AD 99-16-12 Airworthiness Directives; Raytheon Aircraft Company Model Beech 1900D Airplanes

Makes named: beech, raytheon. Models named: Beech 1900D. Read the applicability below — it usually turns on serial or part numbers too.

Model Beech 1900D airplanes, serial numbers UE-1 through UE-246, certificated in any category, that incorporate the electric elevator trim option. 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 within the next 600 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished. To prevent failure of the electric elevator trim and difficulty operating the manual elevator trim caused by moisture freezing on parts of the electric actuator installation, which would result in the pilot having to apply constant pressure to the control wheel during flight, accomplish the following: (a) Install electric elevator trim servo covers in accordance with the instructions in Kit No. 129-5035-1, as referenced in Raytheon Mandatory Service Bulletin SB 27-3080, Issued: October, 1998, and Raytheon Mandatory Service Bulletin SB 27-3080, Revision 1, Issued: December, 1998. Note 2: The compliance time of this AD takes precedence over the compliance time specified in Raytheon Mandatory Service Bulletin SB 27-3080, Revision 1, Issued: December, 1998. (b) Special flight permits may be issued in accordance with Secs. 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. (c) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office (ACO), 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita ACO. (d) The installation required by this AD shall be done in accordance with the instructions in Kit No. 129-5035-1, as referenced in Raytheon Mandatory Service Bulletin SB 27-3080, Issued: October, 1998, and Raytheon Mandatory Service Bulletin SB 27-3080, Revision 1, Issued: December, 1998. 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.
