There was some mention of an SB-048, which covers the vent at BL-145. This vent runs from the main tank through the main spar into the leading edge of the wing. The purpose is to allow the gas in the leading edge forward of the main spar to drain. The discussion about Tony's crash indicated that this vent was either plugged or non-existant. I contacted Amber Ridell about SB-048, and she kindly and quickly replied as follows: SB048 was for SN#387-416FB only. It was to correct something we did or didn't do on those certain fast builds. So, here is the scoop: You need a hole through the spar at BL-145 to vent the leading edge gas tank, unless your serial number is 387-416FB. In that case, consult the SB. You also need a vent from BL-147 to the exterior NACA scoop to vent all the main tanks in the wing. The hole at each of these locations is easily checked for plugging by inserting a mirror into the fill port and using a small flex-light.
