LCAS’ fully certified (Supplemental Type Certificate) nose-mounted transition and boom assemblies carry the magnetometer sensor and requisite electronics. This modification consists of an externally mounted aluminum transition pylon assembly and brace assemblies witch support a composite boom assembly.

The forward part of the boom assembly contains the provisions for the magnetometer sensor and the aft section houses the amplifier and flux gate.  The orientation of the sensor is adjustable, to provide optimum coupling with the earth’s magnetic field. This innovation eliminates the traditional towed bird system and offers significant advantages in data quality, pilot work load reductions, survey flight efficiencies, and safety in all types of terrain.

The aircraft can be flown with the just transition tube pylon assembly and first section of boom installed. When only the first boom section is installed the end cap from the removed section is used to close off forward end of the remaining section. The mod kit includes all the necessary doublers, support assemblies and attaching hardware, as well as leading edge and trailing edge fairings for the transition assembly.
