Record) shall be initiated/updated in accordance with DA PAM 738-751.
The service life for inflatable survival equipment shall be determined by

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.
All LRU-18/U decapitalize letters as required life rafts and containers shall be subject to the initial inspection prior
to placing in service. The inspection cycle thereafter shall be every 360 days. In no case shall the interval exceed
366 days for the LRU-18/U. The functional test shall be performed prior to placing the LRU-18/U life raft in ser-
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.
