AD 2016-12-12

We are superseding 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 required revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This new AD requires a new maintenance or inspection program revision to incorporate the revised Airworthiness Limitation Items (ALIs) and critical design configuration control limitations (CDCCLs). This new AD also adds certain airplanes to the applicability. This AD was prompted by the issuance of revised service information to update the Fuel ALIs and CDCCLs that address fuel tank system ignition sources. We are issuing 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.

Final rule.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008-05-18 R1, Amendment 39-16083 (74 FR 57402, November 6, 2009) (``AD 2008-05-18 R1''). AD 2008-05-18 R1 applied to certain Model F.27 Mark 050, 200, 300, 400, 500, 600, and 700 airplanes. The NPRM published in the Federal Register on January 4, 2016 (81 FR 38) (``the NPRM''). The NPRM was prompted by the issuance of revised service information to update the Fuel ALIs and CDCCLs that address fuel tank system ignition sources. The NPRM proposed to retain the requirements of AD 2008-05-18 R1, and require a new maintenance or inspection program revision to incorporate the revised ALIs and CDCCLs. The NPRM also proposed to add certain airplanes to the applicability. We are issuing 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 consequentloss of the airplane.
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 on all Model F.27 Mark 050, 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 Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2015-8137.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or

[[Page 39554]]

on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed, except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

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.

Costs of Compliance

We estimate that this AD affects 16 airplanes of U.S. registry.
The actions that are required by AD 2008-05-18 R1 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 takes about 1 work-hour per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD:
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.
