Airworthiness Directives; Textron Lycoming Reciprocating Engines

Action

Final Rule; Request For Comments.

Summary

This amendment supersedes emergency airworthiness directive (AD) 2000-18-53 that was sent previously to all known U.S. owners and operators of certain Textron Lycoming reciprocating engines. That action required before further flight after receipt of that emergency AD, replacement of the oil filter converter plate gasket or the converter plate kit. That action also required, within 10 hours time-in-service (TIS) or within 3 days after the effective date of that emergency AD, inspection of the oil filter base for signs of oil leakage and evidence of gasket extrusion. That action also required replacement of the converter plate gasket at intervals not to exceed 50 hours TIS since the last replacement of the gasket. This amendment requires the same replacements and inspection, and introduces the installation of an improved design gasket or converter plate kit as terminating action for the repetitive gasket replacements. The actions specified in this AD are intended to prevent complete loss of engine oil and subsequent seizing of the engine and possibility of fire, caused by oil leakage between the converter plate and accessory housing.

SUPPLEMENTARY INFORMATION: Back to Top

On September 5, 2000, the Federal Aviation Administration (FAA) issued Emergency airworthiness directive (AD) 2000-18-53, applicable to certain Textron Lycoming reciprocating engines. That AD requires the following:

  • For engines with more than 50 hours time-since-new (TSN), time-since-overhaul (TSO), or time-since-last replacement of the oil filter plate gasket, replacement of the oil filter converter plate gasket part number (P/N) LW-13388, or the converter plate kit P/N LW-13904.
  • For engines with fewer than 50 hours TSN, TSO, or time-since-last replacement of the oil filter converter plate gasket P/N LW-13388, or the converter plate kit P/N LW-13904, inspection of the oil filter base for signs of oil leakage and evidence of gasket extrusion.
  • Replacement of converter plate gasket P/N LW-13388 at intervals not to exceed 50 hours TIS since the last replacement of the gasket. The actions are required to be done in accordance with Textron Lycoming Mandatory Service Bulletin (MSB) 543A, dated August 30, 2000 and Textron Lycoming Service Instruction No. 1453, dated May 9, 1991.

That AD was prompted by reports of certain oil filter converter plate gaskets, P/N LW-13388, extruding from the seat of the oil filter converter plate. The protruding or swelling of the gasket allows oil to leak from between the plate and accessory housing. The actions specified in that AD are intended to prevent complete loss of engine oil and subsequent seizing of the engine and possible fire, caused by oil leakage between the converter plate and accessory housing.

Since emergency AD 2000-18-53 was issued, Textron Lycoming has issued a service bulletin supplement that relieves the requirements of MSB 543A and that eliminates the need for gasket replacement every 50 ours TSN, TSO, or time since the last replacement.

Manufacturer's Service Information Back to Top

The FAA has reviewed and approved the technical contents of the following Textron Lycoming Service Information:

  • MSB 543A, dated August 30, 2000, and SI No. 1453, dated May 9, 1991, that provide instructions for replacing the oil filter converter plate gasket P/N LW-13388, or the converter plate kit P/N LW-13904.
  • Supplement No. 1 to MSB 543A, dated October 4, 2000, that describes procedures for replacing the oil filter converter plate gasket P/N LW-13388, or the converter plate kit P/N LW-13904, with a new improved design.

FAA's Determination of an Unsafe Condition and Required Actions Back to Top

Since the unsafe condition described is likely to exist or develop on other engines of the same type design, the FAA issued emergency AD 2000-18-53 to prevent complete loss of engine oil and subsequent seizing of the engine and possible fire, caused by oil leakage between the converter plate and accessory housing. This AD requires for engines listed that were shipped from the factory between April 1, 1999 and October 4, 2000, and any engine listed that had the oil filter converter plate gasket replaced with gasket P/N LW-13388, and, any engine listed that had the oil filter converter plate replaced with converter plate kit P/N LW-13904, the following:

  • Before further flight after the effective date of this AD, for engines with more than 50 hours TSN or TSO, or time-since-last replacement of the oil filter plate gasket P/N LW-13388, replacement of the oil filter converter plate gasket or the converter plate kit P/N LW-13904.
  • Within 10 hours TIS or within 3 days after the effective date of this AD, whichever occurs earlier, for engines with fewer than 50 hours TSN, TSO, or time-since-last replacement of the oil filter converter plate gasket P/N LW-13388, or the converter plate kit P/N LW-13904, inspection of the oil filter base for signs of oil leakage and evidence of gasket extrusion.
  • Replacement of the converter plate gasket P/N LW-13388 at intervals not to exceed 50 hours TIS since the last replacement of the gasket.
  • As terminating action to the repetitive gasket replacement specified in this AD, replacement of the oil filter converter plate gasket or the oil filter converter plate with a converter plate kit, in accordance with Part II and Part III of Textron Lycoming Supplement 1 to MSB 543A, dated October 4, 2000.

The actions must be done in accordance with the service information described previously.

Immediate Adoption of This AD Back to Top

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 September 5, 2000 to all known U.S. owners and operators of the affected Textron Lycoming reciprocating engines. 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 Back to Top

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 for examination 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 action must submit a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket Number 2000-NE-36-AD.” The postcard will be date stamped and returned to the commenter.

Regulatory Analysis Back to Top

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 that must 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.
