A word of caution, when ordering and installing the oil filter for your engines: Due to the shorter length of the filter, the filter for the TPE331 can be inadvertently installed in the TFE731 engine. Under certain conditions, the oil bypass may open allowing unfiltered oil to circulate through your engine. We recommend that you check both the size and the part number of the filter that you are using. The correct filter part number is 3070945-1.

ATA 71

For the proper technique for checking your engine oil after several days of inactivity, motor the engine over before you check the oil level. Do this and you will not needlessly over-service the oil reserve. This is not for aircraft that are in regular use.
