Bushing

August 27, 2014 - 2:10pm

Metallized Carbon (Metcar), a manufacturer of oil-free, self-lubricating, carbon-graphite materials for severe-service lubrication applications, has announced its carbon-graphite bushings are available for use in gear pumps that pump aviation fuel for aircraft engines. The carbon-graphite bushings, which are used to support both the drive gear shaft and the idler gear shaft, are preferred for that application because they can use aviation fuel as the bushing lubricant.

The FAA is proposing to supersede an existing airworthiness directive for the Agusta A109E that requires reducing the tail rotor (T/R) blade life limit, modifying a T/R hub and grip assembly, re-identifying two T/R assemblies, clarifying the never-exceed speed (Vne) limitation and reducing the inspection interval. The OEM has since redesigned a T/R grip bushing that reduces the loads, which caused cracking on the T/R blades.
