Check intervall
We schedule a trim inspection (NOVA Trim Tuning NTT) within the first year
after the date of purchase (new glider) In the case that the NTT is not done, the
wing needs a full check after 2 years after purchase (new glider). The check
expert can define the next check interval on the basis of the wing’s condition.
In areas where conditions are harsh on the material (i.e. by salty air and sand
next to the coast), an annual complete check (NFS) is strongly recommended!
We recommend the same for wings which are used for regular acro flying.
The date of purchase of the new glider is decisive for any deadline concerning
NTT and NFS, as well as for guarantee.
Attention:
In the case of commercially used gliders, (tandems or school gliders) the NFS
has to be performed every year.
Independent from the deadlines mentioned above:
A check (NFS) has to be performed not later than every 200 hours of flight, or
every 400 flights. (Depending on what happens first.)
The check has to be confirmed with the check-stamp on the stabilo. All
necessary documents for the inspection can be found on the NOVA homepage
(http://www.nova-wings.com): Service & Downloads
Performing the Check
Identifying the glider
The glider type and the serial number of the glider can be found on the wing
tip. Please ensure that the certification tag is on the middle rib of the wing.
Checking the porosity
The porosity check has to be performed on 5 spots on the top sail. These spots
have to be clean (no sand, no dust) and without damage (e.g. small holes).
Otherwise the result would be falsified.
The average value on the top sail has to be used to judge the gliders condition.
If one value is a lot lower than the other values, please repeat the measurement
and move the measurement spot slightly.
