MAINTENANCE PRECAUTIONS
The establishment of safe maintenance
procedures is necessary to ensure safety
of personnel and prevent damage to the
aircraft when performing fuel system
maintenance. The principle precautions
that should be enforced are as follows:
A. Perform fuel system maintenance in
an approved work area.
B. Ground aircraft and maintenance
stands to a common ground. Ground
points must not be painted.
C. Remove external power sources and
disconnect batteries.
D. Suspend all maintenance except fuel
system maintenance, unless area is
declared safe from explosive vapors.
Aviation gasoline is
extremely volatile and
vapors accumulate
rapidly if there is no
wind. These vapors are
heavier than air so they
settle into low spots. In
some concentrations the
vapors are extremely
explosive.
E.
Ensure that fire-extinguishing
equipment is readily available.
F. Use air-driven power tools only.
WARNING!
