Q

XMSN Oil Temp Paragraphs (verbatim, you moron)

A

During any operating condition, no mx action is required if main XMSN oil temp is in the precautionary range continuously for 5 min or less.

Prolonged hovering in hot weather 86F (30C), may cause main XMSN oil temp to rise into the precautionary range. Operation in the precautionary range for no less than 30sec in one flight under this condition is acceptable and no mx action is required.

Q

XMSN Oil Px Paragraphs (make Yuri proud)

A

During steady state level pitch attitudes ( level flight) the XMSN oil Px should be 45-60 psi. The following conditions 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 state pressure outside of 45-60 but within the normal limits of 30-65
2. fluctuations not to exceed 10 psi, within the normal limits of 30-65.

During transient pitch up or steady state nose high pitch attitudes (autos, downwind hovering, rearward flight, slope landings) XMSN oil Px fluctuations (including momentary fluctuations below 30 psi and transient droops below 20 psi for up to 1 sec) are acceptable. Operating with Px fluctuations below 30 psi shall be limited to 30 min.

During rotor engagement, a zero oil px indication may indicate a no oil flow condition through the lubrication system. Operating with a no oil px indication shall be limited to 1 min and shall be documented on a MAF
