GROB 109B TBO extension

[prg55100]

Dear all G109B owner,

I fly the G109B D-KBBW S/N 6337 with the Grob 2500E1 engine S/N 4601/EN in service since 8/01/1985.

I passed 2100 hrs and renew yearly Air Worthiness with engine on condition. Compressions and oil analyses are still OK.

I wonder who else flying on condition over TBO on G109B and for how long?

Any experience will be greatly appreciated
