Start Preamble

AGENCY:

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

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require modification of the wiring distribution of the alternating current bus transfer power system and the right-hand and left-hand windshield anti-icing system, as necessary. This proposed AD results from a report of electrical sparks coming out of the flight deck from a panel behind the left seat. We are proposing this AD to prevent failure of the sliding window heating element(s), due to electrical overload, which could result in smoke and fire in the cockpit.

DATES:

We must receive comments on this proposed AD by June 26, 2006.

Discussion

The Civil Aviation Authority—The Netherlands (CAA-NL), which is the airworthiness authority for the Netherlands, notified us that an unsafe condition may exist on all Fokker Model F.28 Mark 0070 and 0100 airplanes. The CAA-NL advises that, a few minutes after takeoff, electrical sparks came out of the flight deck from a panel behind the left seat, on a Fokker Model F.28 Mark 0070 airplane. The flightcrew also noticed a strong electrical smell, but no visible smoke. Investigation revealed that several contacts of the J 4222A/P 4222B connector were burnt, creating a conductive path between the contacts of the left-hand (LH) windshield heating system and the LH sliding window heating system. The conductive path resulted in too high of a voltage on the LH sliding window, causing the overheat of the LH sliding window heating element. Failure of the sliding window heating element(s), due to electrical overload, if not corrected, could result in smoke and fire in the cockpit.

Relevant Service Information

Fokker Services B.V. has issued Fokker Service Bulletin SBF100-30-027, dated May 9, 2005; including Manual Change Notification—Maintenance Documentation MCNM F100-098, dated May 9, 2005; and including the drawings listed in the following table. (To conform to certain Office of the Federal Register requirements for incorporating these materials by reference, the table identifies the date of the service bulletin for undated drawings.)

The service bulletin describes procedures for modifying the wiring distribution of the alternating current bus transfer power system and the right-hand and left-hand windshield anti-icing system, as necessary. Specifically, the service bulletin describes modifying the following areas:

  • For Block A airplanes, in the passenger compartment ceiling through receptacle J 2953A/plug P 2953B, zone 267; in the flight compartment ceiling through receptacle J 4261A/plug P 4261B, zone 259; and in the flight compartment ceiling through receptacle J 4222A/plug P 4222B, zone 258.
  • For Block B airplanes, in the electrical power control (EPC) panel 1 through receptacle J 1566A/plug P 1566B, zone 244; and in EPC panel 3 through receptacle J 1590A/plug P 1590B, zone 242.
  • For Block C airplanes, in EPC panel 1 through receptacle J 1566A/plug P 1566B, zone 244.
  • For Block D airplanes, in EPC panel 3 through receptacle J 1590A/plug P 1590B, zone 242.
  • For Block E airplanes, in the passenger compartment ceiling through receptacle J 2953A/plug P 2953B, zone 267.

Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The CAA-NL mandated the service information and issued Dutch airworthiness directive NL-2005-009, dated June 30, 2005, to ensure the continued airworthiness of these airplanes in the Netherlands.

FAA's Determination and Requirements of the Proposed AD

These airplane models are manufactured in the Netherlands and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the CAA-NL has kept the FAA informed of the situation described above. We have examined the CAA-NL's findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States.

Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously.

Costs of Compliance

This proposed AD would affect about 10 airplanes of U.S. registry. The proposed actions would take about 3 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $2,400, or $240 per airplane.

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 Start Printed Page 30074is 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 have 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 that the 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); and

3. 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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
