Airworthiness Directives; Boeing Model 727 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects information in an existing 
airworthiness directive (AD), applicable to all Boeing Model 727 series 
airplanes, that currently requires inspections to detect cracking of 
the actuator rib fitting of the inboard door of the main landing gear 
(MLG); and various follow-on actions. This action corrects a reference 
to the amendment number of a previously-issued AD, which was superseded 
by AD 97-02-09.

DATES: Effective March 4, 1997.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 7, 1997 (62 FR 3988, January 28, 1997).

SUPPLEMENTARY INFORMATION: On January 14, 1997, the FAA issued AD 97-
02-09, amendment 39-9894 (62 FR 3988, January 28, 1997), which is 
applicable to all Boeing Model 727 series airplanes. That AD requires 
inspections to detect cracking of the actuator rib fitting of the 
inboard door of the main landing gear (MLG); and various follow-on 
actions. It was prompted by a report of a fractured rib fitting that 
had been reworked in accordance with one of two existing AD's. The 
actions specified by that AD are intended to prevent damage to the 
airplane caused by a failure of the landing gear to extend due to a 
fractured rib fitting.

Actions Since Issuance of the AD

    Since the issuance of AD 97-02-09, the FAA has become aware of the 
fact that certain references made to the amendment number of AD 93-01-
14, which appeared throughout the preamble of AD 96-02-09, its 
amendatory language, and the rule itself, were incorrect. The 
referenced amendment number that appeared in the published version of 
the AD was ``amendment 39-8368;'' however, the correct amendment number 
correlating to AD 93-01-14 is ``amendment 39-8468.''

Corrections Necessary to the Current AD

    The FAA has determined that it is appropriate to take action to 
correct AD 97-02-09 by revising all references to the amendment number 
of AD 93-01-14 to specify ``amendment 39-8468.'' Since AD 97-02-09 
supersedes AD 93-01-14, this correction is necessary in order to ensure 
that the proper amendment number is removed from the regulations as a 
result of this supersedure.
    Action is taken herein to correct the error and to correctly add 
the AD as an amendment to Sec. 39.13 of the Federal Aviation 
Regulations (14 CFR 39.13). The effective date of the rule remains 
March 4, 1997.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.


Sec. 39.13  [Corrected]

    In the issue of January 28, 1997, beginning in the third column of 
page 3989 and continuing to the first column of page 3990, the 
amendatory language, as well as the introductory text of the rule that 
specifies pertinent agency numbers and the airplane manufacturer, are 
corrected to read as follows:
* * * * *


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by removing amendment 39-6433 (55 FR 
601, January 8, 1990); and by removing amendment 39-8468 (58 FR 5574, 
January 22, 1993); and by adding a new airworthiness directive (AD), 
amendment 39-9894, to read as follows:

97-02-09 Boeing: Amendment 39-9894, Docket 95-NM-223-AD. Supersedes 
AD 90-02-19, amendment 39-6433; and supersedes AD 93-01-14, 
amendment 39-8468.

    Issued in Renton, Washington, on February 19, 1997.
