DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2010-0862; Directorate Identifier 2010-CE-040-AD]
RIN 2120-AA64

 
Airworthiness Directives; SOCATA Model TBM 700 Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This 
proposed 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 a SOCATA flight test, it was noted some difficulties for 
the pilot to release oxygen. After investigation it was found that, 
due to the design of the oxygen generator release pin, one of the 
mask's lanyard linked to the pin could be jammed when it is pulled 
by a pilot or a passenger.
    This condition, if not corrected, would lead, in case of an 
emergency procedure due to decompression, to a risk of generator 
fault with subsequent lack of oxygen on crew and/or passenger.

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by October 12, 
2010.

Discussion

    On November 6, 2009, we issued AD 2009-23-12, Amendment 39-16086 
(74 FR 58539; November 13, 2009). That AD required actions intended to 
address an unsafe condition on the products listed above. AD 2009-23-12 
revised AD 2009-13-05 (74 FR 29126, June 19, 2009), which was intended 
to address an unsafe condition on the products listed above.
    Since we issued AD 2009-23-12, SOCATA has developed a modification 
that is a terminating action to address the unsafe condition.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2010-0090, dated May 18, 2010 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    During a SOCATA flight test, it was noted some difficulties for 
the pilot to release oxygen. After investigation it was found that, 
due to the design of the oxygen generator release pin, one of the 
mask's lanyard linked to the pin could be jammed when it is pulled 
by a pilot or a passenger.
    This condition, if not corrected, would lead, in case of an 
emergency procedure due to decompression, to a risk of generator 
fault with subsequent lack of oxygen on crew and/or passenger.
    For the reason described above, SOCATA released Pilot Operating 
Handbook (POH) Temporary Revision (TR) 03 which asks, in case of 
failure to release oxygen, to pull on the other mask lanyard in 
order to activate the oxygen generator. The Emergency AD 2009-0096-E 
was issued to mandate the follow-up of these actions by the 
operators in case of failure. This EAD was subsequently revised into 
AD 2009-0096R1 in order to clarify the applicability.
    A SOCATA modification enabling to solve this issue has been 
developed. Consequently, this new AD, superseding EASA AD 2009-
0096R1 retaining its requirements, requires implementing the 
modification which is a terminating action.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    SOCATA has issued SOCATA TBM 700 A & B Pilot's Operating Handbook 
(POH), Temporary Revision No. 3, dated March 2009; and DAHER-SOCATA TBM 
Aircraft Mandatory Service Bulletin SB 70-168, dated December 2009. The 
actions described in this service information are intended to correct 
the unsafe condition identified in the MCAI.

[[Page 52481]]

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 proposed 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 proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 126 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. Required parts would cost 
about $66 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $19,026, or $151 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); 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 proposed AD and placed it in the AD docket.

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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 removing Amendment 39-16086 (74 FR 
58539; November 13, 2009), and adding the following new AD:

SOCATA: Docket No. FAA-2010-0862; Directorate Identifier 2010-CE-
040-AD.

Comments Due Date

    (a) We must receive comments by October 12, 2010.

Affected ADs

    (b) This AD supersedes AD 2009-23-12, Amendment 39-16086.

Applicability

    (c) This AD applies to Model TBM 700 airplanes, serial numbers 1 
through 204, 206 through 239, and 241 through 243, that are:
    (i) Certificated in any category; and
    (ii) equipped with a chemical oxygen generation system.

Subject

    (d) Air Transport Association of America (ATA) Code 35: Oxygen.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    During a SOCATA flight test, it was noted some difficulties for 
the pilot to release oxygen. After investigation it was found that, 
due to the design of the oxygen generator release pin, one of the 
mask's lanyard linked to the pin could be jammed when it is pulled 
by a pilot or a passenger.
    This condition, if not corrected, would lead, in case of an 
emergency procedure due to decompression, to a risk of generator 
fault with subsequent lack of oxygen on crew and/or passenger.
    For the reason described above, SOCATA released Pilot Operating 
Handbook (POH) Temporary Revision (TR) 03 which asks, in case of 
failure to release oxygen, to pull on the other mask lanyard in 
order to activate the oxygen generator. The Emergency AD 2009-0096-E 
was issued to mandate the follow-up of these actions by the 
operators in case of failure. This EAD was subsequently revised into 
AD 2009-0096R1 in order to clarify the applicability.
    A SOCATA modification enabling to solve this issue has been 
developed. Consequently, this new AD, superseding EASA AD 2009-
0096R1 retaining its requirements, requires implementing the 
modification which is a terminating action.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Before further flight after the effective date of this AD, 
insert Page 3.13.5 of Temporary Revision No. 3, dated March 2009, 
into the Emergency Procedures section and the Limitations section of 
SOCATA TBM 700 A & B Pilot's Operating Handbook (POH).
    (2) Within 7 months after the effective date of this AD or 100 
hours time-in-service (TIS) after the effective date of this AD, 
whichever occurs first, replace the existing oxygen generator 
release pin, part number (P/N) T700A3510038100, with an open pin, P/
N T700A351004410000, using the accomplishment instructions of DAHER-
SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-168, dated 
December 2009.
    (3) Upon replacement of the existing oxygen generator release 
pin with an open pin, P/N T700A351004410000, using the 
accomplishment instructions of SB No. 70-168, remove Page 3.13.5 of 
Temporary Revision No. 3, dated March 2009, as inserted by paragraph 
(f)(1) of this AD from the POH.
    (4) After the effective date of this AD, do not install in any 
affected airplane an oxygen generator release pin, P/N 
T700A3510038100.
