Extra 300 Safety — Aerobatic Spar Life, G-History & Training | AeroGurus
Editorial safety summary — see Extra 300 listings and consult a qualified A&P/inspector for individual aircraft decisions.
The Extra 300/330 is a purpose-built unlimited-aerobatic aircraft, and its safety hinges on **structural life management and pilot proficiency**, not random failures. The single most important item is the **wing-spar life-limit and inspection status** — competition aerobatic aircraft accumulate high-g cycles, and Extra's carbon spars carry inspection/life requirements that must be documented. Beyond the spar: g-history, the integrity of the inverted fuel/oil systems, and — above all — the pilot's aerobatic qualification. These are demanding, high-performance machines; most incidents are pilot/aerobatic-judgement related (over-g, low-level aerobatics, disorientation).
Common safety topics
- Wing-spar life & inspection — verify spar hours/life-limit and all aerobatic inspections (non-negotiable).
- G-history — competition vs sport use; how hard and how much it's been flown.
- Inverted systems — fuel/oil inverted system operation and condition.
- Engine/prop — Lycoming AEIO-540 + constant-speed prop; time/overhaul; prop AD/inspection status.
- Aerobatic proficiency — unlimited-capable airframe demands serious, current aerobatic training.
Pre-buy safety checklist

- Complete g/aerobatic history from logs.
- Inverted fuel/oil system check; carbon-airframe condition (no hidden over-g/repairs).
- Engine/prop times + overhaul; governor condition.
- Your aerobatic currency/training plan.
