SY5.960.035

SY5.960.035 wire cassette for onboard voice recorders

SY5.960.035 is a replaceable wire recording cassette used as a recording medium in onboard aircraft wire tape recorder systems. The cassette contains a steel magnetic wire carrier and is intended for recording crew voice information, radio communication signals and time signals during flight. It is used as an aviation technical item and can be supplied as part of a complete recorder set or separately as a spare part for operation, repair and maintenance.

Recording medium of SY5.960.035

The SY5.960.035 cassette uses a thin steel magnetic wire as the recording medium. In the P-503B system, the wire is used for magnetic recording of voice and time information in continuous cyclic mode. During operation, the recording process overwrites earlier data as the loop continues, preserving the latest recorded information. This type of cassette belongs to the older generation of onboard recording equipment used before modern solid-state recorders became common.

SY5.960.035 in the P-503B recorder system

The SY5.960.035 cassette is installed directly into the UZ P-503B recording unit. It is an essential consumable and replaceable element of the P-503B onboard wire tape recorder system. The recording unit performs the mechanical and electrical recording process, while the cassette provides the physical wire medium required for storing voice and time signals. Proper cassette condition is important for stable movement of the wire, recording quality and preservation of recorded information.

Application with P-503B and related recorders

The SY5.960.035 wire cassette is primarily associated with the P-503B onboard wire voice recorder. It may also be referenced for use with onboard recording systems such as MS-61 / MS-61-04 where applicable by documentation. These systems are used on Soviet and Russian aircraft and helicopters, including Mi-8 / Mi-17 family helicopters and other aircraft equipped with compatible wire recording equipment. Applicability should always be checked against the recorder passport and aircraft documentation.

Maintenance and replacement of SY5.960.035 cassette

The cassette is used during operation and maintenance of onboard voice recording systems. It may be replaced during scheduled service, repair, inspection or recorder preparation. When selecting a cassette, the recording medium condition, wire integrity, storage condition and compatibility with the installed recording unit should be checked. The cassette should be handled according to the recorder documentation, since damage to the wire medium or cassette mechanism can affect recording continuity.

Identification and ordering of SY5.960.035

The cassette may be referenced as SY5.960.035, СЫ5.960.035, P-503B wire cassette, кассета П-503Б, проволочная кассета П-503Б or Wire Cassette P-503B. These names refer to the same type of replaceable wire recording cassette. For correct supply, it is useful to specify the installed recorder type, required condition, cassette quantity, documentation requirements and whether the cassette is needed for the P-503B system or another compatible onboard wire recorder.
