Discussion

On May 9, 2007, we issued AD 2007– 10–16, Amendment 39–15057 (72 FR 27953, May 18, 2007). That AD required actions intended to address an unsafe condition on all British Aerospace Regional Aircraft Jetstream Model 3201 airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country.

Since we issued AD 2007–10–16, Amendment 39–15057 (72 FR 27953, May 18, 2007), BAE Systems (Operations) Ltd amended Jetstream Series 3200 Aircraft Maintenance Manual (AMM) Chapter 05–10–05, Airworthiness Limitations. Some life limits have been amended and new life limits introduced.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2014– 0044, dated February 24, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

The Jetstream Series 3200 Aircraft Maintenance Manual (AMM), includes Chapter 05–10–05 ‘‘Airworthiness Limitations, Description and Operation’’. The maintenance tasks and limitations contained in this chapter have been identified as mandatory actions for continued airworthiness and EASA issued AD 2007– 0074 to require operators to comply with those instructions.

Since that AD was issued, BAE Systems (Operations) Ltd amended Jetstream Series 3200 AMM Chapter 05–10–05 to introduce life limitations for the main landing gear radius rod mounting shaft assemblies and to incorporate wing structure inspections previously introduced through BAE Systems (Operations) Ltd Service Bulletin (SB) SB 51– JA020940. In addition, a new table was introduced to provide extended fatigue life limitations for structural items for aeroplanes entered into a life extension programme. Reference to BAE Systems (Operations) Ltd SB 32–JA981042 was updated from Revision 7 to Revision 8 to reflect increased life limits of the nose landing gear.

Failure to comply with the new and more restrictive instructions could result in an unsafe condition.

For the reasons described above, this EASA AD retains the requirements of EASA AD 2007–0074, which is superseded, and requires implementation of the maintenance requirements and/or airworthiness limitations as specified in Chapter 05–10–05 of the Jetstream Series 3200 AMM at Revision
29. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–0241.

Relevant Service Information

BAE Systems (Operations) Ltd has issued British Aerospace Jetstream 3200 Series Aircraft Maintenance Manual, Revision 29, dated December 15, 2012.


### 20833 Federal Register / Vol. 79, No. 71 / Monday, April 14, 2014 / Proposed Rules

The actions described in this AMM 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 14 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD of inserting the document into the Airworthiness Limitations section of the Instructions for Continued Airworthiness. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $1,190, or $85 per product.

We have no way of determining the cost to replace the life limited parts and to do the applicable maintenance tasks on each airplane. 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 [Amended]**

■ 2. The FAA amends § 39.13 by removing Amendment 39–15057 (72 FR 27953, May 18, 2007), and adding the following new AD:
British Aerospace Regional Aircraft: Docket No. FAA–2014–0241; Directorate Identifier 2014–CE–008–AD.

(a) Comments Due Date

We must receive comments by May 29,

**Airworthiness Directives; The Boeing Company** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. This proposed AD was prompted by reports of latently failed fuel shutoff valves discovered during fuel filter replacement. This proposed AD would require revising the maintenance or inspection program to include new airworthiness limitations. We are proposing this AD to detect and correct latent failures of the fuel shutoff valve to the engine, which could result in the inability to shut off fuel to the engine and, in case of certain engine fires, an uncontrollable fire that could lead to wing failure.

Discussion

We have received reports of latently failed fuel shutoff valves discovered during fuel filter replacement. Deficiencies in the valve actuator design have resulted in latent failures of the fuel shutoff valve to the engine. This condition, if not detected and corrected, could result in latent failures of the fuel shutoff valve to the engine, which could result in the inability to shut off fuel to the engine and, in case of certain engine fires, an uncontrollable fire that could lead to wing failure. FAA’s Determination
We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements

This proposed AD would require revising the maintenance or inspection program to include new airworthiness limitations. The airworthiness limitations would allow an operator to perform the operational check as either a maintenance action or a flightcrew action. The flightcrew or maintenance crew would monitor the engine spar valve lights for a few seconds immediately after moving the engine fuel condition levers. Flightcrews can perform this operational check while starting the engine or while shutting down the engine. Maintenance crews can do this operational check as a separate action that does not require actual starting of the engine.

This proposed AD would require revisions to certain operator maintenance documents to include these new inspections. Compliance with these inspections is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (i) of this proposed AD. The request should include a description of changes to the proposed inspections that will ensure the continued operational safety of the airplane.

Interim Action

We consider this proposed AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this proposed AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance

We estimate that this proposed AD affects 1,244 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:
