[Federal Register: March 15, 2004 (Volume 69, Number 50)] [Rules and Regulations] [Page 12057-12060] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr15mr04-2] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. 2002-NE-31-AD; Amendment 39-13519; AD 2004-05-24] RIN 2120-AA64 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: 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 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 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: 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. 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. 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. 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.
