Electrical System Inspection Guide
Wires / wiring harness
1. Check for broken, disconnected or corroded bonding strap and grounding
2. Check for Improper, broken, inadequately supported wiring and conduit and loose connections of
terminals. Check conditions of clamps, plastic cable ties and rubber grommets. Clamp retaining
screws should be properly secured. Cables in the positions of cable ties should show no sign of
damage. Rubber grommets should be securely installed in holes.
3. Ensure wires passing through firewall fairleads are properly sealed with PPG P/S 890 Class B (refer to
section
24-03 ).
4. Check interference between wires and control mechanism, specifically, front rudder pedal adjusters
and bellcranks, center rudder bellcranks, and control sticks.
5. If any electrical devices or signals are removed permanently or temperately, ensure that wires left
open accordingly are individually dead-ended, tied into a bundle and secured to a permanent
structure.
6. Wiring must be replaced with equivalent wire when found to have any of the following defects:
- Wiring that has been subjected to chafing or fraying, that has been severely damaged, or that
primary insulation is suspected of being penetrated.
- Wiring on which the outer insulation is brittle to the point that slight flexing causes it to crack.
- Wiring having weather-cracked outer insulation.
- Wiring that is known to have been exposed to electrolyte or on which the insulation appears to
be, or is suspected of being, in an initial stage of deterioration due to the effects of electrolyte.
- Check wiring that shows evidence of overheating for the cause of the overheating.
- Wiring on which the insulation has become saturated with engine oil, hydraulic fluid or other
lubricant.
- Shielded wiring on which the metallic shield is frayed and/or corroded. Cleaning agents or
preservatives should not be used to minimize the effects of corrosion or deterioration of wire
shields.
- Wiring showing evidence of breaks, cracks, dirt, or moisture in the plastic sleeves placed over
wire splices or terminal lugs.
7. When required, wires must be replaced in accordance with wiring diagrams in section 24-03 .
Choose unshielded wires from table below:
