AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2008-05-18 R1 for certain Fokker Services B.V. Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. Since we issued AD 2008-05-18 R1, revised service information has been issued to update the Fuel Airworthiness Limitations Items (ALIs) and critical design configuration control limitations (CDCCLs) that address fuel tank system ignition sources. This proposed AD would require a new maintenance or inspection program revision to incorporate the revised ALIs and CDCCLs. This proposed AD would add certain airplanes to the applicability. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Discussion

On October 26, 2009, we issued AD 2008-05-18 R1, Amendment 39-16083 (74 FR 57402, November 6, 2009) for certain Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems.

Since we issued AD 2008-05-18 R1, Amendment 39-16083 (74 FR 57402, November 6, 2009), revised service information has been issued to update the fuel ALIs and CDCCLs. The revised service information applies to all Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0029, dated February 24, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. The MCAI states:

* * * [T]he FAA published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12. The review conducted by Fokker Services on the Fokker F27 design in response to these regulations identified a number of Fuel Airworthiness Limitation Items (ALI) and Critical Design Configuration Control Limitations (CDCCL) items to prevent the development of unsafe conditions within the fuel system.

To introduce these Fuel ALI and CDCCL items, Fokker Services published Service Bulletin (SB) F27/28-070. Consequently, EASA issued AD 2006-0207, requiring the implementation of these Fuel ALI and CDCCL items. That [EASA] AD was later revised to make reference to SBF27-28-070R1 and to specify that the use of later SB revisions was acceptable.

In 2014, Fokker Services issued Revision 2 of SBF27-28-070 to update the Fuel ALI and CDCCL items and to consolidate Fuel ALI and CDCCL items contained in a number of other SBs. Consequently, EASA issued AD 2014-0105, superseding AD 2006-0207R1 and requiring the implementation of the updated Fuel ALI and CDCCL items.

Since that [EASA] AD was issued, Fokker Services issued Revision 3 of SBF27-28-070, primarily to introduce 2 additional CDCCL items.

For the reason described above, this [EASA] AD retains the requirements of EASA AD 2014-0105, which is superseded, and requires implementation of the updated Fuel ALI and CDCCL items.

More information on this subject can be found in Fokker Services All Operators Message AOF27.043#05.

The unsafe condition is the potential of ignition sources inside fuel tanks. Such ignition sources, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. You may examine the MCAI in the AD docket on the Start Printed Page 39Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2015-8137.

Related Service Information Under 1 CFR Part 51

Fokker Services B.V. has issued Service Bulletin SBF27-28-070, Revision 3, dated December 11, 2014. The service information describes tasks for revising the maintenance or inspection program to update the fuel ALIs and CDCCLs that address fuel tank system ignition sources. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

This proposed AD would require implementation of certain maintenance requirements and airworthiness limitations. This proposed AD would also require accomplishing the actions specified in the service information described previously.

This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections) and CDCCLs. Compliance with these actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these actions, 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 according to the procedures specified in paragraph (m)(1) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.

Notwithstanding any other maintenance or operational requirements, components that have been identified as airworthy or installed on the affected airplanes before accomplishing the revision of the airplane maintenance or inspection program, or before accomplishing the revision of the Airworthiness Limitation Section (ALS) of the Instructions for Continued Airworthiness, as specified in this AD, do not need to be reworked in accordance with the CDCCLs. However, once the airplane maintenance or inspection program, or ALS, has been revised as required by this AD, future maintenance actions on these components must be done in accordance with the CDCCLs

Costs of Compliance

We estimate that this proposed AD affects 16 airplanes of U.S. registry.

The actions that are required by AD 2008-05-18 R1, Amendment 39-16083 (74 FR 57402, November 6, 2009), take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the actions required by AD 2008-05-18 R1 is $85 per product.

We also estimate that it would take about 1 work-hour per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,360, or $85 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 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.
