# AGENCY:

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

# ACTION:

Final rule; request for comments. 

# SUMMARY:

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

Avionics and electrical wire harnesses are routed behind the Primary Flight Displays (PFD) tray at the rear of the instrument panel. In some cases, the wire harness has been found to be chafing on the PFD tray. That could result in electrical arcing and shorting and subsequent loss of systems essential for safe flight.

This AD requires actions that are intended to address the unsafe condition described in the MCAI. 

# DATES:

This AD becomes effective April 20, 2007. 

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of April 20, 2007. 

We must receive comments on this AD by May 7, 2007.

# 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 AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. 

## Discussion 

The Civil Aviation Authority of Israel (CAAI), which is the aviation authority for Israel, has issued Israeli Airworthiness Directive 31-07-01-12, dated February 15, 2007 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states: 

Avionics and electrical wire harnesses are routed behind the Primary Flight Displays (PFD) tray at the rear of the instrument panel. In some cases, the wire harness has been found to be chafing on the PFD tray. That could result in electrical arcing and shorting and subsequent loss of systems essential for safe flight. 

                    The corrective actions include inspecting the wiring harness for chafing, performing repairs if required; and inspecting the wire harnesses for                           ( print page 16700)                        proper clearance, and rerouting/relocating wire harnesses to obtain proper clearance if required. You may obtain further information by examining the MCAI in the AD docket.                 

## Relevant Service Information 

Gulfstream has issued Service Bulletin 200-31-301, dated January 19, 2007. 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 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. 

## Differences Between the 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. 

## FAA's Determination of the Effective Date 

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because avionics and electrical wire harnesses are routed behind the primary flight displays (PFD) tray at the rear of the instrument panel. In some cases, the wire harness has been found to be chafing on the PFD tray. That could result in electrical arcing and shorting and subsequent loss of systems essential for safe flight. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. 

## Comments Invited 

                    This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the                     **ADDRESSES**                     section. Include “Docket No. FAA-2007-27757; Directorate Identifier 2007-NM-030-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this 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 AD.                 

## 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 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 AD and placed it in the AD docket.
