FAQ
What's Covered in a 91.411 Inspection?
The pitot-static system provides critical airspeed and altitude data. During this inspection, we:
- Check for leaks or blockages in the pitot and static lines
- Test altimeter accuracy
- Confirm proper encoding altitude reporting to ATC
- Inspect the static source and alternate static system, if applicable
We use calibrated test equipment to simulate altitude and pressure changes, verifying your system’s integrity under controlled conditions.
What's Covered in a 91.413 Inspection?
The transponder is vital for radar identification and ADS-B communication. In this portion of the inspection, we:
- Test transponder transmission and reply accuracy
- Verify Mode A/C/S function
- Confirm that your transponder is transmitting correct squawk codes and altitude
- If equipped, test ADS-B Out performance (per FAA standards)
How Long Does It Take?
- Most tests can be completed same day or within 24 hours, depending on aircraft type and accessibility of the systems.
What Happens If You Skip It?
Flying with expired inspections can result in:
FAA enforcement action
ATC denying entry into controlled airspace
Voided insurance claims in the event of an incident
