GTP 59 Probe Installation in Composite Aircraft
For composite aircraft, the GTP 59 probe cannot be mounted on the fuselage and must be
mounted on an access panel or inspection cover, in a zone 3 area of the aircraft per APPENDIX F. If the
access panel or inspection cover is conductive, a non-conductive doubler must be used
and a minimum 0.5 inches of clearance maintained between the GTP 59 probe/terminal lug and
any conductive element of aircraft structure. Typical installation examples are shown in Figure 4-47 and
Figure 4-48.
