Amendment 39-15174; AD 2007-17-16]

Airworthiness Directives; Gulfstream Aerospace LP Model Galaxy
Airplanes and Model Gulfstream 200 Airplanes
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) 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:
During the manufacturing process of the Poppet Covers of the
Pressurization Safety Valves, burrs that could damage the Valve
Diaphragms were not removed. The damage may eventually cause faulty
operation of the relief valves resulting in an unsafe condition when
combined with additional failures. The serial numbers of the
defective valves and the affected aircraft were identified.
The unsafe condition is damage and subsequent failure of the safety
relief valves, which could result in rapid decompression of the
airplane. We are issuing this AD to require actions to correct the
unsafe condition on these products.
DATES: This AD becomes effective October 2, 2007.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 2,
2007.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a 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 June 6, 2007 (72 FR
31204). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
During the manufacturing process of the Poppet Covers of the
Pressurization Safety Valves, burrs that could damage the Valve
Diaphragms were not removed. The damage may eventually cause faulty
operation of the relief valves resulting in an unsafe condition when
combined with additional failures. The serial numbers of the
defective valves and the affected aircraft were identified.
The unsafe condition is damage and subsequent failure of the safety
relief valves, which could result in rapid decompression of the
airplane. The corrective action includes replacing the pressurization
safety valve, part number 103842-3. You may obtain further information
by examining the MCAI in the AD docket.
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 our 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 affects
about 7 products of U.S. registry. We also estimate that it takes about
10 work-hours per product to comply with the basic requirements of this
AD. The
[[Page 49171]]
average labor rate is $80 per work-hour. Required parts cost about $0
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 costs. 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 AD on U.S.
operators to be $5,600, or $800 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 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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://dms.dot.gov
; or in person at the Docket Operations office 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
Operations office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

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.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-17-16 Gulfstream Aerospace LP (Formerly Israel Aircraft
Industries, Ltd.): Amendment 39-15174. Docket No. FAA-2007-28353;
Directorate Identifier 2007-NM-065-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective October
2, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Gulfstream Model Galaxy airplanes and
Model Gulfstream 200 airplanes, serial numbers 101 through 104, 109,
110, and 118, certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 21: Air
Conditioning.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During the manufacturing process of the Poppet Covers of the
Pressurization Safety Valves, burrs that could damage the Valve
Diaphragms were not removed. The damage may eventually cause faulty
operation of the relief valves resulting in an unsafe condition when
combined with additional failures. The serial numbers of the
defective valves and the affected aircraft were identified.
The unsafe condition is damage and subsequent failure of the safety
relief valves, which could result in rapid decompression of the
airplane. The corrective action includes replacing the
pressurization safety valve, part number 103842-3.
Actions and Compliance
(f) Unless already done, do the following actions. Within 500
flight hours or 12 months after the effective date of this AD,
whichever occurs first: Replace the pressurization safety valve,
part number 103842-3, according to Gulfstream Service Bulletin 200-
21-308, dated February 23, 2007.
FAA AD Differences
Note: This AD differs from the MCAI and/ or service information
as follows: No differences.
