14 CFR Part 39

[Docket No. FAA-2005-22074; Directorate Identifier 2005-NM-152-AD; 
Amendment 39-14220; AD 2005-16-14]
RIN 2120-AA64


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.

    We have reviewed the service information specified in the table

                               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:
    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

[[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.
