I note that in almost every one of your posts you refer to "aging" or "Geriatric" aircraft. Most of the airline aircraft in Australia have flown many more hours than the average G.A.aircraft. Also, the Caribous, F111's and FA18's are no longer young. But they are all still doing the job, and will for a while yet. It was reported that the B747 at Longreach had flown 91000 hours. Some G.A. aircraft will go to 40000 hours, and some, have no limit specified.There are aircraft in Australia built in the 1940's, still flying. Of course this all depends on good maintenance, and therin lies the problem. We have a serious problem with a shortage of LAME's, and an oversupply of desparate young pilots. The age of the aeroplane is not relevent. The condition of it is.
I wonder if you may be an aeroplane salesman.
