condition rather than age. Equipment passing required inspections shall remain in
service indefinitely, since inflation tests and inspections by using activities clearly
show leakage caused by abrasion, porosity, deterioration, etc.

The Preflight Inspection shall be performed prior to each flight by the aircrew member to whom the life raft is
assigned, or by ALSE personnel prior to issuance to crewmember.

vice, during every inspection cycle, and whenever an inflation assembly is replaced. The leakage test shall be per-
formed during every inspection cycle. Unless operational requirements demand otherwise, the life raft inspection
shall be performed by ALSE personnel.
