Models named: Avro 146-RJ70A, -RJ85A, -RJ100A. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model Avro 146-RJ70A, -RJ85A, and -RJ100A airplanes; equipped with Honeywell Standard Windshear Detection and Recovery Guidance System (WSS), part number 4048300-902; certificated in any category.
Compliance
Required as indicated, unless accomplished previously. To ensure that the flight crew is aware of significant delays in the Windshear Detection and Recovery Guidance System (WSS) detecting windshear when the flaps of the airplane are in transition, accomplish the following: (a) Within 14 days after the effective date of this AD, revise the Limitations Section of the FAA-approved Airplane Flight Manual (AFM) to include the following statement. This may be accomplished by inserting a copy of this AD in the AFM. ``During sustained banks of greater than 15 degrees or during flap configuration changes, the Honeywell Windshear Detection and Recovery Guidance System (WSS) is desensitized and alerts resulting from [[Page 20889]] encountering windshear conditions will be delayed. (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, Los Angeles Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Operations Inspector, who may add comments and then send it to the Manager, Los Angeles ACO. Note: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles 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) This amendment becomes effective on May 15, 1995. Issued in Renton, Washington, on April 21, 1995. Darrell M. Pederson, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service. [FR Doc. 95-10319 Filed 4-27-95; 8:45 am] BILLING CODE 4910-13-U
