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

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 the following list of effective pages:
