Airworthiness Directives; Pacific Aerospace Corporation, Ltd. 
Model 750XL Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Pacific Aerospace Corporation, Ltd. (Pacific Aerospace) Model 
750XL airplanes. This proposed AD would require you to replace any type 
TLP-D or TLED rivets on the aileron pushrod ends and elevator control 
pushrod ends. This proposed AD results from mandatory continuing 
airworthiness information (MCAI) issued by the airworthiness authority 
for New Zealand. We are issuing this proposed AD to replace the above 
identified rivets on the aileron pushrod ends and elevator control 
pushrod ends, which, if not replaced, could result in loose mechanical 
elements in the control systems. This could lead to control anomalies 
and loss of airplane control.

DATES: We must receive any comments on this proposed AD by December 27, 
2004.

ADDRESSES: Use one of the following to submit comments on this proposed 
AD:
    <bullet> DOT Docket Web site: Go to http://dms.dot.gov and follow 
the

Discussion

    What events have caused this proposed AD? The Civil Aviation 
Authority (CAA), which is the airworthiness authority for New Zealand, 
recently notified FAA that an unsafe condition may exist on all Pacific 
Aerospace Corporation, Ltd. (Pacific Aerospace) Model 750XL airplanes. 
The CAA reports occurrences of loose type TLP-D or TLED rivets on the 
aileron pushrod ends and elevator control pushrod ends on Model 750XL 
airplanes in service in New Zealand.
    What is the potential impact if FAA took no action? Any type TLP-D 
or TLED rivets on the aileron pushrod ends and elevator control pushrod 
ends could result in loose mechanical elements in the control systems. 
This could lead to control anomalies and loss of airplane control.
    Is there service information that applies to this subject? Pacific 
Aerospace has issued Mandatory Service Bulletin No. PACSB/XL/007, dated 
June 22, 2004.
    What are the provisions of this service information? The service 
bulletin includes procedures for:

--Inspecting for any type TLP-D or TLED rivets on the aileron pushrod 
ends and elevator control pushrod ends; and
--Replacing any type TLP-D or TLED rivets found on the aileron pushrod 
ends and elevator control pushrod ends with new Cherry Max 3213-4-2 or 
3243-4-2 (oversize nominal \1/8\-inch) rivets.

    What action did the CAA take? The CAA classified this service 
bulletin as mandatory and issued New Zealand AD Number DCA/40XL/1, 
dated June 24, 2004, to ensure the continued airworthiness of these 
airplanes in New Zealand.
    Did the CAA inform the United States under the bilateral 
airworthiness agreement? These Pacific Aerospace Model 750XL airplanes 
are manufactured in New Zealand and are type-certificated for operation 
in the United States under the provisions of section 21.29 of the 
Federal Aviation Regulations (14 CFR 21.29) and the applicable 
bilateral airworthiness agreement.
    Under this bilateral airworthiness agreement, the CAA has kept us 
informed of the situation described above.

FAA's Determination and Requirements of This Proposed AD

    What has FAA decided? We have examined the CAA's findings, reviewed 
all available information, and determined that AD action is necessary 
for products of this type design that are certificated for operation in 
the United States.
    Since the unsafe condition described previously is likely to exist 
or develop on other Pacific Aerospace Model 750XL airplanes of the same 
type design that are registered in the United States, we are proposing 
AD action to replace any type TLP-D or TLED rivets on the aileron 
pushrod ends and elevator control pushrod ends, which, if not replaced, 
could result in loose mechanical elements in the control systems. This 
could lead to control anomalies and loss of airplane control.
    What would this proposed AD require? This proposed AD would require 
you to replace any type TLP-D or TLED rivets on the aileron pushrod 
ends and elevator control pushrod ends.
    How does the revision to 14 CFR part 39 affect this proposed AD? On 
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 
47997, July 22, 2002), which governs FAA's AD system. This regulation 
now includes material that relates to altered products, special flight 
permits, and alternative methods of compliance. This material 
previously was included in each individual AD. Since this material is 
included in 14 CFR part 39, we will not include it in future AD 
actions.

Costs of Compliance

    How many airplanes would this proposed AD impact? We estimate that

[[Page 67866]]

this proposed AD affects 6 airplanes in the U.S. registry.
    What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to 
do this proposed replacement of any type TLP-D or TLED rivets on the 
aileron pushrod ends and elevator control pushrod ends:

----------------------------------------------------------------------------------------------------------------
                                                                      Total cost per      Total cost on U.S.
               Labor cost                         Parts cost             airplane              Operators
----------------------------------------------------------------------------------------------------------------
6 workhours x $65 per hour = $390.......  $37 for 100 Cherry Max                $427  $427 x 6 = $3,562.
                                           3213-4-2 or 3243-4-2
                                           (oversize nominal \1/8\-
                                           inch) rivets.
----------------------------------------------------------------------------------------------------------------

    The Cherry Max 3213-4-2 or 3243-4-2 rivets are available in a 
specially sealed 100-count package. The costs above cover this 100-
count package although you may need less than 100 rivets.

Regulatory Findings

    Would this proposed AD impact various entities? We have determined 
that this proposed AD would not have federalism implications under 
Executive Order 13132. This proposed AD would 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.
    Would this proposed AD involve a significant rule or regulatory 
action? For the reasons discussed above, I certify that this proposed 
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 proposed AD 
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 
``AD Docket FAA-2004-19444; Directorate Identifier 2004-CE-33-AD'' in 
your request.
    This proposed rulemaking is promulgated under the authority in 
Subtitle VII, Part A, Subpart III, Section 44701, General requirements. 
Under that section, the FAA is charged with prescribing minimum 
standards required in the interest of safety for the design of 
aircraft. This proposed regulation is within the scope of that 
authority since it corrects an unsafe condition in the design of the 
aircraft caused by type TLP-D or TLED rivets, which, if not replaced, 
could result in loose mechanical elements in the control systems. This 
could lead to control anomalies and loss of airplane control.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 14 
CFR part 39 as follows:

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


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new 
airworthiness directive (AD):

Pacific Aerospace Corporation, Ltd.: Docket No. FAA-2004-19444; 
Directorate Identifier 2004-CE-33-AD

When Is the Last Date I can Submit Comments on This Proposed AD?

    (a) We must receive comments on This proposed airworthiness 
directive (AD) by December 27, 2004.
