AIRWORTHINESS DIRECTIVES; Aero Advantage ADV200 Series (Part
Numbers ADVPL211CC and ADVPL212CW) Vacuum Pumps

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)  for
all airplanes  equipped with  Aero Advantage  ADV200 series  (part numbers
ADVPL211CC and ADVPL212CW) vacuum pumps installed under supplemental  type
certificate number  SA10126SC, through  field approval,  or other methods.
This proposed AD would require you to remove any affected vacuum pump  and
related  monitor  system,  remove the  applicable  airplane  flight manual
supplement (AFMS)  and placard,  and install  an FAA-approved  vacuum pump
other  than  the affected  part  numbers. This  proposed  AD results  from
several reports of pump chamber  failure. We are issuing this  proposed AD
to correct  problems with  the vacuum  pump before  failure or malfunction
during  instrument flight  rules (IFR)  flight that  can lead  to loss  of
flight instruments  critical for  flight. The  loss of  flight instruments
could cause pilot disorientation and loss of control of the aircraft.

DATES: We must receive any comments on this proposed AD by July 11, 2005.

ADDRESSES: Use one  of the following  to submit comments  on this proposed
AD:

http://dms.dot.gov.  The  comments  will be  available  in  the AD  docket
shortly after the DMS receives them.

DISCUSSION

What events have  caused this proposed  AD? For the  Aero Advantage ADV200
series (part numbers (P/Ns)  ADVPL211CC and ADVPL212CW) vacuum  pumps, FAA
has  received  reports of  14  single shaft  failures  and 11  dual  shaft
failures in a population of 285 pumps. Nine of the failures occurred  with
less  than 100  hours time-in-service.  The failures  are concentrated  on
airplanes with the Lycoming Engines IO-540 series engines.

In  May  2004,  Aero  Advantage reported  to  FAA  that  they had  stopped
production  and  sales  of  the pumps  and  that  they  were quitting  the
business.

The  Aero  Advantage  ADV200  series  vacuum  pumps  are  installed  under
supplemental type certificate number SA10126SC, through field approval, or
other methods.  The installation  of the  vacuum pump  includes a  monitor
system, airplane flight manual supplement (AFMS), and a placard.

What is the potential impact if FAA took no action? Failure or malfunction
of the vacuum pump during instrument flight rules (IFR) flight can lead to
loss of flight instruments critical for flight.

The loss of flight instruments  could cause pilot disorientation and  loss
of control of the aircraft.

FAA'S DETERMINATION AND REQUIREMENTS OF THIS PROPOSED AD

What has  FAA decided?  We have  evaluated all  pertinent information  and
identified an unsafe condition that is likely to exist or develop on other
products of this same  type design. For this  reason, we are proposing  AD
action.

What would this proposed AD require? This proposed AD would require you to
remove any Aero Advantage  ADV200 series (P/Ns ADVPL211CC  and ADVPL212CW)
vacuum pump, the related monitor  system, the applicable AFMS and  related
placard installed  under supplemental  type certificate  number SA10126SC,
through field  approval, or  other methods.  It would  also require you to
install an FAA-approved vacuum pump other than the affected part numbers.

How does the revision to 14 CFR  part 39 affect this proposed AD? On  July
10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997,  July
22, 2002),  which governs  FAA's AD  system. This  regulation now includes
material that  relates to  altered products,  special flight  permits, and
alternative methods of compliance.  This material previously was  included
in each individual AD. Since this material is included in 14 CFR part  39,
we will not include it in future AD actions.

COSTS OF COMPLIANCE

How many airplanes  would this proposed  AD impact? We  estimate that this
proposed AD could affect 285 airplanes in the U.S. registry.

What would be the cost impact of this proposed AD on owners/ operators  of
the  affected  airplanes?  We  estimate the  following  costs  to  do this
proposed removal and replacement. We have no way of determining the  exact
number of airplanes that will need this removal and replacement:

    ----------------------------------------------------------------------
                                      AVERAGE PARTS      TOTAL COST PER
                LABOR COST                 COST             AIRPLANE
    ----------------------------------------------------------------------
    3 work hours x $65 = $195.......       $400               $595
    ----------------------------------------------------------------------

AUTHORITY FOR THIS RULEMAKING

What authority does FAA have for issuing this rulemaking action? 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 AD.

REGULATORY FINDINGS

Would this proposed  AD impact various  entities? We have  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.

Would this proposed  AD involve a  significant rule or  regulatory action?
For the reasons discussed above, I certify that this proposed 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 summary  of the costs to  comply with this proposed  AD (and
other information as included in the Regulatory Evaluation) and placed  it
in the AD Docket. You may get a copy of this summary by sending a  request
to us at the address  listed under ADDRESSES. Include "AD  Docket FAA-2005
-20440; Directorate Identifier 2005-CE-05-AD" in your request.

LIST OF SUBJECTS IN 14 CFR PART 39

Air transportation, Aircraft, Aviation safety, Safety.

THE PROPOSED AMENDMENT

Accordingly, under the authority delegated to me by the Administrator, the
Federal  Aviation  Administration proposes  to  amend 14  CFR  part 39  as
follows:
