# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports that cracks can occur in a frame of the tail section on certain airplanes. This proposed AD would require a one-time detailed inspection of the oblique frame 67-2 for any cracking, and repair if necessary. We are proposing this AD to detect and correct such cracking, which could lead to failure of the oblique frame 67-2, and consequent loss of the structural integrity of the tail section.

# DATES:

We must receive comments on this proposed AD by March 9, 2015.

## Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0039, dated February 20, 2014 (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.28 Mark 0070 and 0100 airplanes. The MCAI states:

Service experience has shown that cracks can occur in oblique frame 67-2 in the tail section on aeroplanes with more than 29 000 flight cycles (FC).

This condition, if not detected and corrected, can result in an exponential crack growth rate, possibly leading to failure of the oblique frame 67-2 over a certain length and consequent loss of the structural integrity of the tail section of the aeroplane.

For the reasons described above, this [EASA] AD requires a one-time [detailed] inspection of the oblique frame 67-2 for cracks and, depending on findings, accomplishment of a repair.

Repetitive inspections are planned to be incorporated into a revision of Fokker Services Report SE-623, which is part of the Airworthiness Limitations Section of the Instructions for Continued Airworthiness, for which a separate [EASA] AD is expected to be published.

Fokker Services All Operators Message AOF100.187#02 provides additional information concerning the subject addressed by this [EASA] AD.

                    You may examine the MCAI in the AD docket on the Internet at                     *http://www.regulations.gov*                     by searching for                           ( print page 3501)                        and locating Docket No. FAA-2014-1048.                

## Related Service Information

Fokker Services B.V. has issued Service Bulletin SBF100-53-124, dated January 23, 2014; and Service Bulletin SBF100-53-125, Revision 1, dated February 13, 2014. The service information describes procedures for a one-time detailed inspection of the oblique frame 67-2 for any cracking, and repair if necessary. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

## 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 these same type designs.

## Costs of Compliance

We estimate that this proposed AD affects 8 airplanes 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. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $680, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 12 work-hours and require parts costing $0, for a cost of $1,020 per product. We have no way of determining the number of aircraft that might need this action.

## 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.

## 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 

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): 

**Fokker Services B.V.:**                         Docket No. FAA-2014-1048; Directorate Identifier 2014-NM-055-AD.                    

## (a) Comments Due Date

We must receive comments by March 9, 2015.

## (b) Affected ADs

None.

## (c) Applicability

This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.

## (d) Subject

Air Transport Association (ATA) of America Code 53, Fuselage.

## (e) Reason

This AD was prompted by reports that cracks can occur in oblique frame 67-2 in the tail section on certain airplanes. We are issuing this AD to detect and correct such cracking, which could lead to failure of the oblique frame 67-2, and consequent loss of the structural integrity of the tail section.

## (f) Compliance

Comply with this AD within the compliance times specified, unless already done.

## (g) Inspection and Repair

For airplanes that have accumulated more than 29,000 total flight cycles since the airplane's first flight as of the effective date of this AD: Within 500 flight cycles or 12 months after the effective date of this AD, whichever occurs first, do a one-time detailed inspection of the oblique frame 67-2 for any cracking, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-53-124, dated January 23, 2014. For the purposes of this AD, a detailed inspection is an intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.

## (h) Corrective Action

If any cracking is found during the inspection required by paragraph (g) of this AD, before further flight, repair the oblique frame 67-2, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-53-125, Revision 1, dated February 13, 2014.

##  (i) Other FAA AD Provisions
