The FAA's summary their words, unchanged

We are superseding an existing airworthiness directive (AD) for certain Continental Motors, Inc. (CMI) models TSIO-520, TSIO-550-K, TSIOF-550K, and IO-550-N series reciprocating engines with new or rebuilt CMI starter adapters installed between January 1, 2011 and November 20, 2011. That AD currently requires replacing affected CMI starter adapters with starter adapters eligible for installation. This AD requires the same actions, but to an expanded population of reciprocating engines. This AD was prompted by two additional reports received of fractures in starter adapter gear shafts in certain additional part number (P/N) CMI starter adapters since we issued the existing AD. We are issuing this AD to prevent starter adapter gear shaft failure which could cause oil scavenge pump failure and engine in-flight shutdown.

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD) 2011-25-51, Amendment 39-16891, (76 FR 77382, December 13, 2011) and adding the following new AD: 2012-10-13 Continental Motors, Inc. (formerly Teledyne Continental Motors, formerly Continental): Amendment 39-17062; Docket No. FAA- 2011-1341; Directorate Identifier 2011-NE-41-AD. (a) Effective Date This AD is effective June 8, 2012. (b) Affected ADs This AD supersedes AD 2011-25-51, Amendment 39-16891 (76 FR 77382, December 13, 2011). (c) Applicability This AD applies to Continental Motors, Inc.(CMI) TSIO-520-B, BB, D, DB, E, EB, J, JB, K, KB, N, NB, UB, VB; TSIO-550-K; TSIOF- 550-K; IO-550-N (Turbo-normalized only; STC SE10589SC); with a starter adapter part number (P/N) 642085A17; 642085A18; 642085A19; 642085A20; 642085A22; 642085-1A1, R-642085A17; R-642085A18; R- 642085A19; or R-642085A22 installed, where the engine was manufactured before November 20, 2011, or, where a new or rebuilt starter adapter was installed before November 20, 2011. (d) Unsafe Condition This AD was prompted by two additional reports received of fractures in starter adapter gear shafts in certain additional P/N CMI starter adapters since we issued AD 2011-25-51 (76 FR 77382, December 13, 2011). We are issuing this AD to prevent starter adapter gear shaft failure which could cause oil scavenge pump failure and engine in-flight shutdown. (e) Compliance Comply with this AD within the compliance times specified, unless already done. (1) For starter adapters with less than 75 hours of total time- in-service (TIS) on the effective date of this AD, before further flight, replace the starter adapter with a starter adapter eligible for installation. (2) For starter adapters with between 75 and 100 hours of total TIS, inclusive on the effective date of this AD, within the next 10 hours of engine operation, or before exceeding 100 hours TIS, whichever occurs first, replace the starter adapter with a starter adapter eligible for installation. (3) For starter adapters with more than 100 hours of total TIS on the effective date of this AD, no further action is required. (f) Definition For the purpose of this AD, a starter adapter eligible for installation is: (1) A starter adapter with one of the P/Ns listed in this AD that has a vibro-peened manufacturer code below the ink stamped P/N on the starter adapter, or (2) A starter adapter with one of the P/Ns listed in this AD that has more than 100 hours total TIS. [[Page 30883]] (g) Alternative Methods of Compliance (AMOCs) The Manager, Atlanta Certification Office, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request.
