AD 2009-13-02 Airworthiness Directives; Fokker Model F.28 Mark 0100 Airplanes

Models named: F.28 Mark 0100. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Fokker Model F.28 Mark 0100 airplanes, certificated in any category, equipped with Rolls-Royce (RR) TAY 650-15 engines.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Certain Requirement of AD 98-06-07 Airplane Flight Manual (AFM) Revision (g) Within 72 hours after March 27, 1998 (the effective date of AD 98-06-07), revise the Limitations Section of the FAA-approved AFM to add the following. This may be accomplished by inserting a copy of this AD in the AFM. “LIMITATIONS POWERPLANT and APU LIMITATIONS OPERATING LIMITS • To avoid high fan blade stresses, stabilized operation in the speed range between 60% and 75% Low Pressure Rotational Speed (N1) is not permitted during Ground Operations in Forward or Reverse Thrust, except that passing through this range while increasing or decreasing thrust is permitted. 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. —Momentarily exceeding the idle detent position, while selecting idle reverse, is acceptable. Emergency Operation: —In case of emergency, the emergency maximum reverse thrust may be used. —If directional control problems occur, reduce to idle reverse or select forward idle. —Stabilized operation with the reverse lever in an intermediate position between idle reverse and emergency maximum reverse is prohibited, except (where approved) during Power-Back operations.” Note 1: Fokker Services Manual Change Notification—Operational Documentation (MCNO) No. F100-006, dated November 27, 1997, contains information that pertains to this subject. Rolls-Royce PLC Engine Operating Instruction Manual Reference F-TAY-3RR, revised by transmittal letter No. 13, dated October 15, 1997, also pertains to this subject. New Actions Required by This AD Removal of Normal Maximum Detent (h) Within 12 months after the effective date of this AD, remove the normal maximum (second) detent for the reverse-thrust control, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-76-014, Revision 2, dated December 12, 2007. Accomplishing the removal terminates the requirements of paragraph (g) of this AD. (i) Actions done before the effective date of this AD in accordance with Fokker Service Bulletin SBF100-76-014, dated October 1, 2001; or Revision 1, dated June 1, 2002; are acceptable for compliance with the requirements of paragraph (h) of this AD. AFM Revision (j) Concurrently with the requirements of paragraph (h) of this AD, revise the Limitations Section of the Fokker F.28 Mark 0100 AFM to include the following (this may be accomplished by inserting a copy of this AD into the AFM): “THRUST REVERSERS Thrust reversers are intended for ground use only. Intentional use of reverse thrust in flight is prohibited. The use of Max Reverse thrust is limited to operations on short runways or on runways with a reduced runway surface friction coefficient or in emergency conditions. Max Reverse thrust shall not be used at airspeeds below 60 knots except in emergency conditions. Reverse thrust selections between Idle Reverse thrust and Max Reverse thrust are prohibited.” Note 2: Fokker Manual Change Notification—Operational Documentation (MCNO) F100-032, Revision 1, dated September 21, 2007, contains information related to the AFM revision required by paragraph (j) of this AD. Alternative Methods of Compliance (AMOCs) (k) The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Tom Rodriguez, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-1137; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. Related Information (l) European Aviation Safety Agency Airworthiness Directive 2008-0089, dated May 13, 2008, also addresses the subject of this AD. Material Incorporated by Reference (m) You must use Fokker Service Bulletin SBF100-76-014, Revision 2, dated December 12, 2007, as applicable, to do the actions required by this AD, unless the AD specifies otherwise.

This AD results from issuance of mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to prevent inadvertent operation in the prohibited stabilized engine speed range on the ground, which could result in uncontained engine fan blade failure due to high cycle fatigue cracking.
