I received a notice in the mail. It says,

"If your Lycoming engine has a diaphragm-type fuel pump with Lycoming
P/N LW-15473 installed, and has a date code of 3201, the pump must be
replaced PRIOR TO NEXT FLIGHT."

The defective pumps were shipped from Lycoming between 10/1/01 and
2/2/04.

It affects a wide range of engines from 320 to 540, IO, O, AIO, TO



I got that last year and check. I passed! (O-360)
