AD 97-19-16 Airworthiness Directives; Fokker Model F28 Mark 0100 Series Airplanes
Models named: F28 Mark 0100 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model F28 Mark 0100 series airplanes equipped with Rolls-Royce (RR) Tay 650-15 engines, 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.
Compliance
Required as indicated, unless accomplished previously. To prevent uncontained failure of the engine fan blades, which could result in loss of thrust from the affected engine, and secondary damage to the airplane and/or fire, accomplish the following: (a) Within 72 hours after the effective date of this AD, revise the Limitations Section, Subsection 2.06.01 ``Thrust Reverser,'' of the FAA-approved Airplane Flight Manual (AFM) to add the following. This may be accomplished by inserting a copy of this AD in the AFM. ``THRUST REVERSER Thrust reversers are intended for ground use only. Intentional use of reverse thrust in flight is prohibited. After reverse thrust has been initiated, a full stop landing must be made. Maximum Reverse Thrust Lever Positions Normal Operation: --The idle detent position shall not be exceeded in normal operation. Emergency Operation: --In case of emergency, the emergency maximum reverse thrust may be used. --Stabilized operation with the reverse lever in an intermediate position between idle reverse and emergency maximum reverse is prohibited. --If directional control problems occur, select forward idle. Exceeding the idle reverse thrust limitations must be reported.'' (b) If the idle reverse thrust limitations specified in paragraph (a) of this AD are exceeded, within 10 days after exceeding the idle reverse thrust limitations, submit a report of that occurrence to Fokker Services, Technical Support Department, P. O. Box 75047, 1117 ZN Schiphol Airport, The Netherlands. Information collection requirements contained in this regulation have been approved by the Office of Management and Budget (OMB) under the [[Page 54581]] provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.) and have been assigned OMB Control Number 2120-0056. (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, Standardization Branch, ANM-113, 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, Standardization Branch, ANM-113. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (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. Note 3: The subject of this AD is addressed in Netherlands airworthiness directive BLA 1997-091(A), dated September 9, 1997. (e) This amendment becomes effective on October 27, 1997, to all persons except those persons to whom it was made immediately effective by emergency AD 97-19-16, issued on September 12, 1997, which contained the requirements of this amendment. Issued in Renton, Washington, on October 15, 1997. James V. Devany, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service.
