That AD applies to Teledyne Continental Motors O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 series reciprocating engines. The two references to the AD number are incorrect due to a software problem with the automated AD number assignment system. This document corrects those references. In all other respects, the original document remains the same. ## The airworthiness directive On page 48141, in the second column, in the third line below 14 CFR Part 39, “AD 2009-19-06” is corrected to read “AD 2009-19-07”. On page 48142, in the third column, in the eighth line below PART 39-AIRWORTHINESS DIRECTIVES, “2009-19-06 Teledyne Continental Motors” is corrected to read “2009-19-07 Teledyne Continental Motors”. ## Rule preamble ### Dates Effective October 7, 2009. ### For further information contact Anthony Holton, Engineer, Propulsion, Atlanta Aircraft Certification Office, FAA, Small Airplane Directorate, 1701 Columbia Avenue, College Park, Georgia 30337; e-mail: anthony.holton@faa.gov; telephone: (404) 474-5567; fax: (404) 474-5606. ### SUPPLEMENTARY INFORMATION On September 22, 2009, we published a final rule AD, FR Doc. E9-22287, in the Federal Register (74 FR 48141). That AD applies to Teledyne Continental Motors O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 series reciprocating engines. We need to make the following correction: ## Affected data sheets (6) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS E8CE](https://openairdocs.org/tcds/E8CE): Continental Aerospace Technologies, Inc.; names 26 of 31 models: TSIO-520-BB, TSIO-520-B, TSIO-520-P, TSIO-520-R, TSIO-520-AF, TSIO-520-M, TSIO-520-J, TSIO-520-D… - [TCDS E5CE](https://openairdocs.org/tcds/E5CE): Continental Aerospace Technologies, Inc.; names 14 of 18 models: IO-520-BA, IO-520-A, IO-520-B, IO-520-C, IO-520-L, IO-520-J, IO-520-BB, IO-520-MB… - [TCDS E3SO](https://openairdocs.org/tcds/E3SO): Continental Aerospace Technologies, Inc.; names 13 of 20 models: IO-550-F, IOF-550-B, IOF-550-E, IOF-550-L, IOF-550-D, IO-550-L, IOF-550-C, IO-550-B… - [TCDS 3E1](https://openairdocs.org/tcds/3E1): Continental Aerospace Technologies, Inc.; names 11 of 19 models: IO-470-H, IO-470-D, IO-470-M, IO-470-L, IO-470-S, IO-470-V, IO-470-U, IO-470-N… - [TCDS E-273](https://openairdocs.org/tcds/E-273): Continental Aerospace Technologies, Inc.; names 8 of 21 models: O-470-R, IO-470-C, O-470-L, O-470-G, O-470-U, O-470-S, O-470-M, O-470-K - [TCDS 3E3](https://openairdocs.org/tcds/3E3): Continental Aerospace Technologies, Inc.; names 3 of 3 models: TSIO-470-C, TSIO-470-B, TSIO-470-D ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 35,836 (0 by airframe model, 35,836 by engine model) - Makers: Cessna 21,553, Beech 10,033, Cirrus Design 1,270, Raytheon 595, Bellanca 581, Mooney 377, Hawker Beechcraft 209, Piper 190, Textron 132, Lancair 124 Models with the most aircraft: - [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series): 12,779 aircraft (engine model) - [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series): 9,486 aircraft (engine model) - [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series): 4,499 aircraft (engine model) - [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series): 4,064 aircraft (engine model) - [Continental IO-550 series](https://openairdocs.org/engine/continental-io-550-series): 3,077 aircraft (engine model) - [Continental IO-550-B](https://openairdocs.org/engine/continental-io-550-b): 373 aircraft (engine model) - [Continental IO-470 series](https://openairdocs.org/engine/continental-io-470-series): 225 aircraft (engine model) - [Continental IO-550-C](https://openairdocs.org/engine/continental-io-550-c): 199 aircraft (engine model) - [Continental O-470R](https://openairdocs.org/engine/continental-o-470r): 107 aircraft (engine model) - [Continental IO-520-D](https://openairdocs.org/engine/continental-io-520-d): 95 aircraft (engine model) - [Continental IO-520-F](https://openairdocs.org/engine/continental-io-520-f): 80 aircraft (engine model) - [Continental TSI0-470-B](https://openairdocs.org/engine/continental-tsi0-470-b): 75 aircraft (engine model) - [Continental TSIO-520-M](https://openairdocs.org/engine/continental-tsio-520-m): 60 aircraft (engine model) - [Continental O-470-U](https://openairdocs.org/engine/continental-o-470-u): 56 aircraft (engine model) - [Continental TSIO-520-NB](https://openairdocs.org/engine/continental-tsio-520-nb): 52 aircraft (engine model) - [TCM Cont TSIO-520 series](https://openairdocs.org/engine/tcm-cont-tsio-520-series): 49 aircraft (engine model) - [Lycoming IO-520 series](https://openairdocs.org/engine/lycoming-io-520-series): 49 aircraft (engine model) - [Continental IO-520-BB](https://openairdocs.org/engine/continental-io-520-bb): 44 aircraft (engine model) - [Continental IO-550-D](https://openairdocs.org/engine/continental-io-550-d): 36 aircraft (engine model) - [Continental TSIO-520-UB](https://openairdocs.org/engine/continental-tsio-520-ub): 27 aircraft (engine model) All 71 models: https://openairdocs.org/ad/2009-19-07/models.md Every aircraft: https://openairdocs.org/ad/2009-19-07/aircraft.md No proposed rule in this release led to it.
