Airworthiness Directives; Boeing Model 747 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: This document corrects information that appeared in 
airworthiness directive (AD) 97-25-06, amendment 39-10230, that was 
published in the Federal Register on December 1, 1997 (62 FR 63622). 
The error resulted in an advertent omission in reference to acceptable 
replacement components. This AD, applicable to certain Boeing Model 747 
series airplanes, requires disconnection of the electrical connector to 
the scavenge pump of the center wing tank. This AD also requires a one-
time inspection to identify the part number of the electrical 
connector; and replacement of the pump with a new or serviceable pump, 
if necessary.

DATES: Effective December 16, 1997.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of December 16, 1997 (62 FR 63622, December 1, 1997).

FOR FURTHER INFORMATION CONTACT: Chris Hartonas, Aerospace Engineer, 
Systems and Equipment Branch, ANM-130S; or G. Michael Collins, 
Aerospace Engineer, Propulsion Branch, ANM-140S; FAA, Transport 
Airplane Directorate, Seattle Aircraft Certification Office, 1601 Lind 
Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-2864 or 
(425) 227-2689; fax (425) 227-1181.

SUPPLEMENTARY INFORMATION: On November 26, 1997, the FAA issued AD 97-
25-06, amendment 39-10230 (62 FR 63622, December 1, 1997). The AD 
requires disconnection of the electrical connector to the scavenge pump 
of the center wing tank; and a one-time inspection to identify the part 
number of the electrical connector, and replacement of the pump with a 
new pump, if necessary.
    As published, that AD contained an inadvertent omission in 
reference to acceptable replacement components. Throughout the preamble 
and in paragraph (a)(2) of the AD, the FAA required that a replacement 
scavenge pump be new. However, the FAA intended that a serviceable 
scavenge pump also be specified as an acceptable replacement component. 
In all other respects, the original document is correct.
    Since no other part of the regulatory information has been changed, 
the entire final rule is not being republished.
    The effective date of the AD remains December 16, 1997.


Sec. 39.13  [Corrected]

    On page 63623, in the second column, paragraph (a)(2) of AD 97-25-
06 is corrected to read as follows:
* * * * *
    (2) If an electrical connector having a part number other than the 
correct part number (as specified in the alert service bulletin) is 
installed: Prior to further flight, replace the scavenge pump with a 
new or serviceable scavenge pump with an electrical connector having 
the correct part number (as specified in the alert service bulletin) in 
accordance with the Accomplishment Instructions of the alert service 
bulletin.
