(b) The inspection program specified in paragraph (a)(3) of this section must include at least the following: (1) Instructions, procedures, and standards for the conduct of inspections for the particular make and model of airplane, including necessary tests and checks. The instructions and procedures must set forth in detail the parts and areas of the airframe, aircraft engines, propellers, appliances, and survival and emergency equipment required to be inspected. (2) A schedule for the performance of inspections that must be performed under the program, expressed in terms of the time in service, calendar time, number of system operations, or any combination of these. (c) No person may be used to perform the inspections required by this part unless that person is authorized to perform maintenance under part 43 of this chapter. (d) No person may operate an airplane subject to this part unless— (1) The installed engines have been maintained in accordance with the overhaul periods recommended by the manufacturer or a program approved by the Administrator; and (2) The engine overhaul periods are specified in the inspection programs required by §125.247(a)(3). (e) Inspection programs which may be approved for use under this part include, but are not limited to— (1) A continuous inspection program which is a part of a current continuous airworthiness program approved for use by a certificate holder under part 121 or part 135 of this chapter; (2) Inspection programs currently recommended by the manufacturer of the airplane, aircraft engines, propellers, appliances, or survival and emergency equipment; or (3) An inspection program developed by a certificate holder under this part.

No. 19779, 45 FR 67235, Oct. 9, 1980, as amended by Amdt. 125–2, 46 FR 24409, Apr. 30, 1981] (a) No person may operate an Airbus Model A300 (exlcuding the –600 series), British Aerospace Model BAC 1–11, Boeing Model 707, 720, 727, 737 or 747, McDonnell Douglas Model DC–8, DC–9/MD–80 or DC–10, Fokker Model F28, or Lockheed Model L–1011 beyond the applicable flight cycle implementation time specified below, or May 25, 2001, whichever occurs later, unless operations specifications have been issued to reference repair assessment guidelines applicable to the fuselage pressure boundary (fuselage skin, door skin, and bulkhead webs), and those guidelines are incorporated in its maintenance program. The repair assessment guidelines must be approved by the FAA Aircraft Certification Office (ACO), or office of the Transport Airplane Directorate, having cognizance over the type certificate for the affected airplane. (1) For the Airbus Model A300 (excluding the –600 series), the flight cycle implementation time is: (i) Model B2: 36,000 flights. (ii) Model B4–100 (including Model B4–2C): 30,000 flights above the window line, and 36,000 flights below the window line. (iii) Model B4–200: 25,500 flights above the window line, and 34,000 flights below the window line. (2) For all models of the British Aerospace BAC 1–11, the flight cycle implementation time is 60,000 flights. (3) For all models of the Boeing 707, the flight cycle implementation time is 15,000 flights. (4) For all models of the Boeing 720, the flight cycle implementation time is 23,000 flights. (5) For all models of the Boeing 727, the flight cycle implementation time is 45,000 flights. (6) For all models of the Boeing 737, the flight cycle implementation time is 60,000 flights.
