Hi All,
After reviewing Section OP-62 on the IO-390-EXP119 engine installation it looks like modifications are needed to QB fuselages. Specifically, along the lower forward firewall to modify cowl plates and shims. And along the tunnel area to add 10 nutplates to mount the cooling flap assembly. These areas already come completed in the QB fuselage so approximately 30 rivets will need to be drilled out to complete these changes. The affected KAI Sections are in 28 and 45.
I wanted to hear from anyone that's completed those modifications to a QB fuselage related to OP-62. How big a hassle was it and were there any gotchas along the way to be aware of? I'm trying to decide if the benefits and expense of using the -EXP119 engine are outweighed by the hassle and time to make the required modifications on a QB fuselage. Thanks for everyone's time.
