Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model EMB-145 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correcting amendment.

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

SUMMARY: This document corrects information in an existing 
airworthiness directive (AD) that applies to certain Empresa Brasileira 
de Aeronautica S.A. (EMBRAER) Model EMB-145 series airplanes. That AD 
currently requires revising the Performance Section of the Airplane 
Flight Manual (AFM) to provide the flightcrew with procedures to adjust 
landing distances for landings performed with the anti-icing system 
active. That AD also requires revising the Limitations Section of the 
AFM to prohibit certain types of approaches with the anti-icing system 
active. This document corrects a typographical error that resulted in 
reference to a supplement of the AFM that does not exist. This 
correction is necessary to ensure that the appropriate supplement of 
the AFM is revised.

DATES: Effective December 10, 1998.
    The incorporation by reference of certain publications listed in 
the regulations was approved previously by the Director of the Federal 
Register as of December 10, 1998 (63 FR 65050, November 25, 1998).

FOR FURTHER INFORMATION CONTACT: Thomas Peters, Aerospace Engineer, 
ACE-118A, FAA, Small Airplane Directorate, Atlanta Aircraft 
Certification Office, One Crown Center, 1895 Phoenix Boulevard, suite 
450, Atlanta, Georgia 30349; telephone (770) 703-6063; fax (770) 703-
6097.

SUPPLEMENTARY INFORMATION: On November 16, 1998, the Federal Aviation 
Administration (FAA) issued AD 98-24-19, amendment 39-10904 (63 FR 
65050, November 25, 1998), which applies to certain Empresa Brasileira 
de Aeronautica S.A. (EMBRAER) Model EMB-145 series airplanes. That AD 
requires revising the Performance Section of the Airplane Flight Manual 
(AFM) to provide the flightcrew with procedures to adjust landing 
distances for landings performed with the anti-icing system active. 
That AD also requires revising the Limitations Sections of the AFM to 
prohibit certain types of approaches with the anti-icing system active. 
That AD was prompted by a report that increased (i.e., higher than 
normal) flight idle thrust may occur when the anti-icing system is 
active. The actions required by that AD are intended to ensure that the 
flightcrew is advised of appropriate landing field lengths when 
operating with the anti-icing system active, and that instrument 
approaches at certain flap settings are prohibited with the anti-icing 
system active. Increased flight idle thrust when the anti-icing system 
is active, if not corrected, could result in landing overrun.

Need for the Correction

    As published, AD 98-24-19 contains a typographical error in 
paragraph (a)(2) of the AD. That paragraph specified a revision to the 
Limitations Section of Supplement 12 of the FAA-approved AFM; however, 
the correct supplement is Supplement 6. Supplement 12 of the AFM does 
not exist.
    The FAA has determined that a correction to AD 98-24-19 is 
necessary. The correction will ensure that the appropriate supplement 
of the AFM is revised.

Correction of Publication

    This document corrects the error and revises the AD as an amendment 
to section 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 December 10, 1998.
    Since this action only corrects a typographical 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.

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) by making the 
following correcting amendment:

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 revising the following airworthiness 
directive (AD):

98-24-19  Empresa Brasileira de Aeronautica S.A. (EMBRAER): 
Amendment 39-10904. Docket 98-NM-317-AD.

    Applicability: Model EMB-145 series airplanes, equipped with 
Allison Model AE3007A1/2 engines; certificated in any category.
    Compliance: Required as indicated, unless accomplished 
previously.
    To ensure that the flightcrew is advised of appropriate landing 
field lengths when operating with the anti-icing system active, and 
that instrument approaches at certain flap settings are prohibited 
with the anti-icing system active, accomplish the following:
    (a) Within 10 days after the effective date of this AD, 
accomplish the actions specified by paragraphs (a)(1) and (a)(2) of 
this AD.
    (1) Revise the Performance Section of the FAA-approved Airplane 
Flight Manual (AFM) by inserting a copy of EMBRAER EMB-145 AFM 145/
1153, Revision 19, dated October 23, 1998, into the AFM.

    Note 1: When landing in abnormal configurations per the 
emergency and abnormal procedures of Section 3 of the AFM and 
operating with the anti-icing system active, the landing field 
length multiples specified in Section 3 should be applied to the 
landing field lengths specified in Supplement 6 of Revision 19 of 
the AFM.

    (2) Revise the Limitations Section of Supplement 6 of the FAA-
approved AFM to include the following statement. This action may be 
accomplished by inserting a copy of this AD into the AFM.

``Flaps 22 instrument approaches with anti-ice on are not 
approved.''

    (b) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Atlanta Aircraft Certification 
Office (ACO), FAA, Small Airplane Directorate. Operators shall 
submit their requests through an appropriate FAA Principal 
Maintenance Inspector, who may add comments and then send it to the 
Manager, Atlanta ACO.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Atlanta ACO.

CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.
    (d) The AFM revision specified in paragraph (a)(1) of this AD
