Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) to 
supersede AD 2008-06-28 R1, which applies to certain Avidyne 
Corporation (Avidyne) Primary Flight Displays

[[Page 8857]]

(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 modification 
that will correct the problems on these Avidyne PFDs and also factory 
modified certain serial number PFDs. To terminate the operational 
limitations of AD 2008-06-28 R1, this AD adds actions to assure any 
affected serial number PFD complies with one of the following: Passes 
the air data system performance verification test, receives the factory 
modification, or is replaced with a PFD that has complied with one of 
the previous two conditions or is not one of the affected serial number 
PFDs. Consequently, this AD will retain the actions from the previous 
AD until the added terminating action has been complied with. 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 3, 2009.
    On April 3, 2009, the Director of the Federal Register approved the 
incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    On November 7, 2008, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to certain Avidyne PFDs P/Ns 700-00006-000, -001, -002, -
003, and -100 that are installed on airplanes. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on November 14, 2008 (73 FR 67429). The NPRM proposed to 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.

Comments

    We provided the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and FAA's response to the comment:

Comment Issue: Affected Units Identified in Service Information

    Mr. Frederic Barber, Avidyne Corporation, comments that Avidyne has 
updated their service information and issued Revision 2. He notes the 
test and repair requirements remain unchanged, but the list of serial 
numbers has been updated to remove those PFDs known to have been 
serviced since Revision 1 was published. Mr. Barber recommends that the 
proposed AD be modified to reference Revision 2.
    We do not agree that the proposed AD be modified to reference 
Revision 2 of the service information. Some units may have already had 
the modification done per Revision 1 and these serial numbers may be 
reflected in the Revision 2 of the service information. Paragraph 35.c. 
of FAA AD Manual, FAA-IR-M-8040.1B (FAA-AIR-M-8040.1), dated May 28, 
2008, reads:

    The fact that an AD has been complied with by all owners/
operators does not make the AD (the change in type design) 
unnecessary. Therefore, an AD must never be removed based on the 
representation of a manufacturer that all affected aircraft are in 
compliance with the AD, or the information that there are no 
affected aircraft left on the U.S. registry.

    With this in mind, we have determined that we also should not base 
the applicability on the manufacturer's assurance that certain units 
have since been modified, but rather should base the applicability on 
those units that originally needed the modification. The ``unless 
already done'' phrase in the AD would give AD credit to those that have 
already incorporated the modification.
    We are not changing the final AD rule action as a result of this 
comment.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 384 airplanes in the U.S. 
registry.
    We estimate the following costs to do the 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:

------------------------------------------------------------------------
4 work-hours x $80 per hour =      Not applicable......            $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 AD.

Regulatory Findings

    We have 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 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 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 ``Docket 
No. FAA-2008-1210; Directorate Identifier 2008-CE-047-AD'' in your 
request.

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 positively show that it is not one of the 
affected serial numbers or comply with paragraph (f), all 
subparagraphs, as applicable in this AD. 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 modification 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 Airworthiness Directive 2009-05-05 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.
