Need to install heated pitot tube on 170B

Post by Collin Gyenes »

Hi,

Can anyone give some help on installing heated pitot tube. Is it best to get the bracket from wreaked 170/172? And where to buy bracket and tube. Also what size (amp) breaker need for power.

The heated pitot for the 170 was originally a Kollsman unit. The type certificate lists the pn that was originally approved. It looks like a C-190/195 unit (sort of like a re-fueling probe.)
The later, "L" type heated pitot is sometimes installed, as you have indicated, usually salvage units for cost reasons. Some sort of approval will have to be made to keep it legal, either a field approval or STC.
TIC170A has paperwork and 337's etc. available.
