98-14-14: AFM - Limitations Section - Power Levers

98-14-14 MCDONNELL DOUGLAS: Amendment 39-10647. Docket 97-NM-72-AD.\n\n\tApplicability: All turbopropeller-powered McDonnell Douglas Model DC-3 and DC-3C series airplanes, certificated in any category.\n\n\tNOTE 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.\n\n\tCompliance: Required as indicated, unless accomplished previously.\n\n\tTo prevent loss of airplane controllability, or engine overspeed and consequent loss of engine power caused by the power levers being positioned below the flight idle stop while the airplane is in flight, accomplish the following:\n\n\t(a)\tFor turbopropeller-powered McDonnell Douglas Model DC-3 and DC-3C series airplanes on which Rolls-Royce Dart 510 engines are installed: Within 30 days after the effective date of this AD, revise the Limitations Section of the FAA-approved Airplane Flight Manual (AFM) to include the following statements. This action may be accomplished by inserting a copy of this AD into the AFM.\n\n\t"Positioning of power levers below the flight idle stop (i.e., including ground fine pitch) while the airplane is in flight is prohibited. Such positioning may lead to loss of airplane control or may result in an overspeed condition with consequent loss of engine power."\n\n\t(b)\tFor turbopropeller-powered McDonnell Douglas Model DC-3 and DC-3C series airplanes other than those identified in paragraph (a) of this AD: Within 30 days after the effective date of this AD, revise the Limitations Section of the FAA-approved Airplane Flight Manual (AFM) to include the following statements. This action may be accomplished by inserting a copy of this AD into the AFM.\n\n\t"Positioning of power levers below the flight idle stop while the airplane is in flight is prohibited. Such positioning may lead to loss of airplane control or may result in an overspeed condition with consequent loss of engine power."\n\n\t(c)\tAn 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 Operations Inspector, who may add comments and then send it to the Manager, Los Angeles ACO.\n\n\tNOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO.\n\n\t(d)\tSpecial 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.\n\n\t(e)\tThis amendment becomes effective on August 11, 1998.
