Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2005-12-16, which applied to all Fokker Services B.V. Model F28 Mark 0100 airplanes. AD 2005-12-16 required an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. This new AD requires an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary. This AD also removes airplanes from the applicability. This AD was prompted by reports of smoke in the passenger compartment during ground operations and in-flight, and a determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly. We are issuing this AD to address the unsafe condition on these products.

DATES:

This AD is May 21, 2018.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 21, 2018.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of July 20, 2005 (70 FR 34642, June 15, 2005).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2005-12-16, Amendment 39-14132 (70 FR 34642, June 15, 2005) (“AD 2005-12-16”). AD 2005-12-16 applied to all Fokker Services B.V. Model F28 Mark 0100 airplanes. The NPRM published in the Federal Register on November 3, 2017 (82 FR 51172). The NPRM was prompted by reports of smoke in the passenger compartment during ground operations and in flight, and the determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly. The NPRM proposed to continue to require an inspection to determine the part number of the PSU panels for the PSU modification status, and corrective actions if applicable. The NPRM also proposed to require an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary. We are issuing this AD to detect and correct overheating of the PSU panel due to moisture ingress, which could result in smoke or fire in the passenger cabin.

The European Aviation Safety Agency (EASA), which is the Technical Agent Start Printed Page 16192for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0043, dated March 6, 2017 (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 0100 airplanes. The MCAI states:

Reports were received of burning smell and smoke in the passenger compartment during flight as a result of overheating of passenger service units (PSU). These were attributed to moisture ingress into the interface electrical connectors of an unsealed PSU panel.

This condition, if not detected and corrected, could lead to further incidents of smoke in the passenger compartment, possibly resulting in injury to occupants.

To address this potential unsafe condition, Grimes Aerospace Company, the PSU manufacturer (currently Honeywell) issued SB 10-1178-33-0040 and SB 10-1571-33-0041, and Fokker Services issued SBF100-25-097, to provide instructions for installation of improved sealing of the PSU and its interface electrical connectors. Subsequently, CAA-NL [Civil Aviation Authority—The Netherlands] issued AD (BLA) 2004-022 [which corresponds to FAA AD 2005-12-16] to require modification, cleaning and sealing of the affected PSU.

Since that [CAA-NL] AD was issued, following a new occurrence of burning smell and smoke in the passenger compartment during disembarking of the passengers, the investigation revealed that, on several aeroplanes, the modification instructions of Honeywell and Fokker Services (SB listed above) were not, or not correctly, implemented. Prompted by these findings, Fokker Services published SBF100-25-128, providing inspection instructions to detect non-accomplishment and any discrepancy with the original modification instructions.

For the reasons described above, this [EASA] AD retains the requirement of CAA-NL AD (BLA) 2004-022, which is superseded, and requires a one-time inspection [for discrepancies] of the PSU panels and their interface with the aeroplane, and, depending on findings, the accomplishment of applicable corrective action(s).

Discrepancies include incorrect application of the sealant on the PSU panels, uninstalled gaskets, inability to properly lock the connectors, and incorrectly applied sealant on the connectors. Corrective actions include restoring the sealing of the affected PSU panel, repairing the PSU panel, or installing a new PSU panel with a replaced receptacle, and installing gaskets; making sure the connecter can properly lock; and applying sealant on the connector.

The MCAI also revised the applicability by specifying certain line numbers and excluding airplanes on which certain modifications were done. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0906.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or 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 Fokker Service Bulletin SBF100-25-128, dated July 21, 2016. This service information describes procedures for inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and for incorrectly applied sealant on the connectors, and corrective actions.

Grimes Aerospace has issued Service Bulletin 10-1178-33-0040, dated October 15, 1993; Service Bulletin 10-1178-33-0040, Revision 1, dated March 25, 1996; and Service Bulletin 10-1571-33-0041, dated October 15, 1993. This service information describes procedures for inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions. This service information is distinct since it applies to different part numbers.

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 8 airplanes of U.S. registry.

The actions required by AD 2005-12-16, and retained in this AD take about 5 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $6 per product. Based on these figures, the estimated cost of the actions that are required by AD 2005-12-16 is $431 per product.

We also estimate that it would take about 13 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $8,840, or $1,105 per product.

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

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 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);Start Printed Page 16193

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.
