Navigation Unit Fails Soon After Repair

June 2009

Duncan Aviation recently saw a Nav unit in our avionics shop that failed soon after being repaired by another service provider.

A Duncan Aviation technician found some screws had been installed incorrectly. The previous shop had swapped some longer and shorter screws, screwing the longer ones into an incorrect location, driving them into a circuit board; it took only a short time after installation for the unit to fail.

We caution our customers that experience in component service can make a big difference in the reliability of a component, and ultimately the reliability of an aircraft.
