(3) REPAIR OF DEICER LEAD STRAP (Refer to figure 13)
Use B.F. Goodrich Field Repair Kit No. 77-802 which contains rubber patch material sufficient
for several repair jobs. Cements and solvents specified in these directions are not included in the
kit. (Abbreviation MEK in further steps stands for Methylethylketone.) Following steps apply
wherever cementing is specified in text:
(a) Clean area to be bonded or patched with MEK or acetone to remove all grease and dirt. It is
vital that surface be clean for good cementing job. After last wipe with cleaner, quickly wipe
surface with clean dry lint-free cloth to remove solvent film.
(b) Apply one even coat of 1300L cement (Minnesota Mining and Mfg. Co.) to area to be bonded
or patched and allow to dry (approximately one hour above 40F). Apply second even coat of
1300L cement and allow to dry.
(c) Cut the patch (.020 thick rubber to about 1/4 inch large on all sides of damaged area).
Protective paper is on side to be cemented. Apply masking tape on open side to prevent patch
from curling as cement dries; then strip off protective paper and apply 1300L cement in
smooth, even coat. Allow to air dry. After one hour, apply second coat and allow to air dry.
(d) With cemented surfaces either dry or with just a trace of tackiness, apply light coat of MEK
or Toluol over these surfaces to re-tackify and quickly complete the cementing job as directed.
Allow one hour to air dry before peeling off masking tape or mylar coating on air side. Rub
edges and center of patch to see that it is holding before releasing for flight. (Approximately
24 hours.)
Do not touch cemented surface with dirty or oily fingers.
