Airworthiness Directives; Boeing Model 737 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects information in an existing 
airworthiness directive (AD) that applies to all Boeing Model 737 
series airplanes. That AD supersedes AD 99-05-15, amendment 39-11063, 
to require revising the FAA-approved Airplane Flight Manual (AFM) 
procedure in the existing AD to simplify the instructions for 
correcting a jammed or restricted flight control condition. This 
document corrects the format for certain AFM material described in that 
AD. This correction is necessary to ensure that the flightcrew is aware 
of certain critical recall items in the AFM procedure that are 
necessary to address a condition involving a jammed or restricted 
rudder.

DATES: Effective November 13, 2000.

FOR FURTHER INFORMATION CONTACT: Steve O'Neal, Aerospace Engineer, 
Flight Test Branch, ANM-160S, Seattle Aircraft Certification Office, 
FAA, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone 
(425) 227-2699; fax (425) 227-1181.

SUPPLEMENTARY INFORMATION: On October 20, 2000, the Federal Aviation 
Administration (FAA) issued AD 2000-22-02, amendment 39-11948 (65 FR 
64134, October 26, 2000), which applies to all Boeing Model 737 series 
airplanes. That AD supersedes AD 96-26-07, amendment 39-9871 (62 FR 15, 
January 2, 1997), to require revising the FAA-approved Airplane Flight 
Manual (AFM) procedure in the existing AD to simplify the instructions 
for correcting a jammed or restricted flight control condition. That AD 
was prompted by an FAA determination that the procedure currently 
inserted in the AFM by the existing AD is not defined adequately. The 
actions required by that AD are intended to ensure that the flight crew 
is advised of the procedures necessary to address a condition involving 
a jammed or restricted rudder.

Need for the Correction

    Information obtained recently by the FAA indicates that certain AFM 
material described in AD 2000-22-02 was incorrectly formatted.
    The FAA has determined that a correction to the published format of 
the AFM procedure specified in paragraph (b) of that AD is necessary. 
The procedure contains critical recall (memory) items. The first two 
procedural steps, which call for disengagement of the autopilot and 
autothrottle, and their associated text, are recall items. In standard 
operational materials, recall items are indicated to the flight crew by 
specifying the information in a text box. Any duplication of this 
procedure in operational documentation must reflect the recall nature 
of these items. Therefore, paragraph (b) of this AD has been revised to 
reference Figure 1 of this AD, which contains the correct format in 
order to emphasize these recall items. The correction will ensure that 
the flightcrew is aware of the critical recall items in the AFM 
procedure described in that AD that are necessary to address a 
condition involving a jammed or restricted rudder.

Correction of Publication

    This document corrects the error and correctly adds the AD as an 
amendment to Sec. 39.13 of the Federal Aviation Regulations (14 CFR 
39.13).
    The AD is reprinted in its entirety for the convenience of affected 
operators. The effective date of the AD remains November 13, 2000.
    Since this action only corrects a formatting error, it has no 
adverse economic impact and imposes no additional burden on any person. 
Therefore, the FAA has determined that notice and public procedures are 
unnecessary.

    Air transportation, Aircraft, Aviation safety, Safety.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec. 39.13  [Corrected]

    2. Section 39.13 is amended by correctly adding the following 
airworthiness directive (AD):

2000-22-02 R1  Boeing: Amendment 39-11948. Docket 2000-NM-325-AD.

    Applicability: All Model 737 series airplanes, certificated in 
any category.
    Compliance: Required as indicated, unless accomplished 
previously.
    To ensure that the flight crew is advised of the procedures 
necessary to address a condition involving a jammed or restricted 
rudder, accomplish the following:

Restatement of Certain Requirements of AD 96-26-07

    (a) Within 30 days after January 17, 1997 (the effective date of 
AD 96-26-07, amendment 39-9871): Revise the Emergency Procedures 
Section of the FAA-approved Airplane Flight Manual (AFM) to include 
the following recall item, which will enable the flight crew to take 
appropriate action to maintain control of the airplane during an 
uncommanded yaw or roll condition. This may be accomplished by 
inserting a copy of this AD in the AFM.

``UNCOMMANDED YAW OR ROLL
RECALL

[[Page 69240]]

Maintain control of the airplane with all available flight controls. 
If roll is uncontrollable, immediately reduce angle of attack and 
increase airspeed. Do not attempt to maintain altitude until control 
is recovered. If engaged, disconnect autopilot and autothrottle.''

New Requirements of This AD

    (b) Within 30 days after the effective date of this AD: Revise 
the Normal Procedures Section of the FAA-approved AFM for Model 737-
100 and -200 series airplanes or the Non-Normal Procedures Section 
of the FAA-approved AFM for Model 737-300, -400, -500, -600, -700, 
and -800 series airplanes, as applicable, to include the procedure 
specified in Figure 1 of this AD. This may be accomplished by 
inserting a copy of this AD in the AFM and removing the existing 
copy (inserted as required by AD 96-26-07), entitled ``Jammed Flight 
Controls.''

    (c) It is acceptable to modify the format of the above procedure 
to reflect the format used by individual carriers. However, the 
procedural sequence, memory items, and/or associated text may not be 
modified, except by submitting a request for an alternative method 
of compliance (AMOC) as specified in paragraph (d) of this AD.

Alternative Methods of Compliance

    (d) An AMOC or adjustment of the compliance time that provides 
an acceptable level of safety may be used if approved by the 
Manager, Seattle Aircraft Certification Office (ACO), FAA. Operators 
shall submit their requests through an appropriate FAA Principal 
Operations Inspector, who may add comments and then send it to the 
Manager, Seattle ACO.

    Note 1: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Seattle ACO.

Special Flight Permits

    (e) Special flight permits may be issued in accordance with 
Secs. 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 
21.197 and 21.199) to operate the airplane to a location where the 
requirements of this AD can be accomplished.

Effective Date

    (f) The effective date of this amendment remains November 13, 
2000.

    Issued in Renton, Washington, on November 9, 2000.
