ACTION: Notice of proposed rulemaking (NPRM). hsrobinson on PROD1PC76 with PROPOSALS AGENCY: SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008–06– 28 R1, 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 R1 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 and incorporate (if necessary) operational limitations. Since we issued AD 2008– 06–28 R1, Avidyne developed a factory service procedure that will correct the VerDate Aug<31>2005 16:24 Nov 13, 2008 Jkt 217001 problems on these Avidyne PFDs and also factory serviced certain serial number PFDs. Consequently, this proposed AD would retain the actions from AD 2008–06–28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008–06–28 R1. We are proposing 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: We must receive comments on this proposed AD by January 13, 2009.

We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. 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 required the following on Avidyne PFDs (P/Ns 700–00006–000, –001, –002, –003, and –100) that are installed on airplanes: • Checking of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed; and • If an affected serial number PFD is installed, incorporating information that limits operation when certain conditions for the PFD or backup instruments exist. An incorrect serial number (SN) listed in AD 2008–06–28 caused us to issue AD 2008–06–28 R1, Amendment 39– 15468 (73 FR 19963, April 14, 2008). AD 2008–06–28 R1 corrects the incorrect SN and retains the actions of AD–2008– 06–28. Since we issued AD 2008–06–28 R1, Avidyne has prepared a factory service procedure that will correct the possible incorrect altitude and airspeed information displayed on these Avidyne PFDs and received approval for a corresponding alternative method of compliance (AMOC) to modify certain serial number PFDs at the factory, eliminating the unsafe condition in these units. This proposed AD retains the actions from AD 2008–06–28 R1 until the factory servicing is done. This proposed AD would require you to inspect for a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label or a ‘‘MOD 52’’ marking; if the label or mark is not present, do the PFD air data system performance verification test; if the PFD passes the test, remove the operational limitations requirement; or if the PFD does not pass the test, remove the PFD, have the PFD factory serviced, install a PFD that has passed the air data system verification test or has been factory serviced (PFD bears a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label; or a ‘‘MOD 52’’ marking); and E:\FR\FM\14NOP1.SGM 14NOP1 67430 Federal Register / Vol. 73, No. 221 / Friday, November 14, 2008 / Proposed Rules remove the operational limitations requirement. This proposed AD also reduces the serial number applicability from that of AD 2008–06–28 R1 due to Avidyne modifying PFDs at the factory. This condition, if not corrected, 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. Relevant Service Information We have reviewed Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008. The service information describes procedures for: • Identifying possible Avidyne PFDs by serial number; • Identifying PFDs that have already been serviced; • Doing Avidyne PFD air data system performance verification test procedures; and • Having any Avidyne PFD that has not passed the air data system verification test or has not been factory serviced (PFD does not bears a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label; or a ‘‘MOD 52’’ marking) serviced. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 2008–06–28 R1 with a new AD that would retain the actions from AD 2008–06–28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008–06–28 R1. This proposed AD would require you to use the service information described previously to perform these actions. Differences Between This Proposed AD and the Service Information The proposed AD includes terminating action for the requirement of AD 2008–06–28 R1 to incorporate information that limits operation when certain conditions for the PFD or backup instruments exist. The requirements of this proposed AD, if adopted as a final rule, would take precedence over the provisions in the service information. Costs of Compliance We estimate that this proposed AD would affect 384 airplanes in the U.S. registry. We estimate the following costs to do the proposed serial number determination: Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 1 work-hour × $80 per hour = $80 ..................................................................... Not applicable ......................... $80 $30,720 We estimate the following costs to do any necessary test and replacement that would be required based on the results of the proposed test. We have no way of determining the number of airplanes that may need this test and replacement: Labor cost Parts cost Total cost per airplane 4 work-hours × $80 per hour = $320 ..................................................................................... Not applicable ................................. $320 hsrobinson on PROD1PC76 with PROPOSALS Authority for This Rulemaking Regulatory Findings 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. 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. For the reasons discussed above, I certify that the 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 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.

