In addition, the original attach blocks are installed prior to the upper stub wing skin, when there was good access to the gear well. With the stub wing skin on, it becomes handicap to work in this very tight area and there's the question of how good a job a builder or other repairman would do in a complete removal and replacement of this critical part. If a complete replacement isn't reasonably well done, a serious problem will have been created. This all argues strongly for the SB leaving existing blocks in place and installing a brace, although I feel certain that Lancair would install a single full-width block if they had it to do over again. I replaced my right-side attach block three years ago because the primary (Hysol) bond failed. I didn't want to go in and replace both sides with my recommended full-width block, so I simply replaced the right side same as originally installed. Now, it shows signs of bond failure again. The left side remains OK. Bill Rumburg N403WR (Sonic bOOm) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html
