Airworthiness Directives; Precise Flight, Inc. Models SVS I and 
SVS IA Standby Vacuum Systems

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 Precise Flight, Inc. (Precise Flight) 
Models SVS I and SVS IA standby vacuum systems (SVS) installed under 
certain supplemental type certificates or through field approval. This 
proposed AD would require you to replace the airplane flight manual 
supplement (AFMS) in the airplane flight manual with the appropriate 
revision and install placards as defined in the AFMS, upgrade the Model 
SVS I or SVS IA SVS to the Model VI SVS, and add the instructions for 
continued airworthiness (ICA) to the maintenance schedule for the 
aircraft. This proposed AD results from several reports of failed 
shuttle control valves of the standby vacuum system (SVS) and one 
report of an airplane crash with a fatality in which improper use of 
the SVS was a factor. We are issuing this proposed AD to correct 
problems with the SVS before failure or malfunction during instrument 
flight rules (IFR) flight that can lead to pilot disorientation and 
loss of control of the aircraft.

DATES: We must receive any comments on this proposed AD by April 29, 
2005.

Discussion

    What events have caused this proposed AD? The FAA has received 
several reports of problems on aircraft equipped with a Precise Flight, 
Inc. standby vacuum system (SVS). In particular, the reports show 14 
incidents of failed shuttle control valves and one report of an 
airplane crash with a fatality where improper use of the SVS was a 
factor that caused us to issue AD 99-24-10, Amendment 39-11434 (64 FR 
66747, November 30, 1999). AD 99-24-10 currently requires the following 
on all aircraft equipped with Precise Flight, Inc. Model SVS III 
standby vacuum systems installed under the applicable supplemental type 
certificate (STC) or through field approval:

--Incorporate revised operating limitations for the affected SVS into 
the airplane flight manual (AFM);
--Inspect (repetitively) the push-pull cable, vacuum lines, saddle 
fittings, and shuttle valve for correct installation and damage (wear, 
chafing, deterioration, and so forth); and
--Correct any discrepancy found and conduct a function test of the 
vacuum system after the inspections.

    The SVS is intended to provide emergency vacuum power for aircraft 
instruments when the primary vacuum system fails. The design of the 
Precise Flight, Inc. Models SVS I and SVS IA SVS is similar to the 
Model SVS III SVS, and so it may not be able to provide sufficient 
vacuum power to correctly measure altitude and operate the vacuum 
instruments. The upgrade of the Models SVS I or IA SVS to the Model SVS 
VI SVS provides sufficient vacuum power to correctly measure altitude 
and operate the vacuum instruments.
    Failure of the SVS in instrument flight rules (IFR) can lead to the 
pilot making incorrect decisions based on the data received from the 
instruments with consequent loss of control of the aircraft.
    The Precise Flight, Inc. Models SVS I and SVS IA SVS are installed 
on aircraft through a supplemental type certificate (STC) or through 
field approval. The Applicability section of the proposed AD lists the 
applicable STCs and aircraft that could have these SVS installed. This 
list is not meant to be exhaustive nor does it include all aircraft 
with the systems installed through field approval.
    What is the potential impact if FAA took no action? Failure or 
malfunction of the SVS during IFR flight can lead to pilot 
disorientation and loss of control of the aircraft.
    Is there service information that applies to this subject? Precise 
Flight, Inc. has issued Installation Report No. 08080, Standby Vacuum 
System Model VI--Shuttle Valve S/N 10243 & Subsequent (Manual Valve), 
Revision A, dated February 21, 2001. This report provides instructions 
for the upgrade of the Models SVS I or SVS IA SVS to the Model VI SVS; 
and includes procedures for upgrading to the Model SVS VI SVS.

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 replace the airplane flight manual supplement (AFMS) in the 
airplane flight manual with the appropriate revision and install 
placards as defined in the AFMS, upgrade the Model SVS I or SVS IA SVS 
to the Model VI SVS, and add the instructions for continued 
airworthiness (ICA) to the maintenance schedule for the aircraft.
    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 affects 800 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 
replace the airplane flight manual supplement (AFMS) in the airplane 
flight manual with the appropriate revision. We have no way of 
determining the number of airplanes that may need this replacement:

------------------------------------------------------------------------
                                                         Total cost  per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
1 work hour x $65 = $65...............            None              $65
------------------------------------------------------------------------

    We estimate the following costs to do any upgrade to the Model SVS 
VI SVS, install placards, and add the installation report including the 
instructions for continued airworthiness (ICA) to the maintenance 
schedule for the aircraft. We have no way of determining the number of 
airplanes that may need this upgrade:

[[Page 10519]]



------------------------------------------------------------------------
                                                         Total cost  per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
3 work hour x $65 = $195..............             $77             $272
------------------------------------------------------------------------

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 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-2004-19354; Directorate Identifier 2004-CE-30-AD'' in 
your request.
