Airworthiness Directives; Superior Air Parts, Inc. (SAP), Cylinder Assemblies Part Numbers Series:
<p><strong>2007-04-19 R1 SUPERIOR AIR PARTS, INC.:</strong> Amendment 39-15005. Docket No. FAA-2006-25948; Directorate Identifier 2006-NE-32-AD.</p>
<p><strong>Airworthiness Directives; Superior Air Parts, Inc. (SAP), Cylinder Assemblies Part Numbers Series: SA47000L, SA47000S, SA52000, SA55000, SL32000W, SL32000WH, SL32006W, SL36000TW, SL36000W, and SL36006W </strong></p>
<p><strong>AGENCY:</strong> Federal Aviation Administration (FAA), Department of Transportation (DOT).</p>
<p><strong>ACTION:</strong> Final rule; request for comments.</p>
<p><strong>SUMMARY:</strong> <strong>The FAA is revising an existing airworthiness directive (AD)</strong> for certain SAP cylinder assemblies installed in Teledyne Continental Motors (TCM) 470, 520, and 550 series reciprocating engines, Lycoming Engines (LE) 320, 360, and 540 series reciprocating engines, Avco Lycoming (AL) 540 series reciprocating engines, and Superior Air Parts, Inc. (SAP) 360 series reciprocating engines. That AD currently requires removing from service certain SAP part numbered (P/N) cylinder assemblies installed in TCM, LE, and AL reciprocating engines. That AD also requires removing from service certain cylinder assemblies installed as original equipment in SAP reciprocating engines, or in certain overhauled or repaired SAP reciprocating engines.<br>
This AD continues to require those same actions. This AD results from comments from the Public on the existing AD. We are issuing this AD to prevent cylinder separation that can lead to engine failure, a possible engine compartment fire, and damage to the airplane.</p>
<p><strong>DATES:</strong> Effective May 7, 2007.</p>
<p><strong>Affected ADs </strong><br>
(b) <strong>This AD revises AD 2007-04-19.</strong></p>
<p><strong>Applicability </strong><br>
(c) This AD applies to Superior Air Parts, Inc. (SAP), cylinder assemblies, manufactured between April 2005 and November 2005, part numbers (P/Ns): SA47000L-A1, SA47000L-A20P, SA47000S-A1, SA47000S-A20P, SA47000S-A21P, SA52000-A1, SA52000-A20P, SA52000-A21P, SA52000-A22P, SA52000-A23P, SA55000-A1, and SA55000-A20P, installed in Teledyne Continental Motors (TCM) 470, 520, and 550 series reciprocating engines. These P/N cylinder assemblies may be installed in the TCM engine models listed in the following Table 1.</p>
