (3)                             *Replacement:*                             Replace the guide pins as follows:                        

(i) Before further flight, after any inspection required in paragraphs (f)(1) or (f)(2) of this AD, where any guide pin exceeds the acceptable wear-limits as defined in the service bulletin; and

(ii) Prior to any required inspection, you may install new power and condition levers guide pins instead of doing the inspections required in this AD. You must then inspect or install new pins upon accumulating 9,600 hours TIS and follow the repetitive inspection intervals of this AD if replacement is not made.

# Note 1:

 If the hours TIS of the throttle box assembly is unknown, you may use the hours TIS of the airplane to determine the compliance time for the inspection.
      ( print page 29118)    

## FAA AD Differences

# Note 2:

 This AD differs from the MCAI and/or service information as follows: No differences.

## Other FAA AD Provisions

(g) 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 ATTN: Greg Davison, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4130; fax: (816) 329-4090. 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.
