The FAA's summary their words, unchanged

We are adopting a new airworthiness directive (AD) for certain models of Lycoming Engines reciprocating engines. This AD requires an inspection of connecting rods and replacement of affected connecting rod small end bushings. This AD was prompted by several reports of connecting rod failures resulting in uncontained engine failure and in- flight shutdowns (IFSDs). We are issuing this AD to address the unsafe condition on these products.

The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2017-16-11 Lycoming Engines Reciprocating Engines: (Type Certificate previously held by Textron Lycoming Division, AVCO Corporation): Amendment 39-18988; Docket No. FAA-2017-0788; Product Identifier 2017-NE-27-AD. (a) Effective Date This AD is effective August 15, 2017. (b) Affected ADs None. (c) Applicability This AD applies to: (1) All Lycoming Engines reciprocating engines listed in Table 1 of Lycoming Engines Mandatory Service Bulletin (MSB) No. 632B, dated August 4, 2017, and (2) all Lycoming Engines reciprocating engines that were overhauled or repaired using any replacement part listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017, which was shipped from Lycoming Engines during the dates listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017. (d) Subject Joint Aircraft System Component (JASC) Code 8520, Reciprocating Engine Power Section. (e) Unsafe Condition This AD was prompted by several reports of connecting rod failures resulting in uncontained engine failure and in-flight shutdowns (IFSDs). We are issuing this AD to prevent connecting rod failure. The unsafe condition, if not corrected, could result in uncontained engine failure, total engine power loss, IFSD, and possible loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) For all affected engines, within 10 operating hours after the effective date of this AD, inspect all affected connecting rods as specified in Lycoming Engines MSB No. 632B, dated August 4, 2017, except for the instruction to complete the online survey and the instruction to review your inventory. (2) Replace all connecting rods that fail the inspection required by paragraph (g)(1) of this AD with parts eligible for installation. (h) Installation Prohibition After the effective date of this AD: (1) Do not install any Lycoming Engines reciprocating engine that was overhauled or repaired using any replacement part listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017, which was shipped from Lycoming Engines during the dates listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017, and (2) do not install any part listed in Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017 into any Lycoming Engines reciprocating engine. (i) Credit for Previous Actions You may take credit for the actions required by paragraph (g) of this AD if you performed those actions before the effective date of this AD using Lycoming Engines MSB No. 632A, dated July 23, 2017 or earlier versions.
