Federal Register Abstract

The FAA is superseding an existing airworthiness directive (AD) for Lycoming Engines (Formerly Textron Lycoming) AEIO-540, IO-540, LTIO-540, O-540, and TIO-540 series reciprocating engines. That action requires replacing certain zinc-plated crankshaft gear retaining bolts. This action retains that requirement, but expands the population of affected engines. In addition, this AD adds five additional kits for replacing the crankshaft gear retaining bolts. This AD results from notification from the Manufacturer of 161 engines not identified in the previous AD. This AD also results from approval of the five additional kits as alternative methods of compliance with AD 2002-23-06. We are issuing this AD to prevent loss of all engine power and possible forced landing.

Airworthiness Directives; Lycoming Engines (Formerly Textron 
Lycoming) AEIO-540, IO-540, LTIO-540, O-540, and TIO-540 Series 
Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Lycoming Engines (Formerly Textron Lycoming) AEIO-540, IO-540, 
LTIO-540, O-540, and TIO-540 series reciprocating engines. That action 
requires replacing certain zinc-plated crankshaft gear retaining bolts. 
This action retains that requirement, but expands the population of 
affected engines. In addition, this AD adds five additional kits for 
replacing the crankshaft gear retaining bolts. This AD results from 
notification from the Manufacturer of 161 engines not identified in the 
previous AD. This AD also results from approval of the five additional 
kits as alternative methods of compliance with AD 2002-23-06. We are 
issuing this AD to prevent loss of all engine power and possible forced 
landing.

DATES: Effective March 30, 2004. The Director of the Federal Register 
approved the incorporation by reference of Lycoming Service Bulletin 
554, dated September 30, 2002, on November 19, 2002 (67 FR 68932, 
November 14, 2002). The Director of the Federal Register approved the 
incorporation by reference of Lycoming Mandatory Service Bulletin No. 
554, Supplement 5, dated August 15, 2003, as of March 30, 2004.
    We must receive any comments on this AD by May 14, 2004.

SUPPLEMENTARY INFORMATION: On November 8, 2002, we issued AD 2002-23-
06, Amendment 39-12950 (67 FR 68932, November 14, 2002). That AD 
requires replacing the crankshaft gear retaining bolt:
    <bullet<ls-thn-eq> Before further flight on engines that have been 
overhauled or have had the gear retaining bolt replaced between 
November 27, 1996 and November 10, 1998, and that have not complied 
with emergency AD 2002-20-51 by using a bolt from the gear bolt 
replacement kit, 05K19987 and
    <bullet<ls-thn-eq> Within 10 hours time-in-service (TIS) or 7 days 
after the effective date of that AD, on engines that have complied with 
AD 2002-20-51, but did not install a bolt from gear bolt replacement 
kit, 05K19987, and
    <bullet<ls-thn-eq> Within 10 hours TIS or 7 days after the 
effective date of that AD, on engines that have been overhauled in the 
field, or that have had the gear retaining bolt replaced in the field 
between November 10, 1998, and the effective date of AD 2002-23-06 
(November 19, 2002).
    That AD was prompted by two failures of zinc-plated crankshaft gear 
retaining bolts, and a reassessment of the extent to which the suspect 
bolts may still be present in the field. That condition, if not 
corrected, could result in loss of all engine power and possible forced 
landing.

Actions Since AD 2002-23-06 Was Issued

    Since that AD was issued, Lycoming identified 161 additional 
engines by serial number (SN) that they might have assembled with a 
zinc-plated crankshaft gear retaining bolt, part number (P/N) STD-2209, 
during the initial assembly or during a subsequent rebuild or overhaul 
of the engine. Lycoming also developed five additional kits for other 
maintenance purposes that also contain replacement gear retaining 
bolts. We approved those kits as alternate methods of compliance with 
AD 2002-23-06, and incorporated those kits in this new AD. In addition, 
any bolt, STD-2209, installed by Lycoming after November 10, 1998, is 
cadmium plated and is not affected by AD 2002-23-06. This includes STD-
2209 bolts installed using Service Bulletin (SB) 554 in production, 
overhaul, or for any other reason. Lycoming has replaced bolt, STD-
2209, with bolt, STD-2247. This new bolt, STD-2247, is not affected by 
this AD.

Relevant Service Information

    We have reviewed and approved the technical contents of Lycoming SB 
No. 554, dated September 30, 2002, that describes procedures for 
replacing the existing crankshaft gear retaining bolt. We have also 
reviewed Lycoming Mandatory SB (MSB) No. 554, Supplement 5, dated 
August 15, 2003. That MSB provides lists of engine SNs, by engine 
model, of engines that were assembled with zinc-plated crankshaft gear 
retaining bolt, P/N STD-2209, during the initial assembly or during a

[[Page 12058]]

subsequent rebuild or overhaul of the engine by Lycoming.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other T/L AEIO-540, IO-540, O-540, LTIO-540, and TIO-540 
series reciprocating engines of the same type design. We are issuing 
this AD to prevent the loss of all engine power and possible forced 
landing. This AD requires replacing the crankshaft gear retaining bolt:
    <bullet<ls-thn-eq> Before further flight on engines that have been 
overhauled or have had the gear retaining bolt replaced between 
November 27, 1996 and November 10, 1998, by Lycoming, that have an 
engine serial number listed in Lycoming SB 554, and that have not 
complied with AD 2002-23-06.
    <bullet<ls-thn-eq> Before further flight on engines that have 
complied with AD 2002-23-06, but did not install a bolt from gear bolt 
replacement kits: 05K19987, 05K23325, 05K23326, 05K23327, 05K23335, or 
05K233367, or with a bolt that has a P/N other than P/N STD-2209.
    <bullet<ls-thn-eq> Before further flight on engines that have been 
overhauled in the field, between November 27, 1996 and the affective 
date of AD 2002-23-06 (November 19, 2002) that have not had the gear 
retaining bolt replaced with a bolt from kits: 05K19987, 05K23325, 
05K23326, 05K23327, 05K23335 or 05K23336, or with a bolt that has a P/N 
other than P/N STD-2209.
    <bullet<ls-thn-eq> Within 10 hours TIS or 7 days after the 
effective date of this AD, whichever occurs earlier, on engines listed 
by SN in Lycoming MSB No. 554, Supplement 5, dated August 15, 2003.
    You must use the service information described previously to 
perform the actions required by this AD.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

Changes to 14 CFR Part 39--Effect on the AD

    On July 10, 2002, we issued a new version of 14 CFR part 39 (67 FR 
47997, July 22, 2002), which governs our AD system. This regulation now 
includes material that relates to special flight permits, alternative 
methods of compliance, and altered products. This material previously 
was included in each individual AD. Since this material is included in 
14 CFR part 39, we will not include it in future AD actions.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment; however, we invite you to submit any written relevant data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``AD Docket No. 2002-NE-31-AD'' in the 
subject line of your comments. If you want us to acknowledge receipt of 
your mailed comments, send us a self-addressed, stamped postcard with 
the docket number written on it; we will date-stamp your postcard and 
mail it back to you. We specifically invite comments on the overall 
regulatory, economic, environmental, and energy aspects of the rule 
that might suggest a need to modify it. If a person contacts us 
verbally, and that contact relates to a substantive part of this AD, we 
will summarize the contact and place the summary in the docket. We will 
consider all comments received by the closing date and may amend the AD 
in light of those comments.
    We are reviewing the writing style we currently use in regulatory 
documents. We are interested in your comments on whether the style of 
this document is clear, and your suggestions to improve the clarity of 
our communications with you. You may get more information about plain

Regulatory Findings

    We have determined that 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 the 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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary by
