New TBO of Tost releases  April 19, 2001

    TBO 2000 launches
          accordingly 10.000 actuations.

Life limiting part is the release spring, with a life expectancy of about
10.000 actuations. With about 5 actuations in normal flight operation, 
this is, as before, 2000 launches.
Should you have in pure training operation more actuations per launch, 
the TBO is reduced accordingly (with 8 actuations per launch to 1250 launches).
This decision in in the responsibility of the aircraft holder.

If both releases are actuated together (like in Germany) both releases
have to be sent for overhaul after 2000 launches.

The life limit of 4 years is replaced by a manufacturer's recommendation.

The new regulation had been published from the LBA in the "NfL" on 
Juli 12, 2001 and therefore is valid right now. The new TBO regulation is
applicable for all releases, which have got a valid certificate of airworthiness
at the date of publishing of the Technical Note.
