Life time of the airframe
The maximum life time of the powered sailplane is 12000 hours.
To reach this life time several special inspections of the airframe according the
inspection program are necessary.
When the aircraft has reached a maximum of 6000 hours of service time, a special
inspection of the airframe must be accomplished in accordance with the inspection
program for the extension of the allowed service time.
If the results of this special inspection, possibly after proper repair of detected
defects, are satisfactory, the allowed service time is increased by 3000 hours up to
a maximum of 9000 hours in total.
Thereafter the special inspection in accordance with the above mentioned
inspection program must be repeated in intervals not exceeding 1000 hours. If the
results are satisfactory and the detected defects properly repaired, the allowed
service time may be increased step by step at each inspection by 1000 hours up
to a maximum of 12000 hours in total.
The instructions given in the Ventus-3M Maintenance Manual section 3.3
regarding the inspection procedure for the extension of the allowed service time
must be observed.
