Ref. TLI (Total Life Index) 1

[Julio757]

Hi, I´m not familiar with the Total Life Index (TLI) concept. I know that if TLI reaches 2.0, the aircraft is permanently grounded; to adopt 1.75 as TLI limit is based upon acceptance of risk and probably of failure. I wonder if someone could tell me how to calculate the TLI for one aircraft ?

i meant if you were starting to operate the plane you could restrict the cruise altitude to 10,000', and so reduce the pressure stress on the fuselage (at the expense of the rest of the plane). but your plane has been operating for a number of years, the damage (whatever it is) has been done.
