paragraph (f)(2) of this AD is done. 

(2) For airplanes on which the inspection 

specified in paragraph (f)(1)(ii) of this AD is 

done: Within 4,500 flight cycles from the 

effective date of this AD, do the inspection 

and applicable corrective actions required by 

paragraph (f)(1)(i) of this AD. Doing the 

inspection and applicable corrective actions 

required by paragraph (f)(1)(i) of this AD 

terminates the repetitive inspections required 

by paragraph (f)(1)(ii) of this AD. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

Airbus Mandatory Service Bulletin A340– 

71–4007, dated April 1, 2009; does not 

contain corrective actions if damage is found 

during the inspection of the forward engine 

mounts. The corrective actions are specified 

in Task 71–21–11–210–801–0 of the Airbus 

A340 Aircraft Maintenance Manual, Revision 

68, dated October 1, 2009. Therefore, this AD 

refers to Task 71–21–11–210–801–0 of the 

Airbus A340 Aircraft Maintenance Manual, 

Revision 68, dated October 1, 2009, for the 

inspection and corrective actions.

AGENCY: Federal Aviation 

Administration (FAA), Department of

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Field reports have indicated that the 

possibility exists that both Primary Flight 

Displays (PFDs) could indicate a roll attitude 

offset of up to 10 degrees in the same 

direction if an accelerated turn onto the 

active runway is performed immediately 

followed by take-off. In addition, 

annunciated heading splits have been 

reported. This condition has been reported to 

correct itself after several minutes. 

Additionally, if the aeroplane is operating 

in geographical latitudes with low horizontal 

magnetic field strength, incorrect heading 

may be displayed if the ADAHRS switches 

from GPS track to magnetometer heading 

while the aeroplane is on the ground.

8474 Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Rules and Regulations 

This situation, if not corrected, could result 

in an undesired bank angle, heading splits 

and/or incorrect heading, which would 

constitute an unsafe condition. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective April 

1, 2010. 

On April 1, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of Honeywell

this AD. 

As of April 20, 2009 (74 FR 17384, 

April 15, 2009), the Director of the 

Federal Register approved the

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on December 10, 2009 (74 FR 

65493), and proposed to supersede AD 

2009–08–10, Amendment 39–15883 (74 

FR 17384, April 15, 2009). That NPRM 

proposed to correct an unsafe condition 

for the specified products. The MCAI 

states that: 

Field reports have indicated that the 

possibility exists that both Primary Flight 

Displays (PFDs) could indicate a roll attitude 

offset of up to 10 degrees in the same 

direction if an accelerated turn onto the 

active runway is performed immediately 

followed by take-off. In addition, 

annunciated heading splits have been 

reported. This condition has been reported to 

correct itself after several minutes. 

Additionally, if the aeroplane is operating 

in geographical latitudes with low horizontal 

magnetic field strength, incorrect heading 

may be displayed if the ADAHRS switches 

from GPS track to magnetometer heading 

while the aeroplane is on the ground. 

This situation, if not corrected, could result 

in an undesired bank angle, heading splits 

and/or incorrect heading, which would 

constitute an unsafe condition. 

As a short-term interim measure, AD 2009– 

0028–E has been released in February 2009 

to limit at 30° the bank angle during climb. 

Afterwards, as a result of the ongoing 

investigation, the problem has been 

temporarily addressed with some limitations 

in the take-off procedure. These limitations 

have been mandated by AD 2009–0080–E 

which superseded AD 2009–0028–E. 

In order to terminate the operational 

limitations, an updated ADAHRS version 

with improved software was developed. 

For the reasons described above, this AD 

supersedes AD 2009–0080–E and mandates 

as a terminating action either an update of 

the ADAHRS software or the replacement of 

the ADAHRS unit. 

From MSN 1181 and subsequent an 

improved ADAHRS unit was implemented 

during production. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

Comment Issue No. 1: Limit the 

Applicability to Manufacturer Serial 

Numbers (MSN) 545, and 1001 Through 

1180 

Mr. Scott Lania, Alpha Flying, Inc., 

requests limiting the applicability to 

MSN 545, and 1001 through 1180, 

which have the affected air data, 

attitude, and heading reference system 

(ADAHRS) unit installed. Paragraph 

(f)(4) of the proposed AD addresses the 

issue of installing one of the affected 

ADAHRS units on other Pilatus Model 

PC–12/47E airplanes. 

Mr. Lania requests this change in the 

applicability since Pilatus is installing a 

new version of the ADAHARS at 

production on MSN 1181 and 

subsequent. 

The FAA partially agrees with the 

commenter. We agree that Pilatus is 

installing a new version of the ADAHRS 

in production. However, we disagree 

with changing the applicability of this 

AD. To prevent future installation of the 

defective ADAHARS unit on airplanes, 

the applicability must be for all 

airplanes, thus preventing the 

introduction of the unsafe condition on 

these airplanes. Paragraph (f)(4), which 

prohibits installation of the affected 

ADAHRS on other Pilatus Model PC– 

12/47E airplanes, would not apply 

unless the applicability was for all 

airplanes. 