You must follow the actions in the paragraphs below to determine what actions of paragraph (f) apply. Under 14 CFR 43.7, the owner/operator holding at least a private pilot certificate is allowed to do the check in paragraph (d)(1) of this AD. All other actions must be done by a certificated mechanic, unless noted differently. (1) Do a logbook check of aircraft records (previously referred to in AD 2008–06–28 R1 as ‘‘maintenance records’’) to determine if any PFD (P/Ns 700–00006–000, 700–00006– 001, 700–00006–002, 700–00006–003, or 700–00006–100) with any affected serial number listed in Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008, is installed. (i) If, as a result of the logbook check, you positively identify that the PFD installed does not have a serial number affected by this AD, then only paragraph (f)(5) of this AD applies to you. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 67431 (ii) If, as a result of the logbook check, you cannot positively identify the serial number of the PFD, do the visual inspection required in paragraph (d)(2) of this AD. (iii) If, as a result of the logbook check, you find any PFD installed with an affected serial number, do the actions required by paragraph (f) of this AD, including all subparagraphs as applicable. (2) If, as a result of the above logbook check, you cannot positively identify the serial number of the PFD, visually inspect any PFD (P/Ns 700–00006–000, 700–00006– 001, 700–00006–002, 700–00006–003, or 700–00006–100) for any affected serial number listed in Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008. (i) If, as a result of this visual inspection, you positively identify that the PFD installed does not have a serial number affected by this AD, then only paragraph (f)(5) of this AD applies to you. (ii) If, as a result of this visual inspection, you identify that the PDF installed does have a serial number affected by this AD, do the actions required in paragraph (f) of this AD, including all subparagraphs as applicable. Unsafe Condition (e) This AD results from several field reports of Avidyne PFDs displaying incorrect altitude and airspeed information and Avidyne preparing a factory service procedure that will correct the possible incorrect altitude and airspeed information displayed. 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. Compliance (f) To address this problem, you must do the following, unless already done: E:\FR\FM\14NOP1.SGM 14NOP1 67432 Federal Register / Vol. 73, No. 221 / Friday, November 14, 2008 / Proposed Rules Compliance Procedures (1) Incorporate the operational limitations below by doing whichever of the following applies: (i) For airplanes with an airplane flight manual (AFM), pilot’s operating handbook (POH), or airplane flight manual supplement (AFMS), incorporate the language in the Appendix of this AD into the Limitations section of the AFM, POH, or AFMS (ii) For airplanes without an AFM, POH, or AFMS, do the following: (A) Incorporate the language in the Appendix of this AD into your aircraft maintenance records; and (B) Fabricate a placard (using at least 1/8-inch letters) with the following words and install the placard on the instrument panel within the pilot’s clear view: ‘‘THIS AD AND SUPERSEDED AD 2008–06–28 R1 CONTAIN LIMITATIONS REGARDING AVIDYNE PRIMARY FLIGHT DISPLAYS (PFD) AND REQUIRED INCORPORATION OF THESE LIMITATIONS INTO THE AIRCRAFT RECORDS. YOU MUST FOLLOW THESE LIMITATIONS.’’ Prior to further flight after the effective date of this AD.

Appendix to Docket No. FAA–2008–1210 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 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). VerDate Aug<31>2005 16:24 Nov 13, 2008 Jkt 217001 Procedures • 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 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 crosscheck flight instruments to make sure the information depicted on the PFD correlates and agrees with the information depicted on the backup instruments.

(GE) CF6–80A Series Turbofan Engines Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6–80A series turbofan engines with a high-pressure turbine rotor (HPTR) stage 1 disk, part number (P/N) 9367M45G06, installed. This proposed AD would require removing any HPTR stage 1 disk, P/N 9367M45G06, before exceeding 2,075 cycles-since-new (CSN). This proposed AD results from an error by GE that incorrectly cited a cyclic life of 12,600 CSN for the HPTR stage 1 disk, P/N 9367M45G06. We are proposing this AD to prevent the HPTR stage 1 disk from exceeding its part life which could cause fatigue cracks to start and grow. These cracks could result in a possible uncontained disk failure and damage to the airplane. DATES: We must receive any comments on this proposed AD by January 13, 2009. Use one of the following addresses to comment on this proposed AD. • Federal eRulemaking Portal: Go to https://www.regulations.gov and follow the instructions for sending your comments electronically. • Mail: Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

