ACCUMULATOR (P/N 242.1B) - Serviceable

The 242.1B is a gas-charged hydraulic accumulator for aircraft emergency brake systems. This component stores pressurized hydraulic energy and dampens pressure spikes to maintain stable system pressure during operation. The accumulator uses a piston or bellows design per SAE ARP4553/ARP4378 standards within AS5440-compliant systems.

Installed in brake circuits, it provides energy reserve for emergency braking when engine-driven hydraulic pumps are unavailable. Requires inert-gas precharge and periodic functional leak checks by qualified maintenance personnel per aircraft maintenance manual specifications.

What is the ACCUMULATOR (P/N 242.1B)?

The 242. 1B is a gas-charged hydraulic accumulator for aircraft emergency brake systems.

What hydraulic fluid type is the 242.1B compatible with?

Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the ACCUMULATOR against your aircraft maintenance manual for fluid compatibility.

Does the 242.1B come pressure-tested and certified?

Overhauled and repaired hydraulic components are pressure-tested per manufacturer specifications and include 8130-3 documentation. The ACCUMULATOR is available in: Serviceable. Contact us for test documentation on your selected condition.
