Airworthiness Directives; Gulfstream Model G-IV, GIV-X, GV, and GV-SP Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Final rule; request for comments.
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Model G-IV and GV series airplanes, and certain GIV-X and GV-SP series airplanes. This AD requires a one-time inspection to determine if a certain floor heater pad system is installed, and deactivation of the subject floor heater pad system if it is installed. This AD results from an incident of short-circuiting of the floor heater pads, in which no circuit breakers tripped in response to the short-circuiting. We are issuing this AD to prevent short-circuiting of the floor heater pad system, which could result in a fire in the airplane cabin.
DATES: Effective Date: August 30, 2005.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of August 30, 2005.
We must receive comments on this AD by October 14, 2005.

SUPPLEMENTARY INFORMATION:
Discussion
We have received a report of an incident in which an Adel Wiggins floor heater pad system short-circuited on a Gulfstream GV-SP series airplane. The short-circuit was discovered after an odor of burning was detected emanating from the floor of the cabin. The short-circuit resulted in localized damage to the floorboard and carpet. No circuit breakers tripped as a result of the short-circuiting. This condition, if not corrected, could result in a fire in the airplane cabin.
The subject Adel Wiggins floor heater pad system may also be installed on all Gulfstream Model G-IV and G-V series airplanes and certain Gulfstream Model GIV-X series airplanes. Therefore, those models may be subject to the unsafe condition revealed on certain Model GV-SP series airplanes.
Relevant Service Information
We have reviewed the service information specified in the table below.

GV-SP (G550)................ Gulfstream G550 June 13, 2005. Alert Customer Bulletin 3.
The customer bulletins specified in the table above describe procedures for deactivating the Adel Wiggins floor heater pad system by capping and stowing all associated electrical wiring at each circuit breaker for the floor heater pads, opening and collaring each associated circuit breaker, and labeling each collared circuit breaker inoperative. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition.
Each customer bulletin specified in the table above refers to Gulfstream Drawing 1159SB50018 as an additional source of service information for deactivating the Adel Wiggins floor heater pad system. This drawing is included as an attachment to each customer bulletin.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or develop on other airplanes of the same type design. Therefore, we are issuing this AD to prevent short-circuiting of the floor heater pad system, which could result in a fire in the airplane cabin. This AD requires inspecting the airplane to determine if an Adel Wiggins floor heater pad system is installed and, if one is installed, accomplishing the actions specified in the service information described previously, except as discussed under ``Differences Between the AD and Service Information.''
We are allowing a special flight permit to be issued to operate the airplane to a location where the requirements of this AD can be accomplished, provided that circuit breakers for the floor heater pad system are pulled and collared.
Differences Between the AD and Service Information
A note under paragraph 1.A., Effectivity, of Gulfstream G-IV Alert Customer Bulletin 33, Gulfstream GV Alert Customer Bulletin 22, Gulfstream G300 Alert Customer Bulletin 33, and Gulfstream G400 Alert Customer Bulletin 33, specifies contacting Gulfstream for assistance if an airplane with the Adel Wiggins floor heater pad system installed is not listed in the effectivity block of the referenced Gulfstream repair drawing. For any airplane that is found to have an Adel Wiggins floor heater pad system installed but that is not listed in the effectivity block of the referenced Gulfstream repair drawing, paragraph (h) of this AD requires deactivating the system in accordance with a method approved by the FAA.
Also, although the Accomplishment Instructions of the referenced customer bulletins describe procedures for reporting compliance with the customer bulletin to Gulfstream, this AD does not require that action.
These differences have been coordinated with the manufacturer.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate adoption of this AD, we have found that notice and opportunity for public comment before issuing this AD are impracticable, and that good cause exists to make this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any relevant written data, views, or arguments regarding this AD. Send your comments to an address listed in the ADDRESSES section. Include ``Docket No. FAA-2005- 22074; Directorate Identifier 2005-NM-152-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD that might suggest a need to modify it.
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 with FAA personnel concerning this AD. Using the search function of that web site, anyone can find and read the comments in any of our dockets, including the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477-78), or you may visit http://dms.dot.gov.
Examining the Dockets
You may examine the AD docket on the Internet at http://dms.dot.gov , or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647- 5227) is located on the plaza level of the Nassif Building at the DOT street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after the Docket Management System receives them.
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 have 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 that the regulation:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory
[[Page 47724]]
Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
