  <p>Based on Bricklink's <a href="https://www.bricklink.com/catalogItemInv.asp?S=42145-1" rel="nofollow noreferrer">inventory for 42145</a> set liftarm/beam isn't the only extra &quot;extra&quot; piece you have. Your &quot;extra&quot; also includes:</p>

Answers.Text: One time I tried having an extra piece which was not even in the set. Not a giant one, but larger than those which are normally extra. However, another piece about the same size was missing. I assume that was why it slipped through the weight QA.

  <p>The usual assortment of 1x1 tiles, bushings and connector pins.<br />
  <em>But that lift-arm piece?</em><br />
  I'm 100% certain it really is an extra. The build uses 6 of these and they are all in places were it is impossible to forget one without noticing that straight away.<br />
  This one was &quot;left behind&quot; when putting together stage 4 of the build.</p>
  <p>I never have seen a extra lift-arm (or regular bricks larger than a 1x1) in any set and I must have build over a 100 by now.</p>
  <p>Has anyone seen such a large brick as extra before or did I just get lucky?</p>

Comments.Text: You can easily verify they're actually included in the build : 4 should be immediately visible - 2 right above the cockpit, and 2 at the base of the rudder (affixing it to the tail boom). The final 2 form part of the internal structure of the tail boom (right next to the motor, covered by slanted panels saying "S.A.R." on the sides - you should be able to spot them from the bottom though without having to take it apart.

  (Asked by: username_0 on 2024-04-06)
  
  So I just finished building set 42145 (Airbus Search & Rescue helicopter).
  In the picture below you see the left-over "extra" pieces.

  *But that lift-arm piece?*  
  I'm 100% certain it really is an extra. The build uses 6 of these and they are all in places were it is impossible to forget one without noticing that straight away.  
  This one was "left behind" when putting together stage 4 of the build.
  
  I never have seen a extra lift-arm (or regular bricks larger than a 1x1) in any set and I must have build over a 100 by now.
  
  Has anyone seen such a large brick as extra before or did I just get lucky?

  It is pretty much impossible to tell firmly if you built your model correctly without having an option to observe it in person.
  
  Based on Bricklink's [inventory for 42145](https://www.bricklink.com/catalogItemInv.asp?S=42145-1) set liftarm/beam isn't the only extra "extra" piece you have. Your "extra" also includes:
  
  * 1 x [Technic, Axle 2L with Pin with Friction Ridges](https://www.bricklink.com/v2/catalog/catalogitem.page?P=18651&idColor=11#T=C&C=11)
  * 1 x [Technic, Axle Connector with Axle Hole](https://www.bricklink.com/v2/catalog/catalogitem.page?P=32039&idColor=11#T=C&C=11)
  * 1 x [Technic, Pin with Short Friction Ridges](https://www.bricklink.com/v2/catalog/catalogitem.page?P=2780&idColor=11#T=C&C=11)
