Exchange Releases

The exchange release principle is a special service we offer our customers: Exchange releases are used, fully overhauled units, which we supply with an EASA FORM 1. If a release needs to be overhauled during the flying season but time is short, using an TOST exchange release can save valuable time.

When ordering an exchange release, we need the following information from you:

•  Your name, billing and shipping address
•  The type of release to be replaced
•  The serial number of your release
•  The lever and lever type
•  The aircraft type
•  A photo, if possible

You can place your order by email or phone, or use our order form.

Here you can find the detailed guide for ordering a TOST exchange release.

New TBO of Tost releases

valid from July 2001

TBO 2000 Starts
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 – like in Germany – this is, as before, 2000 launches.

Should you have more actuations per launch in pure training operation the TBO is reduced accordingly (e. g. with 8 actuations per launch the TBO would be 1250 launches).

If you have only 2 actuations per launch, the TBO consequentially would be 5000 launches. This decision – after how many launches the 10.000 actuations are accomplished – is 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 having performed the adequate number of 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 July 12, 2001 and therefore is valid right now. Please note that the new regulation can be applied only to releases which had a valid certificate in 2001!
