Airworthiness Directives; Pacific Aerospace Limited Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Pacific Aerospace Limited (PAL) Model 750XL airplanes. This proposed 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 PAL Model 750XL airplanes manufactured with 
only one attitude indicator. A second attitude indicator is required 
for flights under instrument flight rules. We are issuing this proposed 
AD to require actions to address the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by January 22, 
2015.

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.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for New Zealand, has issued AD DCA/750XL/17A, dated November 
6, 2014 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for Pacific Aerospace Limited Model 750XL airplanes and was 
based on mandatory continuing airworthiness information originated by 
an aviation authority of another country. The MCAI states:

    This AD with effective date 10 November 2014 is prompted by a 
recent determination that certain PAL750XL aircraft were 
inadvertently manufactured with instrument panels with only one 
Attitude Indicator (AI). A second AI is required for PAL750XL 
operating under Instrument Flight Rules (IFR).
    The AD mandates the installation of either a second AI, or the 
enablement of Reversionary Attitude mode in the Sandel Electronic 
Horizontal Situation Indicator (EHSI), if fitted, when operating 
under IFR.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2014-1002.

Relevant Service Information

    Pacific Aerospace Limited has issued Pacific Aerospace Limited 
Mandatory Service Bulletin PACSB/XL/074, Issue 2, dated November 4, 
2014. 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 Proposed 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 proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 17 products of U.S. 
registry. We also estimate that it would take about 6 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $3,500 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $68,170, or $4,010 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 proposed 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 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.
    For the reasons discussed above, I certify this proposed 
regulation:
    (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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

Pacific Aerospace Limited: Docket No. FAA-2014-1002; Directorate 
Identifier 2014-CE-033-AD.

(a) Comments Due Date

    We must receive comments by January 22, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pacific Aerospace Limited Model 750XL 
airplanes, all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 34: Navigation.

(e) Reason

    This AD was prompted by 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 Pacific 
Aerospace Limited Model 750XL airplanes manufactured with instrument 
panels with only one attitude indicator. A second attitude indicator 
is required to operate under instrument flight rules (IFR). A 
reversionary attitude indicator reduces the probability of a single 
point failure, which could result in loss of control. We are issuing 
this proposed AD to install a reversionary attitude indicator before 
operating in IFR conditions.

 (f) Actions and Compliance

    Unless already done, before the next flight requiring instrument 
flight rules (IFR) after the effective date of this AD, install a 
second attitude indicator into the right hand instrument panel or 
enable the reversionary mode on a Sandel SN3500 electronic 
horizontal situation indicator (EHSI), if installed, whichever is 
applicable, following the ACCOMPLISHMENT INSTRUCTIONS in Pacific 
Aerospace Limited Mandatory Service Bulletin PACSB/XL/074, Issue 2, 
dated November 4, 2014.

[[Page 72566]]

(g) Other FAA AD Provisions

    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: Karl Schletzbaum, Aerospace Engineer, 901 
Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-
4146; fax: (816) 329-4090; email: karl.schletzbaum@faa.gov. 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.
