## Summary

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to the specified model helicopters. Table 1 of the AD has two part numbers that do not contain the “SC” prefix. This document adds the prefix and corrects that error. In all other respects, the original document remains the same.

## The airworthiness directive

### Correction of Regulatory Text

In the Federal Register document 2010-26565, filed October 21, 2010 and published on October 22, 2010 (75 FR 65222), on pages 65223 and 65224, Table 1 containing the part numbers 5084 and 5084-1 without the correct prefix “SC” is corrected to read as follows:

*Table 1*

| Component | Part No. (P/N) | Serial No. (S/N) |
| --- | --- | --- |
| Main rotor servo-control | P/N SC5083 | S/N 270M, 272M, 409M, 423M, 452M, or 1573. |
|  | P/N SC5083-1 | S/N 2902 through 2921, inclusive. |
|  | P/N SC5084 | S/N 30, 84, 104, 186, 438, 575, or 695. |
|  | P/N SC5084-1 | S/N 1462 through 1481, inclusive. |
| Tail rotor servo-control | P/N SC5072 | S/N 222M, 306M, or 309. |

### SUPPLEMENTARY INFORMATION

This AD, Amendment 39-16487 (75 FR 65222, October 22, 2010), requires replacing all servo-controls that are identified in the Applicability section, Table 1, of the AD.

As published, two part numbers shown in Table 1 on Federal Register page 65224, under item 2. of PART 39—AIRWORTHINESS DIRECTIVES section, are incorrect. The first incorrect part number (P/N) is “5084;” the correct P/N is “SC5084.” The second incorrect P/N is “5084-1;” the correct P/N is “SC5084-1.” The other P/Ns shown in Table 1 remain unchanged.

No other part of the preamble or regulatory information has been changed; therefore, only Table 1 of the final rule is being published in the Federal Register.

The effective date of this AD is November 26, 2010.
