Airworthiness Directives; Gulfstream Aerospace LP (Type 
Certificate Previously Held by Israel Aircraft Industries, Ltd.) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Gulfstream Aerospace LP (Type Certificate Previously Held by Israel 
Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. This 
proposed AD was prompted by a review that determined that the runway 
slope and anti-ice corrections to V1 and take-off distances 
in the Gulfstream G150 Airplane Flight Manual (AFM) were presented in a 
non-conservative manner. This proposed AD would require revising the 
performance section of the AFM to include procedures to advise the 
flightcrew of certain runway slope and anti-ice corrections and take-
off distance values. We are proposing this AD to prevent the use of 
published non-conservative data, which could result in the inability to 
meet the required take-off performance, with consequent hazard to safe 
operation during performance-limited take-off operations.

DATES: We must receive comments on this proposed AD by November 5, 
2012.

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli Airworthiness 
Directive 01-12-02-02, dated March 2, 2012 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    This [Israeli] AD mandates revised limitations in the G150 AFM, 
pertaining to the Performance Section. Each operator must 
incorporate Temporary Rev.3 to the G150 AFM.

The unsafe condition is the use of published non-conservative data, 
which could result in the inability to meet the required take-off 
performance, with consequent hazard to safe operation during 
performance-limited take-off operations. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Gulfstream has issued Gulfstream G150 Temporary Revision 3, dated 
December 14, 2011, to Section V, Performance, of the Gulfstream G150 
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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 56 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $4,760, or $85 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Gulfstream G150 airplanes; certificated in any category; all serial 
numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 01, Operations 
information.

(e) Reason

    This AD was prompted by a review that determined that the runway 
slope and anti-ice corrections to V1 and take-off 
distances in the G150 Airplane Flight Manual (AFM) were presented in 
a non-conservative manner. We are issuing this AD to prevent the use 
of published non-conservative data, which could result in the 
inability to meet the required take-off performance, with consequent 
hazard to safe operation during performance-limited take-off 
operations.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) AFM Revision

    Within 60 days after the effective date of this AD, revise 
Section V, Performance, of the Gulfstream G150 AFM to include the 
information in Gulfstream G150 Temporary Revision 3, dated December 
14, 2011. This TR introduces corrections for runway slope. Operate 
the airplane according to the procedures in the TR.

    Note 1 to paragraph (g) of this AD: This may be done by 
inserting copies of Gulfstream G150 TR Revision 3, dated December 
14, 2011, in the AFM. When this TR has been included in general 
revisions of the AFM, the general revisions may be inserted in the 
AFM, provided the relevant information in the general revision is 
identical to that in Gulfstream G150 TR Revision 3, dated December 
14, 2011, and the TR may be removed.
