CHIP DETECTORS

Two chip detectors are installed on the engine, one on the underside of
the reduction gearbox case and one on the underside of the accessory
gearbox case. The chip detectors are installed to trigger an amber
CHIP DETECT annunciations anytime metal chips are present in one
or both of the chip detectors. Illumination of the amber CHIP DETECT
annunciator indicates the need for engine inspection for abnormal
wear. The amber CHIP DETECT annunciation will also be shown if
either chip detectors electrical connector has come loose. The engine
oil must be drained prior to removing either of the chip detector
sensors. Refer to the 208 Maintenance Manual, for more information
on inspection and removal of the engine chip detectors.

OIL BREATHER DRAIN CAN

Model 208 airplanes have an oil breather drain can mounted on the
right lower engine mount truss. This can collects any engine oil
discharge coming from the accessory pads for the alternator drive
pulley, starter/generator, air conditioner compressor (if installed), and
the propeller shaft seal. This can should be drained after every flight. A
drain valve on the bottom right side of the engine cowling enables the
pilot to drain the contents of the oil breather drain can into a suitable
container. The allowable quantity of oil discharge per hour of engine
operation is 14 cc for airplanes with air conditioning and 11 cc for
airplanes without air conditioning. If the quantity of oil drained from the
can is greater than specified, the source of the leakage should be
identified and corrected prior to further flight.
