8A-5301-220-3

Onboard system and operating function

Confirmed list assignment: Hydraulic System. This classification identifies the applicable system section but does not independently establish a circuit branch or interchangeability with a neighbouring position. One helicopter can use visually similar assemblies that differ in length, reinforcement, fittings and operating limitations.

The product maintains a sealed flexible path for the approved working medium between connected system parts. Working medium for the confirmed group: Not specified for this exact position in the supplied Offer List. Allowable pressure, temperature, minimum bend radius and assigned life for the exact execution must come from its passport, controlling drawing and current documentation for the applicable helicopter modification.

Part Number, normal and OST checks for 8A-5301-220-3

New-edition normal or OST: No separate new-edition normal is recorded. Alternative search designations: Not specified. Technical specification or construction type: Exact normal, OST or drawing recorded in the supplied list. These forms remain on one page when the source material shows that dotted, zero-padded or differently spaced records identify the same physical hose position.

Retain every digit, point, hyphen and letter suffix in an inquiry. Different lengths, base normals and suffixes are catalogued as separate products. A matching appearance, partial designation or single dimension does not demonstrate that another hose is an approved replacement.

Inspection, installation and documentation

Incoming inspection should verify the Part Number, normal, OST reference, YOM, flexible body, ferrules, fittings, protective caps and internal cleanliness. Check for cracking, kinking, swelling, corrosion, contamination, damaged threads and evidence of unsuitable storage. The representative photograph shows aviation hose assemblies and does not confirm the individual marking of a particular supplied unit.

Compare removed and supplied assemblies by controlled length, internal diameter, connection hardware, fitting angles and relative orientation. An installed hose must not be twisted, sharply bent, routed against an edge or hot surface, or interfere with adjacent equipment. Use the helicopter installation documentation to establish bend radius, clearances, supports and clamp positions.

Reliable dimensions, mass, exact operating pressure, temperature range, assigned life and storage limit for this execution were not found in the available sources. These values must not be copied from a neighbouring position or inferred from the photograph; confirm them through the product passport, certificate, drawing and aircraft documentation.

Before confirming an order, the operator or maintenance organization should compare the marking on the removed sample with the parts catalogue and records for the specific helicopter. If the marking is damaged, include clear photographs of both fittings, ferrules and the overall relaxed length. This check helps distinguish neighbouring executions and prevents selection of a visually similar hose without documented approval.
