What maintenance actions should be performed after replacing an electrical connector on an aircraft harness?

• A. Tighten the screws on the engine.
• B. Inspect contact alignment and seating, verify secure crimped terminals, apply approved anti-oxidant or sealant if required, perform continuity and resistance checks, and re-seal or shield as specified.
• C. Replace only the housing.
• D. Ignore.

Answer: (B)

After replacing an electrical connector on an aircraft harness, you must ensure the connection is clean, secure, and protected from the environment. Start by verifying contact alignment and seating so every pin or blade sits correctly and makes reliable contact. Check that the crimped terminals are securely attached and not damaged or loose. If the maintenance data requires it, apply the approved anti-oxidant or sealant to prevent corrosion and sealout moisture. Then perform continuity and resistance checks to confirm the circuit is complete and within specified limits. Finally, re-seal or shield the connector as specified to maintain environmental protection and EMI performance. Actions like tightening engine screws, replacing only the housing, or ignoring the task do not address the full need for a reliable, protected electrical connection.
