AD 98-06-19 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Models named: EMB-145 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model EMB-145 series airplanes, serial numbers 145004 through 145018 inclusive; equipped with a speed brake actuator assembly having part number 360540-1001, or a spoiler actuator assembly having part number 360440-1001; 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 (e) 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.
Compliance
Required as indicated, unless accomplished previously. To prevent asymmetric deployment of the speed brakes during flight and consequent reduced controllability of the airplane; or failure of the ground spoilers to deploy during landing or rejected takeoff, which could result in increased aircraft stopping distances; accomplish the following: (a) Within 400 flight hours after the effective date of this AD, drain and seal the ground spoiler and speed brake actuators in accordance with EMBRAER Service Bulletin 145-27-0029, dated November 10, 1997. (b) Within 90 days after the effective date of this AD, replace the spoiler actuator assembly and the speed brake actuator assembly with modified actuator assemblies in accordance with EMBRAER Service Bulletins 145-27-0013, and 145-27-0014, both dated August 20, 1997. (c) Airplanes on which the replacements required by paragraph (b) of this AD are performed within the compliance time specified in paragraph (a) of this AD are not required to accomplish the action required by paragraph (a). (d) As of the effective date of this AD, no person shall install a ground spoiler actuator assembly having part number 360440-1001, or speed brake actuator assembly having part number 360540-1001, on any airplane. (e) 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 [[Page 12611]] 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. (f) 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. (g) The actions shall be done in accordance with EMBRAER Service Bulletin 145-27-0029, dated November 10, 1997; EMBRAER Service Bulletin 145-27-0013, dated August 20, 1997; and EMBRAER Service Bulletin 145-27-0014, dated August 20, 1997.