Displays (Part Numbers 700-00006-000, -001, -002, -003, and -100)

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-06-
28 R1, 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 R1 
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 and incorporate (if necessary) operational 
limitations. Since we issued AD 2008-06-28 R1, Avidyne developed a 
factory service procedure that will correct the problems on these 
Avidyne PFDs and also factory serviced certain serial number PFDs. 
Consequently, this proposed AD would retain the actions from AD 2008-
06-28 R1 until the affected PFD is factory serviced; add the actions of 
a label or marking check, an air data system performance verification 
test, and (if necessary) replacement of the PFD and factory servicing 
of the failed PFD; and reduce the serial number applicability from that 
of AD 2008-06-28 R1. We are proposing 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: We must receive comments on this proposed AD by January 13, 
2009.

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 required the 
following on Avidyne PFDs (P/Ns 700-00006-000, -001, -002, -003, and -
100) that are installed on airplanes:
     Checking of the maintenance records and inspection of the 
PFD (if necessary) to determine if an affected serial number PFD is 
installed; and
     If an affected serial number PFD is installed, 
incorporating information that limits operation when certain conditions 
for the PFD or backup instruments exist.
    An incorrect serial number (SN) listed in AD 2008-06-28 caused us 
to issue AD 2008-06-28 R1, Amendment 39-15468 (73 FR 19963, April 14, 
2008). AD 2008-06-28 R1 corrects the incorrect SN and retains the 
actions of AD-2008-06-28.
    Since we issued AD 2008-06-28 R1, Avidyne has prepared a factory 
service procedure that will correct the possible incorrect altitude and 
airspeed information displayed on these Avidyne PFDs and received 
approval for a corresponding alternative method of compliance (AMOC) to 
modify certain serial number PFDs at the factory, eliminating the 
unsafe condition in these units.
    This proposed AD retains the actions from AD 2008-06-28 R1 until 
the factory servicing is done. This proposed AD would require you to 
inspect for a label marked ``Deviation 08-19A'' on the exterior of the 
PFD near the TSO label or a ``MOD 52'' marking; if the label or mark is 
not present, do the PFD air data system performance verification test; 
if the PFD passes the test, remove the operational limitations 
requirement; or if the PFD does not pass the test, remove the PFD, have 
the PFD factory serviced, install a PFD that has passed the air data 
system verification test or has been factory serviced (PFD bears a 
label marked ``Deviation 08-19A'' on the exterior of the PFD near the 
TSO label; or a ``MOD 52'' marking); and

[[Page 67430]]

remove the operational limitations requirement. This proposed AD also 
reduces the serial number applicability from that of AD 2008-06-28 R1 
due to Avidyne modifying PFDs at the factory.
    This condition, if not corrected, 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.

Relevant Service Information

    We have reviewed Avidyne Service Bulletin No. 601-00006-096, 
Revision 1, dated July 14, 2008.
    The service information describes procedures for:
     Identifying possible Avidyne PFDs by serial number;
     Identifying PFDs that have already been serviced;
     Doing Avidyne PFD air data system performance verification 
test procedures; and
     Having any Avidyne PFD that has not passed the air data 
system verification test or has not been factory serviced (PFD does not 
bears a label marked ``Deviation 08-19A'' on the exterior of the PFD 
near the TSO label; or a ``MOD 52'' marking) serviced.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would supersede AD 2008-06-28 R1 with a new AD that would retain the 
actions from AD 2008-06-28 R1 until the affected PFD is factory 
serviced; add the actions of a label or marking check, an air data 
system performance verification test, and (if necessary) replacement of 
the PFD and factory servicing of the failed PFD; and reduce the serial 
number applicability from that of AD 2008-06-28 R1. This proposed AD 
would require you to use the service information described previously 
to perform these actions.

Differences Between This Proposed AD and the Service Information

    The proposed AD includes terminating action for the requirement of 
AD 2008-06-28 R1 to incorporate information that limits operation when 
certain conditions for the PFD or backup instruments exist. The 
requirements of this proposed AD, if adopted as a final rule, would 
take precedence over the provisions in the service information.

