Typical glider service lives?

Is this typical of other modern ships like the Discus, Ventus, LS, DG series etc?? Most new glider designs come to market with an initial service life, which currenty seem to be 3000 or 6000Hrs. When some examples reach that initial limit the manufacturer (assuming they still exist) then define an inspection program to be undertaken which allows the life to be extended be say 6000Hrs. The process repeats when one gets to 6000Hrs etc. If you look in the TN/ADs from the various maufactureres you will find technical notes being issued defining extensions. Example the LS4 originally had a service life of 3000Hrs. TN4027a for the LS4 now details the inspection program as at 3000, 6000, 9000, 10000 and 11000 which allows a service life up to 12000Hrs. DG and Schleicher still seem to start with 3000Hrs as did earlier Schempp Hirth gliders. Later Schempp gliders have 6000Hrs as the initial life. The SZD-55 is probably an example that the life was initially 3000Hrs after which SZD produced an extension up to 4500Hrs. The original SZD manufacturer didn't really exist for a while so nothing further happened. The newer Allstar PZL company which now owns the design and manufactures the glider produced a TN to extend the life upto 12000 hrs in 2012 Nick -- Nick Hill |
