ACTION:
 
Final rule; request for comments.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
The FAA is revising an existing airworthiness directive (AD), 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. That AD currently requires modifying the flight deck


door. This AD revises the applicability by removing certain airplanes. This AD was 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.


DATES:
 
This AD is effective August 5, 2010, to all persons except those persons to whom it was


made immediately effective by AD 2009-15-16, issued July 15, 2009, which contained the


requirements of this amendment.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in the AD as of August 5, 2010.


On July 6, 2010 (75 FR 38017, July 1, 2010), the Director of the Federal Register approved the


incorporation by reference of a certain other publication listed in the AD.


We must receive any comments on this AD by September 20, 2010.

SUPPLEMENTARY INFORMATION:


Discussion


On June 18, 2010, we issued AD 2009-15-16, Amendment 39-16345 (75 FR 38017, July 1,


2010). That AD applies to all McDonnell Douglas Corporation 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. That AD requires


modifying the flight deck door. That AD was prompted by a report indicating that certain equipment


of the flight deck door is defective. The actions specified in that AD are intended to prevent failure of


this equipment, which could jeopardize flight safety.


Actions Since AD Was Issued


Since we issued that AD, we have learned that certain airplanes were incorrectly included in the


applicability. The only airplanes subject to the identified unsafe condition are those equipped with


flight deck doors installed in accordance with Supplemental Type Certificate (STC) ST02463AT.


Relevant Service Information


AD 2009-15-16 referred to TIMCO Service Bulletin TSB-88-52-045, Revision E, dated


November 6, 2008, as the appropriate source of service information for the required modification.


TIMCO has since revised the service bulletin. Revision G, dated December 8, 2009, changes Part II.,


''Approval Basis,'' by referring to STC ST02463AT. The procedures specified in Revision G of this


service bulletin are unchanged from those in Revision E.


FAA's Determination and Requirements of this AD


The unsafe condition described previously is likely to exist or develop on other airplanes of these


same type designs. For this reason, we are issuing this AD to revise AD 2009-15-16. This new AD


retains the requirements of the existing AD, and includes the following changes:

SUPPLEMENTARY INFORMATION:


Discussion


On June 18, 2010, we issued AD 2009-15-16, Amendment 39-16345 (75 FR 38017, July 1,


2010). That AD applies to all McDonnell Douglas Corporation 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. That AD requires


modifying the flight deck door. That AD was prompted by a report indicating that certain equipment


of the flight deck door is defective. The actions specified in that AD are intended to prevent failure of


this equipment, which could jeopardize flight safety.


Actions Since AD Was Issued


Since we issued that AD, we have learned that certain airplanes were incorrectly included in the


applicability. The only airplanes subject to the identified unsafe condition are those equipped with


flight deck doors installed in accordance with Supplemental Type Certificate (STC) ST02463AT.


Relevant Service Information


AD 2009-15-16 referred to TIMCO Service Bulletin TSB-88-52-045, Revision E, dated


November 6, 2008, as the appropriate source of service information for the required modification.


TIMCO has since revised the service bulletin. Revision G, dated December 8, 2009, changes Part II.,


''Approval Basis,'' by referring to STC ST02463AT. The procedures specified in Revision G of this


service bulletin are unchanged from those in Revision E.


FAA's Determination and Requirements of this AD


The unsafe condition described previously is likely to exist or develop on other airplanes of these


same type designs. For this reason, we are issuing this AD to revise AD 2009-15-16. This new AD


retains the requirements of the existing AD, and includes the following changes:
