SUMMARY: The FAA is correcting a typographical error in an existing
airworthiness directive (AD) that was published in the Federal Register
on September 15, 2005 (70 FR 54474). The error resulted in an
inadvertent reference to a nonexistent paragraph. This AD applies to
certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-
200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD
requires repetitive detailed and ultrasonic inspections of the thrust
links of the rear engine mounts for any crack or fracture and
corrective actions if necessary.
DATES: Effective September 30, 2005.
ADDRESSES: The AD docket contains the proposed AD, comments, and any
final disposition. You may examine the AD docket on the Internet at

SUPPLEMENTARY INFORMATION: On September 6, 2005, the FAA issued AD
2005-19-06, amendment 39-14271 (70 FR 54474, September 15, 2005), for
certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-
200C, 747-200F, 747-300, 747SR, and 747SP series airplanes; equipped
with Pratt & Whitney JT9D-3 and -7 series engines, except JT9D-70
engines. The AD requires repetitive detailed and ultrasonic inspections
of the thrust links of the rear engine mounts for any crack or fracture
and corrective actions if necessary.
As published, the requirements of paragraph (h)(1) of the AD
inadvertently reference doing the repetitive replacements ``* * * at
the applicable compliance time specified in paragraph (h)(1)(i) or
(h)(2)(ii) of this AD.'' However, there is no paragraph (h)(2)(ii) in
the AD. We have removed reference to paragraph (h)(2)(ii) and replaced
it with the correct reference to paragraph (h)(1)(ii).
No other part of the regulatory information has been changed;
therefore, the final rule is not republished in the Federal Register.
The effective date of this AD remains September 30, 2005.
Sec. 39.13 [Corrected]
0
In the Federal Register of September 15, 2005, on page 54476, in the
third column, paragraph (h)(1) of AD 2005-19-06 is corrected to read as
follows:
* * * * *
(1) Replace the cracked thrust link with a new or overhauled thrust
link in accordance with Part 2 of the service bulletin; except as
provided by paragraph (i) of this AD. Repeat the replacement at the
applicable compliance time specified in paragraph (h)(1)(i) or
(h)(1)(ii) of this AD.
* * * * *
Issued in Renton, Washington, on September 26, 2005.

Manager, Transport Airplane Directorate, Aircraft Certification
Service.