Costs of Compliance

    We estimate that this proposed AD would affect 384 airplanes in the 
U.S. registry.
    We estimate the following costs to do the proposed serial number 
determination:

----------------------------------------------------------------------------------------------------------------
                                                                                Total cost  per   Total cost  on
                  Labor cost                              Parts cost                airplane     U.S.  operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80.............  Not applicable.................             $80          $30,720
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary test and 
replacement that would be required based on the results of the proposed 
test. We have no way of determining the number of airplanes that may 
need this test and replacement:

------------------------------------------------------------------------
                                                         Total cost  per
            Labor cost                  Parts cost           airplane
------------------------------------------------------------------------
4 work-hours x $80 per hour =      Not applicable......            $320
 $320.
------------------------------------------------------------------------

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 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.
    For the reasons discussed above, I certify that the 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 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 proposed AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the proposed AD, the 
regulatory evaluation, any comments received, and other information on 
the Internet at https://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.

STC No. SA09543AC-D incorporated); and
    (8) Piper Aircraft, Inc. Models PA-28-161, PA-28-181, PA-28R-
201, PA-32R-301 (HP), PA-32R-301T, PA-32-301FT, PA-32-301XTC, PA-34-
220T, PA-44-180, PA-46-350P, PA-46R-350T, and PA-46-500TP.
    (d) If you have one of the affected part number PFDs installed 
on your airplane, you must be able to positively show that it is not 
one of the affected serial numbers or comply with paragraph (f), all 
subparagraphs, as applicable in this AD. You must follow the actions 
in the paragraphs below to determine what actions of paragraph (f) 
apply. Under 14 CFR 43.7, the owner/operator holding at least a 
private pilot certificate is allowed to do the check in paragraph 
(d)(1) of this AD. All other actions must be done by a certificated 
mechanic, unless noted differently.
    (1) Do a logbook check of aircraft records (previously referred 
to in AD 2008-06-28 R1 as ``maintenance records'') to determine if 
any PFD (P/Ns 700-00006-000, 700-00006-001, 700-00006-002, 700-
00006-003, or 700-00006-100) with any affected serial number listed 
in Avidyne Service Bulletin No. 601-00006-096, Revision 1, dated 
July 14, 2008, is installed.
    (i) If, as a result of the logbook check, you positively 
identify that the PFD installed does not have a serial number 
affected by this AD, then only paragraph (f)(5) of this AD applies 
to you.
    (ii) If, as a result of the logbook check, you cannot positively 
identify the serial number of the PFD, do the visual inspection 
required in paragraph (d)(2) of this AD.
    (iii) If, as a result of the logbook check, you find any PFD 
installed with an affected serial number, do the actions required by 
paragraph (f) of this AD, including all subparagraphs as applicable.
    (2) If, as a result of the above logbook check, you cannot 
positively identify the serial number of the PFD, visually inspect 
any PFD (P/Ns 700-00006-000, 700-00006-001, 700-00006-002, 700-
00006-003, or 700-00006-100) for any affected serial number listed 
in Avidyne Service Bulletin No. 601-00006-096, Revision 1, dated 
July 14, 2008.
    (i) If, as a result of this visual inspection, you positively 
identify that the PFD installed does not have a serial number 
affected by this AD, then only paragraph (f)(5) of this AD applies 
to you.
    (ii) If, as a result of this visual inspection, you identify 
that the PDF installed does have a serial number affected by this 
AD, do the actions required in paragraph (f) of this AD, including 
all subparagraphs as applicable.

Unsafe Condition

    (e) This AD results from several field reports of Avidyne PFDs 
displaying incorrect altitude and airspeed information and Avidyne 
preparing a factory service procedure that will correct the possible 
incorrect altitude and airspeed information displayed. 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.

Compliance

    (f) To address this problem, you must do the following, unless 
already done:

Appendix to Docket No. FAA-2008-1210 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 
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 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 crosscheck flight instruments to 
make sure the information depicted on the PFD correlates and agrees 
with the information depicted on the backup instruments.
