5.5 GUARANTEE MATERIAL INSPECTION/FINAL CONTRACT TRIALS. GMIs/FCTs are scheduled by the
TYCOM and conducted by the INSURV Board after shakedown, prior to the end of the guarantee period. These
inspections/trials provide a formal evaluation of the material condition of each newly constructed ship after limited
service. GMIs/FCTs are conducted sufficiently in advance of PSA to allow "lead time" for the procurement of
material and the advanced planning required for the correction of deficiencies during the availability. The CO will
present the ship's material status to the INSURV Board following the guidance in Appendix C of this chapter. GMIs
are conducted for submarines; all other ships will undergo an FCT.
5.6 POST DELIVERY DEFICIENCY ITEMS. The CO is responsible for reporting deficiencies not otherwise
identified by INSURV, until the end of the SCN period in accordance with the following procedures. By using the
same format for PDDI reporting as for INSURV items and by extending the use of the Consolidated Report to
include these items, the same management attention is afforded to all construction deficiencies.
a. The following types of problems should be reported as PDDIs:
(1) Recurring failures in a piece of equipment or machinery such that the reliability is considered
unsatisfactory.
(2) Major equipment or component malfunction which requires outside assistance to correct
(vendor or industrial activity).
(3) Symptoms of major machinery problems which require investigation to determine the extent of
the problem. (Improper temperatures, pressures, leakage, vibration, noise, etc.).
(4) Insufficient supply support for specific equipments or machinery based on operational
experience. Allowance deficiencies reported as PDDIs should be supplemented by submission
of Allowance Change Requests/Configuration Change Reports as appropriate.
(5) Excessive or accelerated wear, erosion, or corrosion determined through inspection.
(6) Improper bonding of preservation on surfaces that must be protected.
(7) Any casualty which results in a Casualty Report (CASREP). Insert an amplification data set
immediately after the Parts Identification data set consisting of "AMPN/PDDI:___- ___//",
ensuring that the CASREP includes all appropriate PDDI addressees. A separate PDDI must
also be submitted.
(8) Identification of any condition or defect which requires a Departure from Specification
request.
(9) Improper alignment, clearance, or resistance to ground which indicates an unaccounted for
change from baseline data.
(10) Significant internal and external valve leakage. (Primary, seawater, steam, air, hydraulics,
etc.).
(11) Any significant AT/CT deficiency item reported corrected which has recurred. Refer to the
AT/INSURV number in the text of the deficiency description.
