### 36014 Federal Register / Vol. 76, No. 119 / Tuesday, June 21, 2011 / Proposed Rules

Applicability

(c) This AD applies to Fokker Services B.V. Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes; Fokker Services B.V. Model F.28 Mark 0070, 0100, 1000, 2000, 3000, and 4000 airplanes; certificated in any category; all serial numbers.

Note 1: This AD requires revisions to certain operator maintenance documents to include a new Critical Design Configuration Control Limitation (CDCCL). Compliance with this CDCCL is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance (AMOC) according to paragraph (j)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.

Subject

(d) Air Transport Association (ATA) of America Code 28: Fuel.

Reason

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

[T]he Federal Aviation Administration (FAA) has published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) have published Interim Policy INT/POL/25/12. The review conducted by Fokker Services on the Fokker F27 and F28 type designs in response to these regulations revealed that, under certain failure conditions, a short circuit can develop in the fuel pilot valve solenoid or in the wiring to the solenoid. Such a short circuit may result in an ignition source in the wing tank vapour space.

This condition, if not corrected, could result in a wing fuel tank explosion and consequent loss of the aeroplane.
* * * * *
Compliance

(f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Installation of Fuses Packed in Jiffy Junctions

(g) Within 24 months after the effective date of this AD, re-work the wiring and install the fuses packed in jiffy junctions (i.e., crimped wire in-line junction device), in accordance with the Accomplishment Instructions of the applicable Fokker service bulletin identified in table 1 of this AD.

(h) Before further flight after doing the actions required by paragraph (g) of this AD: Revise the aircraft maintenance program by incorporating the CDCCL specified in paragraph 1.L.(1)(c) of the applicable Fokker service bulletins identified in table 1 of this AD.
No Alternative Actions, Intervals, and/or CDCCLs

(i) After accomplishing the revision required by paragraph (h) of this AD, no alternative CDCCLs may be used unless the CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j) of this AD.

FAA AD Differences

Note 2: This AD differs from the MCAI and/or service information as follows: Although European Aviation Safety Agency (EASA) Airworthiness Directive 2010–0195, dated September 29, 2010, specifies revising the maintenance program to include maintaining CDCCLs, this AD only requires the revision. Requiring a revision of the maintenance program, rather than requiring maintaining CDCCLs, requires operators to record AD compliance only at the time the revision is made. Maintaining CDCCLs specified in the airworthiness limitations must be complied with in accordance with 14 CFR 91.403(c). Other FAA AD Provisions (j) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance: The Manager, International Branch, ANM– 116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the International Branch, send it to ATTN: Tom Rodriguez, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone 425–227–1137; fax 425–227–1149. Information may be e-mailed
to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/ certificate holding district office. The AMOC approval letter must specifically reference this AD.

(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 FAAapproved 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. Related Information (k) Refer to MCAI EASA Airworthiness Directive 2010–0195, dated September 29, 2010, and the Fokker service bulletins identified in table 1 of this AD, for related information.

Persons interested in being placed on a mailing list for future NPRMs should contact the FAA’s Office of Rulemaking, (202) 267–9677, for a copy of Advisory Circular No. 11–2A, Notice of Proposed Rulemaking Distribution System, which describes the application procedure. The Proposal

The FAA is proposing an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to modify the Palm Beach International Airport Class C airspace area by raising the floor of Class C airspace to 1,600 feet MSL within an area overlying, and to the south of, the Palm Beach County Park Airport (see attached chart). Currently, the floor of Class C airspace in the vicinity of LNA is at 1,200 feet MSL. Raising the Class C floor as proposed would enhance safety by providing additional clearance between rotorcraft and fixed-wing aircraft entering the traffic pattern at LNA. This would allow fixed-wing aircraft entering the traffic pattern to safely overfly the existing helicopter patterns and also would allow LNA helicopter training activities to take place at higher altitudes. The boundaries would be depicted as subareas A, B, and C for clarity.

In addition, a minor correction is made to the geographic coordinates of LNA to reflect the current information in the FAA’s aeronautical database.

Class C airspace areas are published in paragraph 4,000 of FAA Order 7400.9U, dated August 18, 2010 and effective September 15, 2010, which is incorporated by reference in 14 CFR 71.1. The Class C airspace area modification proposed in this document would be published subsequently in the Order.

The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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.

This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies terminal airspace as required to preserve the safe and efficient flow of air traffic.
