Section 3 relates to the specific duty and is divided in four sepa-rate parts:
1. Mechanical part, related to the engine overhaul,limited to those components with different characteristicsbased on the relating specific duty.2. Electrical part, concerning wiring harness, electricaland electronic equipment with different characteristicsbased 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 simpleand direct instructions to identify the cause of themajor incon-veniences.
Sections 4 and 5 illustrate the overhaul operations of the engi-ne overhaul on stand and the necessary equipment to executesuch operations.
