RIN 2120-AA64


Airworthiness Directives; Pratt & Whitney JT8D-1, -1A, -1B, -7, -
7A, -7B, -9, -9A, -11, -15, -15A, -17, -17A, -17R, -17AR, -209, -217, -
217A, -217C, and -219 Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, 
-15, -15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and -219 
turbofan engines. This proposed AD would require removing affected 
rotating parts overhauled by a certain repair vendor, and inspecting or 
replacing the parts as applicable. This proposed AD results from 
reports that certain JT8D critical life-limited rotating parts have 
been returned to service with cracks, corrosion pitting, or dimensions 
outside of manual limits. We are proposing this AD to prevent failure 
of critical life-limited rotating engine parts which could result in an 
uncontained engine failure and damage to the airplane.

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

SUPPLEMENTARY INFORMATION:

Docket Management System (DMS)

    We have implemented new procedures for maintaining AD dockets 
electronically. As of May 17, 2004, we post new AD actions on the DMS 
and assign a DMS docket number. We track each action and assign a 
corresponding Directorate identifier. The DMS docket No. is in the form 
``Docket No. FAA-200X-XXXXX.'' Each DMS docket also lists the 
Directorate identifier (``Old Docket Number'') as a cross-reference for 
searching purposes.

Comments Invited

    We invite you to submit any written relevant data, views, or 
arguments regarding this proposal. Send your comments to an address 
listed under ADDRESSES. Include ``Docket No. FAA-2004-19929; 
Directorate Identifier 2004-NE-15-AD'' in the subject line of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the proposed AD. We will

[[Page 78360]]

consider all comments received by the closing date and may amend the 
proposed AD in light of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this proposed AD. Using the search function of the 
DMS Web site, anyone can find and read the comments in any of our 
dockets, including the name of the individual who sent the comment (or 
signed the comment on behalf of an association, business, labor union, 
etc.). You may review the DOT's complete Privacy Act Statement in the 
Federal Register published on April 11, 2000 (65 FR 19477-78) or you

Examining the AD Docket

    You may examine the docket that contains the proposal, any comments 
received and any final disposition in person at the DMS Docket Offices 
between 9:00 a.m. and 5:00 p.m., Monday through Friday, except Federal 
holidays. The Docket Office (telephone (800) 647-5227) is located on 
the plaza level of the Department of Transportation Nassif Building at 
the street address stated in ADDRESSES. Comments will be available in 
the AD docket shortly after the DMS receives them.

Discussion

    During an investigation of two high pressure compressor disks from 
a repair vendor, PW found chips in the disks' protective coating. When 
PW removed the remainder of the coating, PW found cracks and corrosion 
pitting. Upon further investigation, PW found approximately 85% of the 
parts PW looked at from the same repair vendor were either cracked, had 
cracks emanating from bolt holes, were pitted, or improperly blended or 
machined. As a result, we issued Special Airworthiness Information 
Bulletin (SAIB) No. NE-02-08 on December 20, 2001 to provide additional 
information about this subject. SAIB No. NE-02-08 does not provide 
compliance time information. This condition, if not corrected, could 
result in an uncontained engine failure and damage to the airplane.

Relevant Service Information

    We have reviewed and approved the technical contents of PW Alert 
Service Bulletin (ASB) No. JT8D A6442, dated April 4, 2003, that 
describes procedures for removing the affected rotating parts, 
inspecting, overhauling, and returning the parts to service as 
applicable.

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. We are proposing this AD, which would require 
removing affected rotating parts overhauled by CADMAR Aerospace, Inc. 
and inspecting or replacing the parts as applicable. The proposed AD 
would require you to use the service information described previously 
to perform these actions.

Costs of Compliance

    We estimate that about 632 JT8D engines installed on airplanes of 
U.S. registry would be affected by this proposed AD. We estimate that 
158 engines will require access to the high pressure compressor outside 
of regularly scheduled maintenance, and will require 66 work hours per 
engine. The high pressure compressor section of the remaining 474 
engines will be inspected during regularly scheduled maintenance, and 
will therefore not require additional labor costs to inspect. The 
average labor rate is $65 per work hour. We estimate that half of the 
parts presently installed will require replacement, at a cost of 
approximately $6,730,750. Based on this information, we estimate the 
total cost of the proposed AD to U.S. operators to be $8,086,390.

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

    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. Would 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 summary of the costs to comply with this proposal and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.

List of Subjects in 14 CFR Part 39
