placed in service, (2) within 30 days after completion of
regular overhaul, and (3) whenever a change in military
characteristics (including any change in weapons
installations) is made. The engineer officer must make
certain that the current revision of the Ship
Characteristics Card is used to submit the report. When
filled in, the Ship Characteristics Card is classified
Confidential.
MAIN PROPULSION TURBINE
CONDITION REPORT
The Main Propulsion Turbine Condition Report is a
letter report of the condition of each propulsion turbine
and is submitted to NAVSEASYSCOM via the type
commander 3 months before each regular overhaul. The
report includes data and information on the turbines
according to NAVSEASYSCOM requirements
pertaining to main propelling machinery. The report
includes recommendations by the commanding officer
and type commander that the turbine should or should
not be disassembled for inspection and overhaul during
the regular period.
When the type commander’s endorsement on a
turbine condition report recommends disassembly of
the turbine casing, NAVSEASYSCOM reviews and
normally approves the recommendation. However, the
type commander may ask for additional information or
alternate or additional tests and inspections before he
approves disassembly of the casing. When the turbine
report shows the condition of the turbine is satisfactory
and no urgent alterations are necessary,
NAVSEASYSCOM does not answer the report. Any
answer from NAVSEASYSCOM that approves
disassembly or asks for additional tests or inspections
will be directed to the type commander with copies to
the reporting ship, the overhaul activity, and any other
activities concerned. The activity (usually the type
commander) controlling the
overhaul funds of the ship,

GAS TURBINE SERVICE RECORDS
The gas turbine propulsion plants recently
introduced to the fleet are unique in that service and
maintenance records are kept in a way similar to aircraft
propulsion plants. NSTM, chapter 9416 (0234), gives a
description of these service records and full instructions
for maintaining them.
