Question
Dear Jan

What is the life of a commercial aircraft?.

Thanks
Prashant

Answer
The question is unclear - I am going to assume you mean "What is the lifetime of a commercial aircraft?"

Aircraft are typically flown "On condition" which means that they are flown as long as the parts and condition can be kept air worthy. For small single engine aircraft, they are pretty much wore out after 10,000 - 15,000 hours. Commercial jets are usually not economical to fly more than 30,000 - 50,000 hrs.

Of course there are many factors that may increase the life of an airplane. If it is flown in mild climates - low humidity and mild temperatures, low sand or dust, and sheltered (i.e. hanger) from strong sunlight; the lifetime can be doubled or tripled.
