PART 43_MAINTENANCE, PREVENTIVE MAINTENANCE, REBUILDING, AND ALTERATION

--Table of Contents

 

Sec. 43.15  Additional performance rules for inspections.



    (a) General. Each person performing an inspection required by Part 

91, 123, 125, or 135 of this chapter, shall--

    (1) Perform the inspection so as to determine whether the aircraft, 

or portion(s) thereof under inspection, meets all applicable 

airworthiness requirements; and

    (2) If the inspection is one provided for in Part 123, 125, 135, or 

Sec. 91.409(e) of this chapter, perform the inspection in accordance 

with the instructions and procedures set forth in the inspection program 

for the aircraft being inspected.

    (b) Rotorcraft. Each person performing an inspection required by 

Part 91 on a rotorcraft shall inspect the following systems in 

accordance with the maintenance manual or Instructions for Continued 

Airworthiness of the manufacturer concerned:

    (1) The drive shafts or similar systems.

    (2) The main rotor transmission gear box for obvious defects.

    (3) The main rotor and center section (or the equivalent area).

    (4) The auxiliary rotor on helicopters.

    (c) Annual and 100-hour inspections. (1) Each person performing an 

annual or 100-hour inspection shall use a checklist while performing the 

inspection. The checklist may be of the person's own design, one 

provided by the manufacturer of the equipment being inspected or one 

obtained from another source. This checklist must include the scope and 

detail of the items contained in appendix D to this part and paragraph 

(b) of this section.

    (2) Each person approving a reciprocating-engine-powered aircraft 

for return to service after an annual or 100-hour inspection shall, 

before that approval, run the aircraft engine or engines to determine 

satisfactory performance in accordance with the manufacturer's 

recommendations of--

    (i) Power output (static and idle r.p.m.);

    (ii) Magnetos;

    (iii) Fuel and oil pressure; and

    (iv) Cylinder and oil temperature.

    (3) Each person approving a turbine-engine-powered aircraft for 

return to service after an annual, 100-hour, or progressive inspection 

shall, before that approval, run the aircraft engine or engines to 

determine satisfactory performance in accordance with the manufacturer's 

recommendations.

    (d) Progressive inspection. (1) Each person performing a progressive 

inspection shall, at the start of a progressive inspection system, 

inspect the aircraft completely. After this initial inspection, routine 

and detailed inspections must be conducted as prescribed in the 

progressive inspection schedule. Routine inspections consist of visual 

examination or check of the appliances, the aircraft, and its components 

and systems, insofar as practicable without disassembly. Detailed 

inspections consist of a thorough examination of the appliances, the 

aircraft, and its components and systems, with such disassembly as is 

necessary. For the purposes of this subparagraph, the overhaul of a 

component or system is considered to be a detailed inspection.

    (2) If the aircraft is away from the station where inspections are 

normally conducted, an appropriately rated mechanic, a certificated 

repair station, or the manufacturer of the aircraft may perform 

inspections in accordance with the procedures and using the forms of the 

person who would otherwise perform the inspection.
