25 year average lifespan continues to be an accurate measurement.
This increases to 27.4 years if "involuntary" retirements (i.e. accidents and incidents where the aircraft is written off) are excluded.
35% of all retirees had been previously stored for more than 5 years. From an investor’s standpoint, this down-time is of little or no value and the analysis should therefore start the retirement clock at the point of initial storage. This further, but critical, adjustment reduces the average age at retirement by 1.5 years to 25.9 years.Over 31,000 jet airliners have been delivered since the dawn of the jet age and two thirds of them are in service today. The vast majority (96%) have been operated for commercial purposes by airlines over most, if not all, of their lives which, on average, have spanned 25.6 years.
Most retirement decisions are a direct and simple function of age, when an operator concludes that the cost of maintaining and operating an aircraft exceeds the financial contribution it can earn.
Often the decision is triggered by a specific event, usually the requirement to complete a costly major maintenance event.
At certain times in an industry cycle, the value of an aircraft, even a relatively young one, may be exceeded by the value of its major components, especially engines, causing owners (though not usually operators) to retire the asset prematurely for part-out.
The regionals tend to do more short haul like this plane did. Hops. I found this fascinating and important to add in to this crash.
The regional jet category, ., appears to display very different characteristics, with an average retirement age of 12 years.
..........the A320 family database, average age at retirement increases from 18.3 years to 19.1 years. For A320s only, the average age is 19.4 years.

This issue is vital - in that it will IMO impact recoery decisions. If the search is going into with the notion of a bomb the tail and fuselage of the aircraft become more important.
If they are going into the search with the notion of mechanicl/fire, the cockpit/avionics (Wiring) would be most important to pull up.
It changes the priorites of the recovery operation IMO
