Airworthiness Directives; Pilatus Aircraft Ltd. Model PC-12/47E

Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) issued by the 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. This condition has been reported to correct itself after several minutes.

This situation, if not corrected, could result in an undesired bank angle, which would constitute an unsafe condition.

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES: This AD becomes effective April 20, 2009.

On April 20, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this

AD.

We must receive comments on this AD by May 15, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

On February 12, 2009, we issued AD 2009-04-14, Amendment 39-15820

(74 FR 7810; February 20, 2009). That AD required actions intended to address an unsafe condition on the products listed above.

Page 17385

Since we issued AD 2009-04-14, we have received new MCAI that requires a revision of the operational procedures to be inserted into the pilot's operating handbook (POH).

The European Aviation Safety Agency (EASA), which is the Technical

Agent for the Member States of the European Community, has issued

Emergency AD No. 2009-0080-E, dated April 3, 2009 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The 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. This condition has been reported to correct itself after several minutes.

This situation, if not corrected, could result in an undesired bank angle, which would constitute an unsafe condition.

As an interim measure, EASA Emergency AD 2009-0028-E required the introduction of a maximum bank angle during climb. As a result of the ongoing investigation, the problem can be temporarily solved with some limitations in the take-off procedure.

For the reason described above, this AD supersedes EASA AD 2008- 0028-E and requires a revision of the operational procedures to be inserted into the POH. This action is still considered to be an interim solution and further AD action is likely to follow.

You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Pilatus Aircraft Ltd. has issued Temporary Revision No. 11 to PC- 12/47E Pilot's Operating Handbook, Report No. 02277, dated March 18, 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

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 have also required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the current FAA AD and the previous EASA emergency AD are not satisfying the unsafe condition. Operators must follow the new procedures to assure the unsafe condition is adequately addressed. Therefore, 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 opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2009-0347; Directorate

Identifier 2009-CE-022-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because 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 about 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.

List of Subjects in 14 CFR Part 39

Adoption of the Amendment 0

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows:

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

Page 17386

Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Amendment 39-15820 (74 FR 7810; February 20, 2009), and adding the following new AD: 2009-08-10 Pilatus Aircraft Ltd: Amendment 39-15883; Docket No. FAA- 2009-0347; Directorate Identifier 2009-CE-022-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective April 20, 2009.

Affected ADs

(b) This AD supersedes AD 2009-04-14, Amendment 39-15820.

Applicability

(c) This AD applies to Models PC-12/47E airplanes, manufacturer serial numbers (MSN) 545 and MSN 1001 and subsequent, 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. This condition has been reported to correct itself after several minutes.

This situation, if not corrected, could result in an undesired bank angle, which would constitute an unsafe condition.

As an interim measure, EASA Emergency AD 2009-0028-E required the introduction of a maximum bank angle during climb. As a result of the ongoing investigation, the problem can be temporarily solved with some limitations in the take-off procedure.

For the reason described above, this AD supersedes EASA AD 2008- 0028-E and requires a revision of the operational procedures to be inserted into the POH. This action is still considered to be an interim solution and further AD action is likely to follow.

Actions and Compliance

(f) Unless already done, before further flight as of April 20, 2009 (the effective date of this AD), do the following actions:

(1) Incorporate Pilatus Aircraft Ltd. Temporary Revision No. 11 to PC-12/47E Pilot's Operating Handbook, Report No. 02277, dated

March 18, 2009, into the Pilatus PC-12/47E POH.

(2) Remove the information and/or the copy of AD 2009-04-14 required by AD 2009-04-14 to be inserted in the POH.

(3) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation

Regulations 14 CFR 43.7 may do the actions required in this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following 14 CFR 43.9.

FAA AD Differences

Note: This AD differs from the MCAI and/or service information as follows:

(1) Since we never allowed incorporating Temporary Revision No. 9, dated January 30, 2009, into the POH, we are not requiring the removal of Temporary Revision No. 9, dated January 30, 2009, as the

MCAI requires.

(2) Current regulations (1 CFR 51.7) do not allow us to both incorporate by reference a service document and write the provisions of that document in the AD. We have chosen to incorporate by reference the temporary revision.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager,

Standards Office, 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: Doug Rudolph, Aerospace Engineer, FAA, Small

Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090. 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.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered

FAA-approved if they are approved by the State of Design Authority

(or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44

U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned

OMB Control Number 2120-0056.
