I fitted the horizontal tail today and noticed a 1/8” gap at the front spar to bulkhead. I have seen shims called up in the IPC and was surprised that none were present.
My questions are:
1. Should there be shims fitted.
2. Are they a part or do I make them myself.
Thanks in advance.

Re: Horizontal Tail Attach
The IPC for 170-B shows them in Fig 14, Items 3 and 4. They are illustrated to be small, squares of PN: 0430010-1 being .20 and and PN: 0430010-2 being.30 stock. Make your own, would be my thought but I'm sure Cessna will be happy to sell you some.

Re: Horizontal Tail Attach
You’ll want to fit things carefully here. Use clay putty to measure gap with H/S fitted with rear bolts installed and vertical stab fitted with bolts. Remove components and carefully measure gap

Re: Horizontal Tail Attach
Reminds me of a time long ago when rebuilding engines and using Plastigauge to check bearing clearances. Not sure if that would work in this application or not.c170b53 wrote:You’ll want to fit things carefully here.
