[Docket No. 98-NM-317-AD; Amendment 39-10904; AD 98-24-19]
RIN 2120-AA64
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.
(c) Special flight permits may be issued in accordance with
sections 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.
(d) The AFM revision specified in paragraph (a)(1) of this AD
shall be done in accordance with EMBRAER EMB-145 Airplane Flight
Manual 145/1153, Revision 19, dated October 23, 1998, which contains
