Aircraft On Ground or AOG is a term in aviation maintenance indicating that a problem is serious enough to prevent an aircraft from flying.[1] This can involve problems as simple as a light bulb being out, or as complex as a damaged engine. Boeing estimates that a 1-2 hour AOG situation will cost an airline from $10,000 to $20,000 and possibly even as high as $150,000 per hour depending on the type of aircraft and route flown.[2]
Causes of AOG incidents
editAOG incidents can arise from various factors, including:[citation needed]
- Mechanical failures: Unexpected mechanical issues or failures during flight or pre-flight checks can ground an aircraft.
- Maintenance delays: Scheduled maintenance that extends beyond the expected timeframe can result in AOG status.
- Supply chain issues: Delays in obtaining necessary parts or components can hinder timely repairs, leading to extended grounding periods[3]
- Regulatory compliance: Aircraft may be grounded due to non-compliance with safety regulations or certification requirements.
