(2) If the oil pressure was continuously more than zero, during the engine windmilling (after an IFSD), do the inspections that follow:
NOTE: During windmilling, the oil pressure indications can be
____ low or unreadable, (below 40 psi (276.0 kPa) which is permissible if oil temperature conditions are within limits (AMM 71-00-00/201: Engine Operating Limits).
(a) Examine the main oil filter element (AMM 79-21-05/601) and the magnetic chip detectors (AMM 79-21-10/601) for contamination (chips). 1) If you find some metal particles, keep the particles and do
the Oil System Contamination Inspection (AMM 72-00-00/601) prior to further flight.
2) If no chips are found on oil filter or on any of the six chip detectors, reinstall the magnetic chip detectors and a cleaned oil filter (AMM 79-21-05/401, 79-21-10/401).
(b)
Do the Engine Oil Servicing procedure (AMM 12-13-03/301).
(c)
