Models named: Avro 146-RJ100A series. Read the applicability below — it usually turns on serial or part numbers too.

Model BAe Avro 146-RJ85A series airplanes, serial numbers E2296, E2297, E2299, E2300, E2302, E2303, E2304, E2305, E2306, and E2307; and Model Avro 146-RJ100A series airplanes, serial numbers E3298, E3301, and E3308; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously. To prevent failure of the electrical circuit terminal lugs, which could result in electrical system failure, and consequent reduced controllability of the airplane, accomplish the following: (a) Within 6 months after the effective date of this AD, perform a one-time visual inspection of the electrical wires, having part numbers (P/N) MD0011N and MD0012N, in the electrical equipment bay and hydraulic equipment bay, to determine if any ERMA terminal lug having P/N ERMA 12115/2 is installed, in accordance with British Aerospace Service Bulletin SB.24-120, dated September 18, 1997. If any ERMA terminal lug is found, prior to further flight, remove the lug and replace with an AMP terminal lug having P/N AMP 323064, in accordance with the service bulletin. (b) As of the effective date of this AD, no person shall install an ERMA terminal lug, P/N ERMA 12115/2, on any airplane. (c) 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, International Branch, ANM-116, FAA, Transport 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, International Branch, ANM-116. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. (d) 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. (e) The inspection and replacement shall be done in accordance with British Aerospace Service Bulletin SB.24-120, dated September 18, 1997. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
