PROPOSED AD	SOCATA: Docket No. FAA-2010-0286; Directorate Identifier 2010-CE-013-AD.

COMMENTS DUE DATE

(a) We must receive comments by May 3, 2010.

AFFECTED ADS

(b) None.

APPLICABILITY

(c) This AD applies to Model TBM 700 airplanes, all serial numbers  (SNs),
    that:

(1) Are certificated in any category; and

(2) Are equipped  with part number  (P/N) 863520-00 portable  fire exting-
    uishers,  serial  numbers  (S/N)  as  listed  in  L'Hotellier  Service
    Bulletin 863520-26-001, dated December 21, 2009.

SUBJECT

(d) Air Transport Association of America (ATA) Code 26: Fire Protection.

REASON

(e) The mandatory continuing airworthiness information (MCAI) states:

The Civil Aviation Authority of the United Kingdom (UK) has informed  EASA
that significant quantities  of Halon 1211  gas, determined to  be outside
the required specification,  have been supplied  to the aviation  industry
for  use in  fire extinguishing  equipment. Halon  1211 (BCF)  is used  in
portable  fire  extinguishers,  usually  fitted  or  stowed  in   aircraft
passenger cabins and flight decks.

EASA published  Safety Information  Bulletin (SIB)  2009-39 on  23 October
2009 to make the aviation community aware of this safety concern.

The  results  of  the  ongoing  investigation  have  now  established that
LyonTech  Engineering  Ltd,  a  UK-based  company,  has  supplied  further
consignments  of Halon  1211 (BCF)  to L'Hotellier  that do  not meet  the
required specification. This Halon 1211 has subsequently been used to fill
certain P/N 863520-00 portable fire  extinguishers that are now likely  to
be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide
reduced fire suppression, endangering the safety of the aeroplane and  its
occupants. In  addition, extinguisher  activation may  lead to  release of
toxic fumes, possibly causing injury to aeroplane occupants.

For the reason described above,  this EASA AD requires the  identification
and removal  from service  of certain  batches of  fire extinguishers  and
replacement with serviceable units.

ACTIONS AND COMPLIANCE

(f) Unless already done, within 3 months after the effective date of  this
    AD,  do the  following in  accordance with  DAHER-SOCATA TBM  Aircraft
    Service Bulletin SB 70-183, dated January 2010:

(1) Inspect  the fire  extinguisher(s) installed  or carried  on board the
    airplane for any P/N and  S/N fire extinguisher listed in  L'Hotellier
    Service Bulletin 863520-26-001, dated December 21, 2009; and

(2) If, as a result of the inspection required by paragraph (f)(1) of this
    AD,  you  find any  fire  extinguisher listed  in  L'Hotellier Service
    Bulletin  863520-26-001,  dated  December  21,  2009,  before  further
    flight, remove it from the airplane and replace it with a  serviceable
    unit in  accordance with  L'Hotellier Service  Bulletin 863520-26-001,
    dated December 21, 2009.

(3) As of the effective date of this AD, do  not install  any fire exting-
    uisher  listed in  L'Hotellier Service  Bulletin 863520-26-001,  dated
    December 21, 2009, on any airplane, unless it has been overhauled with
    compliant Halon 1211 (BCF)  and re-identified, in accordance  with the
    instructions  of  L'Hotellier  Service  Bulletin  863520-26-001, dated
    December 21, 2009.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose  to adopt a  new airworthiness directive  (AD) for the
products listed above. 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:

The Civil Aviation Authority of the United Kingdom (UK) has informed  EASA
that significant quantities  of Halon 1211  gas, determined to  be outside
the required specification,  have been supplied  to the aviation  industry
for  use in  fire extinguishing  equipment. Halon  1211 (BCF)  is used  in
portable  fire  extinguishers,  usually  fitted  or  stowed  in   aircraft
passenger cabins and flight decks.

EASA published  Safety Information  Bulletin (SIB)  2009-39 on  23 October
2009 to make the aviation community aware of this safety concern.

The  results  of  the  ongoing  investigation  have  now  established that
LyonTech  Engineering  Ltd,  a  UK-based  company,  has  supplied  further
consignments  of Halon  1211 (BCF)  to L'Hotellier  that do  not meet  the
required specification. This Halon 1211 has subsequently been used to fill
certain P/N 863520-00 portable fire  extinguishers that are now likely  to
be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide
reduced fire suppression, endangering the safety of the aeroplane and  its
occupants. In  addition, extinguisher  activation may  lead to  release of
toxic fumes, possibly causing injury to aeroplane occupants.

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

DISCUSSION

The European Aviation Safety Agency  (EASA), which is the Technical  Agent
for the Member States of the  European Community, has issued EASA AD  No.:
2010-0012, dated February 5, 2010 (referred to after this as "the  MCAI"),
to  correct  an unsafe  condition  for the  specified  products. The  MCAI
states:

The Civil Aviation Authority of the United Kingdom (UK) has informed  EASA
that significant quantities  of Halon 1211  gas, determined to  be outside
the required specification,  have been supplied  to the aviation  industry
for  use in  fire extinguishing  equipment. Halon  1211 (BCF)  is used  in
portable  fire  extinguishers,  usually  fitted  or  stowed  in   aircraft
passenger cabins and flight decks.

EASA published  Safety Information  Bulletin (SIB)  2009-39 on  23 October
2009 to make the aviation community aware of this safety concern.

The  results  of  the  ongoing  investigation  have  now  established that
LyonTech  Engineering  Ltd,  a  UK-based  company,  has  supplied  further
consignments  of Halon  1211 (BCF)  to L'Hotellier  that do  not meet  the
required specification. This Halon 1211 has subsequently been used to fill
certain P/N 863520-00 portable fire  extinguishers that are now likely  to
be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide
reduced fire suppression, endangering the safety of the aeroplane and  its
occupants. In  addition, extinguisher  activation may  lead to  release of
toxic fumes, possibly causing injury to aeroplane occupants.

For the reason described above,  this EASA AD requires the  identification
and removal  from service  of certain  batches of  fire extinguishers  and
replacement with serviceable units.

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

RELEVANT SERVICE INFORMATION

DAHER-SOCATA has  issued TBM  Aircraft Service  Bulletin SB  70-183, dated
January 2010.

L'Hotellier has issued Service Bulletin 863520-26-001, dated December  21,
2009.

The actions described in this service information are intended to  correct
the unsafe condition identified in the MCAI.

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  364 products  of  U.S.
registry.  We also  estimate that  it would  take about  .5 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
$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 proposed AD  on U.S.
operators to be $15,470, or $43 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 Pro-
   cedures (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.
