ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 75-05-13 GENERAL ELECTRIC: Amendment 39-2114 as amended by Amendment 39-2524. Applies to all General Electric CF700-2C, CF700-2D, and CF700-2D-2 turbofan engines having compound turbine and fan blade, Part Number 6002T57P01, with the following serial numbers: 001CY through 9994CY 001DN through 999DN 001CZ through 1038CZ 001DO through 999DO 001DA through 999DA 001DP through 999DP 001DB through 999DB 001DQ through 999DQ 001DC through 999DC 001DR through 999DR 001DE through 999DE 001DS through 999DS 001DF through 999DF 001DT through 999DT 001DG through 999DG 001DU through 999DU 001DH through 999DH 001DV through 999DV 001DW through 999DW 001DJ through 999DJ 001DX through 999DX 001DK through 999DK 001DY through 999DY 001DL through 999DL 001DI through 999DI 001DZ through 999DZ 001DM through 999DM Compliance required as indicated unless already accomplished. To preclude possible failures of compound turbine and fan blades, perform an eddy current inspection as specified in the Accomplishment Instructions section of General Electric Alert Service Bulletin No. (CF700) A72-124, or (CF700) A72-125 or later FAA approved revisions or a fluorescent-penetrant inspection as specified in General Electric Overhaul Manual SEI-133 Section 72-72-1, or equivalent inspection method approved by the Chief, Engineering and Manufacturing Branch, FAA, New England Region, in accordance with the following schedule: a. Compound turbine and fan blades with 400 or more hours total time in service on the effective date of this AD: Inspect within the next 30 hours time in service and inspect every 400 hours time in service thereafter. b. Compound turbine and fan blades with less than 400 hours total time in service on the effective date of this AD: Inspect prior to the accumulation of 430 hours total time in service and inspect every 400 hours time in service thereafter . Replace all compound turbine and fan blades, confirmed as cracked, prior to further flight. Upon request of the operator, an FAA Maintenance Inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA, New England Region, may adjust the inspection interval specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator. Amendment 39-2114 was effective March 12, 1975. This amendment 39-2524 becomes effective March 3, 1976. FOOTER:
