2010-17-09 PILATUS AIRCRAFT LTD.: Amendment 39-16401; Docket No. FAA-2010-0583; Directorate Identifier 2010-CE-028-AD. 
EFFECTIVE DATE

(a) This  airworthiness  directive  (AD)  becomes  effective September 22,
    2010.

AFFECTED ADS

(b) None.

APPLICABILITY

(c) This  AD  applies  to Model PC-12/47E airplanes,  manufacturer  serial
    numbers (MSN)  1001 and  MSN 1003  through 1140,  certificated in  any
    category.

SUBJECT

(d) Air Transport Association of America (ATA) Code 76: Engine Controls.

REASON

(e) The mandatory continuing airworthiness information (MCAI) states:

    Reports  have  been received  indicating  that, if  the  power control
    friction wheel is  tightened, the reverse  thrust latch may  stick and
    subsequently allow the Power  Control Lever (PCL) to  be inadvertently
    retarded aft of the idle detent.

    This condition, if  not corrected, could  result in undesired  reverse
    thrust activation which, especially  during approach, could result  in
    reduced control of the aeroplane.

    For the reason described above, this AD requires an inspection of  the
    PCL reverse thrust latch and the accomplishment of corrective  actions
    as necessary.

ACTIONS AND COMPLIANCE

(f) Unless already done, do the following actions:

(1) Within 30 days after September 22, 2010 (the effective  date  of  this
    AD), inspect the power control  lever reverse thrust latch handle  for
    free movement following  the accomplishment instructions  in paragraph
    3.A.  of  Pilatus Aircraft  Ltd. Service  Bulletin No:  76-002,  dated
    October 15, 2009.

(2) If during the inspection required in paragraph (f)(1) of this  AD  you
    determine the reverse  thrust latch sticks  or the idle  detent is not
    present, do the following actions:

(i) Before  further  flight, insert Temporary Revision No. 12 to PC-12/47E
    Pilot's Operating Handbook,  dated October 15,  2009, into the  normal
    procedures section of the aircraft flight manual (AFM).

(ii) Within 12 months after September 22, 2010 (the effective date of this
     AD),  modify  the  engine  control  console  assembly  following  the
     accomplishment  instructions in  paragraph 3.B.  of Pilatus  Aircraft
     Ltd. Service Bulletin No: 76-002, dated October 15, 2009.

(iii) Before further flight after the modification required  by  paragraph
      (f)(2)(ii) of this AD, remove Temporary Revision No. 12 to PC-12/47E
      Pilot's Operating Handbook, dated October 15, 2009, from the AFM.

(3) If during the inspection specified in  paragraph (f)(1) of this AD you
    determine the reverse thrust latch moves freely and the idle detent is
    present, no further action is required.

FAA AD DIFFERENCES

NOTE: This AD differs from the MCAI and/or service information as follows:
No differences.

PREAMBLE 

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

ACTION: Final rule.

SUMMARY: We are adopting a new 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:

Reports have been received indicating that, if the power control friction wheel is tightened, the reverse thrust latch may stick and subsequently allow the Power Control Lever (PCL) to be inadvertently retarded aft of the idle detent.
This condition, if not corrected, could result in undesired reverse thrust activation which, especially during approach, could result in reduced control of the aeroplane.

We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES: This AD becomes effective September 22, 2010.
On September 22, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590.

FOR FURTHER INFORMATION CONTACT: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090.

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 June 10, 2010 (75 FR 32863). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Reports have been received indicating that, if the power control friction wheel is tightened, the reverse thrust latch may stick and subsequently allow the Power Control Lever (PCL) to be inadvertently retarded aft of the idle detent.
This condition, if not corrected, could result in undesired reverse thrust activation which, especially during approach, could result in reduced control of the aeroplane.
For the reason described above, this AD requires an inspection of the PCL reverse thrust latch and the accomplishment of corrective actions as necessary.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data 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 80 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S. operators to be $6,800 or $85 per product.
In addition, we estimate that any necessary follow-on actions would take about 9 work-hours and require parts costing $100, for a cost of $865 per product. We have no way of determining the number of products that may need these actions.

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.
