Rear spar finish tape

[HighWing]

That tape has been in the manual since the Dan Denney days. Then, the fabric was the light weight uncertified fabric and maybe there was more movement of the fabric in the prop wash and slightly beyond. I did it on both planes and no regrets.

I wasn't planning on skipping it, just curious.

The wing on bench ,the fabric touch the Spar maybe one inch.. so i think in flight it will be more..

Tape on rear spars was also recommended by a local fabric aircraft refurbishing business friend. He's an A&P and has done beautiful work for years.

I just finished heat tightening, and there is very little clearance between the fabric and the spar. Definitely makes sense now.

The top of the wing is low pressure in flight (it sucks). With just the finish tape over the fabric at the spar (it touches at every bay) I've had no sign of wear in 1,300 hours.
