JOINT FLEET MAINTENANCE MANUAL

6.4.2 Assignment of Escort Ship (Submarines only).
COMFLTFORCOMINST 4790.3 REV A CH-1
a. In accordance with reference (c), the requirement for providing an escort during deep dive submergence
trials upon completion of PSA will be evaluated by NAVSEA on a case basis. NAVSEA will advise
the Fleet Commander (Submarine Force Commander) in writing, whether or not an escort will be
required based on the scope of work in the availability. In general, PSAs should not require an escort,
since the work typically performed in these availabilities is limited in scope, is carefully controlled and
does not result in substantial risk of unidentified or incomplete work adversely affecting the Submarine
Safety (SUBSAFE) boundary.
b. Waiver of escort requirements may be requested by message when necessary. The ISIC will request the
waiver as soon as possible. The TYCOM will pass the request to NAVSEA for approval. An escort
waiver request message will include all of the following specific statements, as applicable:
(1) A ( ) inch by ( ) inch hull cut between frames ( ) and ( ) including a ( ) inch section of frame ( )
was the only major hull integrity work accomplished during the availability. If no hull frame
cut was made, a positive statement to that effect is required.
(2) The hull cut weld satisfactorily passed Radiographic Testing (RT) and seven day Magnetic
Particle Testing (MT) nondestructive tests.
(3) Post repair frame circularity check readings are within specifications.
6.4.3 Assignment of Deep Submergence Rescue System Services (Submarines only). Assignment of Deep
Submergence Rescue System services are to be carried out in accordance with the guidance provided in Volume I,
Chapter 4, paragraph 4.4.3.c of this manual.
6.5 DEFICIENCY CORRECTION PERIOD. A deficiency correction period will be scheduled after Sea Trials and
prior to PSA completion. The scheduled length of this deficiency correction period shall be determined by the type
and magnitude of the remaining deficiencies.
6.6 PERIOD FOLLOWING POST SHAKEDOWN AVAILABILITY. Depending on the PSA contract, the
industrial activity will normally guarantee work accomplished during an availability for a period of 90 days from the
completion of the availability. This does not include responsibility for malfunctioning machinery and equipment
due to normal wear, improper adjustment, or tuning by Ship's Force and failure of limited life components. Ship's
Force is required to report guarantee items to the industrial activity prior to the guarantee period expiration date. If
operational commitments prohibit reporting prior to the 90 day period, the ship should report problems as soon as
operations permit. A message is the preferred method of reporting these items. The message outlining specific
deficiencies should be submitted to the Supervising Authority with a copy to the TYCOM, the ISIC and the Ship
Program Manager who will pass a copy to NAVSEA 04, and to NAVSEA 08 for nuclear cognizant issues.
Additionally, any Casualty Reports (CASREP) submitted during the guarantee period must also be addressed to the
Supervising Authority and the Ship Program Manager with passing instructions to NAVSEA 04, and to NAVSEA
08 for nuclear cognizant issues.
