AD 97-14-16 Airworthiness Directives: Raytheon Aircraft Company (Formerly Beech Aircraft Corporation) Model 1900 Series Airplanes

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

Model 1900, 1900C, and 1900D airplanes (all serial numbers), 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 (d) 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 upon the accumulation of 2,600 ground-air- ground (GAG) cycles or within the next 100 GAG cycles after the effective date of this AD, whichever occurs later, unless already accomplished within the last 2,500 GAG cycles, and thereafter at intervals not to exceed 2,600 GAG cycles. Note 2: The compliance time of this AD takes precedence over the compliance time set out in the Raytheon Safety Communique No. 137, dated May, 1997. Note 3: If the owners/operators of the affected airplane have not kept track of GAG cycles, hours time-in-service (TIS) may be substituted by calculating 2 GAG cycles per hour TIS. For example, 2,600 GAG cycles would equal 1,300 hours TIS. To prevent interference between the flap and the aileron, which could inhibit aileron movement and result in possible loss of control of the airplane, accomplish the following: (a) Inspect the outboard flap attachment brackets and aft roller bearings on both wings for visible wear and elongation of the bracket holes in accordance with instructions 1 through 18 in Raytheon Aircraft (Raytheon) Safety Communique No. 137, dated May 1997. (b) Prior to further flight, repair or replace any worn or damaged part in accordance with Temporary Revision No. 57-1 to the Raytheon Aircraft Beech 1900 Airliner Series Structural Repair Manual P/N 114-590021-9B, dated May 16,1997; Reissued June 30, 1992. (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) An alternative method of compliance or adjustment of the initial or repetitive compliance times that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, Room 100, 1801 Airport Road, 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 Aircraft Certification Office. Note 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita Aircraft Certification Office. (e) The inspections and repairs required by this AD shall be done in accordance with Raytheon Aircraft Safety Communique No. 137, dated May, 1997 and Temporary Revision No. 57-1 to the Raytheon Aircraft Beech 1900 Airliner Series Structural Repair Manual P/N 114-590021-9B, dated May 16,1997; Reissued June 30, 1992. 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. Copies may be obtained from Raytheon Aircraft Company, 9709 E. Central, P. O. Box 85, Wichita, Kansas 67201-0085. Copies may be inspected at the FAA, Central Region, Office of the Assistant Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri, or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. (f) This amendment (39-10074) becomes effective on August 4, 1997. Issued in Kansas City, Missouri, on July 3, 1997.
