Hartzell Engine Tech V-Band Clamp 490127-0001 - Continental
MFR Model# 490127-0001
Overview
|
FAA-PMA Turbo Exhaust Clamp for Continental TSIO / TIO Series Engines The AeroForce 490127-0001 V-Band Clamp is an FAA-PMA approved replacement for Continental turbocharged engines including TSIO-360, TSIO-520, TSIO-550, and related models. This clamp secures the exhaust-to-turbocharger flange connection, helping maintain proper exhaust sealing in high-temperature turbo applications. A compromised V-band clamp can lead to exhaust leakage, turbocharger performance loss, carbon monoxide risk, and potential engine power loss. AD 2023-09-09 placed a 500-hour life limit or recurring inspection requirement on many spot-welded V-band clamps. The Hartzell PMA clamp is not subject to this AD, offering Continental operators a durable alternative without recurring life-limit replacement. Replace the clamp if any of the following conditions are found:
Note: Inspect at each 100-hour, annual, or condition inspection per Hartzell Engine Technologies
