SUMMARY: We are adopting a new 

airworthiness directive (AD) to 

supersede AD 2008–06–28 R1, which 

applies to certain Avidyne Corporation

(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: 

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:

4 work-hours × $80 per hour = $320 ........................................................................... 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.

Displays (PFDs), part numbers (P/Ns) 700– 

00006–000, 700–00006–001, 700–00006–002, 

700–00006–003, and 700–00006–100 with 

any serial number listed in Avidyne Service 

Bulletin No. 601–00006–096, Revision 1, 

dated July 14, 2008. Paragraph (d) of this AD 

gives procedures to determine if an affected 

serial number is installed on your airplane. 

This AD applies to affected serial number 

PFDs that are installed on, but not limited to 

the airplanes below that are certificated in 

any category. 

(1) Adam Aircraft Model A500; 

(2) Cessna Aircraft Company Model 441 

(STEC Alliant Supplemental Type Certificate 

(STC) No. SA09547AC–D incorporated); 

(3) Cessna Aircraft Company Models 

LC42–550FG and LC41–550FG (Columbia 

Aircraft Manufacturing and The Lancair 

Company previously held the type certificate 

for these airplanes); 

(4) Cirrus Design Corporation Models SR20

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 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/

Federal Register / Vol. 74, No. 38 / Friday, February 27, 2009 / Rules and Regulations 8859 

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: 

Actions 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 

Prior to further flight after April 3, 2009 (the 

effective date of this AD). 

Under 14 CFR 43.7, the owner/operator holding at least a private pilot certificate is allowed to insert the information into the 

AFM, POH, AFMS, or maintenance records 

as required in paragraph (f)(1)(i) or 

(f)(1)(ii)(A) of this AD and fabricate the 

placard required in paragraph (f)(1)(ii)(B) of 

this AD. Make an entry into the aircraft 

records showing compliance with these portions of the AD in accordance with 14 CFR 

43.9. 

(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.’’ 

(2) Inspect for a label marked ‘‘Deviation 08– 

19A’’ on the exterior of the PFD near the 

TSO label or a ‘‘MOD 52’’ marking. 

(i) If the label marked ‘‘Deviation 08–19A’’ 

or ‘‘MOD 52’’ marking is present, then 

the PFD has received the factory modification. Remove the limitations required 

by paragraph (f)(1) of this AD and AD 

2008–06–28 R1. Except for the actions 

of paragraph (f)(5) of this AD, no further 

action is required by this AD. 

Within the next 15 days after April 3, 2009 

(the effective date of this AD). 

Follow Avidyne Service Bulletin No. 601– 

00006–096, Revision 1, dated July 14, 

2008. 

(ii) If the label or marking is not present, do 

the PFD air data system performance 

verification test in Section 3.3 of the referenced service bulletin. 

(3) If the PFD passes the test required in paragraph (f)(2)(ii) of this AD, remove the limitations required by paragraph (f)(1) of this AD 

and AD 2008–06–28 R1. Except for the actions of paragraph (f)(5) of this AD, no further 

action is required by this AD. 

Within the next 15 days after April 3, 2009 

(the effective date of this AD). 

Follow Avidyne Service Bulletin No. 601– 

00006–096, Revision 1, dated July 14, 

2008. 

(4) If the PFD does not pass the test required 

in paragraph (f)(2)(ii) of this AD, do the following: 

(i) Remove the PFD, install a PFD that has 

passed the air data system performance 

verification test, has been factory modified (PFD bears a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD 

near the TSO label or a ‘‘MOD 52’’ 

marking), or is not one of the affected 

serial number PFDs; 

Within the next 15 days after April 3, 2009 

(the effective date of this AD). 

Follow Avidyne Service Bulletin No. 601– 

00006–096, Revision 1, dated July 14, 

2008. 

(ii) Remove the limitations required by 

paragraph (f)(1) of this AD and AD 

2008–06–28 R1; and 

(iii) Except for the actions of paragraph 

(f)(5) of this AD, no further action is required by this AD.

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.

14 CFR Part 39 

[Docket No. FAA–2009–0159; Directorate 

Identifier 2008–NM–175–AD; Amendment 

39–15828; AD 2009–05–04]

Airworthiness Directives; Bombardier 

Model CL–215–6B11 (CL–215T Variant) 

and CL–215–6B11 (CL–415 Variant) 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Bombardier Model CL–215–6B11 (CL– 

215T variant) and CL–215–6B11 (CL– 

415 variant) airplanes. This AD requires 

repetitive inspections for contamination 

of grease, bearing wear checks, grease 

applications of the rudder lower torque 

tube upper bearing, and a rudder upper 

hinge gap check; and related 

investigative and corrective actions if 

necessary. This AD results from a report 

of corrosion on the rudder lower torque 

tube upper bearing. We are issuing this 

AD to detect and correct corroded 

bearings which could lead to hinge 

deformation, and could result in a 

rudder jam and consequent reduced 

controllability of the airplane. 

DATES: This AD becomes effective 

March 16, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of March 16, 2009. 

We must receive comments on this 

AD by March 30, 2009. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251.
