14 CFR Part 39

[Docket No. FAA-2004-19809; Directorate Identifier 2003-NM-284-AD]
RIN 2120-AA64


Airworthiness Directives; McDonnell Douglas Model DC-9-10 Series 
Airplanes; Model DC-9-20 Series Airplanes; Model DC-9-30 Series 
Airplanes; Model DC-9-40 Series Airplanes; Model DC-9-50 Series 
Airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and 
DC-9-87 (MD-87) Airplanes; and Model MD-88 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to certain SAFT America Inc., P/N 021929-
000 (McDonnell Douglas P/N 43B034LB02) and P/N 021904-000 (McDonnell 
Douglas P/N 43B034LB03) nickel cadmium batteries. The existing AD 
currently requires replacing all battery terminal screws, verifying 
that the battery contains design specification cells, and replacing the 
cells if the battery contains non-design specification cells. This 
proposed AD would require an inspection for certain nickel cadmium 
batteries and, if necessary, replacing battery terminal screws with new 
hex head bolts and adding shims. This proposed AD is prompted by a 
report of battery screws shearing off while under normal torque loads. 
We are proposing this AD to prevent internal shorting, arcing, and loss 
of emergency battery power due to failed battery screws, which could 
result in loss of emergency power to electrical flight components or 
other emergency power systems required in the event of loss of the 
aircraft primary power source.

DATES: We must receive comments on this proposed AD by January 28, 
2005.

SUPPLEMENTARY INFORMATION:

Docket Management System (DMS)

    The FAA has implemented new procedures for maintaining AD dockets 
electronically. As of May 17, 2004, new AD actions are posted on DMS 
and assigned a docket number. We track each action and assign a 
corresponding directorate identifier. The DMS AD docket number is in 
the form ``Docket No. FAA-2004-99999.'' The Transport Airplane 
Directorate identifier is in the form ``Directorate Identifier 2004-NM-
999-AD.'' Each DMS AD docket also lists the directorate identifier 
(``Old Docket Number'') as a cross-reference for searching purposes.

Discussion

    On September 14, 1998, we issued AD 98-20-17, amendment 39-10784 
(63 FR 50979, September 24, 1998), for certain SAFT America Inc., Part 
Number (P/N) 021929-000 (McDonnell Douglas P/N 43BO34LB02) and P/N 
021904-000 (McDonnell Douglas P/N 43BO34LB03) nickel cadmium batteries 
manufactured prior to December 1997 that are installed on, but not 
limited to McDonnell Douglas Model DC-9 and MD-80 airplanes, all serial 
numbers. (Since the issuance of that AD, we have re-identified certain 
McDonnell Douglas airplane model designations to correlate with the 
most recent type certificate data sheets for the affected models.) That 
AD requires replacing all battery terminal screws, verifying that the 
battery contains design specification cells, and replacing the cells if 
the battery contains non-design specification cells. That AD was 
prompted by an incident where the cell screws on one of the affected 
batteries were exposed to chloride, which caused the heads of some 
fasteners to shear off and eventually resulted in the battery 
exploding. We issued that AD to prevent that type of occurrence, which 
could result in loss of emergency power to electrical flight components 
or other emergency power systems required in the event of loss of the 
aircraft primary power source.

Actions Since Existing AD Was Issued

    Since we issued AD 98-20-17, we have received a report indicating 
that the main airplane battery screws that attach the link to 
individual battery cells were broken on a McDonnell Douglas Model DC-9-
83 (MD-83) airplane. Investigation revealed that the screws failed to 
meet manufacturing quality specifications and resulted in the screw 
heads shearing off while under normal torque loads. We have also 
determined that the SAFT nickel cadmium batteries specified in the 
applicability of AD 98-20-17 are installed only on the McDonnell 
Douglas airplane models specified in the applicability of this NPRM, 
and cannot be installed on any other airplane model.

Relevant Service Information

    We have reviewed Boeing Alert Service Bulletin (ASB) DC9-24A195, 
dated December 4, 2003. The ASB describes procedures for a visual 
inspection to determine if SAFT batteries having part number (P/N) 
021904-000 (Type 43BO34LB03) or P/N 021929-000 (Type 43BO34LB02) are 
installed in the airplane and an inspection to determine the code date 
of the battery. For battery codes prior to May 2003, the ASB describes 
procedures to modify the batteries. The modification consists of 
replacing the screws in the battery with new hex head bolts and 
installing a shim. Accomplishing the actions specified in the service 
information is intended to adequately address the unsafe condition.
    The ASB refers to SAFT Service Bulletin 01-02, Revision 2, dated 
August 11, 2003, as an additional source of service information for 
accomplishing the modification.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other products 
of this same type design. This proposed AD would supersede AD 98-20-17. 
This proposed AD would require accomplishing the actions specified in 
the service bulletin described previously.

Clarification of Applicability

    The Planning Information section of the ASB does not specify Model 
DC-9-11, -12, -13, and -15F airplanes in the effectivity of the ASB. 
The manufacturer has advised us that those certain models are not 
currently in service. Although those models may not currently be in 
service, we have no verification that any of those airplanes could not 
be returned to service at a future date. Therefore, the applicability 
of the proposed AD includes those models.
    Although the Planning Information section of the ASB does include a 
``DC-9-33'' airplane, the proposed AD does not specify that airplane 
model in the applicability. The manufacturer has advised that the 
listing of model was inadvertently included in the ASB. The 
manufacturer plans to issue an Information Notice to remove the ``DC-9-
33'' airplanes from the effectivity of the ASB.

Costs of Compliance

    There are about 1,828 airplanes worldwide of the affected design. 
This proposed AD would affect about 1,087 airplanes of U.S. registry.
    The proposed inspection to determine if certain SAFT batteries are 
installed would take about 1 work hour per airplane, at an average 
labor rate of $65 per work hour. Based on these figures, the estimated 
cost of the new actions specified in this proposed AD for U.S. 
operators is $70,655, or $65 per airplane.

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. 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.
    This rulemaking is promulgated under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, the FAA is charged 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 AD.

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. See the ADDRESSES section for a location 
to examine the regulatory evaluation.
