Cessna 402 Fleet Grounded

[Charles Talleyrand]

Cape Air, a local airline based in Hyannis, Mass., on Tuesday
voluntarily grounded 34 of its 49 Cessna 402 piston twins after
experiencing three engine failures in three weeks. "Several recent
engine abnormalities have led us to examine the wear-rate in one of
the engine components ... ... The unusual wear pattern on these parts
has to be fixed" the company said.

Does anyone know what's going on?

Avweb has another blurb out today about it being abnormal wear on the
crankshaft counterweights. The 402B has a TSIO-520-EB 300 HP Continental
and the 402C a TSIO-520-VB 325 HP Continental engine.

Also was mention that the company told the pilots to run the engines at a
lower cruise RPM. After they did that they started having problems...
