AD 2000-07-51 Airworthiness Directives; McDonnell Douglas Model 717-200 Series Airplanes

Models named: 717-200 series. Read the applicability below — it usually turns on serial or part numbers too.

All Model 717-200 series airplanes, 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 loss of all altitude information and subsequent essential navigation data for continued safe flight and landing, accomplish the following: (a) Prior to further flight, coil and stow the electrical wires between the glareshield control panel and the Integrated Standby Instrument System in accordance with Boeing Alert Service Bulletin 717-34A0002, dated March 30, 2000. (b) Prior to further flight, revise the abnormal procedures of the Procedures section of the FAA-approved Airplane Flight Manual (AFM) to include procedures for identifying and pulling certain circuit breakers. This must be accomplished by inserting Boeing Interim Operating Procedure 2-17, dated March 31, 2000, into the AFM. Alternative Methods of Compliance (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, Los Angeles Aircraft Certification Office (ACO), 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, Los Angeles ACO. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO. Special Flight Permits (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. Incorporation by Reference (e) The actions shall be done in accordance with Boeing Alert Service Bulletin 717-34A0002, dated March 30, 2000; and Boeing Interim Operating Procedure 2-17, dated March 31, 2000.
