Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

––––––––––––––––––––––––––––––––––

Summary:
We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V.
Model F28 Mark 1000, 2000, 3000, and 4000 airplanes. This AD requires contacting the FAA to
obtain instructions for addressing the unsafe condition on these products, and doing the actions
specified in those instructions. This AD was prompted by reports indicating that certain exit signs
have a hydrogen isotope that decays over time, causing the signs to lose their brightness. We are
issuing this AD to address the unsafe condition on these products.

Dates:
This AD becomes effective December 21, 2017.
We must receive comments on this AD by January 22, 2018.

Addresses:
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by
any of the following methods:
• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for
submitting comments.
• Fax: 202-493-2251.
• Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground
Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590.
• Hand Delivery: U.S. Department of Transportation, Docket Operations, M-30, West Building
Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC, between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Union, has issued EASA AD 2012-0239, dated November 9, 2012 (referred to
after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an
unsafe condition for certain Fokker Services B.V. Model F28 Mark 1000, 2000, 3000, and 4000
airplanes. The MCAI states:

A number of Fokker F28 aeroplanes have exit signs installed to locate the emergency
exits. A number of these signs are not electrically powered, but are self-illuminated by
means of a hydrogen isotope known as Tritium. As this isotope decays over time,
these signs will lose their brightness.

To remain compliant with regulations, Tritium exit signs should be replaced when
their brightness has deteriorated below accepted levels. The established service life for
the Tritium powered exit signs is 7 years. Currently, the Fokker F28 maintenance
program does not include a replacement task for signs containing Tritium.

This condition, if not corrected, could result in insufficiently bright exit signs, possibly
preventing safe evacuation during an emergency, which could result in injury to
occupants.

For the reasons described above, this [EASA] AD requires replacement of all Tritium
exit signs with photo-luminescent signs, which do not have an internal power source
like the Tritium powered exit signs. In addition, this [EASA] AD requires repetitive
maintenance tasks for the new photo-luminescent signs. [The EASA AD provides an
option to revise the airplane maintenance program.]

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and
locating Docket No. FAA-2017-1098.

FAA's Determination and Requirements of This 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. We are issuing this AD


2
because we evaluated all pertinent information and determined the unsafe condition exists and is
likely to exist or develop on other products of the same type design.

FAA's Determination of the Effective Date

Since there are currently no domestic operators of this product, we find good cause that notice
and opportunity for prior public comment are unnecessary. In addition, for the reason(s) stated above,
we find that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede
it by notice and opportunity for public comment. We invite you to send any written relevant data,
views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES
section. Include “Docket No. FAA-2017-1098; Product Identifier 2012-NM-216-AD” at the
beginning of your comments. We specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all comments received by the closing
date and may amend this AD based on those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including
any personal information you provide. We will also post a report summarizing each substantive
verbal contact we receive about this AD.

Costs of Compliance

Currently, there are no affected U.S.-registered airplanes. This AD requires contacting the FAA
to obtain instructions for addressing the unsafe condition, and doing the actions specified in those
instructions. Based on the actions specified in the MCAI AD, we are providing the following cost
estimates for an affected airplane that is placed on the U.S. Register in the future:

Estimated Costs
Action Labor cost Parts cost Cost per product
Replacement 1 work-hour × $85 per hour = $85 Unavailable $85
Inspection 1 work-hour × $85 per hour = $85 0 85
Maintenance program revision 1 work-hour × $85 per hour = $85 0 85

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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft
Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance
of ADs is normally a function of the Compliance and Airworthiness Division, but during this

3
transition period, the Executive Director has delegated the authority to issue ADs applicable to
transport category airplanes to the Director of the System Oversight Division.

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.
