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.

What Is the Unsafe Condition Presented in This AD?

(d) This AD is the result of several reports of failed shuttle control valves of the SVS and one report of an airplane crash with a fatality in which improper use of the SVS was a factor.
