Amendment 39-15468; AD 2008-06-28 R1]
RIN 2120-AA64
Airworthiness Directives; Avidyne Corporation Primary Flight
Displays (Part Numbers 700-00006-000, -001, -002, -003, and -100)
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) to
revise AD 2008-06-28, which applies to certain Avidyne Corporation
(Avidyne) Primary Flight Displays (PFDs) (Part Numbers (P/Ns) 700-
00006-000, -001, -002, -003, and -100) that are installed on airplanes.
AD 2008-06-28 currently requires you to do a check of the maintenance
records and inspection of the PFD (if necessary) to determine if an
affected serial number PFD is installed. If an affected serial number
PFD is installed, this AD requires you to incorporate information that
limits operation when certain conditions for the PFD or backup
instruments exist. Since we issued AD 2008-06-28, we have learned that
there is an incorrect serial number (SN) listed in AD 2008-06-28.
Consequently, this AD retains the actions of AD 2008-06-28 and corrects
the incorrect serial number. We are issuing this AD to prevent certain
conditions from existing when PFDs display incorrect attitude,
altitude, and airspeed information. This could result in airspeed/
altitude mismanagement or spatial disorientation of the pilot with
consequent loss of airplane control, inadequate traffic separation, or
controlled flight into terrain.
DATES: This AD becomes effective on April 10, 2008 (the effective date
of AD 2008-06-28).
We must receive any comments on this AD by June 13, 2008.

SUPPLEMENTARY INFORMATION:
Discussion
Several field reports of PFDs displaying incorrect altitude and
airspeed information caused us to issue AD 2008-06-28, Amendment 39-
15440 (73 FR 15862, March 26, 2008). AD 2008-06-28 currently requires a
check of the maintenance records and an inspection of the PFD (if
necessary) to determine if an affected serial number PFD is installed.
If an affected serial number PFD is installed, this AD requires you to
incorporate information that limits operation when certain conditions
for the PFD or backup instruments exist.
We received several field reports of PFDs displaying incorrect
altitude and airspeed information. These occurrences included incorrect
display of information at system startup, including one or more of the
following:
Altitude significantly in error when compared to field
elevation with local barometric correction setting entered on PFD.
Altitude significantly in error when compared to backup
altimeter with identical barometric correction settings.
Non-zero airspeed (inconsistent with high winds or
propwash from a nearby airplane) indicated at system startup.
Altitude or airspeed indications that vary noticeably
after startup under static conditions.
Erroneous airspeed indications in combination with
erroneous attitude indications.
A steady or intermittent ``red X'' in place of the
airspeed indicator, altimeter, vertical speed indicator, or attitude
indicator.
The conditions described above occur because of a manufacturing
process defect on a certain batch of PFD serial numbers during
incorporation of a design improvement on the air data unit assembly.
The root cause of this manufacturing process defect is still being
analyzed.
Since we issued AD 2008-06-28, we have learned that PFD SN 0030197
is incorrectly listed in AD 2008-06-28. The correct SN is 20030197.
This condition, if not corrected, could result in airspeed/altitude
mismanagement or spatial disorientation of the pilot and consequent
loss of airplane control, inadequate traffic separation, or controlled
flight into terrain.
FAA's Determination and Requirements of This AD
We are issuing this AD because we evaluated all the information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This AD revises
AD 2008-06-28 by retaining the actions of AD 2008-06-28 and correcting
the incorrect serial number.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this
[[Page 19964]]
AD, we determined that notice and opportunity for public comment before
issuing this AD are impracticable, and that good cause exists for
making this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and an opportunity for
public comment. We invite you to send any written relevant data, views,
or arguments regarding this AD. Send your comments to an address listed
under the ADDRESSES section. Include the docket number ``FAA-2008-0340;
Directorate Identifier 2008-CE-020-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD. We will consider
all comments received by the closing date and may amend the AD in light
of those comments.
We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive concerning this AD.
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 AD will not have federalism implications
under Executive Order 13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the AD, the regulatory
evaluation, any comments received, and other information on the
Internet at http://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

Alternative Methods of Compliance (AMOCs)
(f) The Manager, Boston Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. Send information to
ATTN: Solomon Hecht, Aerospace Engineer, Boston ACO, 12 New England
Executive Park, Burlington, MA 01803; telephone: (781) 238-7159;
fax: (781) 238-7170. Before using any approved AMOC on any airplane
to which the AMOC applies, notify your appropriate principal
inspector (PI) in the FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.

Appendix to AD 2008-06-28 R1 Limitations Regarding Avidyne Primary
Flight Displays (PFDs)
Before conducting flight operations, pilots must review and be
familiar with the Crosscheck Monitor section of the Avidyne Primary
Flight Display Pilot's Guide and all limitations contained in the
airplane flight manual, pilot's operating handbook, or aircraft
operating handbook.
As a normal practice, all pilots should be vigilant in
conducting proper preflight and in-flight checks of instrument
accuracy, including:
Preflight check of the accuracy of both the primary and
backup altimeter against known airfield elevation and against each
other.
Verification of airspeed indications consistent with
prevailing conditions at startup, during taxi, and prior to takeoff.
``Airspeed alive'' check and reasonable indications
during takeoff roll.
Maintenance of current altimeter setting in both
primary and backup altimeters.
Cross-check of primary and backup altimeters at each
change of altimeter setting and prior to entering instrument
meteorological conditions (IMC).
Cross-check of primary and backup altimeters and
validation against other available data, such as glideslope
intercept altitude, prior to conducting any instrument approach.
Periodic cross-checks of primary and backup airspeed
indicators, preferably in combination with altimeter cross-checks.
For flight operations under instrument flight rules (IFR) or in
conditions in which visual reference to the horizon cannot be
reliably maintained (that is IMC, night operations, flight
operations over water, in haze or smoke) and the pilot has reasons
to suspect that any source (PFD or back-up instruments) of attitude,
airspeed, or altitude is not functioning properly, flight under IFR
or in these conditions must not be initiated (when condition is
determined on the
[[Page 19967]]
ground) and further flight under IFR or in these conditions is
prohibited until equipment is serviced and functioning properly.
Operation of aircraft not equipped with operating backup (or
standby) attitude, altimeter, and airspeed indicators that are
located where they are readily visible to the pilot is prohibited.
Pilots must frequently scan and cross-check flight instruments
to make sure the information depicted on the PFD correlates and
agrees with the information depicted on the backup instruments.
