The F402 Engine Series (F402-RR-/406B/408A/408B) utilizes Quantitative Debris Monitoring (QDM) as its

primary oil monitoring system. QDM is performed at a recurring 15 hour interval. NOAP samples are ONLY

required to be obtained in response to specific ODMN triggers/thresholds conditions. Samples should be

processed to determine elemental composition and results recorded on OIL ANALYSIS REQUEST form. Return

results to the requesting activity without recommendations or advice codes. QEM/NOAP procedures and limits

are contained within the F402 Engine Standards Practices Manual, A1-F42B-SPM-000. All NOAP samples

submitted are to be considered special samples. Results are to be transmitted to the submitting activity via phone,

facsimile, or e-mail.
