Q

Transmission Limitations

A

Limited by Nr, torque, oil press and oil temp. If oil press and/or temp are in precautionary range, the helo shall not be scheduled for additional flights until mx action is performed.

NOTE Prolonged hovering in hot weather 95F (35C) and high gross weight may cause temps to rise in the yellow precautionary range. Operation in the precautionary range for less than 30 min during any one flight under these conditions is acceptable.

Following conditions do not constitute an emergency situation, but may be indicative of a degraded lubrication system. Any discrepancy shall be documented on a MAF.

  1. Steady press outside 45-60psi, but within normal limits.
  2. Fluctuations not to exceed a range of 10psi, within the normal limits.

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