# 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.

## 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.

# List of Subjects in 14 CFR Part 39

      - Air transportation
      - Aircraft
      - Aviation safety
      - Incorporation by reference
      - Safety

## 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

1. The authority citation for part 39 continues to read as follows: 

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

§ 39.13 

2. The FAA amends § 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.                              ( print 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.
