NATURE OF PROPOSAL '
21
Note: Four aircraft (352, 355, 358 and 378) will be modifi 'by addition
of VCR and by replacement of the PM-6 with the ARN-59 ADF system. This
25X1A
configuration allows a weight savings of 6 pounds.
1. The ADF Loop and VCR Antenna will be housed in an all plastic nose,
eliminating the need for an external VHF antenna.
The Ap/ARN-30 VCR Receiver and ARC type B-18A RMI Converter will be
installed in the nose area forward of the 618T-3 transceiver pressure
box. This area is resent designated as "alternate" provisions
for system VI Power Supply". a bracketry will
be such to allow convenient installation of .e th the Vet units
or t .8yAt ,_W units, but not simultaneously.
2. The ADF and VCR controls will be located on the R.H. side console.
Mark III hand controls will be required. The contractor understands
that the subject aircraft are equipped with these controls. It not,
aircraft with other than Mark III controls must be modified by
installation of Mark III controls.
3. The stand-by compass will be relocated to the right hand upper area
of the center instrument panel. The VCR indicator will be installed
in the area presently occupied by the stand-by compass.
4. The sense antenna will be reworked to provide improved operation, as
determined by previous flights on FOG aircraft.
5. Prepare and issue a Service Bulletin and manufacture the necessary
kits.
NOTE: 1. We to "tight" scheduling, the installation of the VCR system
cannot be done at the factory during time of conversion.
2. Due to complexity of this change, it is recommended that this
modification be accomplished at the factory at a later date.
