SECTION I. GENERAL
10-1. INTRODUCTION . This chapter provides
methods for assessing battle-damage, deferring damage
repair, and repairing fuel systems. The primary
emphasis is on providing the assessor with the proper
Simplified logic trees and related illustrations will also
aid the assessor.
SECTION II. DAMAGE ASSESSMENT
10-2. DAMAGE ASSESSMENT PROCEDURE. Each
fuel tank must be carefully evaluated and classified.
Examine both confined areas and open areas exposed
to the airstream. Determine which leaks require
immediate repair before flight and which leaks are not a
flight hazard. Determine the exact location of a leak
and thoroughly examine the leak area. Refer to Figure
10-1 for assessment logic.
10-3. DEFERMENT. Scheduled maintenance may be
deferred. Unscheduled maintenance such as the repair
of systems and subsystems which are not critical to
mission accomplishment, may be deferred if safety of
flight is not significantly degraded. Requirements must
be examined to determine if relaxed standards for repair
and aircraft performance can be accepted. The
commander may defer combat maintenance and battle
damage repair, even if doing so places operational
limitations on the aircraft.
SECTION III. BATTLE-DAMAGE REPAIR
10-4. FUEL TANKS. Battle-damage repair of fuel
tanks is limited to those repairs specified in this manual.
10-5. FUEL SYSTEM SEALS. Preformed packings
removed during fuel system component maintenance
may be reused if they are not damaged or swelled to a
point where they do not fit snugly into the preformed
paddngs groove. Swelled preformed packings may be
reused if they are allowed to dry and shrink to the
original size. Seals composed of rubber inserts may be
reused if they are not damaged or if compression set is
not more than 60 percent when compared with a new
Reused preformed packings and
seals must be inspected after every
flight for leakage until replaced.
