Lighting Inspections Are Not Optional, They Are Federal Law
In this recap of Episode 3 of our YouTube educational series, we’ll help you understand all the monitoring and inspection requirements to ensure full FAA compliance of your obstruction lighting systems.
Tower lighting inspections are required for federal compliance and public safety. Failing to inspect and document your lighting systems can result in:
- Regulatory violations
- NOTAMs
- Fines and enforcement actions
- Aviation safety risks
At LumenServe, we help tower owners stay fully compliant by simplifying every inspection requirement.
Quarterly Lighting Inspections (FCC Requirement)
Under 47 CFR §17.47, the FCC requires:
“You shall inspect at intervals not to exceed three months all automatic or mechanical control devices, indicators, and alarm systems associated with the antenna structure lighting to ensure that such apparatus is functioning properly.”
These quarterly inspections must include:
- Testing each beacon
- Verifying power supply and controller logs
- Confirming photocell day/night switching
- Checking alarms and monitoring systems
These inspections catch failures early—before they become violations or safety risks.
Biennial Lens Inspections (FAA Requirement)
Under FAA Advisory Circular 70/7460-1, lens inspections are required every 24 months (or when a fixture fails).
Lenses must be visually inspected for:
- UV damage
- Cracks or crazing
- Dirt and debris buildup
- Light output deterioration
Damaged or dirty lenses must be cleaned or replaced to maintain certified light intensity.
Paint Inspections for FAA Style A Towers
For towers marked with aviation orange and white paint:
“Antenna structures requiring painting shall be cleaned or repainted as often as necessary to maintain good visibility.”
Paint inspections must use the FAA In-Service Aviation Orange Tolerance Chart and be sampled:
- On the upper half of the structure
- On two separate sides
Faded, peeling, or discolored paint can trigger violations or require a NOTAM.
Documentation Is Your Compliance Shield
Every inspection should be:
- Photographed and video documented
- Logged in federal-compliant records
- Retained for audits and enforcement protection
This creates audit-ready proof of compliance and protects your organization.
Stay Safe. Stay Compliant.
Understanding and executing inspection requirements is essential for tower owners, operators, and compliance teams.
