Left elevator separated in flight. bolt connecting elevator loosened up and fell out. elevator was damaged and appeared to be bent from aerodynamic forces. aircraft was difficult to control. any control movement caused uncontrollable pitching in the lateral axis. it appeared the 38a bolt loosened up because nut-plate lost it's self locking ability.

From the NTSB's aviation accident database, refreshed monthly; accidents only, homebuilts left out. Counts, not rates: nobody publishes how many hours each model flies, and a training fleet flies far more than a private one. Look up any case by its number in the NTSB's CAROL.

Filled in for a Cessna 150G with the Continental O-200: a typical cruise fuel burn and the engine maker's published overhaul time. Everything else is yours to fill in: insurance, hangar and overhaul prices vary too much by pilot, airport and shop for a default to mean anything. Nothing you type leaves this page.

Before you buy one

Run its N-number through the AD check: every AD that names its airframe and engine, as a checklist to take to the logbooks.
For each repeat-action AD (1 on the airframe), find the last compliance in the logbooks and when the next one is due.
Compare the engine's time since overhaul with its maker's published overhaul time, and look for the reason behind any long gap in flying.
Ask the mechanic doing the pre-buy to look hard at the elevator structure and for loose bolts: they are what gets reported most on this model.
7 equipment ADs name the 150G (a muffler, a seat belt, a display): find out which of that equipment is installed.
Check the registration, the airworthiness certificate and the date of the last annual inspection.
Work out the sales or use tax your state will charge with the aircraft tax calculator.
