Sabremech Posted June 27, 2015 Report Posted June 27, 2015 Today I started on SB 217 installing a doubler on the aft spar to remedy cracks. In the instructions it says to remove the baggage floor. Has anyone here removed the baggage floor? Looks to be a bit of a pain. Here's a picture of the crack. David Quote
takair Posted June 27, 2015 Report Posted June 27, 2015 I have have heard of some shops doing it by cutting access holes and then installing round "inspection covers". You may consider using structural screws and nuts in place of the upper rivets. Not easy, but doable. Quote

David image.jpg It can be done without removing the entire floor. Remove enough rivets to peel/roll the floor forward to gain access. Clarence Quote
Andy95W Posted June 27, 2015 Report Posted June 27, 2015 +1 Did mine 2 years ago. I used a combination of rolling and in one place, cut a hole in the baggage floor which I then patched. I got the hole idea after talking to Paul Loewen at LASAR. Quote
JaredDavis Posted June 27, 2015 Report Posted June 27, 2015 We followed Clarence's advice and it worked out well. Had to remove the rivets on the aft edge, some on the sides and supports. Quote
Sabremech Posted June 27, 2015 Author Report Posted June 27, 2015 Thank you for the information. I'll have to weigh both options and decide which way to go. David Quote
orionflt Posted June 27, 2015 Report Posted June 27, 2015 when I did mine, I did what Doc suggested remove enough rivets to allow you to rollback the baggage floor. also if you intend to reinstall solid rivets make sure you have a friend available to help buck them. Brian Quote
Alhall Posted June 27, 2015 Report Posted June 27, 2015 When I did mine I removed the floor from the front. The floor is riveted to an angle that is bolted on each side. The bolts are hard to get to. I removed I think about 10 rivets on each side the propped the floor up with pieces of wood. Quote
Mooney1 Posted June 7, 2019 Report Posted June 7, 2019 Just found out that I get to do this on my F now. Quote
Yetti Posted June 7, 2019 Report Posted June 7, 2019 What year F? After some point I think the doubler came from the factory installed Quote
MoonFlyer68 Posted June 7, 2019 Report Posted June 7, 2019 My 1968 F is in annual right now and they found this issue on mine. They are already in the process of doing the repairs. Being my first ever annual with the plane I took it to a Mooney Service Center. I know it is going to cost me more but I also know it will be right when it comes back. Quote

Expand This MSC might never have seen this Service Bulletin before. Frankly, they might never have seen a pre-201 before for that matter. If that’s the case, you’re better off having someone like me or Sabremech do the job Then again, it could be DMax or LASAR, in which case you’re in good hands. The devil is in the details. 2 Quote
carusoam Posted June 8, 2019 Report Posted June 8, 2019 Pics of good cracks in this particular spar have been posted around here before... Put this on the list of things to look for when your friend is buying a Mooney. Overspeed for flaps is real according to the cracks... Every now and then there will be a discussion of... is it OK to lower the first amount of flaps like I did on a C152.... You can, but the cost is a bit high... (pure unadulterated sarcasm....) Post pics if you can... Best regards, -a- Quote
Skates97 Posted June 8, 2019 Report Posted June 8, 2019 Mine had it done a couple owners ago in November 2002. Cracks were found during annual that year according to the log book. Quote
