V-Band Clamps

• Are these AeroForce clamps affected by the AD?

  No. These clamps are not spot-welded and are not subject to the requirements of AD 2023-09-09.

• Should the exhaust gasket be replaced when installing a new v-band clamp?

  Yes. Any time the exhaust or turbo flange joint is separated, the gasket or fire ring should be replaced and the mating surfaces inspected. Browse the McFarlane website to find gaskets applicable to your aircraft or engine.

• What does the safety cable do?

  The cable provides a backup restraint to help prevent clamp separation if the primary band were to loosen or fail.

• What is AD 2023-09-09 and how does it affect v-band clamps?

  This AD applies to spot-welded turbo v-band clamps and introduces a 500-hour life limit or repetitive 100-hour/6-month inspections due to fatigue cracking and separation risk. The AeroForce v-band clamps from McFarlane are not subject to the AD.

• What makes these clamps different from the OEM clamps?

  They use a reinforced band design with an integrated safety cable for secondary retention and are not life-limited by the AD