We are not changing the final rule AD 

action based on this comment. 

Comment Issue No. 2: Use ‘‘Serviceable’’ 

or ‘‘Modified’’ in Describing the 

ADAHRS Unit 

Mr. Lania also requests that the word 

‘‘new’’ in paragraph (f)(2)(ii) of the 

Actions and Compliance section of the 

proposed AD be replaced with the word 

‘‘serviceable’’ or ‘‘modified.’’ 

Mr. Lania states that when 

accomplishing the Pilatus service 

bulletin to comply with this AD, the 

ADAHRS unit is not being replaced 

with a new unit; instead, it is being 

modified with upgraded software and 

the data plate of the ADAHRS unit is 

being changed to the new part number 

(P/N). Mr. Lania concludes that in the 

accomplishment of this AD on all the 

affected airplanes, relatively few, if any, 

of the ADAHRS units will be replaced 

with new units. 

We disagree with the commenter. The 

word ‘‘new’’ refers to a new Honeywell 

unit from the manufacturer, so the word 

‘‘serviceable’’ is not an appropriate 

substitution here. We believe the 

commenter’s intent is to use modified 

components instead of getting a new 

ADAHRS unit. The use of modified 

components is addressed in paragraph 

(f)(2)(i) of the proposed AD. In 

paragraph (f)(2)(i) of the proposed AD, 

the operator may accomplish the 

Honeywell service bulletin, which 

changes the P/N after the unit gets new 

software uploaded. 

We are not changing the final rule AD 

action based on this comment. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

50 products of U.S. registry. We also 

estimate that it will take about 6 workVerDate Nov<24>2008 16:14 Feb 24, 2010 Jkt 220001 PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 E:\FR\FM\25FER1.SGM 25FER1

Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Rules and Regulations 8475 

hours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. 

Based on these figures, we estimate 

the cost of this AD to the U.S. operators 

to be $25,500 or $510 per product. 

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 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 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 AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Amendment 39–15883 (74 FR 

17384, April 15, 2009) and adding the 

following new AD: 

2010–05–02 Pilatus Aircraft Ltd.: 

Amendment 39–16211; Docket No. 

FAA–2009–1158; Directorate Identifier 

2009–CE–063–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 1, 2010. 

Affected ADs 

(b) This AD supersedes AD 2009–08–10, 

Amendment 39–15883. 

Applicability 

(c) This AD applies to Model PC–12/47E 

airplanes, all manufacturer serial numbers 

(MSN), certificated in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 34: Navigation. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Field reports have indicated that the 

possibility exists that both Primary Flight 

Displays (PFDs) could indicate a roll attitude 

offset of up to 10 degrees in the same 

direction if an accelerated turn onto the 

active runway is performed immediately 

followed by take-off. In addition, 

annunciated heading splits have been 

reported. This condition has been reported to 

correct itself after several minutes. 

Additionally, if the aeroplane is operating 

in geographical latitudes with low horizontal 

magnetic field strength, incorrect heading 

may be displayed if the ADAHRS switches 

from GPS track to magnetometer heading 

while the aeroplane is on the ground. 

This situation, if not corrected, could result 

in an undesired bank angle, heading splits 

and/or incorrect heading, which would 

constitute an unsafe condition. 

As a short-term interim measure, AD 2009– 

0028–E has been released in February 2009 

to limit at 30° the bank angle during climb. 

Afterwards, as a result of the ongoing 

investigation, the problem has been 

temporarily addressed with some limitations 

in the take-off procedure. These limitations 

have been mandated by AD 2009–0080–E 

which superseded AD 2009–0028–E. 

In order to terminate the operational 

limitations, an updated ADAHRS version 

with improved software was developed. 

For the reasons described above, this AD 

supersedes AD 2009–0080–E and mandates 

as a terminating action either an update of 

the ADAHRS software or the replacement of 

the ADAHRS unit. 

From MSN 1181 and subsequent an 

improved ADAHRS unit was implemented 

during production. 

Actions and Compliance 

(f) Unless already done, do the following 

actions:

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

The Civil Aviation Authority of the United 

Kingdom (UK) has informed EASA 

[European Aviation Safety Agency] that 

significant quantities of Halon 1211 gas, 

determined to be outside the required 

specification, have been supplied to the 

aviation industry for use in fire extinguishing 

equipment. * * * 

* * * * * 

* * * This Halon 1211 has subsequently 

been used to fill certain * * * portable fire 

extinguishers that are now likely to be 

installed in or carried on board ATR 

aeroplanes. 

The contaminated nature of this gas, when 

used against a fire, may provide reduced fire 

suppression, endangering the safety of the 

aeroplane and its occupants. In addition, 

extinguisher activation may lead to the 

release of toxic fumes, possibly causing 

injury to aeroplane occupants. 

* * * * * 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

March 12, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of March 12, 2010. 

We must receive comments on this 

AD by April 12, 2010. 

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.
