14 CFR Part 39

[Docket No. FAA-2005-22748; Directorate Identifier 2005-NM-127-AD]
RIN 2120-AA64


Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 
Airplanes

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 certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This 
proposed AD would require modifying the passenger door and installing 
new placards. This proposed AD results from reports of the airstairs-
type passenger door opening during flight. We are proposing this AD to 
prevent rapid decompression of the airplane, or ejection of a passenger 
or crew member out the door during flight.

DATES: We must receive comments on this proposed AD by November 21, 
2005.

ADDRESSES: Use one of the following addresses to submit comments on 
this proposed AD.
     DOT Docket Web site: Go to http://dms.dot.gov and follow 
the instructions for sending your comments electronically.
     Government-wide rulemaking Web site: Go to http://www.regulations.gov and follow the instructions for sending your 
comments electronically.

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 certain Fokker Model F.28 Mark 0070 and 
0100 airplanes. The CAA-NL advises of several cases of the airstairs-
type passenger door opening during flight on a Model F.28 Mark 0100 
airplane. Investigators in all cases concluded that the incidents were 
not caused by defects in the design of the operating mechanism or the 
warning system, but probably resulted from incorrect use of the locking 
handle. Opening of the passenger door during flight could result in 
rapid decompression of the airplane, or a passenger or crew member 
being ejected out the door during flight.
    The passenger door operating mechanism and warning system is the 
same on both Model F.28 Mark 0100 and 0700 airplanes. Therefore, both 
of these airplane models are subject to the identified unsafe 
condition.

    The service bulletin describes procedures for modifying the 
passenger door. The modification involves installing additional door 
status indicators above the door, including relays and a flasher, a 
door status LED indicator, a circuit breaker, and electrical wiring; 
and making a cut-out in the cover above the passenger door. The service 
bulletin also describes procedures for installing improved placards at 
the handle and on the door. 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 2002-057, dated April 29, 2002, 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

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed 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

[[Page 61241]]

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.
