We are issuing this AD to prevent loss of engine power due to cracks in the cylinder head and possible engine failure caused by separation of a cylinder head. \n\nCompliance \n\n\t(e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done. \n\nIdentifying Suspect Cylinders \n\n\t(f) Within 50 hours time-in-service (TIS) after the effective date of this AD, identify, and if necessary replace cylinders, ECi P/N AEC631397 as follows: \n\n\t(1) Identify the cylinder serial number (SN) as follows: \n\n\t(i) Determine the SN of the cylinder by looking in the engine records or by inspecting the cylinder for a SN on the intake port boss (see Figure 1) or on the flat area next to the head to barrel junction (see Figure 2). Disregard any dash numbers that might follow the four digit SN. \n\n\n\n\nFigure 1.\n\n\n\n\nFigure 2.\n\n\n\n\t(ii) If the SN is 1043 or lower, or if it is 7709 or higher, no further action is required. \n\n\t(2) If the cylinder SN is 1044 through 7708, do the following: \n\n\t(i) Remove the rocker box cover from the cylinder. \n\n\t(ii) Look at the left-front cylinder casting. \n\n\t(iii) If the casting has AEC65385, and an "O" under the ECi logo, the cylinder is P/N AEC631397. See Figure 3. \n\n\n\n\nFigure 3.\n\n\n\t(iv) If the cylinder is not ECi P/N AEC631397, no further action is required.(3) If the cylinder is ECi P/N AEC631397, do the following: \n\n\t(i) Look at the flange of the rocker box. \n\n\t(ii) If there is a letter "A," "B," or "X" stamped on the flange of the rocker box, no further action is required. See Figure 4.\n\n\n\nFigure 4.\n\n\n\t(iii) If there is no letter "A," "B," or "X" stamped on the flange of the rocker box, replace the cylinder before further flight. \n\nAlternative Methods of Compliance \n\n\t(g) The Manager, Special Certification Office, has the authority to approve alternative methods of compliance for this AD if requested using the procedures found in 14 CFR 39.19. \n\nMaterial Incorporated by Reference \n\n\t(h) None. \n\nRelated Information \n\n\t(i) ECi Mandatory Service Bulletin S.I. No. 04-1, revision 1, dated March 11, 2004, also pertains to this subject of this AD.
