A standardized inspection methodology for AGL connectors, primarily focused on secondary connectors, L-823 plug/receptacle assemblies, and associated cable leads. Covers contact condition, locking mechanisms, sealing, crimped connections, mating condition, corrosion, overheating, contamination, moisture ingress, identification, and mechanical protection — treating the connector as an electrical interface, not merely a cable accessory.
Critical technical control — A connector may appear externally intact while developing a serious electrical problem because of poor contact engagement, corrosion, contamination, damaged contacts, inadequate crimping, compromised sealing, moisture ingress, excessive mechanical strain, or increased contact resistance. Where there are signs of overheating, repeated intermittent fixture failure, suspected high contact resistance, water ingress, or damaged contacts, the connector should be escalated for the appropriate electrical testing, inspection, repair, or replacement.
Inspection of L-823 connector contacts for cleanliness, corrosion, deformation, contamination, and physical damage.
Inspection of the connector locking arrangement, including engagement, security, and physical damage that could permit unintentional separation.
Inspection of connector bodies, contacts, terminals, and metallic components for corrosion and oxidation, including corrosion associated with moisture penetration.
Inspection of seals, gaskets, boots, and other moisture-protection components for damage, and verification that the connector assembly maintains the required environmental protection.
Inspection for cracks, impact damage, deformation, crushing, or broken components affecting the connector body and structural integrity.
Inspection for evidence of overheating at the connector interface, including discoloration, contact burning, and thermal damage to the body, insulation, seals, and cable leads.
Verification that mating surfaces and accessible connector components remain clean, and that cleaning has been performed using the applicable approved maintenance method where required.
Verification that the plug and receptacle are fully and correctly mated, that the connector reaches the required engagement position, and that the connection remains secure during normal operation.
Inspection of cable leads directly associated with the connector, including insulation, mechanical stress, abrasion, and crimped cable/contact interface condition.
Verification of connector identification against the associated fixture, transformer, cable, circuit, and maintenance records.
Assessment of mechanical protection provided to the connector and cable interface, including strain relief, cable support, and protective sleeves or guards.
Inspection for water, condensation, moisture marks, or evidence of penetration, and identification of contamination or corrosion resulting from moisture exposure.
The component-level checklist spine underlying all 12 topics above — every applicable connector, primarily secondary connectors and associated cable leads, should be assessed, where relevant, against each of the following checks.

Every observation should be assigned an appropriate status:
NormalEquipment/condition satisfactory and operating as expected.
DefectiveAbnormality or defect identified but equipment remains operational or condition does not require immediate withdrawal.
UnserviceableEquipment or system is not available for its intended function.
Immediate Action RequiredCondition presents an operational, electrical, safety, or airside risk requiring immediate escalation/action.
Each connector inspection record should include:
The connector sits within a single electrical interface chain — a fault anywhere in this chain can present as a connector-level defect:
Quick answers about connector inspection in the AGL Inspection Handbook.
Division 10 contains 12 published topics giving a standardized inspection methodology for AGL connectors, primarily secondary connectors, L-823 plug and receptacle assemblies, and associated cable leads. It treats the connector as an electrical interface, not merely a cable accessory.
It checks plug, receptacle, contacts, locking, sealing, crimp, cable lead, corrosion, heating, moisture, identification and mechanical condition. The wider scope also covers mating condition, contamination and mechanical protection.
The checklist includes connector identification and type, plug, receptacle, contacts, contact alignment and security, mating, locking, seal, water protection, moisture, corrosion, cleanliness, housing, overheating signs, cable lead, crimp, strain relief, cable support, bending, pit environment, FOD, continuity or test record and fault history.
Every observation is assigned one of four statuses. Normal means the equipment or condition is satisfactory and operating as expected. Defective means an abnormality or defect exists but the equipment remains operational or the condition does not require immediate withdrawal. Unserviceable means the equipment or system is not available for its intended function. Immediate Action Required means the condition presents an operational, electrical, safety or airside risk requiring immediate escalation and action.
Division 10 treats the connector as an electrical interface, not merely a cable accessory. The checklist therefore records overheating signs as None, Suspected or Confirmed, and crimp condition as Good, Suspect or Damaged.

The airport's approved inspection schedule, SMS procedures, ATC instructions, NOTAM procedures and local aerodrome regulations always take precedence, and the current revision of any official document should be verified before use.

Connector inspection is where primary and secondary cable-joint condition awareness begins. Go beyond identifying defects and build the technical knowledge to understand why abnormalities occur, how they affect system serviceability, and when further testing, troubleshooting, maintenance or corrective action is required.
