Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2000-17-03 that applies to all Fokker Services B.V. Model F.28 Mark 0100 airplanes. AD 2000-17-03 currently requires a one-time visual inspection and repetitive eddy current and dye penetrant inspections of the nose landing gear (NLG) main fitting to detect cracking of the NLG main fitting subassembly, and corrective actions if necessary. Since we issued AD 2000-17-03, we were advised that replacement of certain nose landing gear (NLG) units eliminates the need for repetitive inspections. This proposed AD would retain existing requirements, require installation a new part number NLG unit that would terminate the repetitive inspections, and add airplanes to the applicability. We are proposing this AD to prevent cracking of the NLG main fitting, which could lead to collapse of the NLG during takeoff and landing, and possible injury to the flight crew and passengers.

DATES:

We must receive comments on this proposed AD by April 14, 2014.

Discussion

On August 17, 2000, we issued AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000). AD 2000-17-03 requires actions intended to address an unsafe condition on Fokker Services B.V. Model F.28 Mark 0100 airplanes.

Since we issued AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000), we received a report of a NLG main fitting failure. The European Aviation Safety Agency Start Printed Page 11352(EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012-0002R1, dated March 30, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

In 1997, a report was received concerning a Fokker 100 (F28 Mark 0100) aeroplane, where during landing following nose wheel touch-down, the nose landing gear (NLG) broke off just below the pintle pins. Subsequent inspection by the affected operator of other aeroplanes in the fleet identified three more suspect NLG main fittings. Eddy current (EC) and/or dye penetrant inspections of these units later confirmed that cracks were present on the inner side of the downlock plunger support web. The total number of flight cycles (FC) accumulated by the cracked NLG main fittings at the time of detection were between 9,300 FC and 17,600 FC.

This condition, if not detected and corrected, could result in further incidents of NLG collapse, possibly resulting in damage to the aeroplane and/or injury to the occupants. To address this potential unsafe condition, (Civil Aviation Authority —Netherlands] CAA-NL issued AD (BLA) 1997-116 (currently at issue 2) to require repetitive inspections of the NLG main fitting and, depending on findings, rework or replacement of the NLG main fitting.

Since AD (BLA) 1997-116/2 was issued, it was determined that replacement of a Messier-Dowty (M-D, formerly Dowty Rotol) Part Number (P/N) 201071001 or P/N 201071002 NLG with, respectively, a P/N 201071003 or P/N 201071004 (which have a so-called `heavy weight' main fitting installed) or, respectively, with a P/N 201456001 or P/N 201461001 (which are so-called `heavy weight' NLG units) cancels the need for repetitive inspection and/or rework. The `heavy weight' main fitting was originally developed for an increased weight version (101,000 lbs. maximum take-off weight) of the Fokker 100, as well as for the Fokker 70 (F28 Mark 0070), and introduced on the production line.

M-D issued Service Bulletin (SB) F100-32-94 and Fokker Services issued SBF100-32-119, which provide instructions to install the P/N 201071003 or P/N 201071004 NLG on aeroplanes in service. In addition, Fokker Services issued optional SBF100-32-149 to introduce the P/N 201456001 or P/N 201461001 NLG units on aeroplanes in service.

In January 2010, a second NLG main fitting failure occurred. The results of the investigation showed that the fracture started from small fatigue cracks in the affected area. Prompted by this new occurrence, combined with the NLG certification methodology (safe life principle), EASA has decided that the existing terminating action, installation of a P/N 201071003 or P/N 201071004 NLG should be made mandatory. Alternatively, a P/N 201456001 or P/N 201461001 NLG can be installed, which meets the same requirement.

For the reasons described above, EASA issued AD 2012-0002, retaining the requirements of CAA-NL AD (BLA) 1997-116/2, which was superseded, and to require the replacement of all P/N 201071001 and P/N 201071002 NLG units with, respectively, P/N 201071003 and P/N 201071004 NLG units, or alternatively with, respectively, P/N 201456001 or P/N 201461001 NLG units.

Replacement of a NLG main fitting or of a NLG unit on an aeroplane constitutes terminating action for the repetitive inspections for that aeroplane.

EASA AD 2012-0002 also prohibits, after modification of an aeroplane, installation of a P/N 201071001 or P/N 201071002 NLG unit on that aeroplane.

* * * * *

This proposed AD expands the applicability to include all Fokker Services B.V. Model F.28 Mark 0100 airplanes. 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-2014-0062.

Relevant Service Information

Fokker Services B.V. has issued the following service bulletins:

  • Fokker Services B.V. Service Bulletin SBF 100-32-119, Revision 1, dated November 15, 2011, which refers to Messier-Dowty Service Bulletin F100-32-92, Revision 1, dated October 8, 1999, as an additional source of service information for accomplishing the inspections and rework of the NLG main fitting subassembly.
  • Fokker Services B.V. Service Bulletin Change Notification SBF 100-32-119/1, dated January 31, 2000.
  • Fokker Services B.V. Proforma Service Bulletin SBF 100-32-149, Revision 1, dated October 25, 2007, including Appendix 1, dated December 12, 2006.
  • Fokker Services B.V. Service Bulletin SBF 100-53-074, dated November 1, 1999.

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 the same type design.

In many FAA transport ADs, when the service information specifies to contact the manufacturer for further instructions if certain discrepancies are found, we typically include in the AD a requirement to accomplish the action using a method approved by either the FAA or the State of Design Authority (or its delegated agent).

We have recently been notified that certain laws in other countries do not allow such delegation of authority, but some countries do recognize design approval organizations. In addition, we have become aware that some U.S. operators have used repair instructions that were previously approved by a State of Design Authority or a Design Approval Holder (DAH) as a method of compliance with this provision in FAA ADs. Frequently, in these cases, the previously approved repair instructions come from the airplane structural repair manual or the DAH repair approval statements that were not specifically developed to address the unsafe condition corrected by the AD. Using repair instructions that were not specifically approved for a particular AD creates the potential for doing repairs that were not developed to address the unsafe condition identified by the MCAI AD, the FAA AD, or the applicable service information, which could result in the unsafe condition not being fully corrected.

To prevent the use of repairs that were not specifically developed to correct the unsafe condition, certain requirements of this proposed AD specify that the repair approval specifically refer to the FAA AD. This change is intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we use the phrase “its delegated agent, or the DAH with State of Design Authority design organization approval, as applicable” in this proposed AD to refer to a DAH authorized to approve certain required repairs for this proposed AD.

Explanation of Changes Made to the Existing AD

On July 10, 2002, the FAA issued a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the FAA's airworthiness directives system. The regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance (AMOCs). Because we have now included this material in 14 CFR part 39, only the office authorized Start Printed Page 11353to approve AMOCs is identified in each individual AD. Therefore, Notes 1 and 5 of AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000), are not included in this NPRM. We have also revised Note 2 of AD 2000-17-03 to lettered paragraph (h) in this NPRM (this change does not affect the intent of that Note) and removed Note 3 of that AD because that information does not apply to the new actions specified in this NPRM.

Costs of Compliance

We estimate that this proposed AD affects 4 airplanes of U.S. registry.

The actions that are required by AD 2000-17-03, Amendment 39-11876 (65 FR 52298, August 29, 2000), and retained in this proposed AD take about 2 work-hours 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 that were required by AD 2000-17-03 is $170 per product.

We also estimate that it would take about 8 work-hours 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 $525,000 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,102,720, or $526,680 per product.

We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this proposed AD.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.

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.
