NTSB Safety Recommendations M-12-1 through -3

************************************************************

The National Transportation Safety Board makes the following safety

recommendations to the U.S. Coast Guard:

Require new-construction U.S.-flag passenger vessels with controllable pitch

propulsion, including cycloidal propulsion, to be equipped with alarms that

audibly and visually alert the operator to deviations between the operator's

propulsion and steering commands and the actual propeller response. (M-12-1)

Where technically feasible, require existing U.S.-flag passenger vessels with

controllable pitch propulsion, including cycloidal propulsion, to be

retrofitted with alarms that audibly and visually alert the operator to

deviations between the operator's propulsion and steering commands and the

actual propeller response. (M-12-2)

Require all operators of U.S.-flag passenger vessels to implement safety

management systems, taking into account the characteristics, methods of

operation, and nature of service of these vessels, and, with respect to

ferries, the sizes of the ferry systems within which the vessels operate. (M-

12-3)

The National Transportation Safety Board reiterates two recommendations

previously issued to the U.S. Coast Guard, as follows:

Require installation of voyage data recorders that meet the international

performance standard on new ferry vessels. (M-10-5)

Require installation of voyage data recorders on ferry vessels built before

the enactment of voyage data recorder carriage requirements that will record,

at a minimum, the same video, audio, and parametric data specified in the

International Maritime Organization's performance standard for simplified

voyage data recorders. (M-10-6)

The National Transportation Safety Board reclassifies a recommendation

previously issued to the U.S. Coast Guard, as follows:

Seek legislative authority to require all U.S.-flag ferry operators to

implement safety management systems, and once obtained, require all U.S.-flag

ferry operators to do so. (M-05-6)
