SUMMARY: This document publishes in the Federal Register an amendment 
adopting airworthiness directive (AD) 2009-15-16 that was sent 
previously to all known U.S. owners and operators of the McDonnell 
Douglas Corporation airplanes identified above by individual notices. 
This AD requires modifying the flight deck door. This AD is prompted by 
a report indicating that certain equipment of the flight deck door is 
defective. We are issuing this AD to prevent failure of this equipment, 
which could jeopardize flight safety.

those persons to whom it was made immediately effective by AD 2009-15-
16, which contained the requirements of this amendment.
    The Director of the Federal Register approved the incorporation by 
reference

FOR FURTHER INFORMATION CONTACT: Linda Haynes, Aerospace Engineer, 
COS--Certificate Management Branch, ACE-102A, FAA, Atlanta Aircraft 
Certification Office, 1701 Columbia Avenue, College Park, GA 30337; 
telephone 404-474-5525; fax 404-474-5606.

SUPPLEMENTARY INFORMATION: On July 15, 2009, we issued AD 2009-15-16, 
which applies to all McDonnell Douglas Model DC-9-10 series airplanes, 
DC-9-30 series airplanes, DC-9-81 (MD-81) airplanes, DC-9-82 (MD-82) 
airplanes, DC-9-83 (MD-83) airplanes, DC-9-87 (MD-87) airplanes, MD-88 
airplanes, and MD-90-30 airplanes.

Background

    We have received a report indicating that certain equipment of the 
flight deck door is defective. This condition, if not corrected, could 
result in failure of the equipment, which could jeopardize flight 
safety.

Relevant Service Information

    We reviewed TIMCO Service Bulletin TSB-88-52-045, Revision E, dated 
November 6, 2008. The service bulletin describes procedures for 
correcting the defect in the flight deck door.

FAA's Determination and Requirements of This AD

    Since the unsafe condition described is likely to exist or develop 
on other airplanes of the same type design, we issued AD 2009-15-16 to 
prevent failure of certain equipment of the flight deck door, which 
could jeopardize flight safety. The AD requires accomplishing the 
actions specified in the service information previously described.
    We have determined that notice and opportunity for prior public 
comment on AD 2009-15-16 were contrary to the public interest, and good 
cause existed to make the AD effective immediately by individual 
notices issued on July 15, 2009, to all known U.S. owners and operators 
of McDonnell Douglas Model DC-9-10 series airplanes, DC-9-30 series 
airplanes, DC-9-81 (MD-81) airplanes, DC-9-82 (MD-82) airplanes, DC-9-
83 (MD-83) airplanes, DC-9-87 (MD-87) airplanes, MD-88 airplanes, and 
MD-90-30 airplanes. These conditions still exist, and the AD is hereby 
published in the Federal Register as an amendment to section 39.13 of 
the Federal Aviation Regulations (14 CFR 39.13) to make it effective to 
all persons.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2010-0637; Directorate Identifier 2009-NM-062-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about 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.

Regulatory Findings

    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 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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
