Section 1 describes the F4A engine illustrating its features
and working in general.
Section 2 describes the type of fuel feed.
Section 3 relates to the specific duty andis dividedin four sepa-
rate parts:
1. Mechanical part, related to the engine overhaul,
limited to those components with different characteristics
based on the relating specific duty.
2. Electrical part, concerning wiring harness, electrical
and electronic equipment with different characteristics
based on the relating specific duty.
3. Maintenance planning and specific overhaul.
4. Troubleshooting part dedicated to the operators who,
being entitled to provide technical assistance, shall have simple
and direct instructions to identify the cause of the major incon-
veniences.
Sections 4 and 5 illustrate the overhaul operations of the engi-
ne overhaul on stand and the necessary equipment to execute
such operations.
Installation general prescriptions are reported within the ap-
