In 2005 was 3000h inspection made and service time of glider was extended by 1000h to 4000h. Meanwhile in 2007 was TN27 released. Now I got 4000h. Do I have to make another "3000h" inspection or just wait for 6000h?
(The glider may only be operated, when within the last 3000 operational hours the glider was either built or its service time was sucessfully extended)
