[Docket No. 96-NM-146-AD; Amendment 39-9953; AD 97-05-09]
RIN 2120-AA64
Airworthiness Directives; Boeing Model 737 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: This document corrects a typographical error that appeared in
airworthiness directive (AD) 97-05-09 that was published in the Federal
Register on March 5, 1997 (62 FR 9925). The typographical error
resulted in the omission of a serial number of a power control unit
(PCU) from NOTE 2 of the AD. This AD is applicable to certain Boeing
Model 737 series airplanes and requires replacement of the flow
restrictors of the aileron and elevator PCU's with new flow
restrictors.
DATES: Effective April 9, 1997.
The incorporation by reference of certain publications listed in
the regulations was previously approved by the Director of the Federal
Register as of April 9, 1997 (62 FR 9925, March 5, 1997).
FOR FURTHER INFORMATION CONTACT: Don Kurle, Senior Engineer, Systems
and Equipment Branch, ANM-130S, FAA, Transport Airplane Directorate,
Seattle Aircraft Certification Office, 1601 Lind Avenue, SW., Renton,

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 97-05-09,
amendment 39-9953, applicable to certain Boeing Model 737 series
airplanes, was published in the Federal Register on March 5, 1997 (62
FR 9925). That AD requires replacement of the flow restrictors of the
aileron and elevator power control units (PCU) with new flow
restrictors.
As published, that AD contained a typographical error in NOTE 2,
which identifies PCU serial numbers that correspond to part number 65-
44761-21. The FAA inadvertently omitted serial number ``8549A'' from
NOTE 2 of the final rule. [This serial number was included in NOTE 2 of
the notice of proposed rulemaking (NPRM).]
Since no other part of the regulatory information has been changed,
the final rule is not being republished.
The effective date of the AD remains April 9, 1997.
Sec. 39.13 [Corrected]
On page 9928, in the first column, NOTE 2 of AD 97-05-09 is

P/N's 65-45180-29 and 65-44761-21 are serialized. PCU's subject to
the requirements of this AD may be more easily identified using
