MAIN XMSN OIL PRESSURE |
MAX 130 psi PRECAUTIONARY 65-130 psi CONTINUOUS 30-65 psi IDLE & TRANSIENT 20-30 psi MINIMUM 20 psi During steady state level pitch attitudes the transmission oil pressure should be 45-60 psi. The following do not constitute an immediate emergency situation but may be indicative of a degraded lubrication system. Any discrepancy shall be documented on a MAF. 1. Steady pressure outside of 45 to 60 psi, but within the normal limits of 30 to 65psi. 2. Fluctuations not to exceed a range of 10 psi, within the normal limits of 30-65 psi. |
