Brief Description:  Forward Fuselage Prep

Today I finished transfer drilling the left forward skin holes to the welded frame, then updrilled the holes to #30.

While mounting the forward fuselage side skins, I found that the flap drive holes in the skins did not align with the flap bearing mounts in the fuselage frame. An e-mail to SPA asking about the issue received a quick e-mail response from Rachel advising me to elongate the hole to fit. Turns out there was a Part Revision Log issued over three months ago advising of this issue on the original skins and how to deal with it. The lesson learned . . . Keep up with the revision logs. The information is there but doesn’t help much if you forget to read it.

Image #1 shows the misalignment of the skin hole with a steel tube positioned through the flap drive bearing mounts, and image #2 shows the easily applied modification. This area is hidden by the wing, so it is not a significant issue.
