### 54145 Federal Register / Vol. 76, No. 169 / Wednesday, August 31, 2011 / Proposed Rules

76 standard 2nd stage Turbine NGVs (i.e., with flexible hub).

This non compliance would increase hot gas ingestion and generate an increase of temperature in the Gas Generator (GG) turbine rotor, potentially resulting in turbine damage and an uncommanded in-flight shutdown. On a single-engine helicopter, this could ultimately lead to an emergency autorotation landing.

We are issuing this AD to prevent overtemperature damage of the gas generator turbine, which could result in an uncommanded in-flight engine shutdown, and a subsequent forced autorotation landing or accident. Compliance (e) Comply with this AD within the compliance times specified, unless already done.
Daily Checks

(f) Starting from the effective date of this AD, perform a daily check (after last flight of the day) for:

(1) Normal rundown time of the gas generator rotor; and

(2) The free rotation of the gas generator rotor; and

(3) No grinding noise during the rundown check, and during the free rotation check of the gas generator rotor.

(g) Guidance on performing the daily checks can be found in the Maintenance Manual, task 71–02–09–760–801 and task

05–20–01–200–801.

(h) If the engine fails any of these daily checks, remove the engine from service before further flight.
Inspection of Repaired 2nd Stage Turbine NGVs

(i) Inspect the 2nd stage turbine NGV for a non-conforming hole configuration, at the compliance times in Table 1 of this AD.Guidance on 2nd stage turbine NGV nonconforming hole configuration can be found in Turbomeca MSB No. A292 72 0829, Version B, dated December 13, 2010.

(o) After the effective date of this AD, do not install an M03 module that has incorporated TU 76 but not incorporated TU 148, unless the module is in compliance with the requirements of this AD.

FAA AD Differences

(p) This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) and/or service information as follows:

(1) This AD does not require sending data to Turbomeca to confirm whether Turbomeca MSB No. A292 72 0829, Version B, dated December 13, 2010, is applicable to the operator’s engine; the MCAI does.

(2) This AD does not incorporate by reference (IBR) Turbomeca MSB No. A292 72 0829, Version B, dated December 13, 2010; the MCAI does.

(3) This AD requires replacing nonconforming 2nd stage turbine NGVs and 1st stage and 2nd stage turbine discs that were operated with non-conforming 2nd stage turbine NGVs but does not require replacing affected M03 modules. The MCAI requires replacing affected M03 modules with M03 modules eligible for installation.

Definition

(q) For the purpose of this AD, a conforming repaired 2nd stage turbine NGV is one with cooling holes in the forward inner flange, and with no cooling holes in the rear flange.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009–0196, dated September 4, 2009 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Several runway excursion incidents and a single accident have occurred in the past with Dornier 328–100 aeroplanes, where the power lever could not be operated as intended during the landing roll-out. * * *

Recurrence of such an event under similar conditions, if not corrected, could result in further cases of runway excursion, possibly resulting in damage to the aeroplane and injury to the occupants.

A modification to the power lever control box has been designed to prevent further power lever handling difficulties.

For the reasons described above, this [EASA] AD requires a modification of the power lever control box as a retrofit for the entire fleet of 328–100 aeroplanes.

The required actions also include revising the airplane flight manual (AFM) to include Dornier 328–100 Temporary Revisions (TR) 04–078, 04– 079, and 04–080, all dated March 15, 2010, to the Abnormal Procedures section of the 328 Support Services 328–100 AFM; and Dornier 328–100 TRs 05–064, 05–065, and 05–066, all dated February 13, 2009, to the Normal Procedures section of the 328 Support Services 328–100 AFM; to introduce modification of the engine control box assembly. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

328 Support Services GmbH has issued Service Bulletin SB–328–76–486, Revision 3, dated April 7, 2010; and Dornier 328–100 TRs 04–078, 04–079, and 04–080, all dated March 15, 2010, to the Abnormal Procedures section of the 328 Support Services 328–100 AFM; and Dornier 328–100 TRs 05–064, 05– 065, and 05–066, all dated February 13, 2009, to the Normal Procedures section of the 328 Support Services 328–100 AFM. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

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 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.


### 54147 Federal Register / Vol. 76, No. 169 / Wednesday, August 31, 2011 / Proposed Rules

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 20 products of U.S. registry. We also estimate that it would take about 79 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 $35,700 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $848,300, or $42,415 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 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

to that in the TRs specified in table 1 of this AD, and these TRs may be removed.

FAA AD Differences

Note 2: This AD differs from the MCAI and/or service information as follows:

(1) Although the MCAI tells you to do an inspection for discrepancies, 328 Support Services Service Bulletin SB–328–76–486, Revision 3, dated April 7, 2010, does not include this action. The off-wing inspection included in the MCAI is not required to address the unsafe condition. The modification addresses the identified unsafe condition. Therefore, this AD does not include that requirement.

(2) Although the MCAI and service information do not include revising the AFM, this AD includes that requirement. The TRsspecified in table 1 of this AD introduce preflight operational tests of the warning system modification, along with abnormal procedures that provide guidance to the flightcrew in the event of various potential warning system faults. These procedures must be adopted at the same time the modification is installed to ensure proper use and operation of the power lever warning system. This has been coordinated with EASA.

Other FAA AD Provisions

(j) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the International Branch, send it to ATTN: Tom Groves, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057– 3356; telephone (425) 227–1503; fax (425) 227–1149. Information may be e-mailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/ certificate holding district office. The AMOC approval letter must specifically reference this AD.

(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.
