2. TECHNICAL SERVICE BULLETIN FOR HEATED AOA/PITOT
PROBE
On May 6, 2014, Dynon Avionics issued a Technical Service Bulletin that discussed an issue with
previously-manufactured Dynon Avionics Heated AOA/Pitot Probes (P/N 100667-000). It was
subsequently updated in October 2014 with instructions to obtain a redesigned probe that fixes
the identified issue. Customers that have Heated AOA/Pitot Probes that are affected by this
Technical Service Bulletin should not proceed with installation. Your probe should be replaced
via Dynon’s Heated AOA/Pitot Probe replacement program.

If you are installing a Dynon Avionics Heated AOA/Pitot Probe,
ensure that the unit you have is not affected by the Technical
Service Bulletin by comparing your probe to the illustration at
right. Orient your probe snout up, looking at the bottom side of
the Probe opposite the mounting “elbow”.
If your Dynon Avionics Heated AOA/Pitot Probe matches the
illustration at right – has two pin-size drainage holes along the
centerline, directly behind the snout, your unit is not affected by
this Technical Service Bulletin and no action is required; continue
the installation.
