Related Airworthiness Directives
Supersedes 2002-17-53
Summary

This amendment supersedes emergency airworthiness directive (AD) 2002-17-53 that was sent previously to all known U.S. owners and operators of Textron Lycoming LTIO-540 and TIO-540 series engines, rated at 300 horsepower (HP) or higher. That action requires, before further flight, replacing certain serial-numbered crankshafts that were hammer forged with crankshafts that were press forged. That AD was prompted by reports of crankshaft failures in LTIO-540 and TIO-540 engines, rated at 300 HP or higher. This amendment expands the suspect population of engines to include engines with crankshafts that were manufactured between March 1997 and the present and all IO-540 engines with crankshafts that were manufactured between March 1997 and the present that have been modified by supplemental type certificate (STC) by installing a turbocharger system. The actions specified by this AD are intended to prevent failure of the crankshaft, which could result in total engine power loss, in-flight engine failure and possible forced landing.

Action Required

Final rule, request for comments.

(iv) If your crankshaft passes the material testing, the crankshaft may be returned to service.

Disposition of Crankshafts That Have Passed the Material Test

(e) A crankshaft that has passed the Lycoming material testing may be returned to service.

Disposition of Crankshafts That Have Failed the Material Test

(f) After the effective date of this AD, do not install in any engine, any crankshaft that has failed the material test.

Denial of Alternative Methods of Compliance

(g) An alternative method of compliance to perform material testing on crankshafts listed by SN in Table 2 of Lycoming MSB 552, dated August 16, 2002, will not be approved.

Special Flight Permits

(h) Special flight permits may be issued in accordance with 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirementsof this AD can be done.

Documents That Have Been Incorporated By Reference

(i) The actions must be done in accordance with the following Lycoming Mandatory Service Bulletin No. 552, dated August 16, 2002. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from Lycoming, 652 Oliver Street, Williamsport, PA 17701, U.S.A. Copies may be inspected at the FAA, New England Region, Office of the Regional Counsel, 12 New England Executive Park, Burlington, MA; or at the Office of the Federal Register, 800 North Capitol Street NW., suite 700, Washington, DC.

Effective Date

(j) This amendment becomes effective September 20, 2002.

Supplementary Information

On August 16, 2002, the FAA issued emergency AD 2002-17-53, applicable to Textron Lycoming LTIO-540 and TIO-540 series engines, rated at 300 HP or higher, to supersede emergency AD 2002-04-51 issued on February 11, 2002. AD 2002-17-53 requires replacing certain crankshafts that were manufactured using a hammer- forged process with crankshafts that were manufactured using a press- forged process. That action was prompted by reports of 17 crankshaft failures in LTIO-540 and TIO-540 engines, rated at 300 HP or higher, which were assembled with certain crankshafts that were manufactured using a hammer-forged process. The FAA is continuing the investigation into the cause of the crankshaft failures, and further regulatory action may follow. This action is prompted by an additional crankshaft failure that was outside the population of crankshafts covered by AD 2002-17-53. This AD requires the same replacement of certain crankshafts before further flight, and includes material testing of certain crankshafts manufactured between March 1997 and the present. This AD also expands the applicability to include all IO-540 engines with crankshafts that were manufactured between March 1997 and the present that have been modified by STC by installing a turbocharger system. This condition, if not corrected, could result in crankshaft failure, which could result in total engine power loss, in-flight engine failure and possible forced landing.

Manufacturer's Service Information

The FAA has reviewed the technical contents of Lycoming Mandatory Service Bulletin (MSB) No. 552, dated August 16, 2002, that provide tables of the affected engine and crankshaft serial numbers (SN's).

FAA's Determination of an Unsafe Condition and Required Actions

Since an unsafe condition has been identified that is likely to exist or develop on other Textron Lycoming LTIO-540 and TIO-540 engines, rated at 300 HP or higher, and on IO-540 engines that have been modified by STC by installing a turbocharger system with certain crankshafts installed, this AD requires removal of certain crankshafts before further flight and material testing of certain other crankshafts.

Immediate Adoption of This AD

Since it was found that immediate corrective action was required, notice and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately on August 16, 2002, to all known U.S. owners and operators of Textron Lycoming LTIO-540 and TIO- 540 engines, rated at 300 HP or higher. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to Section 39.13 of part 39 of the Federal Aviation Regulations (14 CFR part 39) to make it effective to all persons.

Comments Invited

Although this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate to the address specified under the caption ADDRESSES. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed.

Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket forexamination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket.

Commenters wishing the FAA to acknowledge receipt of their comments submitted in response to this notice must submit a self-addressed, stamped postcard on which the following statement is made: ``Comments to Docket No. 2002-NE-03-AD.'' The postcard will be date stamped and returned to the commenter.

Regulatory Analysis

This final rule does not have federalism implications, as defined in Executive Order 13132, because it 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. Accordingly, the FAA has not consulted with state authorities prior to publication of this final rule.

The FAA has determined that this regulation is an emergency regulation thatmust be issued immediately to correct an unsafe condition in aircraft, and is not a ``significant regulatory action'' under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption ADDRESSES.
